Economic downturns,inequality, and democratic improvements

This paper explores the extent to which discrete improvements in the democratic quality of political institutions can be explained by income inequality. Empirical tests of this relationship have generally yielded null results, though typically test an unconditional relationship. Guided by a theoretical nuance of the “new economic view” of democratization and using an instrumental variable strategy, we re-examine the relationship conditional on the state of the macroeconomy. We demonstrate that the more unequal are societies, the higher the probability of experiencing democratic improvements following economic downturns. Following growth periods, higher income inequality has a slight negative or null effect on the likelihood of democratic improvement. The conditional result provides a simple explanation for why previous literature has found largely null results concerning inequality and democratization and offers additional evidence in support of the new economic view.     

Political capitalism: The interaction between income inequality,economic freedom and democracy

We study the relationship between income inequality and economic freedom for a panel of 100 countries for the 1971–2010 period. Using a panel Granger non-causality approach, we reject the null hypothesis of Granger non-causality running from income inequality to economic freedom, but not vice versa. From a series of dynamic panel estimations we show that the effect of income inequality on economic freedom is negative and robust to the inclusion of additional controls. In particular, inequality is negatively associated with those components of economic freedom related to international trade, domestic market regulation as well as the rule of law and property rights protection. We argue that the negative effect of inequality on economic freedom is due to the economic elite converting its economic power into de facto political power to defend its economic interests; these interests run counter to economic freedom, discouraging innovation and competition as well as protecting the elite's rents. Finally, we show that economic freedom decreases with income inequality even in democratic countries, suggesting that democratic institutions do not prevent economic freedom from eroding. We argue that the latter finding corresponds to a system of political capitalism or captured democracy, where a powerful economic elite can nevertheless exercise de facto political power by cooperating with politicians and other decision-makers for their mutual benefit.     

Income inequality and economic growth

Despite the extensive existing literature on income inequality and economic growth, there remains considerable disagreement on the effect of inequality on economic growth. Existing literatures find either a positive or a negative relationship. In this paper, we attempt to theoretically examine that relationship with a stochastic optimal growth model. We make the disagreement clear within a single model. We conclude (i) that both are possible – that is, higher inequality can retard growth in the early stage of economic development, and can encourage growth in a near steady state, (ii) that income redistribution by high income tax does not always reduce income inequality. Income inequality can be reduced by higher income tax in a near steady state, but it cannot be reduced in the early stage of economic development, and (iii) that two government polices – rapid economic growth and low income inequality – can be achieved by low income tax in the early stage of economic development, but both cannot be achieved simultaneously in a near steady state.     

Genetic distance,economic growth and top income shares: Evidence from OECD countries

The relationship between economic growth and income inequality remains a puzzle in the literature. The main problem has been finding a way to account for the endogeneity of growth. Using century-long data of 14 OECD countries, this study disentangles the growth–inequality relationship. In doing so, our main contribution is employing genetic and geographical distances as instruments for economic growth. The instruments are constructed on the premise that the growth of one country spills over to the others if they are connected through trade and other forms of exchange; however, the genetic and geographical distances between countries represent barriers to such spillovers. Using alternative specifications and measures, we find that growth reduces the inequality measured by top income shares. As capital share increases in the growth process and capital substitutes labour, inequality-reducing strength of growth declines. Another important finding is that the effect of growth on top income shares is more significant among the highest income groups.     

Foreign direct investment and income inequality: Does the relationship vary with absorptive capacity?

There has been little systematic empirical literature on the linkage between income inequality and FDI (Basu and Guariglia, 2007; Tsai, 1995). This paper analyzes the effects of foreign direct investment (FDI) on income inequality and asks whether the relationship depends on absorptive capacity or not, by using a cross-sectional dataset taken from 54 countries over the period 1980–2005. We adopt the endogenous threshold regression model proposed by Hansen (2000) and Caner and Hansen (2004) and find strong evidence of a two-regime split in our sample. That is, FDI is likely to be harmful to the income distribution of those host countries with low levels of absorptive capacity. By contrast, our results support the perspective that FDI has little effect on income inequality in the case of countries with better absorptive capacity. It is also shown that international trade can lead to more equal income distribution.     

Microfinance and income inequality: New macrolevel evidence

This paper addresses the empirical question of whether microfinance has any impact on income inequality at the macrolevel. Very little research has been conducted on the relationship between the macrolevel scale of microfinance and income inequality over time in a country and across countries. Based on panel‐data techniques, with annual data from 85 countries from 2001 to 2012 and a broad theoretical framework on microfinance and inequality, we provide empirical evidence that suggests that increases in the macrolevel scale of microcredit in a country contribute to reducing income inequality within that country over time. Finally, since microfinance may be endogenous, we used instruments from the existing literature to control for this problem.     

