Does wealth inequality reduce the gains from trade?

This paper refines and tests the hypothesis that the impact of opening to trade on a country’s economic growth is affected by the inequality of its distribution of wealth. Analysis of panel data on 44 developing countries between 1960 and 2000 suggests that the difference in growth rates between the period an economy is open and the period it is closed depends inversely on the degree of wealth inequality prior to opening. There is evidence to suggest that access to credit and lack thereof may lie behind these results, thus highlighting a new aspect of the role of financial development.     

Does inequality in health impede economic growth?

This paper investigates the effects of inequality in health on economic growth in low and middle income countries. The empirical part of the paper uses an original cross-national panel data set covering 62 low and middle income countries over the period 1985 to 2007. I find a substantial and relatively robust negative effect of health inequality on income levels and income growth controlling for life expectancy, country and time fixed-effects and a large number of other effects that have been shown to matter for growth. The effect also holds if health inequality is instrumented to circumvent a potential problem of reverse causality. Hence, reducing inequality in the access to health care and to health-related information can make a substantial contribution to economic growth.     

Does income affect fertility or does fertility affect income?

"This paper tests for the dynamic causal connection between real income per capita and the birth rate for a subset of developing countries. These countries are Costa Rica, El Salvador, Guatemala, Mexico, and Uruguay. Our empirical findings show that, for the historical period under review, in several countries real income per capita affected the birth rate. Virtually no evidence is found to support the hypothesis that the birth rate affected real income per capita."     

Does microcredit reduce the gender gap in employment? Evidence from Egypt

In Egypt, there is a remarkable gap between men's and women's participation in the labour market. In this study, we examine the impact of microcredit on the labour supply of men and women and subsequently investigate whether microcredit can reduce the employment gap between men and women in Egypt. We find a negative effect of microcredit on men's employment, but a positive effect on the employment of women. Borrowing from a microcredit source increases the probability of women working by 8.5 percentage points and mainly affects self‐employed work. We also find a positive effect of microcredit on work in small businesses. This finding suggests that women can use microcredit to open small shops or household businesses. Finally, using decomposition analysis, we find that microcredit reduces the overall employment gap between men and women by 0.743%.     

Does school shutdown increase inequality in academic performance? Evidence from COVID-19 pandemic in China

The school shutdown due to the global pandemic of coronavirus disease 2019 (COVID-19) can lead to an increase in educational inequality through disproportionately affecting disadvantaged children. We use data from a unique survey of 7202 junior high school students and their parents from Shaanxi province to explore whether the school shutdown enlarged the educational gap between students with different parental socioeconomic statuses (SES) during the pandemic. We find that students with more highly educated parents experienced an increase in relative test rankings after the shutdown period. A 1-year increase in parents' education led to a relative 0.18-percentile increase in students' rankings of total test scores. We also identify the mechanisms behind the enlarged gap by means of heterogeneity analyses. We show that parents' education mainly affected children's academic performance through parents' engagement in their children's homeschooling, mitigating the negative impacts of Internet addiction on students, and serving as substitutes for teachers who were unable to teach well online.     

The role of public pensions in income inequality among elderly households in China 1988–2013

Using data from the Chinese Household Income Project surveys for 1988, 1995, 2002 and 2013, we investigate the role of public pensions in income inequality among households with elderly members across two decades of pension policy reforms. We examine the distribution and role of public pensions at a national level and analyse the evolution of the contribution of public pensions to national income inequality across a much more extended time period than earlier studies, which have generally focused on regional changes over short periods. Our findings suggest that public pensions have become the most important source of income for households with elderly members on average in China, but the distribution of pension income is highly unequal, with a Gini coefficient of 0.74 in 2013. Public pension income has been the largest source of income inequality for elderly households since 2002 and contributed to more than half of total income inequality in the most recent year of the survey. This finding is robust against variations in the income inequality measures used. Additionally, our analysis suggests unequal distribution of pension benefits is the primary driver of pensioners' income inequality. Among several hypothetical policy changes, ensuring a minimum pension benefit for all existing pensioners seems to be the most fiscally effective option in reducing income inequality, with a 0.8% reduction in the Gini coefficient for a 1% increase in public pension expenditure.     

Is there income mobility in the Philippines?

