Relationship Between Income Distribution And Economic Growth Economics Essay

One needs to understand the relationship between income distribution and economic growing. Developing states and least developed states are the states which suffer the most with high rates of income inequality. There is an statement that income inequality and the accretion of wealth in a little proportion of a population will in future consequence in higher growing. With this statement, the poorer people are told to be patient as they will have transportations of accumulated wealth later on through redistribution. Redistribution of wellness, with clip topographic point everybody in a better fiscal place than earlier and that is the ground why initial income inequality is acceptable. The negative side of inequality on growing is besides being argued, by a state which experiences high income inequality, has force per unit area from the hapless to redistribute the wealth accretion. To take down the rate of return on private assets, higher revenue enhancements are levied which restricts capital accretion and slows growing. These theoretical claims were supported by Alesina and Rodrik ( 1991 ) and Persson and Tabellini ( 1990 ) through cross state growing analysis.

Many statisticians and economic experts examined the relationship between income inequality and economic growing with many different consequences coming from this research. Some surveies resulted in a negative relationship between income inequality and economic growing while other surveies indicated a positive relationship. Long tally informations for developed states support Kuznets ‘ hypothesis, while surveies of 3rd universe states produced conflicting consequences. A job could be because of econometric appraisal. There are many failings in economic appraisal. First this construct relies on a cross subdivision of informations from different states where sample observations are unpredictable and one is unable to compare amongst each anticipation. Second, economic appraisal barely pays attending to traveling back into the past and working from old theoretical accounts and probes which could of hold proven theoretical backgrounds. Then looking at the short tally informations to do illations which is clip oriented. Another major issue refering this is the quality of the survey, the research and the information.

Research has been done from the 1950aa‚¬a„?s so at that place has been great research done on this subject. The information provided has become acceptable and dependable as statistics on income distribution and can be used to carry on dependable research. The safest manner to analyze this is by panel informations appraisal, which is where informations set spans over about three decennaries.

Traditional economic theory maintains that there is a possibility that income inequality may lend to economic growing for the undermentioned three concluding: the rich consume less of their income as a per centum than the hapless, ensuing in higher economy which is contributing to economic growing ; deficiency of effectual capital markets in the development states allows merely the rich to prosecute in investing activities and in conclusion a society committed to equality may further a pay policy which discourages the entrepreneurship. Empirical research worker does non supply any conclusive grounds either for a against this hypothesis. Many different theoretical accounts incorporating many different variables have been used to analyze and to find if there exists a important relation between income inequality and economic growing. Most of these theoretical accounts used assorted informations beginnings and assorted econometric techniques and we can non perchance travel over all of them, but it is deserving observing the different economic variables believed to be related to income distribution. Surveies conducted by Roberto Perotti ( 1996 ) , Robert Barro ( 2000 ) , and Roland Benabou ( 1996 ) and many others have contributed to analysis and treatments refering income distribution and economic growing. S. Anand and Kanbur ( 1993 ) showed that consequences are really sensitive to the step of inequality and the pick of informations set. Meier has reported from the World Bank informations set, that if anything, inequality in LDC in recent decennaries is associated with slower growing. A bulk of these surveies have measured this relationship with inequality as an independent variable to some discrepancy of Robert J. Barro ‘s cross-country growing theoretical account ( Forbes 2000 ) . Alesina and Rodrik ( 1994 ) examined the relationship between political relations and economic growing. They have found that income inequality and land distribution is negatively associated with subsequent growing. This consequence is related to the struggles over redistribution of productive resources. Phelan ( 2002 ) in a theoretical paper explored the issue of inequality and equity in footings of chance and consequences and concluded that finally inequality will be. Roland Benabou ( 1996 ) compiled the consequences of 23 surveies completed on associations between income inequality to growing or investing. Sum uping the information presented in these surveies, he states “ … initial inequality is damaging to long-term growing ” The empirical grounds presented in this survey indicates that a consistent one criterion divergence lessening in inequality raised the one-year growing rate of GDP per capita by.5 to.8 per centum points.

Barro ‘s ( 2000 ) empirical grounds indicates that higher inequality is likely to be a hinderance to growing in hapless states and advance growing in richer states. Along with his empirical analysis, he besides presents theoretical analysis of the macroeconomic mechanisms by which income inequality relates to economic growing. Harmonizing to him, recognition market imperfectnesss, the political economic system, sociopolitical agitation, and nest eggs rates are all interconnected between income distribution and economic growing. He has explained state of affairss where all of the mechanisms could hold either positive or negative effects on growing. The unsure consequence of all of these interconnected factors can be seen through his survey. Perotti has presented empirical grounds every bit good as analytical theories as to how income distribution, democratic establishments, and economic growing are related. He has pointed out that political instability every bit good as the education/fertility determination can besides explicate the negative relationship between income distribution and economic growing. While Perotti, Benabou, Barro and few others have found a negative relationship between income distribution and economic growing, Li and Zou ( 1998 ) and Forbes ( 2000 ) have established a positive relationship between these two macro variables.

