Abstract Using household survey data on Nepal, the paper examines income disparities by 13 regions and 12 ethnic, language and caste (ELC) groups that are identified as building blocks for a federal Nepal in Acharya (2007). Results show that there are massive between-region (across regions) and between-ELC group inequalities. The within-region (across individuals in the same region) and within-ELC group disparities are even wider. The inequalities are so alarming that to bring Nepal in par with one of the countries in the Nordic region (Denmark, Finland, Norway and Sweden), the 20% richest people in Nepal should pay additional taxes of 46% from their income. This will raise the share of tax in GDP from the present level of 9% to 26%, the level comparable to government budgetary expenditure. The replica of Nordic equality will also generate additional social welfare gain of 33% to the society. This tax policy can eliminate poverty and excessive disparities structurally if complemented with (1) land reform, (2) compulsory, standard and free education up to high school and (3) budgetary allocation in the region in proportion to the average share of population and poor. All these policies should be based on class/endowment divides; policies that aim for positive discrimination for particular groups are not justified and will be counterproductive.

I. Introduction
In 2007, Nepal’s gross domestic product (GDP)—the value of final goods and services produced
in a country in a year—was 720 billion Nepali Rupee (Rs), which at the official exchange rate,
amounts to about US$10 billion. Nepal is one of the poorest countries in the world with a per
capita GDP of US$ 234 (in 2000 prices), ranking 163rd out of 179 countries ranked in the world
while all 16 laggards are sub-Saharan countries. In comparison to its neighbours, Nepal’s per
capita GDP is only 36% of India’s per capita GDP of US$ 634 and 15% of China’s per
US$1,595. This disappointing performance has been the result of extremely sluggish growth
rates. In the last 25 years, the average per capita real income growth in Nepal has been only
about 1.8%, compared to 4.2% in India and 8.8% in China. With such growth rates, to double the
per capita income, it will take 40 years for Nepal, compared to 17 years for India and less than 9
years for China. Nepal is a laggard not only compared to the globally fastest growing two
neighbours, India and China, but also compared to many countries in the world.
Equally appalling is how asymmetrically economic opportunities are distributed across
regions and across different ethnic, language and caste (ELC) groups. These inequalities—the
direct outcome of wrong economic policies—have inhibited economic growth and have
substantially reduced the welfare of the society. The major policy mistakes have been pouring
budgetary resources into a handful of urban centres, deliberately ignoring tax on income and
wealth and relying on regressive indirect taxes and foreign aid to finance "grandiose" programs.
Moreover, the negative effects of growth-reducing and inequality-enhancing economic policies
are magnified by neglect of education and health services for the ordinary mass and adoption of
urban and elite centric education and health programs.
3
Just to give an example of, how the government is creating "elite" urban centers, research
shows that between 1999 and 2003, annual per capita government expenditure in Kathmandu
valley (three districts), with population of 7.2%, was Rs 28,000 compared to Rs 1,774 for the
region of Sagarmatha (eight districts) which houses a population of similar size (see Acharya,
2008 for fiscal disparities by regions).2 In foreign aid, the respective amount for the Kathmandu
and Sagarmatha regions were Rs 7,235 and Rs 245. This is just an example of how lopsided the
budgetary measures have been, and with such type of government policies, it is no surprise that
the economy stagnated and conflicts arose.
If there is any lesson to learn from the past, it is that for Nepal to be a peaceful, stable and
prosperous society, economic policies must unleash the forces of growth and at the same time
allow the benefits to be distributed in a more equitable manner. At present, Nepal is at the
crossroad of charting its political and economic restructuring, going from a unitary system to a
federal system. However, the debate on how to restructure has been rather cursory, as the focus
of political parties and ethnic representatives has been mainly confined on whether federalism
should be based on ethnic divide. No doubt, this is an important issue, but the actors seem to
have forgotten the fact that political entity is a mechanism or means to obtain political,
economic, social and cultural ends. Hence, the debate should revolve around federalism based on
what foundations (ethnicity, geography, culture, distribution of natural resources, market
accessibility, and services delivery) would provide the most efficient state machinery in
developing inclusive democracy, accelerating economic growth and ensuring equality of
opportunity (see Acharya, 2007, on how to restructure federal Nepal).
2 Kathmandu region includes districts of Kathmandu, Bhkatapur and Lalitpur. The Sagrmatha region includes eight districts: Ilam, Sankhuwasabha, Solukhumbu, Bhojpur, Khotang, Okhaldhunga, Dharan, and Udayapur.
4
Worse, there is hardly any serious discussion on what different economic and social
policies are necessary for a federal Nepal. It seems likely that most of the political parties are
going to continue the same old polices, which will be a recipe for deepening crisis with further
disparities in socio-economic opportunities among different groups and regions. These policies
can neither maintain peace nor unleash the forces of growth in Nepal, no matter how "rightly"
the political restructuring is done and how politically inclusive the system is. Conducive political
restructuring is necessary, but that alone is not sufficient for economic growth and equitable
opportunity. Rather, what is required is a set of companion complementary economic policies.
Such economic policies should address the root causes of poverty, inequality and stagnation.
For that, we need to understand the state of the economy at the national and at the
regional level. Also since the inequalities have ethnic, caste and other dimensions (as recognized
by Sen (1997), we have to understand these aspects as well. As far as we are aware, there are no
papers in this line of research. Against this backdrop, the objective of this paper is to provide
answers to the following questions: How deep and widespread is poverty in Nepal? How sharp
are regional, ethnic disparities in Nepal? What is the root cause of the miserable state of the
nation—is it the outcome of regional, ethnic and gender disparities or the poverty across the
board? And, what policy responses are required to turn the nation from a state of gloom to a state
of bloom?
The regional and the ELC groups considered in the paper are the same 13 regions and
groups that are identified as building blocks for a federal Nepal in Acharya (2007). We have
used data on Population Census of 2001 and Nepal Living Standard Survey II of 2003/2004 for
the study. We agree with Sen's (1997) notion that the relevant dimension of inequality should
include not only income (or expenditure) but also literacy, health achievements, self-esteem, and
5
other aspects of well-being—the basic capabilities in his terminology. Notwithstanding the
shortcoming of relying only on income (or expenditure) as a measure of inequalities, we do so in
the paper for two reasons and with two caveats. First, the inequalities in basic capabilities
correlate directly with income inequalities across regions and ELC groups in Nepal. Second, the
dealing of education and health by regions and ELC groups, which is the focus of this paper,
deserves separate study each. The related caveats are that the inequalities measured in the paper
are vital part of inequalities but they would have been more pronounced had we used the
capabilities approach. Furthermore, had there been data on wealth and assets, their inclusion
would have also sharpened the inequalities. So the inequality measures that we present based on
expenditure only will underestimate the reality.
The main findings of the paper are as follows. There are wide disparities in income (or
consumption expenditure) both by regions and by ELC groups. The richest region and group is
about four-times richer than the poorest counterparts. For example, the per capita expenditure of
the richest region Kathmandu is more than four times higher than that of Khaptad, the poorest
region. Similarly, the richest ELC group Newar has four-time higher income than that of poorest
Awadhi speaking group. The per capita expenditure of the second richest group, Gurung, is only
68% of Newar's and that of the third richest group, BC, (Brahman, Chhetri, Thakuri and Sanyasi)
is only 60% of Newar's. The disparities across regions can be termed as between-region or inter-
region disparities (similarly, across ELC groups disparities can be termed as between-ELC or
inter-ELC group disparities).
As a result of income disparities, about one-third of Nepal’s population live below the
poverty line defined at expenditure of Rs 7,696 per person per year (a very conservative
threshold). As in per capita expenditure by region and ELC groups, there are wide differences in
6
the percentage of people that are below poverty line, ranging from 4% in Kathmandu region to
48% in Khaptad region and from 14% in Newar to 70% in Awadhi speaking group. The largest
numbers of poor are in BC groups, the third richest group after Newar and Gurung. We compute
the amount that is required to bring every poor who are below poverty line at the poverty level
amount by regions and groups, a roadmap for any government who is sincere in eliminating
poverty in Nepal.
The cost of inequality cut across all ELC groups. The plight of the poor in the three
richest groups is equally precarious as poor of any other groups. To cite a few results, out of 7.2
million poor in Nepal in 2003, 1.2 million are BCs. Even though on average Newar are richest by
wide margin than any other group, and they have less number of people under poverty, those
who are poor are desperately so. For example, to bring a single poor Newar at the poverty line
amount it would cost almost Rs 2,000 (almost one-quarter of poverty level amount). The same is
true for poor in Gurung community.
Not only are inter-region and inter-group disparities high as explained above, but even
more alarming are the intra-region (among people within a region) and intra-group disparities.
The richer regions are more unequal, and richer groups are more unequal among its residents
than their poorer counterparts. The richest region Kathmandu and Annapurna are the most
unequal regions. The poorest region Khaptad is the most egalitarian one. Similarly, the richest
group Newar, Gurung and BC are the most unequal ones. As a result of these within inequalities
the rich regions and rich groups are not as well off as they would have with the same level of
income and less inequality. The richness has not translated into higher social welfare; it has been
wasted as a cost of inequality.
7
Comparison of inter-region (between) and intra-region (within) disparities shows that at
the regional level, about 25% of Nepal’s inequalities is explained by regional differences (inter-
region) and the remaining by differences among individuals within a region (intra-region). These
within region inequalities are driven mainly by three regions (Annapurna, Kathmandu and
Lumbini). Again, this is the outcome of government budgetary spending in some urban centers,
while neglecting regional balances. In terms of ELC groups, the share of within-group (in total
inequalities) is even higher than that of within-region. The high within group inequalities is
driven mainly by massive inequalities among the Newar and Gurung communities and to some
extent among BC and Rai communities.
Our results show that if there is a government committed to bringing Nepal on a growth
path, it is plausible. By adopting the model of one of the Nordic countries, Finland for example,
Nepal would benefit immensely. Our thought experiment shows that if we could bring Nepal to
the level of Finland in terms of equality index, Nepal should impose additional tax rates of 46%
in income to its richest 20% population. By doing this, Nepal would collect additional resources
Rs 88 billion and the share of tax revenue in GDP would increase from the present level of 9% to
26%. With this changes, it would take only 14% of tax revenue to eliminate poverty. The rest of
the resources could be used for public education and health services and to reduce taxes on
international trade and goods and services. Furthermore, by adopting the Finland level of
inequality, the social welfare of Nepal (the welfare of all Nepalese) would increase by 33%, from
208 billion to Rs 278 billion (calculation based on 2003 as base year). If you find these numbers
large, yes, indeed, they are. But what they show is that it is possible to bring the country out of
poverty, and to break the stagnation caused by inequalities. What are needed are consolidated
growth-enhancing and inequality-reducing policies.

