Does microfinance affect income inequality?

This study addresses the question whether participation of the poor in microfinance contributes to reducing a country’s level of income inequality. Using data from 70 developing countries, we show that higher levels of microfinance participation are indeed associated with a reduction of the income gap between rich and poor people. We also show, however, that the effects of microfinance on reducing income inequality are relatively small. The results of this study add to the discussion on the impact of microfinance on poverty by showing that, although access to microfinance does seem to improve the relative income position of the poor, this improvement is modest, which is probably because the use of microfinance is generally small as compared to the size of the economy of the countries in our sample. Microfinance should, therefore, not be seen as a panacea for bringing down income inequality in a significant way.     

Does unconventional monetary policy affect inequality? Evidence from Japan

Inequality has been largely ignored in the literature and practice of monetary policy, but is gaining more attention recently. Here, we exclusively focus on the impact of unconventional monetary policy (UMP) on inequality. We look at how the recent UMP in Japan affected inequality, using household survey data. Our vector auto regression (VAR) results show that UMP widened income inequality after 2008Q3 as the Bank of Japan (BoJ) resumed its zero-interest rate policy and reinstated UMP. This is largely due to the portfolio channel. To the best of our knowledge, this is the first study to empirically analyse the distributional impact of UMP. Japan’s extensive experience with UMP may hold important policy implications for other countries.     

Does wealth inequality affect the transmission of monetary policy?

We provide evidence that higher wealth inequality between households is associated with stronger real effects of monetary policy. First, we use state-dependent local projections to show that the US and the UK exhibited stronger real effects of monetary policy in times of higher wealth inequality. Second, we measure wealth inequality within US states and document that economic activity responds more strongly to interest rate changes in states where wealth is distributed more unequally. Third, we show that ECB monetary policy has stronger real effects in Euro Area countries with higher wealth inequality.     

How can robots affect wage inequality?

We explain the simultaneous presence of i) increasing per capita output, ii) declining real wages of low-skilled workers, and iii) a rising wage premium of higher education within a model of economic growth in the age of automation. The theoretical implications are consistent with the data for the United States since the 1970s. Thus, automation contributes towards our understanding of the driving forces of rising inequality. The immediate policy conclusion is that investments in higher education can help to soften the negative effects of automation.     

Does consumption inequality track income inequality in Italy?

This paper presents stylized facts on labor supply, income, consumption, wealth, and several measures of consumption and income inequality drawn from the 1980–2006 Survey of Household Income and Wealth (SHIW) conducted by the Bank of Italy. The SHIW provides information on consumption, income and wealth, and a sizable panel component that allows econometricians to estimate sophisticated income, consumption, and wealth processes and to analyze labor market and portfolio transitions. We find that over the sample period income inequality is higher and has grown faster than consumption inequality. Most of the increase in income inequality is related to an increase in the degree of earnings' instability rather than to shifts in the wage structure. We suggest that, in particular, the labor market reforms of the 1990s and 2000s are the most plausible explanation of the increased earnings inequality.     

Does energy‐related aid affect emissions? Evidence from a global dataset

Donor countries have been using international aid in the field of energy for at least three decades. The stated objective of this policy is to reduce emissions and promote sustainable development in the global South. In spite of the widespread use of this policy tool, very little is known about its effect on emissions. In this paper we perform an empirical audit of the effectiveness of energy‐related aid in tackling CO₂ and SO₂ emissions. Using a global panel dataset covering 128 countries over the period 1971–2011 and estimating a parsimonious model using the Anderson and Hsiao estimator, we do not find any evidence of a systematic effect of energy‐related aid on emissions. We also find that the non‐effect is not conditional on institutional quality or level of income. Countries located in Europe and Central Asia do better than others in utilizing this aid to reduce CO₂ emissions. Our results are robust after controlling for the environmental Kuznets curve, country fixed effects, country‐specific trends, and time‐varying common shocks.     

Does development aid increase military expenditure?

Using a new instrumental variable strategy, we examine whether bilateral development aid increases military expenditure in recipient countries. The instrument is the interaction of donor government fractionalization and the probability of receiving aid. The dataset includes new data on military expenditure for 124 recipient countries over the 1975–2012 period. When accounting for outliers, our results do not suggest that development aid affects military expenditure in the full sample. However, the effect of aid on military expenditure varies across characteristics of recipient and donor countries, even after excluding outliers. First, aid increases military expenditure in countries that depend on aid and are prone to conflicts. Second, aid provided by coordinated market economies increases military expenditure.     

Does income inequality increase charitable giving?

Do households react to changes in the distribution of income in their localities by changing their charitable giving? The theoretical prediction of the effects of income inequality on giving is unclear. We study how changes in income inequality measured at the neighbourhood and municipality levels affect charitable giving by households in Canada between 1991 and 2006. We find that increases in inequality increase giving. Results are sensitive to the geographic dispersion of low‐ and high‐income households in neighbourhoods within a municipality. The effect on donations is smaller in areas with high levels of inequality at both neighbourhood and municipality levels.     

Does supervisor gender affect wages?

This paper uses data from the National Longitudinal Survey of Youth, 1979 (NLSY79) and the Current Population Survey to estimate the wage effects of having a female supervisor. Existing studies, using OLS to estimate the supervisor gender effect, find wage penalties for both men and women associated with working for a female supervisor. We extend this research in two important ways. First, we control for gender segregation at job level as opposed to the broader occupation level. This is important because of the concern that supervisor gender is simply a proxy for the gender-type of the job. Second, we apply fixed effects estimation to control for selection effects of supervisor gender. When using OLS we find estimates of the supervisor gender effect similar to those in the existing literature. However, when using fixed effects we find no evidence of a supervisor gender effect for women and only a small, marginally significant effect for men. We conclude that existing OLS estimates overstate the importance of the impact of supervisor gender on wages.     

