The Link between Insurance and Banking Sectors: An International Cross-Section Analysis of Life Insurance
Demand*
Benjamin Lorent† This version, Augustus 2010
Abstract
Life insurance has become an increasingly important part of the financial sector. The past ten
years have witnessed significant changes of the market conditions faced by the insurance industry.
Two trends are especially crucial: the assimilation of banking-sector type activities by life insurers
and the consolidation of financial services (e.g. bancassurance). This article identifies the factors
determining consumption for life insurance products across 90 countries for the year 2005. We
introduce new factors to account for the increased link between bank and insurance sectors.
Using a larger dataset, our results confirm the existing literature by showing that countries with
higher income, better developed financial system, better educated population and higher old ratio
spend more money on life insurance products whereas life expectancy tends to decrease life
insurance demand. Moreover, institutional, religious and legal factors are found to be important.
The levels of inflation and interest rates, the young ratio and the size of the social security system
appear to have no robust association with life insurance consumption. The set of new variables
introduced: bancassurance and banking efficiency appear significant, with a negative impact on
life insurance consumption. Restricting our sample to developed countries confirm previous
results for banking efficiency and bancassurance. The results highlight that the increasing blurring
of the boundaries between insurers and banks impact life insurance demand.

1. Introduction The insurance sector has dramatically changed over the last twenty years. The time when
companies used to sell only classical insurance contracts is over. Life insurers have turned into
savings vehicles and play an increasingly role in the financial markets. The growing importance of
life insurance as a provider of financial services and of investment funds in capital markets is
especially pronounced in developed countries.
Life insurance policies offer two main services: income replacement for premature death and
savings instruments. They provide mortality coverage only, known as term policies, or they
combine mortality coverage with a savings component. The second category, known as whole life,
universal life, variable life…typically earn interest, which is returned to the policyholders trough
capital on maturation of the policy, policy dividends… Life insurers also sell annuity policies.
Initially, life insurance business was different from savings. Nowadays, with the increasing savings
type insurance, the situation has changed. Henceforth, savings type insurance products are
marketed on the basis of their investment characteristics: return and/or liquidity. The importance
of savings products is particularly noteworthy because this is the market where insurers face the
most vigorous competition from banks, mutual funds and investment advisory firms.
Due to demographic changes ahead the social security of most developed countries are under
increasing pressures. Many countries already face (or forecast very soon) the need for pension
reforms since the actual systems are insufficient to provide future generations the promised
benefits. Because many programs have been based on pay-as-you-go financing schemes, the
decrease in the ratio of working age to retired people has been forcing many countries to consider
scaling back their public pension systems, leading to their full or partial privatization. It provides
an opportunity for financial firms to exploit the growing demand for supplemental retirement
programs funded by life insurance and annuities and should provide growth opportunities for life
insurers in many markets.
The increasing blurring of the boundaries between insurers and banks is another trend faced by
the life insurance industry. Financial companies are now interconnected in a way without
historical precedent: bancassurance, assurfinance, cross-shareholding… Bancassurance is the
provision of insurance services by banks (assurfinance/allfinanz is the opposite trend, the
provision of banking services by insurers). In many countries, banking networks represent the
leading distribution channel for life insurance products as well as non-life products. The
3
development of bancassurance is uneven around the world. It is highly developed in Europe,
especially in the South (France, Benelux and Spain). By contrast, the phenomenon is relatively
limited in Germany or in the United Kingdom. Bancassurance model is more recent in the US
because of prior legislative restrictions.
The consumption of life insurance differs greatly between industrial countries (from 1,408.6 $ per
capita in 19991 to 2,174.4 $ in 2008) and emerging countries (from 23.4 $ per capita in 1999 to
39.2 $ in 2008) leading to a huge unexploited market in developing countries. The large disparity
in the use of life insurance across countries raises questions about what causes this variation. This
has attracted considerable attention in investigating key factors influencing the demand for life
insurance. Main literature contributions are Dickinson and Khajuria (1986), Truett and Truett
(1990), Browne and Kim (1993), Outreville (1996), Ward and Zurbruegg (2002), Beck and Webb
(2003) and Li et al. (2007).
This study’s contribution resides in a new effort to understand what drives the life insurance
consumption within a sample of 90 countries2 for the period 2005. This study is then limited in
depth but not in breadth. The determinants of life insurance consumption can be expressed by an
equilibrium demand-and-supply model. Although many studies have identified determinants of
life insurance demand, little is known about factors affecting the supply of life insurance products,
especially the insurance price, the link between banking and insurance sectors and the regulation
of financial companies.
Most empirical studies include the financial development of a country as a potential determinant
of life insurance consumption but do not measure the real competition between banks and life
insurers. Then we improve on the existing literature in several ways. First, we introduce new
variables reflecting the increasing link and competition between banking and insurance sectors,
enhancing the savings characteristic of life insurance policies. These variables measure the
convergence between banks and insurers as bancassurance, but also the increased competition
between financial companies as banking profitability and efficiency or banking regulation.
Additionally, savings life insurance may induce economic factors to better explain life insurance
demand. In particular, inflation, interest rates might influence the consumption of life insurance

products. This paper is the first after Beck and Webb (2003) that study life insurance
determinants taking into account the savings role of life insurance products.
