and price estimations

Abstract
In five studies we show that the introduction of the Euro influences price estimations and the
perception of salaries among people in Germany. People confronted with wages given in Euros
compared to the German Mark (DM) showed a reduced willingness to face long distances to get to
work when accepting a job offer. When asked to price various consumer goods appropriately, they
estimated higher prices if they used the ‘Euro’ currency compared to price estimations made in DM.
This phenomenon only occurred with regard to the Euro, but not in comparison with other currencies
(cf. the British Pound and Austrian Schilling). The differing price estimations between the Euro and
the German Mark were not influenced by participants’ attitude towards the Euro. Moreover, it turned
out that they depended on how the judgement context was framed. Only if participants expected to
make price estimations for shops in their home country, Germany, did the familiar nominal DM
figures serve as an anchor heightening the estimated prices in Euro. The same effect disappeared
if participants were instructed to make their price estimations for shops in a foreign country
(Ireland). Copyright # 2002 John Wiley & Sons, Ltd.
Although the Euro has been an economic reality since 1999, from a psychological point of view the
actual introduction of the new notes and coins at the beginning of the year 2002 might be of more
importance for the citizens, because from that time on they are physically confronted with the Euro in
everyday life (Dehm & Muller-Peters, 2001; Pepermans, Burgoyne, & Muller-Peters, 1998). It is
unclear how people will react to the new currency. It might take a while until people get used to handle
and deal with the new Euros and Cents in everyday life, until employees get used to being paid in
Euros, and until customers are familiar with buying their goods and services using the Euro. Although
the real prices and objective amounts of money for employees and customers remain about the same, it
could make a significant psychological difference for people to be confronted with the new currency as
compared to their former national currency. In this article we will focus on two processes where such
psychological effects of the Euro could appear, namely the perception of salaries (with regard to their
attractiveness) and the estimation of prices.

There are different aspects connected with the introduction of the Euro that could induce a
psychological difference between perceiving salaries and estimating prices in Euro versus in the
former national currency. On the one hand, the nominal values between the Euro and the former
national currency are different, and this nominal difference could influence the perception of prices,
salaries etc. On the other hand, not only does the nominal value change, but also the whole currency
system changes from a national system to one that operates throughout Europe. This loss of national
autonomy and the dependence on other European countries with regard to money issues could
influence the attitude towards the new currency, and this attitude, in turn, could have an impact on the
perception of salaries and the estimation of prices. How could each of the two changes affect the
perception of salaries and the estimation of prices?
The difference in nominal values could give rise to a phenomenon called the ‘money illusion’
(Fisher, 1928; Shafir, Diamond, & Tversky, 1997). Money illusion describes the tendency that people
often think of economic transactions in predominantly nominal terms, because the nominal value is a
salient and natural unit of money. Simply stated, they consider a product as being cheap if the nominal
value of the price is low, and they consider it as being expensive if the nominal value is high. However,
since people are usually aware that there is a difference between nominal and real values, their
evaluations often represent a combination of nominal and real assessments (Shafir et al., 1997). When
people convert their national currency to the Euro, then, depending on the exchange rate, the nominal
value of the Euro will be smaller or larger than the nominal value of the former national currency.
Therefore, prices in Euros may be perceived as higher or lower than prices in the familiar national
currency (Burgoyne, Routh, & Ellis, 1999). Marques (1999) has drawn attention to a related
phenomenon. Since for most member states (except for Ireland) the conversion to the Euro will
lead to prices with lower quantitative values, the quantitative differences between the prices will also
be significantly reduced. This makes it more difficult to compare the prices between different products
and services. It might take a while for the citizens to get used to the fact that quantitative smaller price
differences still mean a large increase in spending.
With regard to Germany, where our studies were conducted, from the year 2002 people will have to
handle unusually low figures when prices are given in Euros instead of German Marks since the
conversion rate is roughly 1 Euro to 2 DM. Thus, even if the real purchasing power of the money does
not change through the monetary reform, for example a salary of 50,000 Euros could be considered as
less attractive than the equivalent amount of about 100,000 DM simply because the nominal figures of
the first are smaller. Similarly, a CD player for about 200 Euros could be perceived as less expensive
than one sold for 400 DM simply because the figures of the first are lower.
In addition, another effect might occur as a result of the difference in nominal values. If people have
reference prices in mind, these reference prices can serve as an anchor in the price perception or price
estimation process (Shafir et al., 1997). Such anchors have systematic influence on subsequent judge-
ments in that, for example, higher anchors lead to higher price estimations (e.g. Northcraft & Neale,
1987). In general, anchoring effects are defined as ‘the assimilation of a judgement to a salient standard
of comparison’ (Mussweiler & Strack, 2000b, p. 1038). The anchoring effect was first described by
Tversky and Kahneman (1974) who showed that deciding whether the percentage of African nations in
the UN is higher or lower than 65% (high salient standard of comparison) leads to higher estimations
than making the first decision for a reference value of 10% (low salient standard of comparison).
With regard to money, several lines of research have documented how price estimations systematic-
ally deviate in the direction of such anchors, and how the perception of prices systematically depends
on the value of such anchors. For example, Northcraft and Neale (1987) have shown that lay persons’
(students’) as well as experts’ (real estate agents’) price estimations for real estate properties were
systematically affected by the listing price of these properties, although the participants
received sufficient information to make their own price estimations independently of this listing
148 Eva Jonas et al.

price. In bargaining research, it is a well-known phenomenon that the first offer serves as an anchor
that systematically affects the height of the first counteroffer (e.g. Kristensen & Gaerling, 1997, 2000).
As a third and final example, if people are first confronted with a high price for a product and,
subsequently, this price is lowered to a more moderate price, they are more willing to buy the
commodity than when they are confronted with the moderate offer to begin with (Burger, 1986). This
can be explained by assuming that the first price serves as a reference price, influencing the perception
of the subsequent moderate price via an anchoring effect (Burger, 1986, Experiment 5).
Such anchoring effects could also affect the perception of prices and salaries after the introduction
of the Euro. Since people are familiar with the nominal values in their former national currency, these
familiar values might be automatically salient and serve as an anchor if people consider new prices or
salaries in Euros. As a consequence, if the former national currency has lower nominal values than the
new currency (Euros)—this is only the case for the Irish Pound—the comparably low anchor values
would decrease price estimations and, in turn, would lead people to perceive the new prices and salaries
as being too high. If, however, the former national currency has higher nominal values than the Euro—
and this is the case for most countries (e.g. Germany and France)—from an anchoring perspective one
would expect the opposite effect. Since the familiar prices (the anchor values) lie above the new prices,
these prices should appear comparatively low, and the same should be true for salaries. If, in turn, these
people are asked to estimate the appropriate price for a given product, they should overestimate this
price compared to people who make the same estimation in their former national currency.
To sum this up, both processes that operate on the change in nominal values from the German Mark
to the Euro, namely money illusion and anchoring, lead to the same prediction. In the case of Germany,
since the nominal values in Euros are lower compared to DM, the same real prices and salaries should
appear lower if they are given in Euro compared to DM. Thus, identical real salaries should appear less
attractive if they are given in Euro than if they are given in DM. In addition, people in Germany should
tend to make higher price estimations if they use the Euro than if they use the DM because identical
real Euro prices appear lower than their corresponding equivalents in DM.
Aside from these effects caused by the changes in nominal values, the change of the money system
itself from a national to an international, pan-European currency could have an impact on processes
like the perception of salaries and the estimation of prices. People might have a different attitude
towards the Euro than towards the old national currency, and attitudes can influence the perception of
money in general and processes like price estimation in particular. Comparing different amounts of
money, Brandstatter and Brandstatter (1996), for example, found that the subjective value of money
was influenced by the participants’ monthly net income and their attitudes towards money. A study in
Poland demonstrates the different attractiveness of the same real monetary values in different
currencies. Ostaszewski, Green, and Myerson (1998) investigated the subjective value of a delayed
reward with the same values but labelled in different currencies, namely old zlotys, new zlotys and
dollars. They found that the subjective value of a reward was valued less when its amount was
specified in old zlotys, which was associated with high inflation rates, than when it was specified in
dollars. This effect clearly exceeded the amount, which could be explained by the decrease in
purchasing power predicted by the actual rate of inflation. Compared to the new zloty, which was
considered to be much more stable than the old zloty, the value of the dollar was no longer considered
as being greater. This finding shows that the rated attractiveness of money is influenced by people’s
attitudes towards the currency.
Even the perception of the size of coins and notes depends on subjective values, as it is evident from
the classical study of Bruner and Goodman (1947), who demonstrated that valuable objects like coins
tend to be perceived as larger than they really are and that this overestimation effect is more
pronounced among poor than among rich children (see also Dawson, 1975; McCurdy, 1956; Smith,
Fuller, & Forrest, 1975; Tajfel, 1957). In times of high inflation rates people underestimate the size of