Despite a more robust economic performance over the past decade compared with the 1980s and 1990s, growth in average household income is still far below what might be expected given the pace of economic expansion in the Philippines. Inequality of household income has also remained high, which leads to the question: is there income mobility in the Philippines? Using longitudinal data from three years of the redesigned Philippine Family Income and Expenditure Survey (2003, 2006, and 2009) and a variety of analytical tools, we examine the mobility of Filipino household income and show that it is less stagnant than is conventionally perceived. Empirical evidence suggests that significant positive and negative mobility exists; albeit, the two tend to offset each other, contributing to slow household income growth at the aggregate level. In addition, there is some evidence that transitory fluctuations contribute significantly to the observed level of income mobility. Overall, the findings are robust across different analytical tools used in measuring income mobility.     

Does crop insurance reduce pesticide usage? Evidence from China

We test how crop insurance participation affects the intensity of pesticide use in China using data on staple crop production from eight provinces. Our preferred specification instruments farmers' decisions of participation in insurance by village-level intensities of promotional activities and controls for province fixed effects. We find crop insurance participation significantly reduces pesticide use intensity. The reduction effect is greater for smaller plots, older farmers, and farmers who are more risk averse.     

Brain drain in the age of mass migration: Does relative inequality explain migrant selectivity?

Brain drain is a core economic policy problem for many developing countries today. Does relative inequality in source and destination countries influence the brain-drain phenomenon? We explore human capital selectivity during the period 1820–1909.We apply age heaping techniques to measure human capital selectivity of international migrants. In a sample of 52 source and five destination countries we find selective migration determined by relative anthropometric inequality in source and destination countries. Other inequality measures confirm this. The results remain robust in OLS and Arellano–Bond approaches. We confirm the Roy–Borjas model of migrant self-selection. Moreover, we find that countries like Germany and UK experienced a small positive effect, because the less educated emigrated in larger numbers.     

Can trade liberalisation in South Africa reduce poverty and inequality while boosting economic growth? Macro–micro reflections

South Africa is trapped in a cycle of modest growth, unacceptable poverty levels and record unemployment. This has led to renewed interest on the relationship between macro (growth) and micro (poverty and distribution) issues. This paper uses a macro–micro tool that couples a computable general equilibrium model with microsimulation models to examine the impact of further unilateral trade policy reforms on growth, poverty and welfare. Trade liberalisation alone has very minimal short-run macroeconomic consequences while its long-term impacts are positive and magnified by technical factor productivity (TFP) effects. Trade liberalisation has no appreciable impact on poverty in the short run even if we allow for trade-induced TFP increases. In the long run, however, poverty reduces even in the case when we do not allow for TFP increases. Trade liberalisation policy has been found to be progressive despite the low level of tariff protection remaining in South Africa.     

Does government health insurance reduce job lock and job push?

I study job lock and job push, twin phenomena believed to be partially due to employment-contingent health insurance (ECHI). Using variation in Medicaid eligibility among household members of male workers to identify changes in those workers' reliance on ECHI, I estimate notable job lock and job push effects. For married male workers, a 15 percentage point increase in the likelihood a household member is eligible for Medicaid increases the rate of voluntary job exits over a four-month period by 14%. For job push, the same increase in a household member's likelihood of Medicaid eligibility reduces the transition rate into jobs with ECHI among all male workers by 8%.     

When did inequality rise in Britain and America?

New information and new perspectives reveal three long periods in which the two most-studied economies had a widening in income and wealth gaps. First, income inequality rose in both Britain and America between 1977 and 1995. In America, it regained the old pre-1929 levels, contrary to the official figures. Second, wealth and earnings gaps widened sometime in America between 1774 and 1913. Third, inequality rose in Britain from 1740 to 1810, earlier than others have suspected. This early widening reflects the role of severe relative price movements, which have been missed by the usual measures of (nominal) income inequality.     