Besides the introduction of new variables, we use a new dataset that extends the coverage of
economies: 90 countries spread throughout the world. The choice of countries included within
the sample is mainly based on the availability of life insurance premium data. To our best
knowledge, Beck and Webb (2003) is the widest study including 68 economies. We split our
sample in two: developed and developing countries. The samples are mutually exclusive. Viewing
insurance as personal financial planning is more popular in developed countries than in the
developing world. We expect then different results regarding financial and economic variables
and factors linking banking and insurance sectors.
The results are expected to help policymakers identifies the supply and demand factors for life
insurance products. They might particularly help developing countries in their fostering of life
insurance markets. The rest of the paper is structured as follows. Section 2 provides a description
of the factors explaining life insurance consumption, including new variables introduced in this
study. Section 3 depicts the model and methodology used in our empirical model. Section 4
presents and analyzes the main results. A conclusion and further research are then presented in
the final section.
2. Determinants of Life Insurance Consumption Empirical tests have been conducted to measure the significance of factors determining life
insurance consumption. Principal work includes that of Browne and Kim (1993) and Outreville
(1996), whose findings show that the level of life insurance consumption within an economy can
be explained by the GPD, the price of insurance, the inflation, the dependency ratio and the
financial development. Browne and Kim’s study is based on 48 countries, throughout the world,
for two separate time periods (1980 and 1987). Based on a cross-sectional analysis of 48
developing countries, Outreville (1996) analyzed the demand for life insurance for the period
1986. Ward and Zurbruegg (2002) investigated the determinants of consumption in Asia (22
countries). They compared their panel with OECD countries. Analyzing the data from 1987
through 1998, they found evidence that improved civil rights and political stability leads to an
increase in the consumption of life insurance in the Asian countries as well as in OECD region.
Using a panel with data aggregated at different frequencies for 68 economies in 1961 - 2000, Beck
and Webb (2003) showed that economic indicators such as inflation, income per capita, banking
5
sector development and religious and institutional indicators are the most robust predictors of the
use of life insurance. They drew their conclusions using the division of life insurance
consumption into the savings, mortality risk and annuity components. Li et al (2007) examined
the determinants of life insurance consumption in OECD countries. They found that life
insurance demand increases with the income, the number of dependents and level of education,
and decreases with life expectancy and social security expenditure.
In this paper we will focus on the link between banks and insurers. Therefore besides the basic
set of economic, social and institutional variables used in previous studies, are also incorporated
into the possible explanatory factors that affect life insurance density3: banking sector efficiency,
profitability and solvability, banking regulation and bancassurance indicators. For expository
purposes, each of the factors contained within the final estimation model are explained in depth
below.
2.1 Social Factor
Social security expenditures measure the average welfare as a percentage of GDP. Social security
systems generally provide a basic protection level for income termination in the event of the
death of a wage earner. Lewis (1989) postulated that social security displaces private insurance. As
government increases its social expenditures, the need for individuals to protect themselves
against longetivity and early death decreases. This is particularly accurate for life insurance
products with a mortality component or annuities. Moreover, as social security is financed by
taxes, high social expenditures can reduce individual income and consequently life insurance
purchase. Browne and Kim (1993), Ward and Zurbruegg (2002) and Beck and Webb (2003)
showed that the need for life insurance purchase is reduced when government spending on social
security is increased. We use the ratio health expenditure to GDP as a proxy for social security
expenditures. We expect a negative relationship between social security variable and life insurance
demand, especially in developed countries.
3 Life insurance density is defined as life premiums per capita. Using premium income as a proxy of life insurance
may become inappropriate because premiums represent total revenues that are equal to price times output (Cummins
et al. 1999). Indeed, differences in the price of products across countries and across insurance companies may give
rise to misleading inferences about life insurance expenditures across countries. Unfortunately due to the lack of data
regarding insurance price, we use this proxy.
6
2.2 Economic Factors
All works related to life insurance consumption have shown a positive relation between income
level and life insurance consumption (see e.g. Fortune, 1973; Lewis, 1989; Browne and Kim, 1993;
Outreville, 1996). A person’s consumption and human capital increase along with income
creating a greater demand for insurance to safeguard the income potential of the insured and the
expected consumption of his or her dependents. In addition, as income increases, life insurance
becomes more affordable. Finally, increasing income may encourage individuals to diversify their
investments and direct a part of their income to savings products. It is therefore hypothesized
that the disposal personal income measured by GDP per capita is positively related to life
insurance expenditures.
We expect that a higher inflation rate will be negatively correlated with life insurance density.
Because life insurance products typically provide monetary benefits over a long-term, monetary
uncertainty has a substantial negative effect on the expected return of life insurance products. As
the present value of assets is calculating by discounting future cash-flows (the sums to be received
in the insurance contract), the benefits from purchasing life insurance decrease. Babbel (1981),
Browne and Kim (1993), Outreville (1996), Ward and Zurbruegg (2002) and Beck and Webb
(2003) have shown that inflationary expectations have a significant negative impact on life
insurance consumption.
A higher real interest rate increases life insurers’ investment returns and thus their profitability, in
turn offering greater profitability of financial relative to real investment for potential purchasers
of life insurance policies. This is particularly accurate for life savings instruments. Moreover
higher real interest rates increase the supply of capital and therefore the ability of life insurance
companies to answer to potential demand. On the other, higher interest rates may induce
consumers to reduce their life insurance purchases given the anticipation of higher returns.