coins and notes (Furnham, 1983; Lea, 1981; Leiser & Izak, 1987), which can be explained by the fact
that inflation causes a loss of trust in the currency and people develop a negative attitude towards the
currency (Leiser & Izak, 1987). These findings underline that social knowledge and attitudes affect not
only cognition and judgements that have an inherently social nature but also cognition about physical
features such as the size of an object (Stapel & Koomen, 1997).1
Having shown that the perception of a currency is widely influenced by people’s attitudes towards
the currency, the question arises what we know about the attitudes towards the Euro and what could be
the consequences for price estimations and the attractiveness of salaries in Euros. While in Southern
European countries like, for example Italy, Spain or Greece, the attitude towards the Euro is
predominantly positive, the attitude of people in the Northern-Central countries such as the
Netherlands, the United Kingdom, Sweden or Germany is more reserved (Pepermans & Verleye,
1998). This is paralleled by the finding that in the Northern-Central countries, the attitude towards the
Euro can largely be explained by pride in the own national currency; this pride induces an aversion
against losing the national currency (Dehm & Muller-Peters, 2001; Muller-Peters, 1998; Pepermans &
Verleye, 1998; van Everdingen & van Raaij, 1998). In addition, the attitude towards the Euro in such
countries is highly influenced by pride in national economic achievements and the fear of negative
consequences for the economy. The more people feel that the new currency increases the risks for
the national economy, endangers its economic growth, and increases unemployment as well as the
inflation rate, the less the Euro is accepted (van Everdingen & van Raaij, 1998). In addition, a lot of
people expect the economic situation to worsen also in micro-economic terms, i.e. with regard to
wages, prices and interest rates (van Everdingen & van Raaij, 1998 for the Netherlands, Kiell &
Muller-Peters, 1999 for Germany). These findings are in line with social identity theory (Tajfel &
Turner, 1986) since national identity—which manifests itself in history, collective values, achieve-
ments and symbols, such as the currency—is part of the social identity. However, the European
currency and economic change is not much of a threat to the national pride of the Southern European
countries since they seem to express their national pride more through cultural and historical
achievements (Pepermans & Verleye, 1998; van Everdingen & van Raaij, 1998). Therefore, in these
countries, national identity is not going to compete with the European identity (Cinnirella, 1996 for
Italy; Luna-Arocas, Guzman, Quintanilla, & Farhangmehr, 2001 for Spain and Portugal). This is also
in accordance with social identity theory (Pepermans & Verleye, 1998; Tajfel & Turner, 1986), since
groups or nations, respectively, define their social identity on dimensions in which they fare well, when
compared to other relevant groups or nations.
In Northern-Central countries, national currencies as constituent parts of the social identity arouse
commitment and emotional attachment (Helleiner, 1998; van Everdingen & van Raaij, 1998). For
Germany, for example, the site of our studies, the German Mark (DM) is an important national symbol
which stands for a successful history of currency stability, high reputation in foreign countries, and a
rising and stable prosperity in Germany. The Germans’ identity and self-esteem have been, and still
are, tightly interrelated to economic success and the German Mark, which stands for the positive
aspects of German history. National identity in Germany goes hand in hand with economic identity,
which in turn provides the perception of a positive distinctiveness in comparison with other nations
(Dehm & Muller-Peters, 2001; Muller-Peters, 1998).
The introduction of the Euro threatens the identity-giving symbol of the German Mark since after
the introduction of the Euro the DM will disappear as a national symbol. A study by Greitemeyer,
Jonas, and Frey (2001) shows that the DM is regarded as more attractive, stable, and positive in
comparison to the Euro. Even the US dollar is preferred to the Euro and is considered as being more
1Looking at the perception of money the other way round one can find that the perceived value of a currency is influenced by thesize of the coins (Boustead, Cottee, Farquhar, Jonas, Walter, & Webley, 1992) as well as their thickness, colour and elaborationof their edges (Bruce, Gilmore, Mason, & Mayhew, 1983).

attractive and stable. Of all three currencies, the DM is the most preferred. Survey results in Germany
in December 2000 revealed that with regard to the question of whether people are in favour or against
the introduction of the Euro, there were only 47% supporters of the Euro as opposed to 44%
opponents, while 9% did not know (cf. Eurobarometer 54, European Commission, 2000).2
In general, it is justified to say that the majority of the Germans expect the economic situation to
worsen after the introduction of the Euro (Kiell & Muller-Peters, 1999). This negative attitude towards
the Euro could not only lead to the new currency being evaluated as less attractive than the DM
(Greitemeyer et al., 2001) but, over and above that, could reduce people’s motivation to commit
themselves to obtaining monetary amounts in Euros—for example, as a reward (cf. Ostaszewski et al.,
1998) or as a salary. Furthermore, in the area of consumer spending, the Euro could be perceived as
‘smaller’ (i.e. having less economic value), since it is a less valued object compared to the DM (in the
sense of the Bruner & Goodman, 1947 findings). Therefore, people might have the impression that
they can buy less with the Euro as compared to the strong and stable DM. Price estimations, in turn,
should be higher in Euros compared to DM.
In sum, in this overview we have outlined possible psychological changes in the perception and
estimation of prices and salaries caused by the introduction of the Euro. Whereas some of these
processes are triggered by the pure change in nominal values (money illusion, anchoring effect), others
are based on people’s attitudes towards the Euro (devaluation of the Euro if people hold a negative
attitude towards this currency). Interestingly, all these processes lead to the same prediction for
Germany. Whenever one of these processes is at work, we should expect people in Germany to
perceive the same real salary as being more attractive if it is given in DM than if it is given in Euros. Of
course, the same should be true for prices. The same real price should appear lower if it is given in
Euros than if it is given in DM. In turn, people should estimate higher real prices for the same product
if they make this estimation in Euros than if they make this estimation in DM.
To investigate whether or not these psychological effects of the Euro do in fact occur and, if so,
which of the processes outlined above is responsible for these effects, we ran five studies. In the first
two studies, we compared people’s perception of salaries (Study 1) and estimation of prices (Study 2)
in Euros versus DM. In Studies 3 to 5, each of the three processes outlined above (attitude-based
devaluation of the Euro, money illusion, anchoring effect) was tested as a possible explanation for the
effects found in Studies 1 and 2. All studies were carried out in Germany and were conducted between
the autumn of 1998 and the spring of 2001.
STUDY 1
Participants were asked to evaluate the attractiveness of job offers depending on the salary being paid
in DM or Euros. The study was based on the consideration that the present nominal value of a salary in
DM will be roughly divided in half after the introduction of the Euro. (An employee presently earning
80,000 DM a year will receive approximately 40,000 Euros as a salary after the introduction of the
Euro.) The real purchasing power, however, will not be changed by the monetary reform. On the other
hand, as we have outlined in the theoretical introduction, what could change is how people evaluate the
attractiveness of their own salary. More precisely, the prediction derived from our theoretical
considerations was that people would evaluate an annual salary in Euros as less attractive than the
corresponding amount in DM. However, we felt that simply letting people rate the attractiveness of a
given salary on a rating-scale might be a somewhat unreliable and imprecise measure of how attractive
this salary really appears to the participants. Thus, we used a more direct and behavioural indicator of2Among the 12 members of the European Monetary Union, Germany ranks second to last, just ahead of Finland with 45%supporters and 49% opponents, whereas Italy ranks first with 79% supporters and only 17% opponents.

