Informal sector, income inequality and economic development

This paper addresses - with the help of numerical simulations - some of the issues relating to income distribution in the context of development of an economy with an informal sector and migration of both low- and high-skilled workers from the rural to the urban area. A major aim has been to see under what conditions we do or do not get an inverted U-shaped curve of income distribution. The paper finds that the tendency always is for the Gini coefficient to rise and then decline. However, once it starts declining, it need not continuously decline; it may rise, then decline, then rise again and indeed rise above the previous peak before starting to decline again and may well end at the end of the simulation at a higher value than at the start. Any case for the redistribution of income is seen to be much stronger at the later stages of development that at earlier stages, even though at later stages, Gini coefficient may be lower than at earlier stages. The policy implications of the findings are considered.     

Estimating the long-run relationship between income inequality and economic development

There are several theories describing the effect of income inequality on economic growth. These theories usually predict that there exists some optimal, steady-state growth path between inequality and development. This study uses a new measure of income distribution and panel data cointegration methods to test for the existence of such a steady-state equilibrium relation. It is shown that there is a long-run equilibrium relationship between the variables, and that this relationship is negative in developed economies.     

A credit market in early stages of economic development

Even if the relatively rich and the poor are initially caught in a poverty trap, the relatively rich can escape poverty by receiving payments from the poor. Further accumulation of wealth by the rich allows the poor to escape poverty.     

Trade, regulations, and income

We examine the relationship between openness and per-capita income using cross-country data from 126 countries. We find that trade leads to a higher standard of living in flexible economies, but not in rigid economies. Business regulation, especially on firm entry, is more important than financial development, higher education, or rule of law as a complementary policy to trade liberalization. Specifically, after controlling for the standard determinants of per-capita income, our results imply that a 1% increase in trade is associated with more than a one-half percent rise in per-capita income in economies that facilitate firm entry, but has no positive income effects in more rigid economies. The findings are consistent with Schumpeterian “creative destruction”, which highlights the importance of new business entry in economic performance, and with previous firm-level studies showing that the beneficial effects of trade liberalization come largely from an intra-sectoral reallocation of resources.     

The effect on income distribution of development,the growth rate and economic strategy

An analysis of cross-section and time series data for 83 countries confirms some, and contradicts other work on income distribution. New findings include: a dualistic socio-political system is highly unfavorable for equality. Neither the extent of government intervention in the economy nor the rate of manufactured exports are systematically related to income distribution. The analysis confirms that there is no systematic relationship between equality and the rate of economic growth. Educational participation and a reduction in the share of primary exports in GDP are both favorable for equality. There is some support for the Kuznets hypothesis that inequality increases as per capita income rises to about $400 and then declines, with further income increase, but the empirical support is not strong and may be weakening over time. These findings lead to more optimistic conclusions then other work: that rapid growth in a mixed economy is quite consistent with unchanged, or even improved, income distribution, even at early stages of development.

Corruption and economic development nexus: Variations across income levels in a non-linear framework

This article investigates the relationship between income and corruption which provides an insight to the changes in the level of perceived corruption and economic development across countries. An existing shortcoming is that previous studies have focused only on detecting the linear effects of income on corruption. We therefore use the hierarchical polynomial regression to evaluate any existence of a non-linear relationship after controlling for socio-economic and institutional factors. Our results challenge some of the findings of a negative income–corruption association in the literature, and provide some new inferences. The findings indicate a quadratic function that best fits the data, and despite an upsurge of corruption among the low-to-medium income countries, the advanced stages of development eventually reduce corruption level substantially. The results persist when per capita income is instrumented for by latitude distance and life expectancy. The policy implications suggest a combination of economic, institutional and social policies that can effectively, in turn, reduce and lower the effects of corruption on the society, economy and development.     

Trade efficiency and economic development: evidence from a cross country comparison

Economic theory suggests that development is enhanced through income growth, which is driven through increased trade. However, the empirical evidence of such a relationship most of the times is proved to be weak. In this study we try to determine the factors influencing this relationship by measuring ‘trade efficiency’. Using the data envelopment analysis (DEA) window method for a sample of 16 OECD countries, we obtained the efficiency scores and the optimal output levels for the inefficient countries for a time period of 5 years under consideration. Results drawn from the broadly used ratio analysis were also compared to the results derived from the DEA model. Our empirical findings show that ‘trade efficient’ countries have clear characteristics like low-exchange rates for exports, low R&D intensity, high-value intra industry trade and positive impact of net trade on their gross domestic product.     

Trade uncertainty,income, and democracy

Existing studies establish a strong correlation between income and democracy. Little, however, is known about whether income shocks driven by non-economic fundamentals matter for political transitions. This study employs trade uncertainty as a non-economic fundamental and examines the effect that trade uncertainty driven income variations have on democratic transitions over the period 1960–2013. We find that higher income fosters democratic transitions, but this effect works mainly for developing than developed countries. Specifically, using trade uncertainty as an instrument, we find that the Polity2 score, a measure of democracy, increases by at least 2.3 points following a 1 percentage point increase in GDP growth. This positive association is robust to exploiting conditional heteroskedasticity for identification, using different time periods, including lagged Polity2 as a regressor, and using alternative measures of GDP and democracy.     

Trade balance and income in historical perspective

This paper develops a dynamic analysis of the trade balance to investigate the roles of supply and demand shocks. It also introduces global shocks in the analysis to take into account the comovement of income across countries. The results, based on the long-run historical data and a structural VAR analysis, show that, in the U.K., Australia, Canada, and Sweden, domestic and global supply shocks, while dominant causes in long-term and cyclical changes in output, are unimportant for the trade balance. The trade balance is explained mostly by shocks that cause transitory changes in income. Transitory income shocks cause income and the trade balance to move in opposite directions in all countries except Sweden. The countercyclical behavior of the trade balance seems to be a robust feature in the U.K. and Canada but not in the smaller economies of Australia and Sweden.This research was supported by a summer research grant from the Carol Martin Gatton College of Business and Economics at the University of Kentucky.

