Governance and income inequality.
Shafique, Saima ; Haq, Rashida
INTRODUCTION
Major problems of developing countries are unequal income
distribution and low growth rate, which affect their welfare aspects. It
was implicitly assumed that whenever we achieve target of higher growth
rate, benefit of growth would automatically trickle down to the poor.
History of developing countries shows that the rich benefited more than
the poor as evidenced by rising income inequality during the period of
higher economic growth.
The economic policy changes are often triggered by the logic of low
level of equilibrium of output level, employment and income
distribution. To overcome this low level of equilibrium trap, government
often adopt polices so as to achieve high level of income and employment
growth and development, and equitable income distribution. Coherent
policy instruments are essential to meet these policy targets. Impact of
any macro economic policy has been examined by studying its impact on
economic growth and income distribution. In recent years polices have
been directed toward reducing the level of poverty and inequality
through raising quality of life in society by providing efficient and
effective governance. This new economic philosophy has resulted in a
massive change in the policy orientation of countries; the priority is
now centred on issue of governance and focus is now shifted towards a
qualitative nature of its growth and development. According to Sen
(1983), the realisation of human capabilities, that enlarge the range of
human choices, is essential for a broader notion and measure of economic
well-being. The institutional frame work is then considered as one of
the essential elements for translating growth and well-being into a
sustainable process.
The institutional/governance frame work is vital for sustainable
economic growth along with other policy factors like government polices
to allocate resources for poverty alleviating and reduce economic
inequality.
The concept of accommodating other socio-economic indicators along
with per capita income growth have taken up a significant amount of
attention, since the United Nation (1954) recommended that national
income was to be supplemented by a further set of indices, reflecting
various constitutions and determinants of aggregate development and
well-being. The studies by Adelmam and Morris (1967) also examined the
interactions among the processes of social, economic and political
change with the level and pace of economic development. Early works done
by Anderson (1964) and Aaron (1967) showed that there was an inverse
relationship between growth and income distribution. One of the
significant contributions to the quality of life with some social
indicators was proposed by Morris (1979) who constructed the physical
quality of life index and later by Dasgupta and Weale (1992). UNDP Human
Development Index had brought together the production and distribution
of commodities and expansion and use of human capabilities in their
measure. All these indices essentially focus on choices as they are
based on indicators like life expectancy, educational attainment, per
capita income, civil and property rights [Nagar and Basu (2002)]. In
some of the most cited studies show relationship between trade policy,
economic growth, poverty reduction and income distribution are probably
by Dollar (1992), Ben-David (1993), Sachs and Warner (1995), Edward
(1998), Frankel and Romar (1999), Dollar (2001) and Dollar and Kraay
(2001). Later empirical work shows that government polices aimed at
increasing economic well-being would end poverty. Le Blanc (2000)
examines the relationship between economic growth in the macro economy
and poverty and finds that this relationship is very sensitive to the
distribution features.
Now in some major studies, researchers are showing that the
differential performance level across countries is mostly because of the
quality of institutional mechanism and other policy level implementation
factors. The recent literature on governance proposes that an efficient
and effective institutional mechanism is critical in influencing growth
and well-being in to a sustainable process. The World Bank (1994)
defines good governance as the 'manner in which power is exercised
in the management of country economic and social resources. Further the
IMF (1996) in its Interim committee meeting identified promoting good
governance in all aspects that is social and economic efficiency and
growth of the countries. The UNDP (1997) report observes that result of
good governance is development that gives priority to poor, advances the
cause of women, sustains the environment and creates needed
opportunities for employment and other livelihoods. Thus we see the
concept of good governance is multifaceted and encompasses different
clement of the state and the society. Kaufmann, et al. (1999a, 1999b,
2002) indicates a strong causal relationship running from good
governance to an increasing level of per capita income and other social
outcomes. According to Rodrik (2000) the institutes would work
efficiently in which they protect private property and environment,
moderate business activity, support macroeconomic stability, provide
social insurance and protection, and manage social conflicts are the one
where economies could handle differential level of economic development
and could achieve sustainable economic advancement.