attractiveness. The more attractive a salary is considered to be, the more employees are expected to be
willing to face difficulties in order to obtain the sought position. The time it takes to get to work is one
such impediment. Thus, we asked our participants what upper time limit they would be willing to
accept on commuting to work for a given salary. We assumed that their willingness to take longer
travelling times into account would be lower if their salaries were paid in Euros rather than in DM.
Method
Participants
One hundred and twenty students of an introductory psychology class (82 female, 38 male)
participated in this study. The age of the participants ranged between 18 and 64 years.
Design
The experiment is based on a 2 (currency: DM versus Euros)� 5 (salary range: 60,000 DM/30,000
Euros versus 76,000 DM/38,000 Euros versus 90,000 DM/45,000 Euros versus 100,000 DM/50,000
Euros versus 110,000 DM/55,000 Euros) factorial between-subjects design. Participants were ran-
domly assigned to experimental conditions.
Procedure
The study was conducted during one of the lectures. The participants received a short questionnaire on
which they were asked to imagine themselves having finished their university studies and being
presented with a job offer with a certain annual gross income. One half of the participants were made
offers with incomes given in DM, whereas the others were made offers that were specified in Euros.
The annual gross income varied between 60,000 DM and 110,000 DM, and between 30,000 Euros and
55,000 Euros, respectively. The participants had to indicate for which maximum amount of travelling
time (in minutes) for a one-way trip to their workplace they would be willing to accept the offer.
Results and Discussion
One participant who indicated that he would generally not take the offered job for 60,000 DM was
excluded from the analysis. Another participant was also excluded because she stated her willingness
to spend three hours one way to get to work, which exceeded three standard deviations from the mean
of M¼ 57 minutes. (In fact, this would mean that this person would spend six hours a day just to get to
her workplace and back home.) The means of time participants were willing to spend in order to get to
work (single trip) for each condition are displayed in Table 1. The ANOVA revealed two significant
main effects. First, the higher the offered salary was, the more time the participants were willing to
invest to get to work, F(4, 108)¼ 3.74, p< 0.01, �2¼ 0.12. For 60,000 DM/30,000 Euros they were
willing to accept a distance of M¼ 45.77 min (SD¼ 21.53), for 76,000 DM/38,000 Euros the
average distance was M¼ 50.20 min (SD¼ 19.97), for 90,000 DM/45,000 Euros it was M¼ 64.09
(SD¼ 30.42), for 100,000 DM/50,000 Euros it was M¼ 56.19 (SD¼ 22.69), and for 110,000 DM/
55,000 Euros the average accepted distance was M¼ 67.29 (SD¼ 21.16). This effect is, of course, not
surprising because it simply reflects a cost–benefit trade-off. However, it underlines that our
participants did take the experimental material seriously and made rational calculations, even though
their answers were purely hypothetical.
152 Eva Jonas et al.

More importantly, the main effect for currency was also significant, F(1, 108)¼ 7.97, p< 0.01,
�2¼ 0.07. For job offers figured in Euros, the willingness to invest time was significantly lower
(M¼ 50.09 min; SD¼ 22.13) than for the same job offers figured in DM (M¼ 62.21 min,
SD¼ 24.99).3 This result supports our prediction that the same real salary would appear less attractive
if it was given in Euros than if it was specified in DM. As outlined in the introduction, these differences
in the perception of salaries can be caused by different kinds of processes, some of which operate on
the simple change in nominal values (money illusion, anchoring effect), whereas others are based on
people’s attitudes towards the Euro—which are somewhat negative in Germany. However, prior to
differentiating between such underlying psychological processes, it seems necessary to confirm our
predictions with a different dependent measure, namely price estimation. Thus, in Study 2 we looked
at the area of consumption and asked participants to estimate appropriate prices for different consumer
goods either in Euros or in DM.
STUDY 2
This study was designed to examine whether and how the introduction of the Euro has an effect on
price estimation of various consumer goods. On this occasion, some participants were asked to
estimate the prices of products from a department store catalogue in Euros, whereas others had to
estimate prices in DM. As outlined above, our hypothesis was that people asked to estimate the
products’ prices in Euros would estimate higher prices than people who had to estimate prices in DM
because, due to either cognitive processes such as money illusion or anchoring or to an attitude-based
depreciation of the Euro, the same real amount of money (the same real prices) should appear lower if
specified in Euros than if specified in DM. Thus, prices in Euros should undergo a ‘surcharge’.
Method
Participants
Sixty adults (30 male and 30 female) with ages ranging from 18 to 67 participated in this study. The
participants were recruited in a public building in Munich and were asked to participate in a brief
experiment on ‘shopping’.

Design
The experiment is based on a one factorial between-subjects design with two experimental conditions
(currency: DM versus Euros). Participants were randomly assigned to experimental conditions.
Procedure
A catalogue containing illustrations of 11 different consumer goods (e.g. a CD player, a rubber dinghy)
was handed to the participants. These articles had been chosen from the catalogues of various mail
order firms. The real prices of the items covered a range from 200 to 800 DM. A picture of each
product was shown with prices and other descriptive details removed. The catalogue was given to each
participant individually. The participants were asked to look at each picture separately and then
spontaneously estimate an appropriate price for the corresponding product. The participants in the DM
condition had to give the prices in DM, those in the Euro condition gave them in Euros. In order to
avoid complicated currency conversions, the participants in the Euro condition were asked to use an
exchange rate of 2 DM to 1 Euro (instead of the real exchange rate of 1.96 DM to 1 Euro).
Results and Discussion
Three participants in the Euro condition were excluded from the analysis because they failed to follow
the instructions on the conversion rate. For a better comparison of the data in the experimental
conditions, the given Euro sums were multiplied by two, in accordance with the conversion rate used
by the participants, to arrive at the equivalent DM figures.4 The effect for the currency factor reached
significance, F(1, 55)¼ 5.06, p< 0.03, �2¼ 0.08. The corresponding means revealed that the average
price estimations for the consumer goods were lower in the DM condition (M¼ 349.24, SD¼ 86.03)
compared to the Euro condition (M¼ 418.54, SD¼ 142.77). Thus, the results show that estimating
prices in Euros leads to higher subjectively appropriate prices than estimating the same prices in DM.
This result is completely in line with our predictions derived from the theoretical introduction and
with the finding from Study 1, where the same real salary was considered as being less attractive if it
was given in Euros than if it was given in DM. The subjective value of the same amount of money was
lower if the currency was Euros than if this currency was DM. This, in turn, leads to higher price
estimations in Euros compared to DM. One important aspect of these findings is that both for the
context of salaries and for the context of consumption, the judgmental implications differed between a
situation given in Euros versus DM, although the rest of the situation is absolutely identical. Thus,
what we have found with regard to the Euro could be seen as an analogy to what is called the violation
of the ‘invariance axiom’ in the context of decision-making research (Tversky & Kahneman, 1988).
Just as alternative representations of the same situation should lead to the same choice, the same real
amounts of money given in different currencies should yield the same judgemental response.
However, drawing such conclusions is only justified to the extent that the two situations—apart
from the different currencies—are really identical for the participants; and there is at least one
possible alternative interpretation. Rather than reacting to the currency, the participants might have
reacted to the time frame activated by the currency. Studies 1 and 2 were conducted during the second
half of 1998. People who were asked to make price estimations or rate the attractiveness of salaries in
DM may have made their judgements with regard to the prevailing time frame, whereas people asked
4As the participants had been told in advance to use a currency rate of 2:1 (to avoid extensive mathematical calculations), thesame rate was used in the course of the calculation, and not the actual rate of 1.96:1.
154 Eva Jonas et al.