Trade taxes and economic welfare

For a small country with no domestic distortions, trade taxes are generally viewed as welfare-reducing. This note shows that, in certain cases, a temporary trade tax may raise welfare in the present although it must lower welfare over the entire planning horizon.     

Trade,income and the Baltic Dry Index

Does trade improve the income levels of the poor and less developed nations? Focusing on the Least Developed Countries (LDCs) designated by the United Nations, we construct a new measure of trade cost, based on the Baltic Dry Index (BDI), as an instrument for trade. The BDI reflects the cost of utilizing dry bulk carriers, which are specially designed vessels for transporting primary goods internationally, where these goods dominate the output and export sectors of the LDCs. We find that a 1% expansion in trade raises GDP per capita by approximately 0.5% on average. This estimate is much larger than previously found in the literature and its quantitative significance emphasizes the importance of trade towards the economic development of low income countries.     

Trade and development policy in Mexico in the context of North American economic relations

This paper examines Mexico's trade and development policies and analyzes how these policies complement or conflict with those of the other North American nations. Looking closely at the periods 1950–1973 and 1973–1975, the authors explain how Mexico's development policies have marred or enhanced its ability to interact with the United States and Canada. They then show how the Mexico's history and strengths make it a strong candidate for partnership with Canada and the United States in a new North American Free Trade Agreement, a multilateral arrangement that will be important for continued economic prosperity in the North American region.     

Oil income shocks and economic growth in Iran

The aim of this paper is to study the relationship between oil revenue shocks and output growth in Iran by Adopting an SVAR model over the period 1959–2008. The results indicate that positive and negative oil revenue shocks significantly affect output growth positively and negatively respectively and these effects are asymmetric. While negative oil revenue shocks adversely affect the economic growth, the resource curse impedes the expected positive effects of positive oil shocks. In order to overcome the harmful effects of oil booms and busts, the establishment of oil stabilization and saving funds, diversifying economy, delinking government expenditure from oil revenues and introducing fiscal rules into the budget seems crucial for Iran economy.     

The political economy of income comparisons and economic growth

The literature on income inequality has provided various explanations as to how income inequality can affect growth, with the emphasis on ideas such as investments in human capital, issues of occupational choice, or the redistributive policies of governments. Inequality not only has a direct effect on the distribution of consumption in an economy, but it also has a powerful effect on people's subjective sense of well being. This paper takes a novel approach by focusing on the way in which a government's choice of economic policy can be influenced by how individuals perceive themselves relative to other individuals, both within the country and in foreign countries. The chosen policy affects economic growth, with the assumption being that policies that promote growth also tend to result in more switching of individuals between income groups. We show that the government's optimal policy depends on the importance of both inside country and outside country income comparisons, the fraction of national income earned by the different income groups, the potential magnitude of economic growth, the probability of switching between income groups in the presence of growth, and the relative importance of the various income groups. The model predicts that a greater degree of inside country income comparison is bad for growth whereas more outside country comparison is good for growth.     

Trade liberalization,firm entry,and income inequality

This paper examines the short‐ and long‐run effects of trade liberalization via tariff reductions on income inequality in an economy, which is characterized by an imperfectly competitive urban manufacturing sector and a perfectly competitive rural agricultural sector. Tariff reductions reduce domestic output in the importable urban manufacturing sector, leading to shifts of capital from the urban sector to the rural agricultural sector. This can narrow the wage gap between skilled and unskilled labor in the short run. However, the lowered capital cost attracts new firms, and subsequently excessive entry of firms, to the urban manufacturing sector. This firm entry effect can mitigate the favorable effect of tariff reductions on wage inequality in the long run. Empirical study confirms the findings.     

Inequality and economic growth: the role of initial income

We estimate a panel model where the relationship between inequality and GDP per capita growth depends on countries’ initial incomes. Estimates of the model show that the relationship between inequality and GDP per capita growth is significantly decreasing in countries’ initial incomes. Results from instrumental variables regressions show that in Low Income Countries transitional growth is boosted by greater income inequality. In High Income Countries inequality has a significant negative effect on transitional growth. For the median country in the world, that in the year 2015 had a PPP GDP per capita of around 10000USD, IV estimates predict that a 1 percentage point increase in the Gini coefficient decreases GDP per capita growth over a 5-year period by over 1 percentage point; the long-run effect on the level of GDP per capita is around ??5%.     

The impact of financial development,economic growth,income inequality on poverty: evidence from India

This paper examines the impact of financial development, economic growth and income inequality on poverty in India from 1970 to 2015 by employing the autoregressive distributed lag (ARDL) bounds testing procedure. The findings reveal a robust long-run relationship between financial development, economic growth, inequality and poverty. Results show that financial development and economic growth help in poverty reduction in India, whereas income inequality and inflation aggravate poverty. Empirical evidence of the Granger-causality test supports the presence of unidirectional causality from financial development and economic growth to poverty. Moreover, bidirectional causality exists between inequality and poverty. The present study provides evidence on which the policymakers may proceed with detailed investigation of how specific financial sector policies and interventions can be deployed as effective instruments for achieving favorable economic growth and income distribution. The study recommends that policies geared toward increasing financial development and economic growth should be adopted to reduce the high level of poverty and inequality currently prevailing in India.