Indeed, as life insurance products compete with other financial products, a higher real interest
rate may divert investment flows from insurance products to banking products. Therefore we do
not have any expectations regarding the sign of the relationship between life insurance premiums
and real interest rates. Outreville (1996) found an insignificant relationship between real interest
rates and life insurance demand. Browne and Kim (1993) and Ward and Zurbruegg (2002)
neglected this variable. Beck and Webb (2003) and Li et al (2007) found significant influence of
this variable, but with a contradictory sign.
7
Insurance price is undoubtedly an important determinant of the consumption of life insurance.
Measuring the impact of price is, however, difficult due to the problem of actually determining
the price. The previous literature used life expectancy as a proxy for insurance prices (Outreville,
1996; Ward and Zurbruegg, 2002; Hwang and Greenford, 2005). Unfortunately using life
expectancy as a proxy for insurance price exhibits a number of problems (Ward and Zurbruegg,
2002). The price or the policy loading charge can be approximated by the ratio of total
expenditures on life insurance premium to the amount of life premium (Browne and Kim, 1993).
This ratio can be interpreted as the cost per dollar of life insurance coverage. Unfortunately, data
are relatively limited. Leaving out the price may subject the empirical testing to omitted variable
bias. Beck and Webb (2003) assumed that the price is a function of several supply-side factors
such as urbanization, monetary stability, institutional development, political stability and banking
sector development. All these factors affect the insurer’s ability to provide cost effective
insurance. In line with Beck and Webb (2003), we assume that insurance price is approximated by
supply factors, in this study by institutional development, political stability, financial development
and efficiency, profitability and regulation of banks. Indeed, banks and insurers are
complementary but they also compete each other as they offer similar products.
2.3 Financial Development and Banking Factors Outreville (1996), Ward and Zurbruegg (2002), Beck and Webb (2003) and Li et al (2007) showed
that life insurance development is significantly related to the country’s level of financial
development. The financial development can be an important source of growth in the insurance
industry. This might due to the fact that well functioning banks may increase the confidence of
consumers in other financial institutions. A more developed banking sector can also increase
competition with other financial sectors, especially insurance companies. This assertion is
particularly appropriate for banking-type products, i.e. savings instruments, offered by life
insurers. Ward and Zurbruegg (2002) used the variable private credit from banks and other
financial institutions over GDP as a proxy of financial development4. Private credit measures the
amount of savings that is channelled through debt-issuing financial intermediaries to private
borrowers. They showed a significantly positive link between financial development and life
insurance penetration in their two sub-samples (OECD countries and Asian countries). But the
effect is higher in developed countries. It would imply that the importance of the financial
4 The financial development can be measured in different ways. Outreville (1996) and Li et al (2007) used the (M1 –
M2)/M2 ratio in their empirical study. Beck and Webb (2003) introduced the banking development variable, defined
as total claims of deposit money banks on domestic non financial sector as a share of GDP.
8
intermediary sector is to complement insurance consumption in developed countries. In the
Asian countries where financial institution development is not as important the impact is not as
great. According to Levine et al. (2000), private credit is the best variable to measure financial
development. Private credit is more than the financial sector size as it includes an efficiency side
in its measure. Consequently we use this variable to measure financial development.
This study aims to go one step further and better gauge the banking sector efficiency. As
insurance and banking sectors are increasingly intricated, especially in the life business, the
banking efficiency and profitability may have an impact on life insurance supply, therefore on life
insurance consumption. A higher efficiency provides to banks new capital, fostering the offer of
savings instruments and the competition with insurers. Competition usually results in higher
quality products and lower prices for insurance policies, increasing life insurance consumption.
More efficient banks can also offer better returns to savers. But if the insurance sector is not able
to respond to the decreasing prices, the banking sector might gain market shares decreasing life
insurance demand. Therefore, we do not predict any sign for the relationship between banking
efficiency and life insurance consumption. The banking efficiency may be measured by the
following variables: net risk margin5, bank income cost ratio and overhead cost6. We also test the
efficiency hypothesis by using profitability variables: return on assets (ROA), return on equity
(ROE) and bank-z-score7. Finally we test our model for the variable bank concentration8 which is
defined as the ratio of the three largest banks assets to total banking sector assets. A highly
concentrated banking sector may result in lack of competitive pressure to attract savings which in
turn may decrease the competition with insurers and finally increase insurance prices. On the
other, a highly concentrated banking sector might lead to higher bank products’ price. We expect
then an ambiguous relationship between bank concentration and life insurance density.
There is no data or direct measure of insurance regulation. We therefore proxy some aspects of
insurance supervision using bank regulation variables. In many countries, the banking supervision
is linked to the insurance regulation. Sometimes, the same institution controls both activities. In
other countries, the control is organized jointly. In both cases, sound and vibrant practices in the 5 Defined as the accounting value of a bank’s net interest revenue as a share of its total assets 6 Defined as the accounting value of a bank’s overhead costs as a share of its total assets 7 Defined as a model to predict bankruptcies (see appendix 2 for further information). The higher the number the
lower the risk. 8 This indicator is based on bank-level data. Since the bank coverage is not 100%, variation across countries might be
driven by difference in coverage rather than difference in market structure.
9
banking control may trigger same experiences in the insurance sector. As extensively studied in
the literature, the banking sector analysis allows us to make some assumptions regarding the
insurance sector. A regulated banking sector might foster higher confidence into the industry,
increasing confidence into the insurance sector as well. On the other, overregulated sector may
prevent or restrict companies to launch new activities, decreasing the competition with insurers.
We expect then an ambiguous relationship between bank regulation and life insurance demand.