to give the same ratings in Euros may have made their judgements against the background of a future
time frame (i.e. for 2002, the year of introduction of the Euro). If this were the case, one would expect
higher price estimations in the latter than in the former condition due to price inflation. This effect,
however, would be unrelated to the currency Euro per se; it would simply reflect the activation of a
different time frame through this currency. To check for this possible alternative explanation, in
Study 3 we explicitly manipulated the time frame within which judgements are made. People are
asked to estimate prices either for 1999 or for 2002, and this factor is crossed with the currency factor.
If the time frame interpretation were true, then keeping the time frame constant should make the Euro
versus DM effect disappear. Instead, the anticipated effect of the time frame should be that higher
prices are estimated for 2002 than for 1999.
In the event that the difference in price estimations is not due to different time frames but rather to
the currency Euro itself, this effect could be explained by different processes. As we have outlined in
the introduction, some of these processes, namely the ‘money illusion’ and ‘anchoring’, operate on the
change in nominal values from DM to Euros, whereas others operate on the whole change of the
monetary system (negative attitude towards giving up the national currency for an international,
European monetary system; subsequent debasement of the new currency). In Study 3 we dealt with the
latter processes. Since in Germany people’s attitudes towards the Euro are much more negative than
their attitudes toward the DM, they are reluctant to give up the DM and to trade it in for the Euro
(Greitemeyer et al., 2001). People suspect that their economic future would fare better if they kept
their national currency (DM), and many expect prices to rise after the introduction of the Euro (Kiell &
Muller-Peters, 1999; Peters, presentation at the XXIst conference of the International Association for
Research in Economic Psychology (IAREP), Paris, 1996; van Everdingen & van Raaij, 1998).
Compared to the strong and stable DM, the Euro seems to be considered as a weak and insecure
currency. This negative attitude towards the Euro could have led our participants in Study 1 to perceive
a Euro salary as less attractive than one in DM and therefore intuitively show less motivation to
commit themselves to obtaining the Euro salary. When estimating consumer prices in Euros, simply
the mere mention of the Euro could raise people’s reservation towards this currency and intuitively
lead to higher price estimations in the Euro condition compared to the DM condition.
If this explanation were true, then we should expect the Euro versus DM effect to be stronger
among people with a more negative attitude towards the Euro. Thus, we decided to measure our
participants’ attitudes towards the Euro and the DM and to test whether or not these attitudes moderate
the differences in price estimations between Euros and DM.
STUDY 3
As outlined above, the goals of Study 3 were twofold. On the one hand, we wanted to examine the
possibility that different time frames associated with making price estimations in DM versus Euros
could be responsible for the effects found in the first two studies. Whereas making judgements in DM
could activate a current time frame, giving the same judgements in Euros could trigger a time frame
dating to 2002 when the Euro actually replaces the national currencies in everyday life. Thus, people
could make higher price estimations simply in order to factor in the inflation rate up until that year.
Therefore, in Study 3 the time frame was manipulated and thereby kept constant for each participant.
Whereas in one condition the participants were asked to estimate the consumer goods prices at the
time of the study (summer of 1999), in the other condition we asked participants to estimate the prices
for the point in time after the introduction of the Euro, namely 2002. If the time frame was responsible
for the Euro versus DM effect, this effect should disappear (because the time frame is constant in each

condition); instead, the time frame factor should lead to a main effect indicating that higher price
estimations are made for 2002 than for 1999.
On the other hand, we wanted to investigate whether people estimate higher prices in Euros than in
DM because they hold a more negative attitude towards the former compared to the latter currency
and, thus, debase the Euro. For this purpose, we asked participants whether they thought that the Euro
would personally bring them more advantages or disadvantages and whether they thought that
the Euro would lead to increasing prices. If the results from the former studies are caused by the
participants’ attitude towards the Euro, one should expect that especially those participants who are
very sceptical with regard to the introduction of the Euro would show a more biased price estimation
than those participants who hold a neutral attitude or are even in favour of the Euro and optimistic
about the time after the introduction of this currency.
Method
Participants
Forty adults (27 male and 13 female) with ages ranging between 21 to 45 years participated in this
study. They were recruited in a public building in Munich.
Design
The study was based on a 2 (currency: DM versus Euros)� 2 (time frame: today [1999] versus time of
introduction of the Euro [2002]) between subjects design. Participants were randomly assigned to
experimental conditions.
Procedure
The procedure was similar to Study 2. The participants were given the catalogue and were asked to
estimate the appropriate price of each product. Participants made these price estimations either in DM
or in Euros. In the condition ‘time frame: today (1999)’ the participants were asked to estimate the
prices for today. In the condition ‘time of introduction of the Euro (2002)’ participants were asked to
estimate the prices for that time.
Next, the participants gave ratings on their attitudes towards the Euro. They were asked whether
they thought that they personally would benefit or be disadvantaged by the Euro (on a scale between
1¼ benefit and 5¼ disadvantage, with a value of 3 indicating that the participant thought the Euro
would not lead to any changes at all). They were further asked whether they thought that, due to the
introduction of the Euro, prices would tend to rise or decrease through the Euro (on a scale between
1¼ rise and 5¼ decrease, with a value of 3 indicating that prices were expected to remain stable).
Results and Discussion
As in Study 2, we converted the prices in the Euro conditions to DM prices. Table 2 shows the means
of the average estimated prices. The ANOVA revealed a significant main effect of the currency factor
on price estimations, F(1, 36)¼ 4.38, p< 0.05, �2¼ 0.11. Significantly higher prices were assessed in
156 Eva Jonas et al.

the Euro conditions (M¼ 417.17, SD¼ 163.90) compared to the DM conditions (M¼ 328.02,
SD¼ 88.37). The main effect for time frame did not reach significance, F(1, 36)< 1. The means
were even somewhat in the opposite direction than predicted by the time frame hypothesis, as the
average price estimation for the 1999 time frame was M¼ 375.84 (SD¼ 109.75), whereas the mean
for the 2002 time frame was slightly lower (M¼ 369.35, SD¼ 163.68). Furthermore, the interaction of
both factors also did not reach significance, F(1, 36)< 1, indicating that the Euro versus DM effect was
not moderated by the time frame. Thus, we can rule out time frame effects as an alternative
explanation for the higher price estimations in Euros compared to DM.
We now turn to the two attitude measures and the question of whether the price estimation effects are
moderated by these measures. We tested this hypothesis with two different methods, namely one using
correlation measures and one using a post-hoc median-split. With regard to the first method, if the
‘attitude hypothesis’ were true, one would expect that price estimations in the Euro conditions are posi-
tively related to the question about personal advantages or disadvantages as a consequence of the Euro,
since high values on this item indicate that the person expects the disadvantages to dominate—and this, in
turn, should lead the person to devalue the Euro. However, this correlation did not reach significance
(r¼ � 0.21, p> 0.35) and even pointed in the opposite direction. For the second attitude-related
question, namely whether the person expects prices to rise or decrease as a consequence of the Euro
introduction (with higher values indicating an expectation that prices will decrease), one would expect a
significant negative correlation with price estimations in the Euro conditions. Although in this case the
empirical correlation pointed in the predicted direction (r¼ � 0.26), it was not significant (p> 0.25).5 In
sum, we found no correlational evidence for the hypothesis that a negative attitude towards the Euro is
responsible for the higher price estimations compared to the DM.6