Does medicaid generosity affect household income?

Almost all recent literature on Medicaid and labor supply has used Affordable Care Act (ACA)-induced Medicaid eligibility expansions in various states as natural experiments. Estimated effects on employment and earnings differ widely due to differences in the scope of eligibility expansion across states and are potentially subject to biases due to policy endogeneity. Using a Regression Kink Design (RKD) framework, this paper takes a new approach to the identification of the effect of Medicaid generosity on household income. Both state-level data and March CPS data from 1980 to 2013 suggest that generous federal funding of state-level Medicaid costs have a negative effect on household income. The negative impact of Medicaid generosity on household income is more pronounced at the lower end of the household income distribution and on the income and earnings of female heads.     

Does income inequality increase marginal propensity to consume?

This article empirically investigates the effects of income inequality on the marginal propensity to consume (MPC), using panel data of 22 OECD countries over the period 1994–2015. We find that MPC increases dramatically as income inequality increases. In subsample analyses, the MPC of a high inequality group is more than twice that of a low inequality group.     

Does income inequality really matter for credit booms?

This paper addresses the question whether income inequality is associated with credit booms, alongside other macroeconomic factors. We distinguish between the different types of credit booms—real estate credit booms, household credit booms, firm credit booms and credit booms that turn into crises. Furthermore, our analysis of a sample of 70 countries between 1990 and 2016 does not provide any evidence of credit booms driving income inequality. We observe that capital inflows increase the likelihood of credit boom occurrence, while countries experiencing high economic growth tend to have more credit booms. Finally, we note that credit booms are more frequent in countries with fixed exchange rate regimes.     

Does capital-based regulation affect bank pricing policy?

Does privatization of daycare affect maternal employment?

This article is the first attempt to examine the privatization effects of daycare centres on the employment of mothers with preschool children. Analysing newly constructed municipality-level data for 2000, 2005 and 2010 in Japan, the results suggest that an increased proportion of private daycare centres has positive effects on mothers’ labour force participation, and the effects are large for municipalities in Tokyo metropolitan area.     

Does international mobility of high-skilled workers aggravate between-country inequality?

This paper analyzes the interaction of international migration of high-skilled labor and relative wage income between source and destination economies of expatriates. We develop an overlapping-generations model with increasing returns which suggests that international integration of the market for skilled labor aggravates between-country inequality by harming those which are source economies to begin with while benefiting host economies. The result is robust to allowing governments to optimally adjust productivity-enhancing investments which could potentially attenuate brain drain. Optimal public investment tends to decrease in response to higher emigration.     

Revisiting the democracy-private investment nexus: Does inequality matter?

Contrary to the predictions of a large theoretical literature, recent cross-country evidence suggests autocracies can generate statistically indistinguishable levels of private investment compared to democracies. We argue that the previous exclusion of inequality explains part of this puzzle. We model current investment as a function of investors’ beliefs about future tax rates, which are conditioned by the constraints on the Executive in setting tax rates and expropriating tax revenues. In democracies, where tax rates reflect the preferences of the median voter, investment declines with rising inequality. In autocracies, investor beliefs about future tax rates reflect the relative power of Elites compared to the Executive. As inequality rises, the increased resources available to Elites constrains the Executive’s ability to expropriate more tax revenues. The heterogeneous determinants of investor beliefs can explain the observed pattern of investment across regime types. We first test our predictions at the macro-level with cross-country data. We then test the behavioral underpinnings of our model with a novel laboratory experiment showing how inequality affects individual-level investment behavior dependent upon regime type. Results from both types of analyses show that when inequality is taken into account autocracies can generate similar levels of investment to democracies.     

Terrorism and spatial disparities: Does interregional inequality matter?

This article examines the relationship between interregional inequality and the incidence of domestic terrorism in a panel of 48 countries over the period 1990–2010. The results show that a high level of interregional inequality increases the number of domestic terror events in the sample countries. This finding is robust to the inclusion of additional explanatory variables that may affect both interregional inequality and domestic terrorism. Furthermore, the observed link between interregional inequality and terrorist activity does not depend on the choice of the specific measure used to quantify the degree of dispersion in the regional distribution of GDP per capita within the sample countries.     

Does government ideology affect personal happiness? A test

We investigate the impact of government ideology on left-wing as compared to conservative individuals. We find that conservative people are happier, on average. In a sample excluding the richest countries left-wing people are happier under the tenure of left-wing governments.     

Trust and attitudes toward income inequality: Does individualism matter?

In the last decade authors have increasingly examined the role of two cultural traits – trust and individualism – on a variety of economic outcomes ranging from gendered attitudes to entrepreneurship, human capital accumulation, and economic development. While both have positive effects, recent literature suggests that the effects of trust are often conditional on other variables, and this aspect has been neglected in the literature. Indeed, a recent paper found that with respect to gendered attitudes, there are important interactions between the traits of trust and individualism. Building on this foundation we explore how views of trust and individualism interact to affect attitudes about income inequality. Our results show that while views regarding social trust generally positively affect the desire for income equality, this effect is strengthened in the presence of high individualism. Alternatively stated, distrust in highly individualistic environments leads to a greater desire for income differences (inequality). Our result highlights the important role played by market-based price and profit incentives in fostering economic activity and exchange in larger, impersonal extended orders where interpersonal trust and reputational effects are generally absent (in contrast to personal, small group exchange). Our results are robust to a variety of techniques to establish identification and account for sample selection and omitted variable bias.
