Military spending and the black market premium in developing countries

Researchers who have been concerned with the economic implications of military spending have mostly concentrated on its impact on economic growth, corruption, real exchange rate and inflation. In this paper we investigate the impact of military spending on black market premium, an area that has not been tackled so far. After adding a measure of military spending to a well established model of black market premium form the literature, we estimate the model by pooling annual data over the 1985 – 1998 period across 61 developing countries. Results from five panel specifications provide considerable evidence that higher military spending leads to higher black market premium.     

Offshoring,computerization, labor market polarization and top income inequality

This paper proposes a model of occupational choice with heterogeneous agents in terms of human capital to quantify the role of offshoring and computerization in labor market polarization and increased top income inequality. We find that both offshoring and computerization played a major role regarding labor market polarization in the US over the period 1975–2008. We further show that the last decades can be decomposed into two subperiods. Computerization is the main driver of labor market polarization from 1975 to the mid 1990s, after which globalization (through decreased costs of offshoring) explains more than 70% of job and wage polarization. Our model can also explain around 40% of the observed increase in top income inequality since 1975.     

Regional implications of financial market development: Industry location and income inequality

We develop a heterogeneous-firms model with trade in goods, labor mobility and credit constraints due to moral hazard. Mitigating financial frictions reduces the incentive of mobile workers to migrate to one region such that an unequal distribution of industrial activity becomes less likely. Hence, financial market development has opposite regional implications as trade liberalization. While the former leads to more dispersion of economic activity across space, the latter tends to drive clustering. This has immediate implications for income inequality both between regions and workers. According to our model, financial development reduces inequality in both dimensions.     

Finance,income inequality and income redistribution

Using a panel fixed effects model for a large sample of countries covering 1975–2005, we test the hypothesis that income inequality caused by finance (financial development, financial liberalization and banking crises) is related to more income redistribution than inequality caused by other factors. Our results provide evidence in support of this hypothesis. We also find that the impact of inequality on redistribution is conditioned by ethno-linguistic fractionalization. Our findings are robust to the inclusion of several control variables suggested by previous studies.     

Capitalist systems and income inequality

The paper investigates the relationship between compositional inequality (how the shares of capital and labor income vary along income distribution) and inter-personal income inequality. Using a new methodology and data from 47 countries covering the period 1995–2018, we show that higher compositional inequality is associated with higher inter-personal inequality. This is clearly shown by Latin American countries and India. Nordic countries are exceptional because they combine high compositional inequality with low inter-personal inequality. Their exceptionalism is attenuated when pension income received from largely government-mandated accumulated savings is added to capital income. The analysis shows the theoretical possibility of societies where low compositional inequality may be combined with high income inequality. Currently, China and the United States come closest to that position.     

Political regimes and income inequality

We construct a theoretically-motivated model of income inequality. Through a pooled regression on an international panel, we demonstrate that political regime (whether extractive, redistributive, or reinvestment-oriented) correlates with within-country income inequality.     

Educational opportunity and income inequality

Affordable higher education is, and has been, a key element of social policy in the United States with broad bipartisan support. Financial aid has substantially increased the number of people who complete university—generally thought to be a good thing. We show, however, that making education more affordable can increase income inequality. The mechanism that drives our results is a combination of credit constraints and the ‘signaling’ role of education first explored by Spence [Spence, A. Michael, 1973. Job Market Signalling, Quarterly Journal of Economics, 87(3) Aug., 355–374]. When borrowing for education is difficult, lack of a college education could mean that one is either of low ability or of high ability but with low financial resources. When government programs make borrowing or lower tuition more affordable, high-ability persons become educated and leave the uneducated pool, driving down the wage for unskilled workers and raising the skill premium.     

Technological progress and income inequality

Summary This paper examines the effects of Hicks-neutral, Harrod-neutral, and Solow-neutral technological improvements on the distribution of income in an overlapping generations economy with endogenous labor supply and a bequest motive. Income inequality in this model is generated by a stochastic process representing random variations in intergenerational transfers and pure luck. The comparative dynamics analysis trace the effects of the aforementioned technological changes in each and every period after they occur. These effects depend on the nature of the technological change and on the elasticity of substitution.We thank Carl Davidson, James Foster, and two anonymous referees for their useful comments.     

World income inequality and its components

About 65 percent of total income inequality in the non-communist world is accounted for by international inequality, and about 35 percent by inequality within nations. More than 70 percent of international inequality is accounted for by the inequality of two major regions.     

Estate tax and lifetime income inequality

This paper constructs a heterogeneous, intertemporal general equilibrium framework which integrates both intended and unintended bequest motives to examine the long-run effects of an estate tax on the inequality of lifetime income. The results are ambiguous in general and sensitive to the type of transfer motive involved. We find that in the purely intended bequest case, an estate tax increases the steady-state inequality of net lifetime income in the case where people's elasticity of intertemporal substitution is greater than one. However, in the purely unintended bequest case, the effect of an estate tax on inequality is dependent on the probability of survival.     