5The intercorrelation of the two attitude items was too low to allow for an aggregation of both items into an overall attitudemeasure (r¼ � 0.16, p> 0.30). Furthermore, it should be noted that measures of the participants’ attitudes toward theEuro in our sample were neither clearly positive nor clearly negative. The mean for the question whether they wouldpersonally benefit from the Euro or not was M¼ 2.77 (SD¼ 1.24 on a scale from 1¼ benefit to 5¼ disadvantage. Thisvalue did not differ significantly from the scale midpoint of 3, t(38)¼ 1.16, p> 0.20. Regarding the question whether theEuro would rather lead to decreasing or to rising product prices, the mean wasM¼ 2.83, SD¼ 0.84 on a scale from 1¼ riseto 5¼decrease. This value also did not differ significantly from the scale midpoint of 3, t(39)¼ 1.31, p> 0.15.6Against this conclusion, one might object that the participants’ attitudes towards the Euro were measured with only two itemsand, therefore, insufficient reliability could be responsible for the lack of evidence with regard to the attitude hypothesis. Thus,we ran an additional small study (N¼ 15, 6 male and 9 female participants aged between 17 and 60) in which we measuredparticipants’ attitude towards both the Euro and the DM more extensively with 6 items for each currency. We asked theparticipants about the subjective attractiveness, stability, valence, security, calculability and likeability of each currency.These measures showed high reliability (DM scale �¼ 0.90, Euro scale �¼ 0.94). Participants exhibited a somewhat morepositive attitude towards the DM (M¼ 7.17) than to the Euro (M¼ 5.78), t(14)¼ 1.76, p¼ 0.10. However, there was nocorrelation with price estimations in Euros (for the attitude towards the Euro r¼ 0.08, p> 0.75, for the attitude towardsthe DM r¼ � 0.13, p> 0.65).
Psychological effects of the Euro 157

These results are confirmed by two additional 2� 2 ANOVAs, using post-hoc median-splits of both
attitude items each in addition to the currency factor ‘currency’. Both analyses revealed the effect for
currency, F(1, 35)¼ 4.21, p< 0.05, �2¼ 0.11 for advantages/disadvantages as second factor,
F(1, 36)¼ 3.72, p¼ 0.06, �2¼ 0.09 for price rise/decrease as second factor. Furthermore, in none of
these analyses the main effect of the median-split factor or, more importantly, the interaction of both
factors reached significance (all Fs< 1, all ps> 0.35). Participants showed about the same price
estimations in Euros, no matter whether they thought that they would personally benefit from the Euro
(M¼ 423.65) or not (M¼ 415.56), or whether they thought that due to the introduction of the Euro the
prices would tend to rise (M¼ 424.06) or decrease (M¼ 414.22). If the higher price estimations in
Euros compared to DM (and, in turn, the lower attractiveness of Euro compared to DM salaries) were
due to the fact that people in Germany hold a negative attitude towards the Euro, devalue the Euro and,
thus, value the same amount of money less if it is in Euro than if it is in DM, one should expect that the
differences in price estimation occur particularly among persons with a more negative attitude toward
the Euro, and less among persons with a more positive attitude towards this currency. However, the
results did not hint at such a moderation. Thus, both the correlational and the quasi-experimental data
analysis revealed converging evidence, leading to the conclusion that negative attitudes towards the
Euro are not responsible for the higher price estimations in Euros versus DM.
Study 3 revealed another replication of the Euro versus DM effect. However, the question of how
this effect is caused remains unanswered. One of the three mechanisms outlined in the theoretical
introduction, namely attitude-based devaluation of the Euro, was not supported in Study 3. Although
we must be aware that the statistical power of our samples was rather limited and therefore the attitude
explanation cannot be ruled out definitely, we will now turn to the two other candidates in order to
further investigate the effect. Both mechanisms are not related to the replacement of the monetary
system, but rather with the change in nominal values from DM to Euros. One of these candidates is the
‘money illusion’ (Fisher, 1928; Shafir et al., 1997). As outlined above, the money illusion describes the
effect that the perceived value of a particular amount of money in a given currency is positively
correlated with the magnitude of its figures since people tend to focus on the nominal values of notes
and coins and disregard the real value. As a consequence, 100 DM would appear more valuable than
(approximately) 50 Euros simply because ‘100’ is larger than ‘50’. Therefore, lower nominal figures
in one currency lead to the perception that a consumer good is cheaper whereas higher nominal figures
in another currency lead to the perception that the consumer good is more expensive, although the real
values might be identical in both cases (Shafir et al., 1997).7 As a consequence, people might perceive
a price of 400 DM as appropriate for a CD player, but they might find that 200 Euros is too cheap for
the same product.
The other possible explanation for psychological effects of the Euro based on its nominal value are
anchoring effects in price perception and price estimation (e.g. Northcraft & Neale, 1987). That is, if
people have relatively high salient standards of comparison when making price estimations, these
estimations deviate upwards (from the estimations of people without any standard of reference, i.e.
without any anchor), and when these salient standards are relatively low, the same estimations deviate
downwards. In our case, the critical feature leading to higher price estimations in Euros compared to
DM would be the fact that the familiar DM prices constitute anchors for the estimation of the new Euro
prices. Since the old prices are higher than the new ones, higher price estimations are the consequence.
In Studies 4 and 5, we attempted to test these two competing explanations.
7Obviously, one would expect the money illusion effect to work only within certain boundaries. For example, it does not seemplausible that the extreme magnitude of the figures of the Italian Lira lead to a proportional increase in the perception of thevalue.

STUDY 4
How can the money illusion hypothesis be tested against the anchoring hypothesis? One conclusion to
be drawn from the money illusion hypothesis is that the effect observed in comparing price estimations
in Euros versus DM should not be specific for the Euro but instead should occur for other currencies as
well if the conversion rate leads to lower nominal figures compared to the DM. On the other hand, an
opposite phenomenon to the Euro versus DM effect should occur with currencies that incorporate
higher nominal figures than the DM. Since in this case the same real amount of money leads to higher
nominal figures compared to the DM, identical real prices should appear higher if they are given in this
currency than if they are given in DM. Lower price estimations compared to the DM should be the
consequence.
Thus, in Study 4, in addition to Euros and DM, two further currencies were introduced: the
British Pound and Austrian Schilling. These two currencies were chosen because one of them
(Austrian Schilling; exchange rate¼ 7 Schilling for 1 DM) is characterised by higher, the other
(British Pound; exchange rate ¼ 0.35 British Pound for 1 DM) by lower nominal values compared
to the DM. If our results can be explained by the phenomenon of the money illusion, the participants
estimating prices in British Pounds should exhibit the same effect as participants in the Euro
condition. Since, for example, a CD player for £140 should appear cheaper than the same player for
400 DM, participants in the British Pound condition should estimate higher prices than participants
in the DM condition. Strictly stated, the effect should be even larger in the British Pound condition
since the exchange rate of about £0.35 to 1 DM leads to even smaller nominal figures than the
conversion rate of about 0.50 Euro to 1 DM. On the other hand, participants estimating prices in
Austrian Schillings are confronted with larger numbers. Therefore, they should make adjustments in
the opposite direction and thereby arrive at lower price estimations than participants in the DM
condition.
In contrast to the money illusion, anchoring effects should be unaffected by the manipulations in the
latter two conditions. More specifically, we would not expect any anchoring effects to occur in these
conditions. The reason for this prediction is that making price estimations in British Pounds or
Austrian Schillings intuitively triggers a cognitive set of shopping in a foreign country. In German
shops, with which the participants are familiar, products are not designated in British Pounds or
Austrian Schillings. Thus, the well-known DM prices do not seem applicable to this setting. Since it
was demonstrated that the strength of anchoring effects depends on the applicability of the anchoring
information to the judgemental context (Strack & Mussweiler, 1997), we can assume that we should
find no (or, at least, smaller) anchoring effects for British Pounds or Austrian Schillings. In contrast,
when these price estimations are made in Euros, the salient frame of reference for the participants is
‘shopping at home’ because the Euro is considered as their own currency. In this situation, the familiar
prices that the participants have learned in exactly this context interfere and constitute anchors for the
estimation of new Euro prices.