The World Development Report (2003) emphasised that for sustainable
development in a dynamic world, the institutions need to be improved at
many levels, from local to global. Moreover, the World Bank's The
Quality of Growth (2000) stressed that there are four factors especially
relevant for poverty outcomes; distribution, sustainability,
variability, and governance surrounding the growth process
Impact of different policy instruments depends on how effectively
public sector performs to achieve these objectives. This phenomenon is
also called "Good Governance". Governance means the mechanism
of decision-making process by which decision is implemented. Economists
agree that governance is one of the critical factors explaining the
divergence in performance across different countries.
The major objective of this paper is to examine the change that
occurred in economic growth and income distribution due to effectiveness
of different public polices. In addition, we show how this relationship
could have been overlooked by previous studies by introducing Sen (1974)
welfare index. Effectiveness of any public policy should be checked by
how much it helps to improve welfare of the economy. Either this
objective is achieved by increasing economic growth or improving income
distribution, so that benefit of prosperity should be enjoyed by all
segment of the economy.
METHODOLOGY
Public sector performance depends on how it effects economic growth
and income distribution of the economy that is measured by Gini
coefficient. Furthermore, different instruments which explain good
governance like Political stability, Government Effectiveness,
Regulatory quality, Rule of Law and Control of Corruption explain
cross-country variations in economic growth and income distribution of
the economy. In sensivity analysis of cross-country regression, the most
severe difficulty is in isolating the impact of Good Governance
indicators from other macro economic variables. However, the complex
interaction among Good Governance indicators and other macro economic
variables creates difficulties.
The analysis starts from the following Sen Index of welfare..
[W.sub.t] = [Y.sub.t] + [(1 - [G.sub.t]).sup.[beta]] ... (1)
Where [W.sub.t] is welfare, [Y.sub.t] is out put, and [G.sub.t] is
an index of the income distribution. Also noted that [beta] is the share
of income distribution in social welfare.
Taking natural log on both sides and differentiating with respect
to time yields the following differential equation to account for growth
process.
[??]/W = [??]/Y + ([beta])[(1 - [G.sub.t]).sup.*]/(1 - G) ... (2)
Where dots indicate instantaneous rate of change over time.
Equation (2) indicates that the growth rate of welfare [??]/W
equals the growth rate of output [??]/Y plus the growth rate of one
minus Gini coefficient [??]/G. According to the objective of our study,
we first analyse the impact of good Governance on each component of
above equation. We can then analyse the impact of good Governance on
economic growth. For convenience in empirical analysis, we specify the
following linear relationships.
[??]/Y = [a.sub.0] + [k.summation over (j=1)][b.sub.j][P.sub.j] +
[l.summation over (j=1)][c.sub.j][E.sub.i] + U ... (3)
1 - [??]/G = [[alpha].sub.0] + [k.summation over
(j=1)][[beta].sub.j][P.sub.j] + [l.summation over
(j=1)][[gamma].sub.j][E.sub.i] + V ... (4)
In Equations (3) and (4) [P.sub.j], and [E.sub.j] stands for
political and economic indicators of good Governance. In Equation (3)
[a.sub.0] measures the exogenous component of economic growth attributes
to pure exogenous progress, [b.sub.j] = (j = 1 ...... k) measures the
effect of political factors on economic growth, and [c.sub.j](j = 1
...... l) measures the effect of economic indicators on economic growth.
Like wise in Equation (4) [[alpha].sub.0] indicates the exogenous growth
in Gini coefficient that cannot be attributed to any of the variables in
equation, while [[beta].sub.j] = (j = 1 ...... k) and [[gamma].sub.j] =
(j = 1 ...... l) shows the effect of political and economic variables on
the growth rate of Gini coefficient. The variables U and V represent
random growth shocks and the random fluctuations in Gini coefficient.