A refinement of the relationship between economic growth and income inequality

There is mixed evidence in the literature of a clear relationship between income inequality and economic growth. Most of that work has focused almost exclusively on developed economies. In what we believe to be a first effort, our emphasis is solely on developing economics, which we classify as high-income and low-income developing countries (HIDC and LIDC). We make such distinction on theoretical and empirical grounds. Empirically, the World Bank has classified developing economies in this manner since 1978. The data in our sample are also supportive of such classifications. We provide theoretical scaffolding that uses asymmetric credit constraints as a premise for separating developing economies in such a way. We find strong evidence of a negative relationship between income inequality and economic growth in LIDC to be in stark contrast with a positive inequality–growth relationship for HIDC. Both correlations are statistically significant across multiple econometric specifications. Using international data from 1960 to 2010, this article explores the effect of income inequality on economic growth using dynamic panel technique, such as system generalized method of moments (GMM) that is believed to mitigate endogenous problem. These results are strikingly contrasting to the previous estimation results of Forbes (2000) displaying significant positive correlation between two variables in the short to medium term.     

Earthquakes and terrorism: The long lasting effect of seismic shocks

The literature on the effect of shocks on civil conflicts has grown rapidly over the last decade. In this paper, we study the relationship between earthquakes and terrorism. In the short run, the destruction generated by a medium-range earthquake reduces the opportunity cost of rebelling against the government. Since destruction of infrastructures in these cases is limited, the state keeps most of its coercive capacity, which reduces the chances of full-fledged conflict but leaves open the possibility of low intensity rebellious acts such as terrorism. In the medium run the destruction of tangible assets can lead to the closing down of weak firms, the introduction of new technologies, the improvement of productivity and the increase in wealth inequality We propose a new algorithm to classify terrorism events as domestic or transnational, and show that the likelihood of a domestic terrorist event increases with the previous occurrence of an earthquake. Using earthquakes as an instrument for income, we also show that development has a positive and significant effect on the likelihood of terrorist events.     

The Evolution of Income Composition Inequality in Italy, 1989–2016

We study the evolution of inequality in income composition in terms of capital and labor income in Italy between 1989 and 2016. We document a rise in the share of capital income accruing to the bottom of the distribution, while the top of the distribution increases its share of labor income. This implies a falling degree of income composition inequality in the period considered and a weaker relationship between the functional and personal distribution of income in Italy. This result is robust to various specifications of self-employment income; nonetheless, it hinges crucially on the treatment of rental incomes. While the dynamics of imputed rents has brought about a more equitable distribution of capital incomes across the income distribution, that of actual rents has led to higher concentration of capital incomes at the top in the decade preceding the outbreak of the financial crisis. Finally, we conceptualize a rule of thumb for policy makers seeking to reduce income inequality in the long run.     

How Does Fiscal Consolidation Impact on Income Inequality?

In this paper, we assess the impact of fiscal consolidation on income inequality. Using a panel of 18 industrialized countries from 1978 to 2009, we find that income inequality significantly rises during periods of fiscal consolidation. In addition, while fiscal policy that is driven by spending cuts seems to be detrimental for income distribution, tax hikes seem to have an equalizing effect. We also show that the size of the fiscal consolidation program (in percentage of GDP) has an impact on income inequality. In particular, when consolidation plans represent a small share of GDP, the income gap widens, suggesting that the burden associated with the effort affects disproportionately households at the bottom of the income distribution. Considering the linkages between banking crises and fiscal consolidation, we find that the effect on the income gap is amplified when fiscal adjustments take place after the resolution of such financial turmoil. Similarly, fiscal consolidation programs combined with inflation are likely to increase inequality and the effects of fiscal adjustments on inequality are amplified during periods of relatively low growth. Our results also provide support for a non‐linear relationship between inequality and income and corroborate the idea that trade can promote a more equal distribution of income.     

The Evolution of the Veblenian Dichotomy: Veblen,Hamilton, Ayres,and Foster

One of the most troubling developments in recent years has been widening income inequality in the United States and elsewhere. We argue Post Keynesian Institutionalism (PKI) provides insight into the causes of increasing income inequality and our contribution is threefold. First, we compare PKI to the “financialization” literature, noting key similarities and differences. Second, we examine changes in financial structure and income inequality for a sample of developed nations, showing that financialization has increased in nearly all the countries sampled and that this increase has generally been accompanied by a rise in income inequality. Third, we demonstrate that the development of modern financial structures does not preclude an expansive welfare state and egalitarian public policies. Our finding is congruent with Hyman Minsky's conception of PKI, which stressed both that “economic systems are not natural systems” and that capitalism comes in as many varieties as Heinz has of pickles.     

Income inequality,corruption and subjective well-being

ABSTRACT

Based on the data of CGSS2013, we analyse the relationship between income inequality, corruption and subjective well being using an Ordered Probit model. Our results indicate that income inequality and corruption significantly reduces the subjective well-being of our country’s residents. Furthermore, corruption is an important channel for the negative effect of income inequality on subjective well-being, the impact of income inequality on subjective well-being is mainly achieved by the role of corruption. Specifically, the impacts vary according to hukou. Higher degree of income inequality indeed reduces the subjective well-being of urban residents, while it has a positive effect on subjective well-being of rural residents. Corruption has a significant negative impact on the subjective well-being of urban and rural residents. There is heterogeneity in the influence of different income levels in rural areas. The study in this paper shows that anti-corruption and narrowing the income gap are the two major grippers to improve the well-being of the residents.     