Psychological effects of the Euro 159

Design and Procedure
The study was based on a one-factorial between subjects design with four experimental conditions: the
DM and Euro conditions were created in analogy to Study 2. In the ‘British Pound’ condition, prices
had to be estimated in British Pounds (at a conversion rate of £0.35 to 1 DM) and in the ‘Schilling’
conditions in Austrian Schillings (at a rate of 7 OS to 1 DM). There were 15 participants in each
condition. As in Studies 2 and 3, the participants were given the catalogue and were asked to estimate
the appropriate price of each product.
Results and Discussion
As in Studies 2 and 3, we converted all prices into DM. Table 3 shows the means of the average
estimated prices for each condition. The factor ‘currency’, once again, had an effect on price
estimations, F(3, 56)¼ 3.27, p< 0.03, �2¼ 0.15. Post-hoc tests (LSD method) showed that signifi-
cantly higher prices were assessed in the Euro condition (M¼ 433.44, SD¼ 95.11) compared to the
DM (M¼ 329.95, SD¼ 67.90), Pound (M¼ 346.26, SD¼ 135.90), and Schilling (M¼ 338.22,
SD¼ 101.81) conditions, all ps< 0.03, with the latter three conditions not differing significantly
from each other, all ps> 0.65. Obviously, the money illusion hypothesis that the perceived value of a
given amount of money is positively correlated with the magnitude of the price figure could not be
confirmed. Neither did the participants make higher price estimations in British Pounds, nor did they
estimate lower prices in Austrian Schillings, both compared to the DM condition. We also did not find
any hint that estimating prices in a foreign currency generally leads to a surcharge intended to make
people feel ‘on the safe side’. Thus, a lack of familiarity with a certain currency cannot explain the
results either.
However, as suggested by the anchoring hypothesis, there is a specific effect of the Euro currency.
Only in the case of price estimations in Euros, on average, were higher prices estimated compared to
DM. As suggested above, we assume that the specific effect of the Euro is caused by the fact that only
those anchors influence a judgement that are applicable to the object of judgement (Mussweiler,
Forster, & Strack, 1997, Study 3; Strack & Mussweiler, 1997, Study 1). We assume that for those
participants who estimated prices in Euros, the mental frame of their own country and their own shops
was activated since the Euro is going to replace the former national currency soon and had already
been, in fact, introduced into the economy in 1999. Thus, when people estimate prices in Euros, they
should have the same mental frame (shopping at home) as people who make price estimations in DM.
If these people are confronted with pictures of particular products, salient images should be activated
in which the products are combined with pricing labels in the familiar and well-known DM currency;
and these salient DM prices could serve as anchors in the process of making price estimations in Euros.

The situation in the case of estimating prices in British Pounds or Austrian Schillings is quite
different. British Pounds and Austrian Schillings are clearly foreign currencies, which will never
become a trade denomination for Germany (at least the participants do not expect this to happen).
Therefore, a different mental frame, namely shopping in a foreign country, should be activated, and
prices in DM should not appear applicable to this frame. In sum, the results of Study 4 are in line with
the anchoring hypothesis. However, Study 4 does not provide unequivocal evidence for the correctness
of the anchoring hypothesis since we only excluded the money illusion mechanism as an explanation
for our results. Therefore, in Study 5 we aimed to examine the anchoring hypothesis more directly.
STUDY 5
One possibility to directly test the anchoring hypothesis is to remove (or at least reduce) the
applicability of the familiar prices in DM as an anchor when estimating prices in Euros. If the DM
prices no longer seem applicable as an anchor, price estimations in Euros should no longer be different
from price estimations in DM. In order to implement this, in Study 5 we manipulated the participants’
mental frame, namely by asking them to imagine a shop in their home country (Germany) versus a
shop in a foreign country. In the latter case, we asked participants to estimate prices in Euros versus
DM for shops in Ireland. In such a situation, the familiar DM prices should not serve as an anchor since
the anchoring information for the domestic prices is not applicable for price estimations in Ireland.
In Study 5 we thus crossed the factor currency (DM versus Euros) with the factor ‘mental frame’
(familiar [Germany] versus unfamiliar [Ireland]). As outlined above, if the anchoring hypothesis is
correct we should replicate the difference between DM and Euros only in the case of a familiar mental
frame (Germany). In the case of Ireland as a mental frame, the familiar DM prices should not
constitute anchors and, thus, no difference between the Euro and DM conditions should occur.
Method
Participants
Eighty adults (38 male and 42 female) with ages ranging from 18 to 62 years participated in this study.
They were recruited in a public building in Munich.
Design
The study was based on a 2 (currency: DM versus Euros)� 2 (mental frame: familiar [Germany]
versus unfamiliar [Ireland]) between-subjects design. Participants were randomly assigned to experi-
mental conditions; there were 20 participants per condition.
Procedure
As in Studies 2 to 4, the participants were given the catalogue and were asked to estimate the
appropriate price of each product. Participants estimated the prices either in DM or in Euro. The
condition ‘mental frame: Germany’ was identical to the previous studies. In the condition ‘mental

frame: Ireland’, participants were asked to imagine estimating the prices for shops in Ireland. To make
the two conditions comparable, it was emphasised that the price level in Ireland was about the same as
in Germany.
Results and Discussion
As in the previous studies, all prices were converted to DM. Once again, the main effect for currency
was significant, F(1, 76)¼ 6.34, p< 0.02, �2¼ 0.08. Significantly higher prices were assessed in the
Euro conditions (M¼ 425.54, SD¼ 156.30) compared to the DM conditions (M¼ 347.33,
SD¼ 127.30). The main effect for mental frame did not reach significance, F(1, 76)¼ 1.10,
p> 0.25, �2¼ 0.01. However, in accordance with the anchoring hypothesis, the main effect for
currency was qualified by a significant interaction with mental frame, F(1, 76)¼ 5.02, p< 0.03,
�2¼ 0.06. Simple effect analyses showed that only with the familiar frame (Germany) price
estimations in Euros were significantly higher (M¼ 476.59, SD¼ 186.05) than price estimations in
DM (M¼ 328.80, SD¼ 77.89), t(76)¼ 3.36, p< 0.002. In the unfamiliar frame ‘Ireland’, the
difference disappeared (Euro: M¼ 374.50, SD¼ 100.21; DM: M¼ 365.86, SD¼ 162.70),
jtð76Þj<1, p> 0.80. This interaction effect is illustrated in Figure 1.
Further post-hoc analyses between the four conditions (LSD method) revealed that significantly
higher prices were assessed in the ‘Euro–Germany’ condition compared to all other three conditions
(‘DM–Germany’, ‘Euro–Ireland’, ‘DM–Ireland’), all ps< 0.05), with the latter three conditions not
differing significantly from each other (all ps> 0.30). Thus, the unfamiliar frame ‘shopping in Ireland’
did not heighten the participants’ price estimations in DM but rather lowered their price estimations in
Euros.
The results of Study 5 clearly support the anchoring hypothesis. If we induce an unfamiliar mental
frame when the participants estimate prices in Euros—the image of Irish shops that, according to the
anchoring hypothesis, should not fulfil the condition of applicability for using familiar DM prices as
anchors—the effect of different price estimates in Euros versus DM disappeared, whereas for the

The Euro versus DM effect disappears if price estimations are made within an unfamiliar frame ofreference, namely estimations for shops in Ireland (instead of Germany).