Finally, model of this study is represented by Equations 2 to 4.
In order to study the impact of good Governance on economic growth
and income distribution for SARRC countries, the study chooses World
Bank "Aggregate Governance Indicators 1996-2005" dataset for
four countries; Bangladesh, India, Pakistan and Sri Lanka. The study
used different indicators of Good Governance like political and economic
indicators. In political indicators, the study uses political stability,
government effectiveness, regulatory quality, rule of law and control of
corruption and in economic indicators, government expenditure on health
and education, reserves and inflation rate.
Following, Arellano and Bond (1991), Arellano and Bover (1995),
Blundell and Bond (1997), we use system GMM method in which the levels
of instruments are used to form the moment conditions for the equation.
Specifically, if the causality problem between Governance and
social welfare were not settled before hand, the random term would be
correlated with Governance variables. This creates simultaneity bias.
Furthermore, since the inter country variation in Good Governance
indicators is much more prominent than the intra country variation, the
above mentioned correlation is mostly confined to country specific
random errors. The proposed estimation procedures handle this problem in
the following way. First, the country specific effect is eliminated in
the equation with first difference. Second, for the equations in levels
we use appropriate instrumental to tackle this problem. We follow the
second method. Given that lagged values are used as instrument in the
regression, the model (2-4) is estimated by GMM procedure, generating
consistent and efficient coefficient estimates. The use of GMM is also
called for in the light of simultaneity in our equation system 2 to 4.
EMPIRICAL RESULTS
The estimates of Equations (2-4) are presented in Tables 1 and 2.
According to the results of empirical finding, although some Good
Governance indicators improve welfare of the society but it has negative
influence on GDP growth rate. In most of the developing countries,
government face budget deficit, it has limited resources but unlimited
expenditure categories. So in which category government chooses to
increases its expenditure; either they give more importance to welfare
or GDP growth rate? Government can achieve some of objectives through
increasing its expenditure on regulatory measures like equitable income
distribution, encouraging domestic product or reducing demand for some
products. Which policy government should follow'? It depends on the
priority of the governments whether they give more weight to GDP growth
rate or achieving some other objectives, which can have ever lasting
impact on growth rate of the economy. So expenditure to improve public
institutions of any country depends on its priorities and efficiency of
the government, so in developing countries there is need of strong and
efficient government to achieve growth and welfare objective.
Mostly all expenditure increase welfare of the economy, but those
expenditures, which generate employment opportunities and have forward
linkage, influence the welfare strongly than the others. In our analysis
expenditure on regulation, and control of corruption help to improve
income distribution and output growth rate of the economy. Whenever
there is equal distribution of the income welfare of the society
improves. So there is need to have strong government that implement
polices and increase expenditure for the improving income distribution
and GDP growth rate of the economy. When GDP growth rate increase, it
shows per capita income increase, but this is not only objective of Good
Governance. There is need to transfer fruit of prosperity to all segment
of the economy and reduces trap of poverty. When government expenditure
on education and health sector increases, it improves human capital of
the economy and helps to increase employment opportunity in the economy
that in turn reduces unequal income distribution from the economy and
improves welfare of the society. As population growth rate is high in
this region of SAARC countries so when labour force participation rate
increases then income also increases because of proper utilisation of
under utilised resources of the economy and helps to increases demand
for goods and services. It also helps to increase output in the economy
because demand creates its own supply and benefit of out put goes at
gross root level. When reserves ratio increases in the economy it shows
that there are unutilised resources in the economy and effect welfare of
the economy negatively by increasing unequal income distribution.
(Reserves show that there is trade surplus and government have enough
resources to finance and help to improve output growth rate).