The rest of the paper is organized as follows. In Section II, we describe the data followed
by groundwork on how the regions (that are used for the study) are formed and which ethnic,
language and cultural groups are considered for comparison in Section III. The theoretical
methodology for welfare, inequalities and poverty is provided in Section IV. Based on this
literature, we compute and discuss poverty by regions and groups in Section V. Similar analysis
on inequalities is carried out in Section VI. The welfare analysis is covered in Section VII
followed by conclusion and recommendations in Section VIII.
II. Data
The paper uses macro level data from 2001 Nepal’s Population Census and household level data
from second Nepal’s Living Standards Survey (NLSS II), conducted in 2003/2004. The
Population Census data are used to identify the regional blocks and ethnic, language and caste
(ELC) groups that become the units of analysis for the paper. Once the regions and groups are
identified, we use the household level data from NLSS (II), a follow up survey of NLSS (I)
conducted in 1995/1996 by Central Bureau of Statistics, and based on the methodology of Living
Standards Measurement Survey methodology developed at the World Bank and applied in more
than 50 developing countries (for detail on the survey, see Central Bureau of Statistics (2004).
The survey used a two-stage stratified sampling approach: a nationally representative
cross-section survey to estimate trends and levels of socio-economic indicators in the country
and its different geographic regions; and the second component was a panel survey to track exact
changes experienced by those previously enumerated households during last eight years. In the
paper, we will use the data based on cross-section part of the survey only.
9
Using 2001 Population Census of Nepal, NLSS II survey took the size of each ward
across Nepal (as measured by number of households) as a unit of sample frame, where bigger
wards were divided and smaller one were appended into neighbouring wards. The resulting
sampling frame consisted of 36,067 enumeration areas (wards or sub-wards) covering all 3,914
Village Development Committees (the smallest political entities) of the country. For the cross-
section part of the sample, first 334 Primary Sampling Units (PSU) were selected from six
explicit strata (Mountains, Kathmandu valley urban area, Other Urban areas in the Hills, Rural
Hills, Urban Terai and Rural Terai) of the country. Then 12 households in each of 334 PSU were
selected randomly, with total of 4008 households.3 We use NLSS II extensively because this is
the representative sample survey for all regions and population groups which provide
information on income and expenditure.
Besides, data are also taken from World Development Index database compiled by the
World Bank and website maintained by different institutions.
III. Unit of Analysis
Since the focus of the paper is to investigate the region-wise and group-wise comparisons of
economic condition, the selection of regions and groups for unit of analysis is an important issue.
So far, the regional analysis studies have used ecological belts and/or (Himalaya, Hill and Terai),
rural-urban dichotomy (see Pradhan and Shrestha, 2005; World Bank, 2006a; World Bank
3 The allocation of cross section PSUs by districts were as follows. Taplejung 4; Morang 16; Sunsari 11; Solukhumbu 3; Panchthar 3; Dhankuta 4; Bhojpur 4; Okhaldhunga 2; Ilam 5; Tehrathum 2; Khotang 3; Siraha 8; Jhapa 13; Sankhuwasabha 5; Saptari 9; Dhanusa 11; Udayapur 6; Makwanpur 8; Ramechhap 3; Lalitpur 10; Mahottari 8; Rautahat 7; Dolakha 5; Bhaktapur 6; Sarlahi 9; Bara 8; Sindhupalchok 10; Kathmandu 6; Sindhuli 5; Parsa 7; Kavrepalanchok 7; Nuwakot 5; Dhading 6 Kathmandu 35; Chitwan 9; Tanahun 5; Syangja 7; Gorkha 5; Kaski 14; Gulmi 5; Lamjung 4; Myagdi 3; Palpa 4; Manang 1; Parbat 2; Rupandehi 10; Nawalparasi 8; Baglung 4; Arghakhanchi 4; Kapilbastu 8; Banke 7; Bardiya 5; Doti 4; Pyuthan 4; Surkhet 7; Kalikot 3; Kailali 8; Rolpa 3; Dailekh 4; Mugu 2; Kanchanpur 5; Rukum 2; Jajarkot 1; Bajura 3; Dandeldhura 2; Salyan 3; Dolpa 1; Bajhang 4; Baitadi 4; Dang 6; Jumla 1; Achham 4; Darchula 3; Humla 1.

2006b). For groups, the existing studies use rather aggregate ethnic groups by lumping several of
them into a few groups. These types of studies are not very helpful in designing policies that
require regional and/or group-specific dimensions. Here, we follow the approach taken by
Acharya (2007), where regions or groups are formed based on common characteristics, the brief
discussion of which is provided below.
According to population Census 2001, there are 23 groups, which constitute at least one
percent of Nepal’s total population. Based on common threads such as ELC, Acharya (2007) has
combined them into distinct 13 groups as given in Table 1 (not counting “others” which
comprises several small groups).
Table 1. Nepal’s population composition by broader caste/ethnicity in 2001 Number of districts with
Ethnic, language and caste groups Share in total population Majority (&
plurality) 2nd place
1. Brahman, Chhetri, Thakuri, Sanyasi 30.9 19 (46) 19 2. Maithali speaking 12.3 5 (5) 1 3. Bhojpuri speaking 7.5 3 (4) - 4. Awadhi speaking 2.5 1 (2) - 5. Hill Dalit 7.2 0 (0) 15 6.