familiar frame (Germany) we replicated the central finding from the studies above, namely that the
price estimates in Euros were significantly higher than those in DM. Thus, Study 5 reveals strong
indications that the difference between perceiving the same amount of money in Euros versus in DM is
caused by the difference in numerical values and that, furthermore, the nominal values of the former
familiar currency interfere with the perception of the new currency. Only if the applicability of the
former familiar currency is blocked by introducing an unfamiliar mental frame, the DM versus Euro
effect disappears.
GENERAL DISCUSSION
The trigger for the research reported here was the consideration of the possible psychological effects of
the forthcoming currency reform introducing the Euro. The starting point of our studies was the
question of whether and in what respects the introduction of the Euro would influence people’s
perception of money. We raised the question of whether it makes a psychological difference for people
to confront the new Euro as compared to their former national currency given that the real value of the
money remains about the same. In our studies, we concentrated on two specific and important aspects
of money perception, namely the attractiveness of particular salaries and the estimation of prices for
consumer goods. Three hypothetical processes, namely the money illusion, anchoring effects and an
attitude-based devaluation of the Euro were outlined. In the case of Germany, all these processes led to
the same prediction, namely that the same real amount of money would appear lower if it was given in
Euros than if it was given in DM. In turn, we predicted that identical real salaries would be less
attractive in Euros than in DM, and higher prices for consumer goods would be estimated if these
estimations were made in Euros compared to DM.
The results of our first two studies confirmed these predictions and indeed showed that it makes a
difference whether an otherwise identical situation is given in Euros or DM. When wages were
specified in Euros, people showed less willingness to accept difficulties associated with a job offer
compared to wages given in DM. When asked for their estimation of appropriate prices for various
consumer goods, people made higher estimations in Euros than in DM.
As Study 3 clarified, these different judgements in the Euro versus DM conditions did not result
from different time frames being activated by these currencies. Because people making judgements
with regard to DM could frame the situation as ‘current’ (1999, the time when the study was
conducted), whereas judgements in Euros could activate a future time frame (2002 or later), people
could have simply factored in the expected inflation rates up to that time. However, this was not
the case. Furthermore, Study 3 revealed that, although participants in general held a more negative
attitude towards the Euro than towards the DM, these attitudes were not associated with price
estimations. Thus, we could not support the attitude-based devaluation hypothesis. In Study 4,
we found out that the effects mentioned above only occurred in connection with the Euro and not with
the conversion into other foreign currencies. When converting prices to British Pounds or Austrian
Schillings, no difference in price estimation compared to the DM resulted. Thus, we demonstrated that
in case of the conversion to the Euro, a different kind of phenomenon was involved than that which is
familiar to many holiday-makers in foreign countries and which psychologists call the ‘money
illusion’, indicating that the perceived value of a currency is positively correlated with the magnitude
of its figures (Shafir et al., 1997). If money illusion had been the underlying mechanism for the Euro
versus DM effect, one should also have expected higher price estimations in British Pounds, whereas
in Austrian Schillings price estimations should have been lower than in the DM condition. None of
these effects occurred.
Psychological effects of the Euro 163
Copyright # 2002 John Wiley & Sons, Ltd. Eur. J. Soc. Psychol. 32, 147–169 (2002)
Finally, in Study 5 we successfully demonstrated that the differences between the DM and Euro
conditions in the former studies were due to anchoring effects: When people make judgements in
Euros, then ‘normally’ this judgement activates a familiar mental frame—in the case of price
estimations, this frame might be called ‘shopping in one’s hometown’. Within this mental frame, the
salient DM prices with which one is familiar and which are closely connected to the corresponding
products constitute anchors for the price estimation process in Euros. Since the anchor values lie above
the corresponding Euro prices, higher price estimations are the consequence. If, however, an
unfamiliar mental frame is explicitly triggered, as in the ‘foreign country’ conditions of Study 5
where people were asked to make price estimations for shops in Ireland, the DM price anchors are no
longer applicable to the judgement task and, thus, are not activated and no longer influence the
judgements (cf. Mussweiler et al., 1997, Study 3; Strack & Mussweiler, 1997, Study 1). Thus, in sum
our studies highlight that anchoring effects could bias price estimations and the perception of salaries
after the introduction of the Euro in 2002.
In What Way Do Salient DM Price Anchors Bias Price Estimations in Euros?
These considerations lead to the question of how the mechanism underlying the anchoring effect of the
salient DM reference prices on price estimations in Euros works. Obviously, our studies were not
designed to allow for such a detailed micro-level analysis of cognitive processes mediating these
anchoring effects. The current state of research on anchoring (cf. Mussweiler & Strack, 1999, 2001;
Strack & Mussweiler, 1997) implies that the following process is involved: According to Mussweiler
and Strack (2000a,b), who refer to the general framework of Wyer (1973), categorical judgements
about a specific feature of an object (as, for example, the age of a particular person or, as in our case,
the price of a particular product) can be conceptualised as ‘the expected value of the distribution of
probabilities that the target belongs to each of the given scale categories’ (Mussweiler & Strack,
2000a, p. 496). Thus, people have a plausible range of prices for a given product in mind (for a
particular CD player, for example, this could be a range from 200 DM to 1000 DM), and they use their
knowledge to assign probabilities to each of the cases within this range (i.e. that this CD player will
cost 200 DM, 300 DM, 400 DM etc.). This, of course, is hardly ever conducted as a completely
conscious rational calculation, but rather as a more or less implicit inference. If an anchor within this
range is salient (such anchors are called ‘plausible anchors’, cf. Mussweiler & Strack, 2001), this
anchor leads to selective accessibility of knowledge implying that the target’s extension on the
category scale is roughly equal to this value (Mussweiler & Strack, 1999; Strack & Mussweiler,
1997).8 If in our CD player example an anchor of 300 DM is salient for a person, this person
predominantly generates knowledge about why the CD player could be so cheap. This, in turn, lowers
the person’s price estimation compared to a person without a salient anchor. The opposite happens in
the case of high anchor values. In addition, if the anchor value lies outside the plausible range of the
distribution (e.g. a numerical value of 15 DM), this mechanism is supplemented by ‘insufficient
adjustment’: In this case, people first adjust to the boundary value of the plausible price range (which
would be 200 DM in our example) and then test whether or not the price could be equal to this
boundary value (selective accessibility). Again, relatively low price estimations would be the
consequence.
8This suggests that the anchoring effect of DM prices only applies to those consumer goods for which a range of plausible valuesactually exists (cf. Mussweiler & Strack, 2000a). In the absence of such a range, as is, for example, the case for cigarette prices,we would not expect an anchoring effect to occur when prices in Euros are estimated. However, whether this is actually the caseis an open question for further empirical research.