Whenever law and order condition improves and there is political
stability in the economy then there is favourable environment for local
and foreign investment. When investment opportunities increase it
generate employment opportunities and help to improve output growth rate
in the economy. As most of the developing countries face budget deficit
and whenever expenditure on law and order increases, it shows crowding
out of productive public expenditure and effect income growth rate
negatively but helps to improve income distribution. Political stability
and government effectiveness has strong impact on output growth rate and
to remove inequality from the economy because these factors not only
attract local investment but also foreign direct investment. But in this
specific sample, even if government sector is stable, there is still a
lot of corruption and crowding out and misutilisation of expensive
resources. This is why stable and efficient sector has no role to boost
out put growth. When out put level is low the investment is also at low
level and major problem of unemployment cannot be solved and therefore,
income distribution remains worse.
We are now in a position to derive the effects of good Governance
variables on economic welfare because some categories affect GDP growth
positively while its impact on welfare is negative and vice versa. In
order to analyse the effects of good Governance variables on economic
welfare, we substitute the estimated Equations 3 and 4 in the estimated
Equation 2. The result is presented in Table 3.
According to Table 3, we first examine the effects of good
Governance on GDP growth rate and then its effects on Gini coeffient.
Impact of regulation and control of corruption on output growth
dominate as compared to its impact on distribution of income and help to
improve welfare of the economy. Political stability helps to improve
welfare by improving income distribution of the economy. When
expenditures are diverted to improve law and order condition, there
occurs large crowding out of productive public expenditure, and welfare
of the economy decreases because our sample consists of those countries
that have limited resources and unlimited utilisation. While economic
indicators, that show condition of the governance like reserves,
government expenditure on health and education, has positive impact both
on output growth and income distribution, and helps to improve welfare
of the society.
CONCLUSION
This study is an attempt to analyse the effects of a set of Good
Governance instruments on economic welfare. The study considers both the
quantity and quality channels through which a Good Governance instrument
could affect economic welfare. The quantity channel here refers to
growth in the stock of output, while the qualitative channel means to
improve income inequality in the economy. The empirical analysis is
based on data for four SARRC countries for period 1996 to 2005. The
empirical results lead us to a number of interesting conclusions that
are discussed below.
Government sector play very important role in this specific sample
but efficiency of public sector is poor. Although resources are limited
and countries face budget deficit but still large public sector has no
strong impact to increase output which can improve the welfare of the
economy, as there is large misallocation of resources and corruption in
public sector. So the need of time is to increase efficiency of public
sector as it is possible only by increasing efficiency of public
institutions, minimising corruption and crowding out of resources.
It was commonly assumed that if government achieve objective of
output growth then it has to sacrifice welfare aspect by making income
distribution worse off and vice versa but according to empirical finding
of this paper there is positive relation between output growth and
improved income distribution of the economy. The output growth will
increase income generating activities in the economy thus reduce
unemployment rate which is major problem of developing countries. When
public sector tackles this problem then output growth and income
distribution improves in the economy. Whenever government increases its
expenditure in productive and efficient way, it achieves both objectives
side by side and increase welfare of the society.

Comments
This paper has examined the changes that occurred in economic
growth and income distribution due to effectiveness of different public
policies by using Sen (1974) welfare index. The study has used the World
Bank "Aggregate Governance Indicators 1996-2005 for four countries;
Bangladesh, India, Pakistan and Sri Lanka. The two major findings of the
study are: (1) the efficiency of public sector to increase output which
can improve the welfare of the economy is poor; and (2) there is a
positive relation between output growth and improved income distribution
of the economy. The paper argues that output growth will increase income
generating activities in the economy thus reduce unemployment rate.
However, the study has not discussed and compared the growth,
governance and inequality situation in the four above-mentioned
countries. It is therefore difficult to put the study in proper context.
It has also ignored the inter-country variations in the analysis. For
example, during the last one and half decade the relationship between
growth and income distribution in Pakistan is unclear, although it has
generally been positive, while in other countries of the refer,
relationship could be in the expected direction. This study must be
considered as an explanatory in nature requiring for further indepth
investigation.