Others 3.3 0 (0) 3 Total 100 33 (75) 72 In column 4, we have total of 72 districts at the last row because due to lack of data on language, Acharya (2007), was not able to identify which group is in second position in the district of Jhapa, Morang and Siraha. na: not available
Brahman, Chhetri, Thakuri and Sanyasi (BC hereafter), is the largest group with 30.9%
(column 2, population groups presented in descending order of their shares) of Nepal’s
population. They are in majority (more than 50%) in 19 districts and in plurality (with highest
11
fraction but less than 50% of population) in 46 districts (column 3). Column 4 shows in how
many districts each group is in second place.
In an effort to maximize the concentration of ELC groups in a region other than BC,
Acharya (2007) identifies the focus districts for each of these groups—a district is considered a
focus district of an ELC group if that group is at least the second largest fraction after BC in the
district. Hence, if that group is in majority, or in plurality, or second largest after BC in the
district population, then the district will be the focus district of that group. Then all districts that
qualify to be focus ones for a given ELC group are combined to make a focus region for that
group. By this mechanism, 11 regions were identified as focus regions for 11 groups except for
BC, Muslim and "others". Since BC group is either in majority or in second place in most of the
districts, the exercise of identifying focus regions was not applied to BC.4
These 11 ELC groups and their respective focus regions are: Limbu (Kanchenjunga), Rai
(Sagarmatha), Tamang (Gaurishanker), Newar (Kathmandu), Maithali speaking (Mithila),
Gurung (Annapurna), Magar (Ridi) Bhojpuri speaking (central terai), Dalit (Khaptad), Awadhi
speaking (Lumbini) and Tharu (western terai). Sixty-eight districts were considered as focus
districts and were allocated that way. Of the remaining seven districts, in three districts in the
eastern Terai (Jhapa, Morang and Sunsari), majority or plurality of people seems to speak Nepali
and it was not obvious at what criteria these could be called focus districts for any of ELC group.
Hence these three districts compose a region without any focus group. The remaining four
districts are located in the most remote area of Nepal and they will be considered separately,
thereby making 13 regions, for the analysis. Based on this criterion, Acharya (2007) has Table
showing the number of districts, population of its focus groups and all other groups which is
12
reproduced as Table A1 in the appendix. We have also included the map of Nepal based on those
13 regions in the Appendix as Figure A1.
Our regional analysis will be based on 13 regions, whereas ELC analysis will be based on
12 groups, all the groups shown in Table 1 except Muslim and "others". The Muslims will be
included in the linguistic groups of Terai (where most of their sample is from), and we have left
the "others" category out of study in ELC comparison as it contains several groups and is not
very useful for policymaking. Each region has its own focus groups (except BC, which can be
considered as focus group for Rara special region), but the region east Terai has no focus group,
hence one unit less than in the regional analysis. With this established unit of analysis, next we
discuss the methodology we will be using for measuring poverty, inequality and social welfare.
IV. Methodology on Welfare, Inequality and Poverty Measurements: An Overview As discussed above, the objective of this paper is to look at the economic well-being of Nepalese
by regions and major ELC groups. In doing so, we concentrate on poverty, income distribution
and welfare of the defined regions and ELC groups. We follow the emphasis given by
researchers in integrating poverty and income distribution analysis in a coherent single
framework (Atkinson and Brandolini, 2008; see Deaton (1997) for lucid integrated expositions
of three concepts, welfare, poverty and inequality). We start with a social welfare function for
the government which is the welfare of all individuals/households in the economy.
(1) , ( )1 2, ,..., nW v y y y=
4 Understandably the latter category could have a natural homeland because it combines several very small groups. The Muslim group, however, represents 4% of the population and does not have a focus district because they are quite scattered. One of other groups given in Table 1 is higher in number than Muslims in all districts.
13
where W is the social welfare and y's are some measure of living standard and n is size of
population in the country.5 We know that neither the living standard can be measured by one
variable nor the government actually selects level of individual's living standard as implied by
(1) but this type of representation is common in economics and allows us to focus on two most
important issues in economics: efficiency and equity, and hence on poverty, inequality and
welfare. Under the condition that proportional changes in all y's have the same proportional
effect on the aggregate social welfare, (1) can be written as:
(2) 1 2, ,..., nyy yW vμμ μ μ
⎛ ⎞= ⎜ ⎟
⎝ ⎠,
where μ is the mean of all y’s. If there is perfect equality, everyone would have mean level, μ, of
welfare. Then by the principle of transfers, first expounded by Dalton (1920).—the concept that
welfare will increase by any transfer of y from a richer to a poorer person, provided that the
transfer is not sufficiently large to change the relative position of these two individuals—social
welfare for any unequal allocation cannot be greater than the mean of the distribution, μ. Hence
(3) ( )1W I σμ= − ,
where I is the measure of inequality, taking the value of zero when the y’s are equally distributed
and increasing with disequalizing transfer; σ ranges from 0 to 1, can be considered a ethical
value that one would provide to the cost of inequality. The value of 1 implies that any degree of
inequality is a cost and is given by Iμ , meaning that the cost of inequality is equal to the amount
by which social welfare falls short of maximum that would be attained under perfect equality.
When σ takes the value of 0, then W = μ, inequality is taken out from the consideration of social
welfare function. Some argue that equity and efficiency are separate components of welfare, and
5 Y could be vector of basic capabilities such as income, education achievement, health provision, gender equality
14
by allowing the value of σ to vary, one is giving an opportunity to balance the mix of efficiency
and equity (see Graff, 1977 and Atkinson, 1992). In any case, the choice of value for σ
represents ethical judgment on how costly the inequalities are for welfare. One thing is clear
though, whatever value is given to σ in (3), we cannot interpret measures of inequality as
measure of welfare. In our work below, we will use the value of 1 which is more common in
literature (Sen, 1976a; Deaton, 1997) and also 0.5.
Now, the next issue is how to measure inequality, I is social welfare function (3). One
can generate measures of inequality by specifying a social welfare function and solving for the
inequality measure, or starting from a measure of inequality and inquire with a social welfare
functions. We follow the first route and discuss Atkinson’s inequality measure which starts with
additive social welfare function6:

where 0ε ≥ is “inequality aversion”, the higher value of ε, the more society is concerned about
inequality (Atkinson, 1970). The inequality measure associated with (4) is then

The Atkinson measure of inequalities, AI , range from 0 to 1, with zero representing no
inequality. The Atkinson measure in (5) is a special case of Generalized Entropy class of
inequality, EI , which we introduce below, as we will be using this measure in decomposing total
inequality into "within" and "between" inequalities.
and so on. 6 Note that the expression in (1) is a general form of social welfare function, but there are different specific functional forms in the literature, and Atkinson’s is one of them.