As a measure of bank regulation, we identify three variables in the dataset provided by Barth et al.
(2004): bank activity regulatory, competition regulatory, and official supervisory power. Bank
activity regulatory’s variable measures the degree to which national regulatory authorities allow
banks to engage in other activities than traditional one: security, insurance and real estate activities.
The empirical evidence indicates that restricting bank activities has negative repercussions with
lower banking-sector efficiency (Barth et al., 2001; Barth et al., 2004). Considering the ambiguous
relationship between banking efficiency and life insurance demand, we do not expect any
relationship sign.
We extract from this dataset the variable bancassurance which measure the degree to which
national regulatory authorities allow banks to engage in insurance activities. The aim is to perceive
if bancassurance companies increase the visibility and accessibility of life insurance products,
fostering life insurance consumption. Bancassurance may allow banks to exploit economies of
scale and scope and thereby provide services more efficiently. On the other, companies selling
one mix of products (bank vs. insurance products) may be more specialized and efficient in their
role. Therefore mixed companies may have negative impacts on life insurance consumption
instead of fostering it. In addition, such complex companies cannot be effectively monitored due
to informational asymmetries and opacity. Finally, both the market and political power enjoyed
by such companies can impede competition and adversely influence policies. So we do not have
any expectation regarding the sign of the relationship between the bancassurance variable and life
insurance consumption. We stress that this variable proxies a possibility offered to companies
and not an obligation. If a country allows banks to engage in insurance activities, it is not clear
that companies will use that possibility.
Competition regulatory variable measures the specific legal requirements for obtaining a license to
operate as a bank. Some argue that effective screening of bank entry can promote stability.
Others stress the beneficial effects of competition and the harmful effect of restricting entry. We
expect an ambiguous relationship between this variable and the life insurance demand.
10
Official Supervisory power measures the extent to which official supervisory authorities have the
authority to take specific actions to prevent and correct problems. Some theoretical models stress
the advantages of granting broad powers to supervisors (due to informational asymmetries,
difficulty to monitor banks...). On the other hand, powerful supervisors may exert a negative
influence on banks’ performance. They may use their powers to benefit favoured-constituents,
attract campaign donations and extract bribes. Therefore we expect an ambiguous relationship
with life insurance consumption.
2.4 Demographic Factors
The degree of risk aversion in a country may be related to the predominant religion. Zelizer (1979)
noted that religion historically has provided a strong source of cultural opposition to life
insurance. Religion may also shape national view regarding property rights, competition, taxation
and the role of the state. Browne and Kim (1993), Outreville (1996), Ward and Zurbruegg (2002)
and Beck and Webb (2003) included in their set of variables a religious proxy. Browne and Kim
(1993) showed that predominantly Islamic countries consume less life insurance than non-Islamic
countries. In some Muslim-dominated countries, there are possible legal or political conditions
that may hamper life insurance growth. Followers of Islam have traditionally disapproved life
insurance consumption because it is considered a hedge against Allah9. Beck and Webb (2003)
went further and incorporated a broader measure of religious inclination by including
Protestantism, Catholicism and a composite of other religions, defined as the ratio of the
adherents of a religion to the entire population. We use the same approach in this paper. While
we expect a negative relationship between Muslim population and life insurance consumption, we
do not have any prior expectations regarding the sign of relationship with other religions.
One of the main purposes of life insurance is to protect dependents against financial troubles,
following the premature death of the household earner. In line with previous literature, the
average number of dependents per potential life insurance consumer in a country is approximated
by the young dependency ratio10. As this ratio grows, it is more likely that income-earners will
purchase life insurance in the event of a premature death. Beenstock et al. (1986), Truett and
Truett (1990) and Browne and Kim (1993) found a significant and positive relationship.
The old dependency ratio, defined as the ratio of old dependents to the working age population
has been introduced by Beck and Webb (2003). It is expected to decrease the demand for the 9 Takaful is an exception, but not widely developed. 10 Defined as the number of young dependents over the total working population.
11
mortality risk component and increase the demand for the savings and annuity components of
life insurance products. We expect then an ambiguous overall effect of the old dependency ratio.
Life insurance consumption is hypothesized to increase with the wage earner’s probability of
death (Lewis, 1989). Considering that life expectancy is inversely related to the probability of
death, we predict a negative relationship between life expectancy and life insurance consumption.
On the other, as argued by Outreville (1996), longer life expectancy may decrease the price of life
insurance and therefore tends to stimulate its consumption. Moreover, countries with a longer life
expectancy should increase demand for products with an annuity component. Earlier studies have
found contradictory conclusions: Beenstock et al. (1986), Outreville (1996) and Ward and
Zurbruegg (2002) found a positive significant relationship whereas Beck and Webb (2003) and Li
et al. (2007) showed negative impact of life expectancy on life insurance demand.
Life insurance consumption should rise with education for several reasons. First of all, as showed
by Browne and Kim (1993), education is a good proxy to measure the risk aversion. An
individual’s education level is positively related to greater risk aversion. Secondly, a higher level of
education may increase the ability of people to understand the benefits and complexity of risk
management and long-term savings considering the social security financing issue. Finally, a
higher educated population is generally associated with higher salaries and then the need to
protect higher income. Browne and Kim (1993), Outreville (1996), Ward and Zurbruegg (2002),
Beck and Webb (2003) and Li et al. (2007) found a positive relationship between life insurance
consumption and the level of education. The average years of schooling in the population over
age 25 is used as a proxy for the level of education11.