These processes can be used to explain in what way anchoring effects might bias price estimations
in the Euro conditions. According to the view stated above, the participants have to convert their
distribution of plausible prices from DM into Euros. However, when they calculate the final Euro
prices for the products, the familiar DM prices—which lie within the upper part of this distribution or
even outside the plausible range—selectively make knowledge accessible that implies why these
products should be expensive. As a consequence, the participants estimate relatively high prices for
these products.
For the same mechanism to be able to account for the findings of Study 1, namely that people were
willing to accept more difficulties for the same real salary if it was given in DM than if it was given in
Euros, one would have to assume that for each level of difficulties (i.e. staggered increases in distance
between home and workplace), a probability distribution exists in which each salary is assigned a
probability denoting that the particular salary is an appropriate compensation for a certain level of
difficulties.9 As a response to the questionnaire item, a specific level of difficulty (i.e. a specific
distance between one’s home and one’s workplace) is chosen for which the expected value of the
particular probability distribution equals the salary offered to the participants. Due to the nominally
high reference salaries in DM, selective knowledge is generated that supports the hypothesis that a
high Euro salary is necessary to compensate for given difficulties. Because this effect works within
each single probability distribution, the subjective expected values of the distributions are artificially
heightened, which, in turn, leads to a lower level of difficulties being chosen by the participant.
However, the mechanism underlying the anchoring effects in our studies could also be a simpler
one. In the case of price estimations, people might start by making a first price estimation in DM.
The process of reaching this price estimation might be similar to the one described above (subjective
expected value of the distribution of probable prices), or the estimate might also be a more
spontaneous guess. In the DM conditions, the price estimation process has now been completed. In
the Euro conditions, participants convert this price estimation (and not the distribution) into Euros.
However, because the nominally higher DM prices are salient, the Euro price seems to be unusually
low. The participants can hardly associate the particular products with such low nominal figures. An
upward adjustment could be the consequence. In the case of salary attractiveness, the salient higher
nominal DM salaries could also make the Euro salary appear unusually low, thus implicitly decreasing
the participants’ willingness to accept long distances between home and workplace for this salary.
In the sense of the definition of anchoring as ‘the assimilation of a judgement to a salient standard of
comparison’ (Mussweiler & Strack, 2000b, p. 1038), such processes would also constitute anchoring
effects. However, they would not fit any of the two popular explanations for these effects, namely
‘selective accessibility’ and ‘insufficient adjustment’. Note that although we also spoke of ‘adjust-
ment’ in the price estimation example, this adjustment would be quite different from the one known
from the literature. Whereas ‘insufficient adjustment’ means that people start from an anchor and fail
to sufficiently adjust from the anchor towards the real value (Jacowitz & Kahneman, 1995), in our
case they would start from the real value and, due to the salience of an anchor, would be misled to
adjust their estimation towards that anchor. It could be an interesting question for further research to
clarify whether the more elaborate process from the Mussweiler and Strack (1999) model or the more
9Note that in the more simple case of people using an ‘acceptability distribution’ of different difficulties (different distancesbetween home and workplace) for a given salary—which would fit the question format more closely—and judge their accepteddifficulty as the expected value of this distribution, this approach could not explain the anchoring effect of the DM salaries.Because here the scale format is distance instead of money, the DM anchors are not applicable to this scale. In this case, the onlyway to save this explanation would be to assume that the salient DM salaries are connected with salient acceptable distances. Ifpeople are offered a salary of, for example, 60,000 Euros, the immediate reference salary is 60,000 DM. Since people aresomehow reluctant to accept large distances between workplace and home for 60,000 DM per year, these relatively lowacceptable distances would constitute the actual anchors in this judgement task and lead to relatively low estimations in the Euroconditions.
Psychological effects of the Euro 165

intuitive and spontaneous process described above, which we might also call a ‘contrast effect’
between Euro stimulus and DM anchor, lies at the heart of the biasing effect of DM reference values on
the perception of Euro values.
Implications and Directions for Further Research
Although we only investigated effects of the Euro on the perception of money in Germany, this does
not mean that the results necessarily can only be applied to Germany. For the citizens of other
countries joining the European monetary union, the former national currencies should also provide
anchors when perceiving prices and salaries in the new currency. With regard to these other countries,
the anchoring hypothesis even allows specific predictions to be made. Since in most countries that
participate in monetary union the conversion rate leads to smaller nominal figures in Euros compared
to their former national currency, people in these countries should exhibit the same anchoring effects
as our participants in Germany. For example, for France where the conversion rate is about 1 Euro to
6.6 French Francs, price estimations in Euros could even be exaggerated in comparison to our German
Euro conditions since the French are used to even higher nominal values. For Ireland, the opposite
effect can be assumed. Since the Irish are used to smaller numbers in their national currency
(Irish Pound) compared to the Euro, the corresponding anchoring effect should work in the opposite
direction. For people in those countries which will not be joining the monetary union at this point in
time (such as, for example, Britain), no anchoring effects should occur at all since their psycho-
logical situation should be identical to those participants in Study 5 for whom an unfamiliar mental
frame was activated: Because they do not consider the Euro as being their home currency, no
mental frame of shopping in their hometown should be triggered and, thus, no salient reference prices
in their national currency should constitute anchors for price estimations. Each of these predictions
could be easily tested and would provide further information about the appropriateness of the
anchoring explanation.
A test of this hypothesis in Italy would be of particular interest. Since the conversion rate of the
Italian Lira to the Euro is 1 Euro to 1940 Italian Lira, the Italians are familiar with nominal prices that
are extraordinarily higher than the ones in Euros. In terms of the Mussweiler and Strack (1999, 2000a,
2001) framework, the reference prices in Lira would constitute implausible anchors (they clearly lie
outside the boundaries of the distribution of plausible Euro prices); and these implausible anchors
have, in general, been shown to lead to even stronger anchoring effects than plausible anchors
(Mussweiler & Strack, 2001). According to these authors, this can be explained by postulating that
implausible anchors affect judgements by a combined strategy of selective accessibility and
insufficient adjustment, whereas plausible anchors only trigger the former mechanism. Thus,
according to this view we would expect particularly strong anchor effects among participants in Italy.
If, however, the anchoring effects of the national currency on price estimations in Euros are more or
less based on what we called a ‘contrast effect’, namely that the salient prices in the national currency
let the Euro price estimations appear unusually low and, thus, lead to an adjustment towards these
anchors, then due to the large discrepancy between the former (Lira) and the new (Euro) values we
would hardly expect that the Euro price estimations are compared to these former prices in Lira—
thus, no anchoring effects should occur. First preliminary data from a small study gave us some hints
that the latter may be the case: Whereas in a German sample the well-known Euro versus DM effect
was evident and in a British sample, as predicted, no differences in price estimations between the
British Pound and the Euro occurred, the Italian sample also showed no signs of anchoring effects.
However, before such results can be interpreted, they have to be substantiated with the use of larger
and more representative samples than the small convenience samples we used in this pilot study.

A second implication for further research that can be derived from our studies is to test how quickly
and to what extent anchoring effects of the old national currency disappear if people become more
familiar with dealing with the new currency. From January 2002 onwards when the new Euro coins
and notes enter circulation, people’s experience with the use of this currency will increase. Once
people have built up cognitive representations of typical prices in Euros, we should expect the
anchoring influence of the prices in the former familiar currency to disappear. A closely related
topic of interest is whether young people become accustomed to the Euro more quickly than older
people do. Since the older people have collected more experience with prices in DM, their cognitive
representations of consumer goods and prices should be connected more closely to the DM than those
of younger people.
Finally, we would like to emphasise that, although we did not find an association between people’s
attitudes towards the Euro and their price estimations, we do not think that the symbolic value of the
Euro and the national currencies should be neglected. On the contrary, we agree with the notion of
Burgoyne et al. (1999) that people’s reactions to the Euro probably will be very complex and that the
introduction of the Euro goes far beyond any everyday economic change. For example, even if the
perception of prices in Euros is not influenced by people’s attitude towards this currency, the actual
willingness to make payments and to spend the money probably is. Observations during the
introduction of the 1 Pound coin in Britain as well as the Dollar coin in the United States support
the prediction that behaviour towards money is affected by the money’s physical characteristics
(Webley, Lea, & Hussein, presentation at the 8th International Symposium on Economic Psychology,
Bologna, 1983). In Britain people showed strong negative reactions towards the 1 Pound coin and tried
to get rid of it as soon as they could. In the United States the Dollar coin even had to be withdrawn 1
year after its introduction because it was rejected by the public (Webley et al., 1983).
In sum, our research gives reason to doubt the assumption that the introduction of the new
banknotes and coins in the course of the monetary union in Europe has little more meaning than to
substitute one currency, as one medium of exchange, for another. As our results indicate, the
introduction of the new Euro banknotes and coins will probably cause some confusion and irritation
among the population. Consumer prices might seem unusually low possibly enticing persons to spend
more money than they actually intended. On the other hand, the amount of money people have at hand
seems to be diminished which might induce them to undertake special precautions when spending
money. Whether these effects will cancel each other out, or whether one of them will dominate and,
thereby, affect people’s consumption behaviour in general, remains an open question for further
research.