Procedural fairness and the tolerance for income inequality

This paper presents an experiment investigating what cultural and institutional factors underlying a society might render its members more or less tolerant of inequality in favor of greater efficiency. The specific institutional factors we address concern the fairness in the procedures or mechanisms through which individuals believe initial positions or roles in society are determined. Subjects' initial positions (rich vs. poor) are determined based on various criteria (random, meritocratic, arbitrary, and rewarding uncooperative behavior) and individuals' willingness to approve Pareto improvement when the improvement is mainly in favor of the already rich is measured. Our findings show that individuals' willingness to accept higher but more unequal outcomes depends on the source of the initial inequality and random assignment leads to the most tolerance for disadvantageous inequality, generating doubt about commonly held views concerning meritocracy. Moreover, holding the procedures constant, subjects reveal greater tolerance for inequality when self and the opponent share common group identity.     

Consumption,income and earnings inequality in Britain

This paper presents an analysis of the trends in inequality across income, earnings and consumption in Britain since 1978. It documents the episodic nature of inequality growth over this period largely dominated by the inequality ‘boom’ in earnings inequality of the 1980s. It builds a consistent picture across these key measures of inequality to provide a coherent link between the microeconomic and macroeconomic analysis of the evolution of inequality.     

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-uncertainty preferences and the risk premium in the exchange rate market

This paper shows that state-uncertainty preferences help to explain the observed exchange rate risk premium. In the framework of Lucas (1982) economy, state-uncertainty preferences amount to assuming that a given level of consumption will yield a higher level of utility the lower is the level of uncertainty perceived by consumers. Under these preferences we can distinguish between two factors driving the exchange rate risk premium: “macroeconomic risk” and “the risk associated with variation in the private agents' perception on the level of uncertainty”. Empirical evidence from three main European economies in the transition period to the euro provides empirical support for the model. The model is more successful in accounting for the observed currency risk premium than models with more standard preferences, and the general perception of risk by private agents is shown to be a more important determinant of risk premium than macroeconomic uncertainty.     

Import prices,income, and inequality

We compare three theoretical explanations for the positive empirical relationship between importer income per capita and traded goods prices. A first explanation is that consumers with higher incomes demand higher quality goods with higher prices. A second explanation is that wealthier people exhibit an increased willingness to pay for necessary goods as more goods enter the consumption set in a hierarchic demand system, and can thus be charged higher markups. A third explanation is that consumers with higher incomes are more finicky regarding their preferred variety in an ideal variety framework and can thus be charged higher markups. We discriminate between these three theories by focusing on the effect of income inequality on trade prices. Based on a large dataset with bilateral HS6 level data on 1260 final goods categories from more than 100 countries between 2000 and 2004, we find a highly significant negative effect of income inequality on unit values. This contradicts both the demand for quality and finickyness theories, while providing support for the increased willingness to pay theory linked to hierarchic demand. These findings on income inequality do not falsify the quality expansion model and the ideal variety model per se. However, the results do argue for place of importance of hierarchic demand.     

Entropy-based China income distributions and inequality measures

ABSTRACT

We use information theoretic information recovery methods, on a 2005 sample of household income data from the Chinese InterCensus, to estimate the income distribution for China and each of its 31 provinces and to obtain corresponding measures of income inequality. Using entropy divergence methods, we seek a probability density function solution that is as close to a uniform probability distribution of income (with the least inequality), as the data will permit. These entropy measures of income inequality reflect how the allocation and distribution systems are performing, and we show the advantages of investigating province variation in income inequality using entropy measures rather than Gini coefficients. Finally, we use a sample of data from the China Family Panel Study to recover an estimate of the 2010 and the 2016 to investigate possible directions of inequality changes using these different additional data sources, given that the 2015 Inter-Census is not yet available.     

North–South trade and income inequality

This paper investigates the effects of North–South trade on international income inequality. While empirical studies suggest that trade liberalization encourages income convergence and reduces the per capita income gap between poor and rich countries, North–South trade is shown to increase the income gap between the two regions. On the other hand, trade liberalization by either region increases the welfare of both regions, and does not necessarily reduce the gap in “real income” or utility.     

Negative income taxes,inequality and poverty

We use a neoclassical growth model with heterogeneous agents to analyze the redistributive effects of a negative income tax system, which combines a flat rate tax with a fully refundable credit (“demogrant”). We show that changing the demogrant‐to‐output ratio causes significant changes in the distribution of income. Specifically, we find that increasing the demogrant‐to‐output ratio sharply reduces the level of inequality as well as both relative and absolute poverty (all measured in terms of post‐tax total income). However, these reductions in inequality and poverty come at the expense of a significant reduction in output.