EI ranges from 0 to ∝, with zero representing an equal distribution (all incomes identical) and
higher values representing higher levels of inequality. The parameter α represents the weight
given to distances between incomes at different parts of the income distribution. The lower value
of α is more sensitive to changes in lower tail of the distribution, and the higher value of α is
more sensitive to changes that affect the upper tail.7 The EI measure with parameters 0 and 1
become, with l’Hopital’s rule, two of Theil’s measures of inequality (Thiel , 1976). They are
called the mean log deviation and Theil index respectively and are given as follows:

Setting α = 1- ε, the EI class becomes ordinarily equivalent to the Atkinson measure (Litchfield,
1999).
The other measure used for inequality is Gini coefficient which is closely associated with
Lorenz curve.8 Gini, GI , can also be measured using direct formula, and the more convenient
one is:

7 The values that are used in the literature are 0, 1 and 2. A value of α = 0 gives more weight to distances between income in the lower tail; α = 1 applies equal weight across the distribution, while a value of α = 2 gives proportionately more weight to gaps in the upper tail. With α = 2, the With α = 2, the E measures becomes half the squared coefficient of variation EI measures becomes half the squared coefficient of variation 8 The Lorenz curve gives the distribution of income or consumption, measuring cumulative distribution of people on the x-axis (starting from the poorest) and cumulative distribution of income or other resources on the y-axis. If resources are equally distributed everyone receiving the same, the Lorenz curve will be a 45-degree line—a line of perfect equality. Gini index is the area between the Lorenz curve and the 45-degree line as a fraction of total area under the 45-degree line. If the area between the line of perfect equality and Lorenz curve is A, and the area under Lorenz curve is B, then Gini coefficient is equal to A/(A+B). Since A+B = 0.5, Gini = 2A = 1 - 2B.

where iρ is the rank of individual i in the y-distribution, counting from the top so that the richest
person has rank of 1. Note that the Gini lies between zero and one; when everyone has same μ,
the Gini coefficient is zero; while if one person has nμ and everyone else has zeros, then there
are n – 1 distinct nonzero absolute differences, each of which is nμ, so that the Gini is 1. The
associated social welfare function with Gini coefficient is one in which the y’s are weighted by
the ranks of each individual in the distribution, with the weights larger for the poor.
Now by plugging the value of inequality given by any of the expressions in (5a), (5b),
(7a), (7b) and (8), into (3), we can compute the value of social welfare. Sen (1976a) uses Gini
coefficient and measures social welfare, for Indian states using functional form ( )1 GIμ − .
Finally, we deal with poverty in the context of social welfare function. In terms of
measurement, what separates the social welfare from poverty is that the latter is defined as a
poverty line, below which people are defined as poor and above which they are nonpoor. In other
words, in the social welfare it is like giving zero weight to marginal benefits that accrue to the
nonpoor. In inequality literature, it is hardly the case that zero weight is given to nonpoor. In that
sense, poverty measures are special cases of social welfare measures. For the measurement
purpose, we start with Foster, Greer and Thorbecke concepts (1984), which can be reduced to a
couple of poverty measures.

This is called the poverty headcount ratio, which gives the fraction of population who are
below the poverty line, people in poverty. See Deaton (1997) on how (10) it can be represented
in a social welfare function. One of the drawbacks of this measure is that it takes no account of
degree of poverty, and it would be unaffected even from a policy that makes the poor even
poorer. This measure yields the same number whether the poor are just below the poverty line
are very far below from the poverty line. According to this measure social welfare can be
increased by taking money from the very poor to lift some better off poor out of poverty (Deaton,
1997). The poverty gap measure could address this limitation which is the limiting case of (10)
if α = 1. In this case, the formula is

According to (11), the contribution of individual i to poverty measure is larger, the poorer
is i. It can be interpreted as a per capita measure of total shortfall of individual welfare levels
below the poverty line. The poverty gap measure (11) has number of advantage over headcount
measure. This measure has the feature that social welfare is not altered if transferred among the
poor or among the nonpoor, it is no longer possible to increase social welfare by redistributing
resources from poor to the rich. The poverty gap measure will be increased by transfers from
poor to nonpoor, or from poor to less poor who thereby become nonpoor. But transfers among
the poor have no effect on the measure of poverty. Sen (1976b) developed poverty measure as
18
the average of the headcount and poverty gap measures weighted by the Gini coefficient of the
poor.
V. Poverty: Regional and ELC Dimensions
Using methodology developed in the previous section, we analyze poverty, inequality and
welfare among regions and ELC groups describe in Section II. First, we discuss the results based
on regions and then move to results based on ELC groups. In contrast to the methodology section
where our discussion proceeded from social welfare to inequality to poverty, here we follow the
reverse order and start our analysis from poverty. As is done in poverty measurement literature,
we use expenditure per capita rather than income per capita as the basis of our analysis. 10 The
exclusive use of only expenditure to measure inequality in the paper will somewhat
underestimates it for three reasons (showing poor people relatively better off than they actually
are).
First, in general, relatively poor people have higher expenditure than their income.
Second, the factors that are not complemented but are major part of economic well-being, wealth
and asset distribution, are more skewed towards the wealthier section of the population than
expenditure. Third, the expenditure inequality and inequalities of other basic capabilities (such as
education and heath) correlates positively thereby making poor in expenditure even poorer on
capabilities. Despite these shortcomings of our measure based on expenditure, our analysis is
very useful for policymaking. Even though we are not making full measure of inequalities, the
expenditure ranking captures the major part of it and the relative ranking of regions and ELC
10 In developing countries, a measure based on expenditure is considered more accurate than that based on income, as income tends to fluctuate more in these countries. This is true for Nepal as well where income depends, among other unstable factors, on volatile whether conditions.
19
groups, which is the center piece for policymaking, would not have been affected even if we
were able to include all factors mentioned above.
The first set of results are provided in Table A2, where average annual per capita
expenditure for all 13 regions, the poverty measures and cost for bringing all poor into poverty
line amount are shown. Column 2 shows the number of sample households that were covered in
the survey, the total of 3,912 (last row). Column 3 is the annual mean per capita expenditure,
obtained by dividing each household's expenditure by its number of household members. At the
national level, per capita mean annual expenditure is Rs 15,707.11 The median per capita annual
expenditure, however, is only Rs 10,427, implying highly skewed distribution of expenditure
toward very rich individuals. In other words, relatively a small number of high income people
have pulled up the mean value. Since our focus is to look at the relative position of the regions
and the groups (rather than absolute values), that does not change whether we use mean or
median, without any loss of generality, we base our analysis on mean expenditure.
The regional disparities are alarming. The magnitude of annual mean per capita
expenditure ranges from nine thousands in Khaptad (Dalit focus) region to, four times higher, 37
thousands in Kathmandu (Newar focus) region. The average per capita income of Kathmandu is
more than double, and that of Annapurna (the second richest and Gurung focus region) is almost
double the national average. Kathmandu is the only region whose per capita income is
comparable to India’s average GDP per capita. The other two regions with higher than national
average per capita are Eastern Terai and Central Terai. The second poorest region is
Gaurishanker (Tamang focus), followed by Kanchenjunga (Limbu focus) and Sagarmatha (Rai
11 At the conversion rate of Rs 75 per US$ (for average of years 2003 and 2004, years that the survey was conducted), this amount is equal to US$209 (US$ 0.57 for a day). At PPP conversion rate of 0.16 of the official exchange rate, this amount is equal to PPP international $1,306 ($3.6 per day).

focus) region. Western Terai (Tharu focus) is in the middle of the pack, neighbouring with
Mithial as slightly poorer region and Ridi as slightly richer region.
Column 4 (computed using equation 10) shows the percentage of people who are below
poverty line (defined at annual per capita income of Rs 7,696). The poverty line income is
defined on the basis of what is the
minimum calorie one would require
physically, a amount needed to purchase
bare minimum for subsistence. And people
falling below this line, which we call poor
in this report, are those who are at the state
of complete deprivation. Unfortunately, at
the national level, staggering 31% of people are below poverty line. Looking at the regions,
about half of the people in three regions (Khaptad (48%), Sagarmatha (47%) and Gaurishanker
(47%)) are below poverty line. The three richest regions, eastern Terai, Annapurna and
Kathmandu have less proportion of poor. For example, in Kathmandu, only 4% are poor, the
lowest percentage across regions. In Figure 1, we show the headcount and per capital
expenditure by regions.
Column 5 looks at the poverty gap ratio (equation 11), measuring the distribution of
people that falls below poverty line. When y is blow z, it contributes to poverty gap, if y is equal
to and above z its contribution to poverty gap is zero. Poverty gap can be interpreted as a per
capita measure of shortfall of individual (those below poverty line) income levels below the
poverty line. If the value of 1p = 0.1, 10% of the poverty level income has to be borne on per