2.5 Institutional and Legal Factors
A stable political and legal system is important for a vibrant and growing life insurance market.
Lack of political stability may prevent the construction of a long term relationship between the
customer and the life insurance company. The same argument is true for a weak legal system.
Levine (1997, 1998) showed that a good investor protection will induce a higher economic
11 We mainly use two different databases: Cohen and Soto (2007) and Barro and Lee (2001). The former is our main
data source. The average years of schooling is built by multiplying the population’s shares of educational attainment
by the appropriate length (in years) of each educational category. Cohen and Soto (2007) computed data until 2000
and made a projection for 2010. We used both values to extrapolate the data level in 2005. As Barro and Lee (2001)
computed data until 2000, we made projections for the period 2005. For Estonia, Latvia and Lithuania we use data
provided by Monga (2004).
12
growth. This situation is particularly applicable to life insurance products where relationship with
companies tends to be long term. Moreover, with the increasing complexity of life insurance
products, policyholder can suffer from informational asymmetry. The absence of sound legal
system may also hamper the efficiency of insurers’ investment, decreasing the profitability and
finally increasing the insurance price. Clearly then, the functioning of a working legal system and
the protection it may afford to policyholders is a major determinant of insurance market
penetration. Ward and Zurbruegg (2002) examined the impact of legal and political determinants
on life insurance consumption within Asian and OECD countries. They highlight that in Asia an
improvement in the legal system has a significant and positive impact on life insurance demand.
In order to capture the potential instability of political system, we consider the variable checks12.
It measures checks and balances within a country’s political system which is the number of
individuals with a veto within the political apparatus. This variable has been introduced by Ward
and Zurbruegg (2002). Number of checks should enhance the political efficiency; therefore we
expect a positive relationship between this variable and life insurance demand. Another set of
variables used for the measure of sound and stable political institutions is the indicators built by
Kaufman et al. (2008). They developed indices that measure various aspects of governance. They
constructed aggregating indicators of six dimensions13 for a sample of 212 countries. We expect
also a positive relationship between this set of variables and life insurance consumption. Beck and
Webb (2003) found a positive significant relationship between these six indicators and life
insurance demand.
Finally, we introduce the index of property right, provided by the Heritage Foundation (2008),
which measures the property right protection. This index is defined as an assessment of the
ability of individuals to accumulate private property, secured by clear laws that are fully enforced
by the state. With improvements of the index of property rights in a given country we would
12 As a substitute for checks, we introduce the variable legislative competition which is an index of the degree of
competitiveness of the last legislative election, ranging from 1 to 7. A greater competition will limit the ability of the
elite to dictate policy and institutional development. As the variable checks, we predict a positive relationship with
life insurance demand. 13 Voice and accountability, political stability, government effectiveness, regulatory quality, rule of law and control of
corruption, see appendix 2 for definition of all variables. The data reflects the views on governance of public sector,
private sector and NGO experts, as well as thousand of citizens. The indicators are based on several hundred
individual variables measuring perceptions of governance, drawn from 35 separate data sources constructed by 32
different organizations around the world.
13
expect the protection and enforcement of property rights to facilitate the transaction of insurance
policies. An ability to appeal the breach of life insurance contracts by insurers reduces the value
of such contracts to consumers and may deter them from committing large sums of money to
these products. Therefore, it is hypothesized a positive relationship with life insurance
consumption.

3. Methodology and Data The baseline model examines the relationship between main hypothesized factors and life
insurance consumption. In our model, we use log-linear form introduced by Outreville (1996)
and Browne and Kim (1993) for some variables. The log linear specification is frequently used
for estimating demand models. This creates linearity in the model and also provides for the
estimation of elasticities. To determine which variable should be specified in log form, the Box-
Cox procedure is employed.
Given the hypotheses specified above, the following baseline model is proposed:
Log(PREM)i = αi + β1log(GDP)i + β2log(EDUC)i + β3log(PRIVATECREDIT)i +
β4log(YOUNG)i + β5(INFL)i + β6log(OLD)i + β7log(LIFEEXP)i + β8(INT)i + β9log(HEALTH)i
+ εi
Here, the subscript i represents the country, αi are cross-sectional intercept terms, β1,…, β9 are the
slope parameters, and εi are random error terms.
PREM = demand for life insurance (per capita in constant US dollars)
GDP = income (GDP per capita in constant US dollars)
EDUC = education level (average years of schooling)
PRIVATECREDIT = measure of the financial development (average of previous 5 years16)
YOUNG = young dependency ratio
INFL = anticipated inflation (average of previous 7 years)
OLD = old dependency ratio
LIFEEXP = life expectancy at birth
HEALTH = health expenditure (as a percentage of GDP)
INT = real interest rates
Subsequent regressions include a larger set of potential determinants of life insurance
consumption, including economic factors, banking efficiency and regulation variables and
institutional and legal factors. 16 We averaged some data over five years because several of our explanatory variables are subject to short-term
fluctuations related to the business cycle and/or political events: PRIVATECREDIT, banking efficiency variables
and institutional and legal factors.
15
We use cross-section data for 90 countries17 in 2005. A cross-country comparison allow us
studying socioeconomic variables that change slowly over time, such as life expectancy, old or
young ratios, which go undetected in time series analyses. The year 2005 was chosen mainly for
two reasons. First of all some data are not available after 2005. Secondly data for banking
regulation including bancassurance have been collected in 200318. To take the effects of potential
regulation system reforms into account, we estimate that a two-year period is reasonable.