Does polycentric spatial structure narrow the urban-rural income gap? – Evidence from six urban clusters in China

As urbanization and economic development continue to accelerate, social equity issues are becoming increasingly prominent and the urban–rural income gap is an important manifestation of this. This study uses the data of urban clusters from 2010 to 2019 and focuses on the relationship between the polycentric spatial structure of urban clusters and the urban–rural income gap. The findings show that the development of urban cluster polycentricity can reduce the urban–rural income gap, and the higher the degree of polycentricity in morphology, the smaller the gap. However, the relationship between polycentric spatial structure and the urban–rural income gap is “U” shaped, indicating the need for rational planning of urban polycentric development patterns rather than simple expansion. In addition, the polycentric spatial structure of urban clusters can reduce regional disparities by promoting factor mobility and industrial structure optimization. However, this depends on the level of industrial development and infrastructure. This study highlights the importance of a balanced approach to urban development that takes into account regional disparities and issues of social equity.     

What happened to regional inequality in Britain in the twentieth century?

New estimates of regional GDP for Great Britain in the twentieth century differ from those of Crafts but confirm his hypothesis of a U‐shaped regional inequality curve between 1911 and 2001. Comparison of these estimates with revised estimates for 1861–1911 suggests that the decline in inequality in the first half of the twentieth century forms part of a trend of declining regional inequality and catch‐up of the poorer regions with the richest (the South East) dating back to the 1860s at least. This convergence trend was interrupted by the First World War and the subsequent difficulties of Outer Britain in the 1920s when the gap between the South East and the rest widened. However, sometime after 1931 it picked up again. Since 1971 inequality has worsened and catch‐up has stopped; indeed, there has been divergence of the South East from the rest. This divergence has been especially marked since 1991. Although growth for all regions was faster during the period of increasing regional inequality that encompasses the second half of the twentieth century, the golden age of economic growth for regions outside the South East occurred during the long boom following the Second World War.     

Does foreign direct investment promote regional development in developed countries? A Markov chain approach for US states

This paper investigates the effects of inward FDI on per capita income and growth of the US states since the mid-1970s. Using a Markov chain approach, it shows that both quantitative and qualitative characteristics of FDI affect per capita income and growth. The empirical findings suggest that employment-intensive FDI, concentrated in richer states, has been conducive to income growth, while capital-intensive FDI, concentrated in poorer states, has not. Consequently, FDI has tended to be associated with weaker rather than stronger income convergence among US states. It appears to be less important whether FDI has been undertaken in the manufacturing sector of US states or in other sectors.     

Climatic impact on China's residential electricity consumption: Does the income level matter?

It is widely accepted that energy use contributes to climate change. However, climate change can also affect energy demand. There is ample proof in the literature that a feedback phenomenon exists. However, empirical evidence of its mechanism and operation in different contexts is missing. As China is the largest consumer of electricity worldwide, a detailed study of its energy consumption patterns would be insightful. Moreover, how the increasing income of Chinese residents affects the climate sensitivity of electricity demand is particularly relevant. Using data from 278 cities in China over the period 2005 to 2015, this study applies a newly developed technique, partially linear functional-coefficient panel data model, which enables disclosure of the role of income levels. The results indicate that climate change significantly stimulates residential electricity consumption in hot weather rather than in cold weather. Additionally, the level of income affects climate sensitivity. Specifically, an increase in income initially increases the marginal effect of cooling degree days (days on which building cooling is desired) on electricity consumption, but the curve of the marginal increment becomes flat as income growth increases further.     

Income inequality and happiness: Which inequalities matter in China?

The effect of inequality on happiness should intrigue social scientists. Of the many dimensions of income inequality, we explore four, analysing a rich data set for China. Does actual or perceived inequality have a greater effect on happiness? We find that perceptions of inequality are the more important. How broad is the reference group with which people compare themselves? They report that it is narrow; and indeed narrowly defined inequality has the greater effect on happiness. Do perceptions of the degree of fairness of inequality matter? They do, as they ameliorate the adverse effect of inequality on happiness, especially for the poorest. Is it self-centred or community-based inequality which affects happiness? Both measures have significant effects, but in opposite directions. The research and policy implications are discussed.     

Do innovation dimensions matter in China’s cross-regional income differences?

This paper studies the interlinks between innovation inputs and outputs and between innovation outputs and economic development. Using a panel data-set from 31 regions of China, we show that the difference in regional innovation output can be significantly explained by R&D manpower and expenditure, highly educated students, and public education spending, while GDP is linked to patent, high-tech export share, and new product sales. Our findings provide support for the use of government R&D subsidies and education rebate.