capita basis to bring every poor at the poverty line income. When multiplied this fraction by z
( 1p z× ), we get per capita cost that needs to be borne to bring all poor at the poverty line.
If lump sum taxes and subsidies were possible without and inefficiency and
administrative cost, then 1p z× can be considered as a measure of the per capita cost to be
incurred in eliminating poverty. Again, when we multiply this expression by population
( 1p z× ×n ), we get total cost required to bring all poor at the poverty line amount (henceforth
this amount is referred as PLA, not to confuse with Maoist’s Peoples Liberation Army!). This is
the amount shown in Column 7 and should be read as it will cost Rs 2.754 billion to bring all
poor in Gaurishanker region at poverty line expenditure. In last column, we show PLA per poor
(amount needed to bring a single person at poverty line), and given by ( ) ( )1 1 0p z n h p p z× × ≡ .
Leaving aside the details of what these data represent, one thing is quite noticeable. At
the national level, the average per poor PLA is Rs 1,881 which about a-quarter less than the even
narrowly defined PLA. It means that not only the poor are in large number they are also
extremely poor. The average per capita PLA is as high as Rs 2,449 for Sagarmatha and Rs 2,356
for Gaurishanker region.
Looking from the national perspective, with national estimate of poverty gap of 0.076,
poverty line of Rs 7,696 and total number of population of 23.56 million, the PLA for the nation
is equal to about Rs 13,694 million (= 0.076 x 7696 x 23.56). So we can eliminate the defined
level of poverty with Rs 14 billion (rounded for simplicity). How big is Rs 14 billion at 2003
prices? It is 2.8% of Nepal’s 2003 nominal GDP of Rs 492 billion. Was it possible to cover this
amount by tax instrument or by achieving higher growth? Let us discuss mobilizing tax first.
Take an example of direct tax. In 2003, Nepal’s tax on income, profits, capital gains and
property was 2% of GDP at about Rs 8.5 billion (all figures in this example will be rounded to
22
make comprehensible). The additional tax of Rs 14 billon would make the total revenue from
this tax equal to Rs 22.5 billion. Then the share of this tax in total tax revenue in GDP would
have been 4.5%. How high is this ratio compared to our neighboring country India? India’s
income, profit and capital tax in 2003 was about 4.6% of GDP. So, it is completely plausible to
finance Nepal's poverty by mobilizing additional income, profit and capital gain taxes which are
very low presently and its negligible rates have distorted other economic activities negatively.
Indeed, later in the paper we will show that it is actually desirable to raise the share of income,
profit and capital gain and property tax in GDP to a very high level so that the tax revenue share
in GDP rises from present level of 9% to almost 30% in order to have equitable and efficient
economy.
Second, let us look from the growth aspect. Had Nepal’s GDP been grown at the rate of
India’s GDP, about three-quarters of that additional growth (India’s growth minus Nepal’s
growth) were enough to fill the poverty gap.12 Had Nepal achieved China's growth pace, it
would not have taken even half of the growth differential to eliminate the poverty. So looking
from either redistribution (tax) aspect or growth aspect, it's quite feasible to eliminate pove
However, we argue that unless ownership structure and other economic and social policies that
generated this poverty are addressed first, it is unlikely that Nepal could accelerate its GDP
growth rates in a substantial way. However, mobilizing higher income and profit taxes is not
only possible but also highly desirable from both efficiency and equity aspects.
rty.
Was there any attempt from the government in mitigating this deprivation? One could
argue the deprivation that started with asymmetric economic endowments, government
aggravated it through wrong budgetary priorities over time. In Table 2 we provide some
12 Note that Nepal’s GDP grew by about 3.7% whereas that of India and China grew by 7 and 9.5% annually from 1997 to 2007.
23
evidence on that line. Take Gaurishanker region. This region has about 11% of Nepal’s
population, requires 20% share of PLA to eliminate poverty but has received only 6% of
government expenditure annually, in the last five years. This region receives half of what it is
entitled on population proportionality and not even one-third of what is required to cover
poverty. In other words, the region needs double the share of resources than its population share
to cover poverty but the government is putting half the share of resources than its population
share. In Mithila region, the case is worse. The story repeats to several other regions.

The third column is taken from Acharya (2008) and shows the annual average share of government expenditure based on four years (1999-2003).
All resources are poured in Kathmandu (50%) to serve 7% of the country population.
This mismatch of population settlement and resources use has been the major reasons for Nepal's
socio-economic problems. This attempt by the government to "develop" urban "elite" centers has
not only made other parts of the country deprived of public services, it also has created enormous
distortions in the resource allocation. Hardly any investor in Nepal wants to invest in other
24
activities rather than buying real estates in these urban centers. The reason is that the price of real
estates in these centers are skyrocketing, as people throughout the country who can afford flux to
these centers to get schooling, hospitals and other facilities provided by government treasury.
Hence, the real benefits of the government resources are translated into private gains to the minor
fraction of the population who can afford to be in these centers by imposing huge costs to the
society. The poverty and inequalities are the cumulative outcome of these wrong policies.
It is important to allocate government expenditure in such a way that the regions which
are poorer should get higher shares than their population shares. This, we see as a minimum
requirement for building a efficient, peaceful and just society (on how to allocate resources in
federal Nepal, see Acharya (2009a)).
Before leaving this section, it should be noted that the average income of the poor in all
regions is very similar around 5-6 thousands as shown in column 5 (mean of the lowest 30%) of
Table A2. This is not surprising given the fact that the poverty line is defined at such a meager
amount and must of them might fall below that amount (note that 31% is the national cutoff for
poor and nonpoor), there is not much room for bigger discrepancy, as this is the barely
subsistence level. However, this no matter which part of the country they live, the 30% people
have almost the same level of deprivation. The only difference is that some regions have higher
proportion of people under poverty.
Next we examine the poverty measures by major ethnic, language and caste groups. A
question may arise what different results we can expect when the regions that were the basis of
analysis above were also formed using the ELC settlement clustering. It is true that the regions
are formed in a way that the share of ELC group in its focus region's population is maximized.
Despite this mechanism, as is clear from Table A1, only two groups are in majority in their focus
25
regions’ population, other nine groups are second place after BC. Furthermore, it is the case that
significant portion of ELC members live outside of their own focus region. Therefore, the results
based on regions may not collaborate with those based on ELC groups. Furthermore for a
policymaking purpose, it is important to know poverty and inequality measures based on ELC
groups. More so in Nepal today, where the class divide and ethnic divide seem to be
complementing each other, sometime creating confusion whether appropriate policy should be
class based or ethnicity based.
We have provided the poverty measures by 12 ELC groups in Annex Table A3. Again,
the inequality is equally alarming as was the case across regions. The per capita expenditure of
richest group (Newar, with Rs 32,696) is four times higher than that of poorest group (Rs 7,754
of Awadhi speaking group—level, not very different from poverty line). To put it another way,
with average family of four, an average Awadhi speaking family has the same level of
consumption as that of an average member in the Newar community. This is a startling level of
inequality. Newar’s per capita expenditure is more than double the income of national average.
Gurung, which has the second highest per capita expenditure, has only 68% per capita
expenditure of Newar. The BC's has per capita expenditure is Rs 19,370, less than 60% of that of
Newar.
In Awadhi speaking community 70% are below poverty followed by Tamang (61%), Rai
(49%) and Limbu (41%). There are only
three groups, the same three groups that
have the highest expenditure, that have
less headcount ratio than national average
of 30.9%. Among them, the lowest 0