Data for life insurance premiums are obtained from Swiss Reinsurance Company, the African
Insurance Organization19 and the Association of Latin America Insurance Regulators20 and are
expressed in constant US dollars per capita. Life insurance consumption is represented by
premium income (PREM), which is equal to the price of insurance times the amount of insurance
sold.
The choice of the countries included in the sample was based on the availability of data,
especially life insurance premiums. The sample is split in two: developing and developed
countries 21 . Viewing insurance as personal financial planning is more popular in developed
countries than developing countries. We expect then different results regarding factors linking
banking and insurance sectors or some financial and economic factors. This distinction avoids
mixing different country characteristics and heterogeneous consumer demand. Moreover, it
allows to compare variables elasticities of demand for life insurance in the different samples.
Tables 2 and 3 present the summary statistics for the basic regression variables22. Demand for life
insurance exhibits a large dispersion across full sample countries. One quarter of the sample
presents a demand less than 7 $, whereas the higher quartile presents a demand higher than 589 $.
As we can see, there is a large variation in the economic and financial variables. On the other
hand, sociodemographic and social characteristics are seen to be more similar across the full
sample.
It is noticeable that the level of insurance life premium is higher in the developed countries. This
is not surprising given the higher GDP per capita and the higher financial development. In 17 See appendix 1, for the list of countries included in the sample. 18 Banking regulation database (Bart et al., 2004) is only available for the periods 2003 and 2007. 19 Burkina Faso, Côte d’Ivoire, Cameroon, Ethiopia, Gabon, Malawi, Senegal, Tanzania, Togo, Uganda and Zambia. 20 Guatemala and Honduras. 21 Distinction is based on World Bank classification (see appendix 1). 22 See appendix 3 for the summary statistics of the other variables.
16
addition, education, political and institutional factors, all thought to promote insurance
consumption, are more favourable in developed countries. Life insurance consumption in the full
sample represents a substantial portion of per capita income, with an average of 4.27 percent
corresponding to purchase per capita of 595.45 $ over an income of 13,928 $. Life insurance
density in developed countries represents 4.44 percent of income per capita, while this percentage
appears to be very low in developing countries with an average of 0.62 percent.

Many of the potential determinants of life insurance consumption are highly correlated with one
another (see table 4). Richer countries have older populations, longer life expectancies, higher
levels of schooling and better developed financial systems. The simple correlation coefficients of
all variables with life insurance density exhibit the expected sign, with the exception of HEALTH.
Life insurance consumption is higher for countries in which governments spend more money on
health expenditure. Life insurance expenditures appear to be negatively correlated with the young
dependency ratio. One problem associated with the variable YOUNG is that it rather proxies the
young adult population than the number of dependents.
The high correlations between the explanatory variables underscore the importance of
performing multivariate regression analysis. Including correlated variables will increase the risk of
generating estimates with high standard errors due the high level of collinearity. As the number of
observations is higher in this analysis compared to previous studies, this multicollinearity issue
would be partly alleviated.

4. Empirical Results
The first set of regression includes the basic subset of social and economic variables which can
lead to a comparison of the results from previous research by, for example, Browne and Kim
(1993) or Beck and Webb (2003).
The results show that the variation of life insurance density across countries varies with the GDP
per capita, the average years of schooling, the private credit ratio, the old dependency ratio and
the life expectancy. These five variables show significant coefficients in our baseline regression.
The estimated coefficients have the expected sign and are statistically significant to the 1, 5 or 10
per cent level. Since for several of our variables logarithmic values have been taken, the estimated
coefficients are measures of elasticity. Any value greater than 1 indicates that a change in that
variable will drive an even bigger change in the level of life insurance consumption. More
specifically, an increase in income of 10 per cent will increase the consumption of life insurance
by 11.5 per cent. The results are consistent with the models of Browne and Kim (1993),
Outreville (1996), Beck Webb (2003) or Li et al (2007).

The negative sign for the life expectancy supports the negative effect associated with the lower
probability of the income earner’s premature death. The county’s level of financial development
appears to be a strong determinant of its life insurance consumption. It implies that the
importance of the financial sector is to complement insurance consumption. The insurance sector
will benefit from a strong financial industry. Contrary to most previous models, inflation rate, real
interest rate, health expenditures and young dependency ratio cannot explain the variation in life
insurance density across countries. Replacing the inflation rate with the expected inflation rate
which is the average of the inflation rate in the current and the following year confirms the results.
The aim of this study was to better measure the link between banks and life insurers through their
increased competition and convergence. Table 6 presents results with banking variables as
dependent variables. In the first columns (1 to 4) we use banking efficiency and profitability
variables as potential determinants of life insurance consumption.