Income inequality and income bias in voter turnout

In the era of growing income inequality around the world, it remains inconclusive how higher income inequality affects income bias in turnout (i.e., high-income citizens vote more likely than low-income citizens). Using large-scale cross-national survey data, we show that (1) strong income bias in turnout exists in many parts of the world, (2) higher income inequality is related to lower income bias in turnout by demobilizing high-income citizens and mobilizing low-income citizens, and (3) this relationship is partly explained by the pattern that vote buying is more common in societies with higher income inequality and thus mobilizes low-income citizens but decreases political efficacy among high-income citizens. Ultimately, this study suggests that growing income inequality may not exaggerate political inequality, but may challenge the legitimacy of democratic elections.     

State‐owned Enterprises,Inequality, and Political Ideology

State‐owned enterprises continue to play a considerable role in many economies. In this study we empirically investigate the connections between these enterprises and inequality as mediated through political ideology. Using cross‐country data on the relative size of the state‐owned enterprise sector, we find strong empirical support for an inverted U‐shaped relationship between its size and income inequality. We also find strong evidence that left‐wing (vis‐a‐vis right‐wing) governments are associated with a larger state‐owned enterprise sector in countries with higher inequality. This result is robust to using cross‐sectional vs. panel data, different identification strategies, and various controls.     

PERMANENT INCOME, CONVERGENCE AND INEQUALITY AMONG COUNTRIES

The literature on inequality has generally focused on the analysis of annual per capita income. This paper adopts a different approach by considering the life-cycle dimension of inequality and convergence between economies from 1960 to 2000. We analyze the present value of the set of incomes individuals obtain throughout their whole life (permanent income). On the basis of this approach, various simulations are made to determine the effect on inequality in permanent income of variables such as survival rates and the long-run growth rates in current income. The results indicate that survival rates are an important source of inequality. Inequality in permanent income is about one third higher than in current income. The implication of this finding is that if the whole life-cycle dimension is not considered, the level of inequality among economies is being underestimated.     

Finance and inequality: a study of Indian states

Although a large literature exists on finance and economic growth, few studies have empirically examined the relationship between finance and inequality. Using grouped national household sample survey data on monthly household consumption expenditure at the sub-national level for the years 1999–2000 to 2006–2007, we examine the relationship between Financial Development (FD) and rural and urban inequality in India. The results indicate that FD is associated with a reduction in inequality, but only in the urban areas. Further, inequality is found to be higher in the richer states compared to less developed and low income states, and as state income increases, inequality also increases both in the rural and urban areas. Finally, our results show that increase in population per bank branch leads to higher inequality in urban areas but decline in rural areas.     

Brain drain and income distribution

In a context in which increased income inequality has raised much concern, and skilled workers move easily across countries, an important question arises: how does the brain drain affect income distribution in the source economy? We address this question and introduce two contributions to the literature on brain drain. First, we present and solve a simple stylized model to study whether and, if so, how the brain drain affects the distribution of income, in a context in which higher education is publicly financed with general taxes. Second, we explore empirically the effect of an increase in skilled emigration on income distribution. A key prediction of our theoretical model is the existence of a non-monotonic relationship between income inequality and emigration of skilled workers. Our empirical data confirm this result, showing a statistically significant inverse U-shaped form.     

富爸爸、穷爸爸和子代收入差距

本文使用基于工具变量分位数回归的分解方法,通过构建低收入家庭子女与高收入家庭子女拥有相同的特征分布情况下的反事实收入分布,对高、低收入家庭子女的收入差距进行分解。结果显示,高、低收入家庭的子女之间的收入差距主要来源于教育水平、工作经验、工作单位性质等特征差异;两组子女间的回报差异存在,但主要影响低分位点处子女之间的收入差距,对高分位点处的收入差距影响有限。高分位点处子女之间的收入差距几乎能够完全被特征差异所解释。     

Income, income inequality, and health: Evidence from China

This paper tests using survey data from China whether individual health is associated with income and community-level income inequality. Although poor health and high inequality are key features of many developing countries, most of the earlier literature has drawn on data from developed countries in studying the association between the two. We find that self-reported health status increases with per capita income, but at a decreasing rate. Controlling for per capita income, we find an inverted-U association between self-reported health status and income inequality, which suggests that high inequality in a community poses threats to health. We also find that high inequality increases the probability of health-compromising behavior such as smoking and alcohol consumption. Most of our findings are robust to different measures of health status and income inequality. Journal of Comparative Economics 34 (4) (2006) 668–693.     

Monopolistic supply of sorting,inequality, and welfare

Why is an increase in income inequality often accompanied by an increase in socioeconomic segregation? And what are the welfare implications of this comovement? This paper uses a theoretical model to analyze the relationship between income inequality and socioeconomic segregation. It shows that rising inequality can trigger sorting according to income, as a monopolist's profits from offering sorting increase with income inequality. It also examines the relationship between sorting and social welfare and shows that profit-maximizing sorting patterns are not necessarily optimal from a welfare perspective. In fact, for a broad field of income distributions (monopolist) profits increase with inequality, while at the same time total welfare from sorting decreases.