poverty headcount is in Newar (14%), with similar ranking for BC and Gurung at 18%. In Figure
2, we plot the per capita expenditure and poverty headcount by ELC groups.
In terms of per capita PLA, the highest amount required is for Tamang at Rs 2,776 (36%
of poverty line income). The second poorest member is from Rai group who requires Rs 2,320
per capita PLA. One interesting point is that a poor Newar, whose group has such a high per
capita expenditure and so low headcount ratio, requires quite a large amount to get out of poverty
(Rs 1,936). It reflects that those Newar who are in poverty are a lot poorer than own ethnic
members, more so than poor from other ethnic groups while compared to their counterparts. This
also is a clear indication that if social or economic programs are designed based on ethnic, caste
or language groups, rather than on income/economic aspects, we are going to miss the target at
best and aggravate the situation at worst. By targeting ethnicity, we might be making already rich
person a super rich in that group, whereas neglecting the poor from other non-targeted
population section in perpetual deprivation.
Altogether there were about 7.3 million people under poverty in 2003, whose
distribution by ELC groups is given in Figure 3. The largest numbers of poor are BC, 1.19
million. The second largest number of poor
are Tamangs and the smallest number are
Gurungs. From poverty alleviation point of
view, what is important is the number of
people that are in poverty not the share of
poor in any particular group. As a result,
we have presented the absolute number of
poor in this diagram. One point that clearly

emerges from this figure is that although BC group ranks third after Newar and Gurung in per
capita expenditure, there are largest numbers of poor in this group. This is further evidence that
the poverty alleviation programs should not be targeted for some section of the population; they
should be very general and should target the poor based on class division. Any positive
discrimination in terms of ELC could restrict the participation of these poor from BC group,
making the policy counterproductive both from equity and efficiency points of view.
VI. Inequality: Regional and ELC Dimensions
The poverty measure provided in Tables A2 and A3 capture the incidence of poverty (percent of
poor), and inter-region and inter-group comparisons of poverty and income distribution. But it
does not tell us about how unequally distributed the expenditure is across members within a
region and across members within a group. In other words, these measures do not tell us about
within region and within ELC group inequalities. That will be dealt in this section. In Table A4,
we provide three measures, Gini coefficient (equation 8b), Generalized Entropy with α = 0
(given by equation 7a and denoted by E(0) in the table) and Atkinson’s measure with ε = 1
(given by equation 5b and denoted by A(1) in the table). Note that the value of α = 0 is
consistent with having ε = 1, as discussed in Section III. These inequality measures for regions
are within region and for ELC groups within group inequalities.
Whichever three measures is used, the ranking of regions based on inequality coefficients
is the same. Annapurna is the region with most unequal distribution with Gini of 54%, E(0) of
51% and A(1) of 40%. The second most unequal region is Lumbini with Gini of 46%, followed
by Kathmandu, Sagarmatha and Central Terai. Leaving aside the Rara with lowest Gini of 26%,
the most equal regions are Khaptad (Gini of 26%) and Kanchanjunga (with Gini of 29%).
28
Annapurna, Lumbini and Kathmandu are the regions that have higher Gini coefficients than that
for the nation (more unequal than the nation). Kathamandu and Annapurna regions are the
richest ones and the high within inequalities indicate that the richness is not distributed across.
The similar measures for 13 ELC groups are given in Table A5.13 As in region, group-
wise ranking of inequality measures is the same whichever of three measures is used. The most
unequal group is Newar (with Gini of 53%), followed by Gurung (Gini of 48%), others rich and
BC (with Gini of 44%, same as for the nation). Hence, the richest three groups (Newar, Gurung
and BC) are also the most unequal ones. The poorest Dalits are also the most egalitarian ones. As
a result in terms of welfare measure, the richest three groups are not as much better off as in
terms of per capita income; they have higher cost of inequality to incur which we will discuss
later.
Next, we want to complement these within measure of inequalities with between
measures. The methodology for decomposing the aggregate inequality into two components,
within and between, started with Bourguignon (1979) and there have been several papers after
(see, Shorrocks and Wan, 2004; Cowell and Jenkins,1995). Among the measures of inequality
that are consistent with decomposition are Generalized Entropy members including Atkinson’s
measure. Gini can be decomposed but it will have residual, which does not have a straight
forward interpretation.
We provide the detail decomposition in Annex B for Generalized Entropy when α = 0,
E(0), which shows that the final formula turns out to be as follows (given as equation B4 in
Annex B):
13 Note that here we have put three language groups (Maithili speaking, Bhojpuri speaking and Awadhi speaking, into one as Medhesi group). And we included two “others" categories. "Others" includes the mostly marginalized groups and "others rich" includes relatively affluent group (Bengali Marwari, Punjabi, and Thakali).

replacing the income of each person by mean income of the region the person resides. Thus the
overall level of inequality of a country is the exact sum of average inequality within region and
inequality due purely to differences in average income between regions. Inequality falls if the
relative income across all individuals in region r are equalized (within component) and aggregate
inequality falls if regional mean income differences are eliminated, holding constant relative
incomes within region
Using formula in 12 for the results given in Table A4 (for regions) and A5 (for ELC
groups), we can compute the within component inequality for Nepal. And using the mean
expenditure from Table A2 and A3 we can compute the between component for Nepal. The
results are given in Table 3.

and remaining 19 to 24% is between regions. Our range includes the 23.7% share of between

inequality measured by Elber et al (2007) with 10 groups in Nepal).14 By international standard
between-region inequality of this magnitude (close to one-quarter of total inequality) is high,
indicating that Nepal has a lot of regional disparities. The results show that about three-quarter of
inequalities in Nepal are across people within the same region. The within group inequalities (in
the range of 80 to 88%) are even higher than within region inequalities. The members of the
same groups are more unequal than members of the same region. The results mean that at least
80% of inequality is spread across members of the same ELC group. This finding intra group
disparity suggests that any inequality reducing programs should be class based not particular
group based.
VII. Welfare Measure
Finally, we compute the welfare and cost of inequality using the expression given in
equation (3) and taking Gini coefficients as measure of inequality. In most part of the analysis,
we use σ = 1, meaning that each Rs of inequality generates equivalent amount of cost. This may
sounds radical, but this is the value frequently used in the literature. Sen (1976) uses this concept
in ranking Indian states and Deaton (1997) uses this concept to see the welfare differences
between black and white during Apartheid regime in South Africa. Moreover, those who are
following Nepal’s stagnation, loss of lives, illiteracy, and strike-crippling economy, assuming
value of σ at unity is somewhat realistic. These all social evils are the costs associated with, to a
greater extent, inequalities. We also use σ = 0.5 towards the end. But the logic of the analysis
and the policy prescription provided using σ = 1 is equally valid for any values of σ, only the
magnitude of effect differs.
14 For more recent on how the between group measure is sensitive to number of partition, see Elber et al. (2007) and
31
The cost of inequality varies by regions as do their Gini coefficients. For Kathmandu
which has very high Gini coefficient, with per capita expenditure of Rs 37,031, the welfare is
equal to just Rs 20,784 and the inequality cost is Rs 16,247 per dweller in Kathmandu region.
The per person cost of inequality in Annapurna region is Rs 15,857. Because of this inequality,
Kathmandu region, which has four times higher per capita expenditure than that in the poorest
region Khaptad, is only three-times better-off than Khaptad in terms of welfare. Note that what
matters for the living standard is the welfare not per capita income or expenditure.
At the aggregate level for Nepal, we show the welfare and cost measures in Table 4 (row
1 with Nepal’s inequality). With national per capita expenditure of Rs 15,707 (Table A2), the
welfare will be equal to Rs 8,864, and the welfare cost is equal to Rs 6,864. If we multiply this
per capita numbers by total population of 23.56 million, we get the total welfare of Rs 208
billion and whopping cost of Rs 162 billion. Although the economy has total expenditure of Rs
370 billion (shown in last column), 44% has been wasted as cost in terms of social welfare.