The bulk of the empirical grounds bespeaking a important negative correlativity between income inequality and GDP growing, was compiled prior to the work of Deininger and Squire ( 1996 ) . Deininger and Squire ‘s informations set labels income distribution observations by their quality. To be acceptable in the high quality informations set, informations was required to be: based on family studies, representative of the full state ‘s population, and a comprehensive step of income, including self-employment income, non-wage net incomes, and non-monetary income ( Deininger and Squire 1998 ) . Of the 2,600 Gini coefficient observations Deininger and Squire originally complied, merely 682 met the three demands stated supra. This ‘acceptable ‘ informations set can minimise measurement mistake and any resulting coefficient prejudice and can besides increase the efficiency of estimations ( Forbes 2000 ) .

Despite the progresss made in informations aggregation and making, it is impossible to make a complete balanced informations set for the less developed states, there are spreads in the old ages of available informations for different states. To rectify this, it was deemed necessary to redevelop the information over periods of five old ages. The deficiency of consistent information for the clip periods of 1961-1965 and 1990-1995 resulted in the exclusion of these periods in the analysis. This creates 5 periods of clip: 1966-1970, 1971-1975, 1976-1980, 1981-1985, and 1986-1990. Real GDP per capita growing during these periods was the computed norm. In add-on to making a more balanced informations set ( although non wholly balanced ) ; this norm besides reduces annually consecutive correlativity associated with concern rhythms and short tally perturbations ( as pointed out by Forbes ) . This may hold some smoothing consequence on the information set. Despite such averaging during one clip period or another, the mean growing a state experienced varied greatly from growing in other states. For illustration, during the 1971-1975 clip period, Brazil experienced over a 10 % addition in existent GDP while another state, Chile, experienced a 1.12 % decrease in existent GDP per capita. The available Gini coefficients are averaged when more than one set of informations is available in one period. The human capital and market deformation statistics were provided yearly from 1960 to 1990. These statistics were besides averaged through the five twelvemonth clip periods. Certain other standards were besides applied for states to be used in this analysis. For illustration, the state must hold a per capita GDP of less than 10,000 ( US $ 1995 ) . There must besides be at least 3 clip periods where a high quality Gini coefficient was reported.

The common methods to gauge panel informations theoretical accounts are the fixed effects theoretical accounts and or the random effects theoretical account. The random effects technique can merely be used if the country-specific effects are uncorrelated with the explanatory variables ( Forbes 2000 ) . To prove this premise tungsten has conducted the typical Hausmen trial. Based on this trial, we have rejected the void hypothesis of random consequence theoretical account for this information set. So, the fixed effects theoretical account is used in our appraisal. In this model, the unseen consequence is assumed fixed over clip and hence, the difference in informations across clip can be estimated ( Wooldridge 2003 ) . Therefore, a cross-section arrested development analysis was performed utilizing the fixed effects technique with single state specific consequence. Gini coefficient ( for inequality ) , existent GDP per capita, human capital index and cost of investing ( ply ) are used in the arrested developments on the existent GDP growing.

Therefore, income inequality is the lone variable that is important with regard to existent GDP growing in both appraisal consequences. It is possible that absolute per capita income is so low compared to developed states that convergence theory is non applicable here. Similar reading could be made for the degree of instruction. In some cases the degree of instruction is below the critical degree necessary for version of newer proficient knows how to take topographic point. The coefficients for the staying independent variable are besides non statistically important. An addition in mean secondary schooling old ages for males and females additions existent GDP per capita growing. Besides, the estimation for the coefficient of the cost of investing or the market deformation is negative, as expected. To sum up, both arrested development consequences indicates that income inequality does non decelerate or halter growing in less developed states. Rather it has a positive consequence on existent economic growing, and higher coefficients of income inequality are associated with higher existent GDP growing. In a sense, it corroborates the so called “ dribble down theory ” in economic literature.


The rate of economic growing can change well between different states during the same clip period, as is apparent from the experience of the last few decennaries. Some states experience long spans of sustained increasing growing while other states stagnate at small to zero growing. This paper does non postulate that income inequality is the lone factor that affects economic growing ; nevertheless it does supply empirical grounds that there is a strong relationship between them. The grounds indicates that an addition in a state ‘s income inequality is significantly correlated with economic growing.