The bank concentration (CONC) is negatively related to life insurance consumption consistent
with the view that a higher concentrated banking sector decrease competition with the insurance
sector. Profitability (ROA) and efficiency variables (COST 23 ) are positively related to life
insurance density. Higher level of cost indicates lower efficiency. Therefore the overall effect of
banking efficiency and profitability is ambiguous. However from variables measuring the bank
efficiency, only bank-z-score factor enters significantly in our model. Bank-z-score is an indicator
of banking stability including a profitability component24. If profits are assumed to follow a
normal distribution, it can be shown that the bank-z-score is the inverse of the probability of
insolvency (see Boyd, Graham and Hewitt, 1993 or De Nicolo, 2000). A higher bank-z-score
indicates that the bank is more stable. The negative relationship with life insurance demand could
reflect either a measure of customers’ confidence in the banking system or a mixing effect of
profitability and customers’ confidence. A higher confidence might encourage savers to invest in
banking products instead of life insurance products. Secondly, as bank-z-score includes a
profitability measure, a higher score may allow banks to offer better returns than life insurance
products and at a lower price increasing banking products attraction and decreasing life insurance
consumption. This negative relationship shows that banking industry has an influence on life
23 As an alternative measure, we also tested net risk margin, bank overhead and ROE. With the exception of a
negative relationship between ROE and life insurance demand, the results were the same. 24 Bank-z-score = (ROA + equity/assets)/σ(ROA)

insurance consumption, especially via savings insurance. Moreover, including bank-z-score
increases the impact of economic factors, GDP and PRIVATECREDIT.

As a measure of banking regulation, we identify four variables (columns 5 to 8): competition
regulatory (REGCOM), bank activities regulatory (REGACT), bancassurance (BANC), and
official supervisory power (REGOFF). Our results are based on a panel of 78 countries25 as data
for other countries are missing.
Bancassurance variable is significant and has a positive sign. It means that countries where the
banking regulator restricts the ability of banks to engage in insurance underwriting and selling
25 See appendix 1 for details regarding countries included in this sample
Part II – An International Cross-Section Analysis of Life Insurance Demand 21
display a higher life insurance demand. This result shows that life insurance consumption
increases as banks are restricted to sell insurance policies. The reason may arise from the
specialization effect of life insurance business. An insurance company, as opposed to a
bancassurance company or a bank selling directly insurance policies may have a deeper
knowledge of the life insurance market and can better offer and sell life insurance products.
REGOFF 26 is negatively and significantly related to life insurance density. The explanation might
be threefold. Firstly, as some theoretical models stress the advantages of granting broad powers
to supervisors, the banking efficiency may be increased. On the other hand, powerful supervisors
may exert a negative influence on banks’ performances. As we find a negative relationship
between banking efficiency and life insurance demand, the first effect may be preferred. Finally,
as banking and insurance regulation are increasingly related, banking regulation practices may
influence the insurance sector as well. Therefore, a powerful supervisor in the insurance sector
may exert a negative influence on insurers’ performances.
In order to understand the role of the political stability and the legal system in promoting life
insurance consumption, the third group of results augments the earlier specification with political,
institutional and legal variables (see table 7). We use checks (CHECKS)27 as a measure of the
political environment and Kaufman’s indicators (voice and accountability (VA), political stability
(Pol_stab), government efficiency (Gov_eff), regulatory quality (Reg_qual), rule of law (ROL) and
control of corruption28 (Corr)) as a measure of institutional environment (columns 1 to 7). Both
political and institutional variables improve the quality of the model. CHECKS and VA enter
significantly at the 5 percent level in the regression. The overall results do show evidence to
support the hypothesis that political and institutional factors are determinants of life insurance
consumption in economies. This is clearly important to policymakers and new entrants, especially
in developing countries, as it highlights that these variables are key structural determinants of
future expansion. The index of property right has a significant and positive effect on the
consumption of life insurance. A sound legal environment is essential, considering the long-term
and complex aspect of life insurance products.
26 As an alternative measure, we use the variable supervisory forbearance discretion which measures the ability of
supervisory authorities to engage in forbearance when confronted with violation of laws and regulations or other
imprudent behaviours. This variable did not enter significantly in the regression. 27 As an alternative, we use the legislative competition. It did not enter significantly into our model. 28 As an alternative, we use the index of Free of Corruption. The results were identical.

Consistent with previous studies, the percentage of Muslim population explains the variation in
life insurance consumption across countries at a 5 per cent level. The results suggest that life
insurance consumption is less in predominantly Islamic countries. Other religions do not have

Table 9 presents results from cross-country regressions in the sub-samples. For each variable it
gives results for two baselines, one for the developed countries sample and one for the
developing countries. We remark that the developed model explains better life insurance
consumption than the developing model.
As expected, life insurance density in developed countries increases with income per capita,
private credit and decreases with life expectation. The old ratio and the education level do not
appear as significant variables anymore. This result is not surprising as both variables appear
more stable in developed countries. With the exception of the health expenditure in developed
countries and the inflation rate in developing countries, the estimated coefficients have the
expected signs. Restricting our sample to developing countries confirms the results for education
level, development of the financial sector and old ratio but not for GDP per capita and life
expectation.

With higher estimated coefficients, the impact of the income and the financial sector
development are of greater importance for insurance consumption in developed countries, as
opposed to developing countries. The former result might be surprising as previous studies (e.g.
Ward and Zurbruegg, 2002) pointed the “S curve” relationship between income and life
insurance consumption. The theory contends that the consumption of life insurance rapidly
accelerates as an economy begins to develop. At higher levels of income, insurance consumption
becomes less sensitive to income difference. However, in developed countries, the increase of
income creates a greater demand for insurance to safeguard the income potential of the insured
and the expected consumption of his or her dependents. Moreover as life insurance is a luxury
good, income per capita in developing countries may not be sufficient to allow customers to
afford life insurance products. Finally, prices may play an important role in the life insurance
demand. Higher prices relative to the income per capita in developing countries could explain the
lower impact of income per capita.
Part II – An International Cross-Section Analysis of Life Insurance Demand 25
In developed countries, a 10 per cent improvement in financial development
(PRIVATECREDIT) will lead to approximately a 10 per cent increase in life insurance
consumption. In developing countries, the improvement in consumption would be around 9 per
cent. This is an interesting result as it would imply that the importance of the financial sector to
complement life insurance consumption is more important in developed countries. However, in
developing countries, PRIVATECREDIT turns out to be one of the key determinants of life
insurance consumption. In particular, the impact is more important than GDP per capita. A well-
functioning financial system increases the visibility and the competition between financial
companies, leading to a higher confidence of consumers in life insurers. In developing countries,
the level of infrastructure, especially the financial system, is far less developed and stable than
wealthier countries. This result shows that demand factor, i.e. income per capita, is less decisive
than supply factor, i.e. financial sector development. The conclusion is inverted in developed
countries; the income is more elastic than the financial development. The results are
contradictory to Ward and Zurbruegg (2002) conclusions.
Life insurance density decreases with a higher life expectancy only in developed countries.
Regarding developing sample, Outreville (1996) found a positive and significant sign between life
expectancy and life insurance demand in a sample of 48 developing countries. The author used
the actuarially fair price of life insurance as a proxy for life expectancy at birth. He postulates that
a long life span decreases the price for insurance. Our results contradict this theory and support
the Lewis’ hypothesis (1989).
Turning to our additional explanatory variables (see table 10), the level of institutional
development, measured by voice and accountability (VA) and regulatory quality (Reg_qual),
explain life insurance demand only in developing countries. This is not surprising considering the
relatively high level of institutional factors in developed countries. This is clearly important to
policymakers and new entrants to the developing markets, as it highlights the institutional
environment as a key structural determinant of future expansion in these markets. Factors
affecting life insurance supply are again more significant in developing countries compared to
wealthier economies.
In the developed sample, economic variables seem to play a higher significant role in life
insurance sales than legal or institutional factors. The results confirm our previous conclusions
for bank_z_score and BANC variables. The convergence between insurers and banks, e.g.
bancassurance is particularly important in developed countries. Together with a significant
Part II – An International Cross-Section Analysis of Life Insurance Demand 26
bank_z_score, the results show that the increased competition with banks impacts life insurance
consumption in developing countries. This is consistent with the view of insurance policies being
savings instruments only in wealthier countries.

5. Conclusion
The past ten years have witnessed significant changes of the market conditions faced by the
insurance sector. Two trends are especially crucial: the assimilation of banking-sector type
activities by life insurers and the consolidation of financial services (bancassurance or
assurfinance/allfinance). These trends might have an impact on the key determinants of life
Part II – An International Cross-Section Analysis of Life Insurance Demand 27
insurance consumption. This article examines the determinants of life insurance consumption by
using cross-section analysis. We estimate the determinants in a panel of 90 countries in 2005.
Besides variables used by previous research, we introduce new factors reflecting the increasing
link between bank and insurance sectors. Using a larger dataset that has been previously
examined and consistent with previous research, the cross-country estimations show that
countries with higher income, better developed financial system, better educated population and
higher old ratio spent more money on life insurance products. A higher life expectancy decreases
life insurance density, supporting the model developed by Lewis (1989). The young dependency
ratio, expected inflation rate, real interest rate and health expenditures have no strong association
with life insurance density. In addition, religious and institutional differences can explain some of
the variation in life insurance consumption across countries.
From new variables introduced in this study, bancassurance and banking efficiency measured by
the bank-z-score turn out to be significant. The result is particularly interesting for the
bancassurance variable as the relationship sign is negative. It means that the more a banking
regulator restricts banks to engage in insurance underwriting and selling the more customers buy
life insurance policies. Similarly, bank efficiency and solvability measured by the bank-z-score is
negatively related to life insurance demand. The increased competition and convergence between
financial industries has a negative impact on life insurance consumption.
Splitting our sample into developed and developing countries shows that well-developed financial
sector continue to predict higher life insurance consumption across countries. Moreover, the
results suggest that the older the population and higher the education level, the more people in
developing countries will consume life insurance products. In developed countries, the life
expectancy decreases the life insurance density confirming the Lewis’s hypothesis. More telling is
the difference in the income and financial development elasticities between developed economies
and the developing countries. The impact of the income per capita and the financial sector
development are of greater importance in developed economies.
The results confirm our previous conclusions for banking efficiency and solvability and
bancassurance in developed countries. This is not surprising as the link between bank and
insurers is far more developed in the wealthiest countries. In developing countries, there is
evidence that high level of governance stimulates life insurance consumption. This result,
Part II – An International Cross-Section Analysis of Life Insurance Demand 28
together with a stronger effect of financial development compared to the income per capita,
show that supply factors play a beneficial role in determining life insurance density.
The results matter for policymakers to understand determinants of life insurance consumption,
especially in developing countries. Taking into account the impact of insurance development on
economic growth (Ward and Zurbruegg, 2000), these results provide strong insights for fostering
life insurance business.
Most of the studied determinants of life insurance consumption regard demand factors. More
research needs to be done on the supply side, especially the insurance price and insurance
regulation factors. Investigation of the effect of the life insurance concentration could also lead to
further understanding of life insurance consumption. A highly concentrated insurance sector may
result in lack of competitive pressure which in turn may increase insurance prices. On the other
hand, bigger insurance groups may be able to spread the fixed costs of operating over a broader
customer base thus is likely to offer lower prices.