Next, we do a thought experiment, the sketch of which is as follows. Looking at Nepal’s
poverty and inequalities we feel that the best model for Nepal to adopt is that of Nordic
(Denmark, Finland, Iceland, Norway, and Sweden) regions. On that premises, we want to choose
average Gini of the Nordic (developed capitalist) countries in terms of inequality and using their
indicators we want to compute two things: (1) what would be the welfare gain for Nepal in table
Rao and Lanjouw (2008).
32
4 by adopting the representative Nordic country's equity preference, and (2) what should be the
tax rate that Nepal should impose to attain that level of equity.
In Nordic countries, the median Gini seems to be that of Iceland (0.25) but we take that
of Finland (0.26), which is second highest among five Nordic countries (Wikipedia, website).15
The region in Nepal with Gini that is closer to that of Finland is Khaptad which, interestingly,
has the same Gini (0.264 to be precise). The welfare and cost calculation for Nepal based on Gini
of Finland is given in Table 4 (row 2). The cost of inequality with actual Gini of Nepal falls from
162 billion to 98 billion with Finland's Gini. Consequently, the welfare rises from Rs 208 billion
to Rs 272 billion. So if we maintain income distribution like in Finland in Nepal, it would
transfer Rs 64 billion cost of inequality into social welfare gain. The increase in welfare from
Nepal’s Gini to Finland’s Gini is 31% (=64/208).
Even if one would like to use smaller value of σ, the trend in the benefit is the same, only
magnitude changes. So far we have used ( )11 GW Iμ= −
)0.5I
and used Nepal’s Gini and Finland’s
Gini. Even if we consider , being very tolerant to inequality (meaning that only
half of the inequality is considered as costs), still Nepal’s welfare would increase by 15% from
Rs 277 billion to Rs 317 billion, if inequality was eliminated.
(1 GW μ= −
Next, we calculate the tax rate that Nepal needs to adopt if it wants to be as equal as
Nordic countries. For that purpose, we take the income share of the richest 20% and poorest 20%
in these Nordic countries and calculate their ratio. We do the same for Nepal and then compare
what should be the tax rate in Nepal for the richest 20% people if we want the rich in Nepal to be
in the same footing as the rich in Nordic regions, compared to their poorest 20% compatriots.
15 In 2005, the Gini coefficients for Sweden was 0.23, for Denmark 0.24, for Iceland 0.25, for Finland 0.26 and for Norway 0.28. For India the Gini was 0.36, and for Canada 0.32. In Nepal's case we have used o.437 which is based
33
The income shares of these two groups for different countries are given in Table 5. Among the
countries listed, the level of disparities in Nepal is mind boggling. The richest 20% people
receive 54.6%, more than half, of Nepal's income. Their income is nine-times the income of
poorest 20% in Nepal, whereas in Nordic countries the income level of the richest to the poorest
20% is at factor of 4.
These income shares are based on before-tax income. If we consider after-tax income
(which is more relevant concept in inequality measure) the poor of Nepal vis-à-vis their richer
counterpart compared to Nordic region’s poor vis-à-vis their richer counterpart ranks even
worse. Because of highly progressive tax system in Nordic region (pay according to ability), the
after-tax income factor of richest to poorest 20% will be substantially smaller than 4. But in
Nepal, as the tax system is almost regressive (as the share of direct tax is low most of the tax
coming from goods and services including necessities) the after-tax income factor will only
slightly lower than 9.16
Next we ask the following question. What percent of income has to be taken out from the
richest 20% people in Nepal to make them richer by factor of 4 compared to poorest 20% in
Nepal so that the income ratio of these two groups in Nepal is the same as in Nordic countries? It
works that we have to take out 55% of income from the richest 20% people in Nepal (=(9 – 4) /
9). If we tax the richest 20% people by 55%, or in other words, take the extra income of richest
20% that is in excess to Nordic's average, then the collected tax revenue would be about Rs 103
billion (mean income of Rs 40 thousand for the richest 20% people multiplied by 4.7 million
on expenditure, however, in income basis, the inequality was even higher at 0.47 (WDI database). Hence, income based Gini would indicate even higher cost of inequality for Nepal. 16 There is another reason, why the poorest 20% in Nepal fares even worse than those in Nordic region compared to their respective 20% richest compatriots. As income from all sources in Nepal are not under government scrutiny and there is a tendency to underreport the income in surveys (especially from the richer section of the population), the income gap between the richest and poorest 20% would have been even higher than given by factor of 9.
34
20% richest people multiplied by 0.55 tax rate). The 55% is the total tax rate per capita (not per
household) that need to levy and to compute additional tax rate, we have to deduct the tax rates
that the richest 20% are paying from the 55%. As data on tax revenue by income strata are not
available in Nepal, we have no way of knowing precisely what tax rates they are paying.
Therefore we need to make a logical calculation, which is as follows.
Table 5. Income share for selected quartile population for selected countries Income share held by Canada Denmark Sweden Norway Finland India Nepal Lowest 20% 7.2 8.3 9.1 9.6 9.6 8.1 6.0 Highest 20% 39.9 35.8 36.6 37.2 36.7 45.3 54.6 Highest to lowest 20% (factor) 5.5 4.3 4.0 3.9 3.8 5.6 9.1 Source: World Bank, World Development Index (WDI) database Note: the data for all countries are for year 2000 except that for Denmark it is for 1997, for India for 2004 and for Nepal for 2003 (based on the same NLSS II data that we have used in this paper).
In 2003, the total tax revenue in Nepal was Rs 42 billion. If we assume that about half of
the tax was paid by the richest 20%, then they were contributing Rs 21 billion (in reality
however, the 20% will be paying lot less than 50% as tax system is not that progressive in
Nepal). In that case, out of would be tax revenue of Rs 103 billlion at 55% tax rate that we
computed above, we need to collect only additional of Rs 83 billion (= 103 – 21). To raise this
Rs 83 billion, the richest 20% has to be imposed additional tax rates of about 46%.17 Note that
this additional tax rate is somewhat under-rated as the richest 20% in Nepal are not paying 50%
of total tax that we made the assumption to reach at this conclusion.
With this tax rates, Nepal’s total tax in 2003 would have been, instead of Rs 42 billion,
Rs 130 billion ( = 42 + 88), which is 26% of GDP of Rs 492 billion. How does this 26% share of
tax revenue in GDP compare? It is lower to that of Norway and Denmark levels but higher than
that of Sweden and Finland. Interestingly, the share of government budget in GDP is also about
However, in Nordic countries, the income of all groups is under government scrutiny because of the well developed tax network and the data resembles the reality.
35
26%. Hence, if government was not getting foreign aid and loan, it would have to raise that much
tax to finance its budget anyway.

The dashes (-) indicate that the shares of these taxes for corresponding countries were either zeros or near zeros.
Since the purpose of this paper is not to develop a tax proposal, we restrain from detail
discussion on which taxes to use to raise this revenue (that is done in more detail in Acharya
(2008)). Here we just reiterate the fact that (1) Nepal is under-taxed (2) the role of direct tax
(income, property, capital gains and property—IPCP) is even lower creating all sort of distortion
in the country, (3) the taxes and goods and services are regressive as they are levied even on the
necessities and (4) there is too much tax on international trade (except the luxury items taxes on
other items should be minimized). With this, we argue that most of the additional tax should
come from IPCP source, and some of it from taxes on goods and services, with exception for
necessities.
We are aware that, as Sen (1999) mentions, there is a distinction between income as a
unit in which to measure inequality and income as the measure of vehicle of inequality reduction.
The income gaps must not be taken as suggestion that the corresponding income transfers would
remedy the disparities. But what this “what if” exercise tells us is that if we can make Nepal like
one of Nordic countries in terms of income distribution, we can eliminate poverty by spending
17 This is obtained by using the formula that tax rate = the additional amount that needs to be raised (Rs 88 billion) divided by the product of average per capita income of the richest 20% people (Rs 40,000) and the number of richest people (4.7 million).
36
14% of money that is collected from taxes. The additional tax money that could be raised from
this process could be used to finance development projects, education and health services and to
increase other aspects of human capabilities. Besides, there is additional benefit of this reduced
inequality; the social welfare of the country would increase by almost one-third from what is
today.
This exercise also shows that one does not need to be a socialist to ask for action in
income distribution in Nepal. Any serious economist who cares about Nepal's development
would agree that the reduction of inequality is a precondition for Nepal to take off. Even though
the tax of 55% to the richest 20% people sounds radical, this will still leave the richer in Nepal as
rich as in Nordic country compared to their respective poorer fellow-citizens. A balancing
between equity and efficiency as done by a Nordic country, a developed capitalist economy,
would allow Nepal to mobilize tremendous amount of resources, enabling it to finance the
government budget without foreign assistance, with much more equitable society. From
country's perspective we have shown that social welfare increases by reducing inequality through
strong tax system (Table 5). We also argue that despite the short run cost of taxes to them, the
richest 20% will also be better off in the long run by making contribution for building a peaceful
and prosperous Nepal.
VIII. Conclusions and Policy Recommendations
Using household level data in Nepal, we have provided a novel analysis based on the major
population groups (that are more than 1% of the total population) and their settlement regions.
This analysis will be a vital piece of information for policymakers in Nepal who are genuinely
37
concerned with tackling the poverty, stagnation, regional and ethnic, language and caste (ELC)
group disparities.
We took the minimalist approach in measuring inequalities by looking only at income (or
expenditure). Considering the coupling of poverty with other capability indicators in Nepal (the
poor being less educated, having shorter life expectancy, owning less assets and wealth), one
could easily guess that the inequalities that we have measured in the paper are underestimated.
Economic inequalities or inequalities in capabilities across regions (ELC groups) and within
region (within groups) would have been even much more intensified than recorded in this
research. However, despite this limitation in terms of measuring the magnitude of inequalities
correctly, we are convinced that the inequalities that we have measured in the paper in terms of
region, ELC groups (both within and between) alone could provide a sufficient guideline in
making right policy decisions on how to correct the inequalities and release the forces of
development in Nepal.
At first sight, the major factors of inequalities may seem like, caste and ethnicity. But
deeper analysis shows that while all these factors have sharpened the disparities, the major factor
is endowment (class) related. The class factor has intensified the disadvantages related to the
other form of disparities. Poverty is in each region and group. Inequalities, both within region
and between region and within group or between group, are alarming.
Simple calculation shows that if we can attain the direct tax rate of that of India, we
would be able to bring the people above the poverty line. In 2003, the cost of poverty elimination
in Nepalese Rupees (Rs) would be 14 billion. Using a comparable tax rate as India, on income,
profit and capital gains, Nepal could finance all the poverty gap resources. Or, if Nepal could
attain even half of the growth rates that China and India are achieving, that amount would have
38
been more than enough to address poverty. However, as we argue in the paper, to remove
poverty structurally, Nepal needs more well thought-out multi-faceted policies.
There is a debate that reducing economic inequality creates conflict with economic
efficiency, a trade-off between higher growth and more equality. For some other countries,
which have more egalitarian distribution of ownership (as in Nordic region), it could reasonable
be the case that efficiency and equity are in conflict. But in Nepal's case, looking at the rate of
growth of the Nepalese economy and the level of inequalities across groups and regions, it is
hard not to conclude that the distributional concerns are congruent with economic efficiency.
Any policy that intends to promote development in Nepal should focus on distributional aspects.
Unless Nepal addresses the poverty and massive inequalities, it will not be able to accelerate its
growth process in a noticeable way; the economy will continue to stagnate.
Economic evidence suggests that the roots of deprivation and economic inequality in a
private-ownership country like Nepal are unequal ownership of resources. Hence, any policy
measures that do not alter the distribution of resources cannot be very effective in addressing
inequalities. The damning impact of highly skewed ownership pattern is aggravated by neglect of
public education and health services. As the role of direct taxation based on income, profit,
capital gains and property is negligible, this inequality has perpetuated over time. Nepal’s
poverty and income inequalities are not the outcome of market exchange per se but the outcome
of very unequal distribution of opportunities—to use Sen's terminology—in terms of human
capabilities (income, education, health, wealth and other social opportunities).
To put Nepal in growth trajectory and in development path from the state of stagnation and
massive inequalities, Nepal needs to adopt four complimentary set of policies together and soon.
First policy recommendation is for comprehensive land reform so that the land is in the hands of
39
actual farmers. Even if there is not much land to distribute, a well-thought-out land reform
program will unleash development related positive chain effects. Once the farmers are the
owners of the land, not only would the productivity of the land increase, it will also provide
much needed positive ripple effects by boosting self-esteem of the disadvantage people and by
promoting local democracy, the two paramount conditional factors for Nepal's development.
While land is perhaps the most obvious asset to redistribute, its effects to raise standard
of living for all Nepalese would be limited. For that to realize, the distribution of land should be
accompanied by three other policies. They are (1) massive investment in decent, compulsory and
free public education till grade 10 for all school age children, (2) progressive income tax that
transfer resources from the rich to the poor and more so from unproductive investment such as
real estate to other productive investment and (3) government budgetary resource allocation in
the region in proportion to the average share of population and poor population in the region.
In this context, we argue that the policies in Nepal should follow the model of one of
Nordic countries. In doing so, the richest 20% people have to pay additional tax of 46% from
their income. Consequently, Nepal’ share of share of tax revenue in GDP would increase from
present meager level of 9% to about 26%. We recommend that this increase should come mainly
from taxes on income, profit, capital gains and property. This increase in direct taxes will
eliminate most of the distortions that are crippling Nepal's economy today, from corruption, to
massive illiteracy, to unwarranted protests, to frequent demonstrations, to disrespect for
handwork, to being a millionaire overnight by any means, to lawlessness. Moreover, by lowering
Nepal's inequality to the level of Finland, Nepal would be able to finance the above-proposed
education, health services and also raise social welfare by 33%. If we can have all four policies
together, then it will initiate a responsible government which would concentrate on how to
40
effectively use its own resources. The strong internal resource mobilization will change the
dynamics of the government; it would have to start prioritizing on which sectors to mobilize
foreign investment and how to make conducive environment for it rather than wasting time on
determining how it should be able to get more foreign aid.
In Nepal there is widespread discussion and persuasive arguments in favour of positive
discrimination in employment and other economic policies, favoring ethnic and caste groups.
However, our results suggest that the basis of economic policies should be class and endowment
based, not ELC group based. Consider some of our findings: (1) Brahman and Chhetri have the
largest number of poor, despite being the mainstream groups (2) Poor Newars are desperately
poor, not favoring better than the poor of other groups, even though Newar is the richest group in
Nepal, (3) there are massive intra-group inequalities (larger inter-group inequalities) and (4) the
past policies have systematically created regional imbalance through elite enclave and favored a
handful of rich rather than being for or against any ELC groups. The evidence of this finding is
that the richest three groups Newar, Gurung and Brahman and Chhetri have the largest
inequalities. If government were favoring any one of these three groups but not the richest, then
one should find income distribution within members of these groups more egalitarian.
These all findings suggest that positive discrimination favoring some groups is the wrong
way to address inequalities and it would be counter-productive18. If remedies are wrongly
devised, there will be regressive consequences. The target should be to uplift the downtrodden
(residing in any region and member of any ELC group) and allow them be a part of the
production process by providing them resources rather than simply focusing on caste, ethnicity
and language groups. If economic and social policies are ELC group based, there is a possibility
41
of friendly fire (terminology used by Sen (2005) for India's situation)—whereby an army is hit
by its own firing rather than by enemy shelling—and the affirmative action that was supposed to
help the downtrodden helps the affluent rather.

r rn nυ = . Note that the sub-script r can indicate both region and ELC groups that we have considered, but for exposition purpose we will indicate it for regions. Let us start with ( )0EI , with the above notations and 13 regions to consider, (7a) can be written as:
(B1) ( )13

10 lnr

⎛ ⎞= ⎜ ⎟
⎝ ⎠∑ ∑
In other words, we can compute the log deviation of each person’s expenditure from national mean and sum it over all individuals in that region to have regional ( )0EI index and then sum the regional index for all regions. By adding and subtracting natural log of regional mean, rμ , for all the 13 regions in the above equation, we will have
(B2) ( )13 13

After dividing and multiplying the first component of the right-hand side above by regional population number, , we will have

In the second component on the right-hand side, since the value of ( )ln rμ μ is the same for each person in region
r, (lnr

on the right hand sides, the measure can be written as:
