The effect of import competition on labor income inequality through firm and worker heterogeneity in the Japanese manufacturing sector

This study estimates the effects of import competition from Asia on the labor income inequality of Japanese manufacturing workers, considering firm and worker heterogeneity. Parameters are obtained from regression results of annual salary by using constructed worker–establishment panel data. The estimated salary change is positively and negatively larger for higher- and lower-paid workers, respectively, implying that labor income inequality among industry–size–skill–gender groups has increased due to imports from Asia. However, the actual evolution of income inequality during 1998–2014 is not successfully explained by Asian imports: other shocks overshadow import competition to determine actual income inequality.     

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.     

Redistribution,inequality, and efficiency with credit constraints: Implications for South Africa

We develop a model that jointly determines the distribution of income and the aggregate macrodynamics. We identify multiple channels through which alternative public policies such as transfers, consumption and income taxes, and public investment will affect the inequality-efficiency trade-off. Income tax and transfers have both a direct income and an indirect substitution effect; a consumption tax has only the latter. We present extensive numerical simulations motivated by the South African National Development Plan 2030, the objective of which is to reduce soaring inequality and increase per capita GDP. Our results illustrate how the judicious combination of social grants and a consumption tax may help achieve these targets. The simulations also suggest that the sharp decline in the private-public capital ratio, coupled with a high degree of complementarity between public and private capital may help explain the persistence of market inequality in South Africa during the last two decades.     

Winners and losers after 25 years of transition: Decreasing wage inequality in Slovenia

Over the past twenty-five years, wage inequality has fallen in Slovenia, even as it has risen in most developed economies. The rates of return to education and work experience rose and remained high on average. However, rapid increases in the number of college graduates have outpaced the rising relative demand for skill among the youngest labor market entrants. As a result, the youngest cohorts of college graduates have experienced declining returns to education and a downward shift in their occupational distribution, which has not been experienced by older college graduates. These changes coincide with the implementation of the Bologna Reform, which reduced the length of time necessary to complete a bachelor’s degree and contributed to the incentives to attend college. Falling returns to tertiary education contributed to declining within-cohort wage inequality among the young, which was large enough to reduce overall wage inequality.     

Social norms,cooperation and inequality

This paper analyzes the outcomes that can be supported by social norms in a society of infinitely lived and patient agents that are randomly matched in pairs every period to play a given game. I find that any mutually beneficial outcome can be supported by a self-enforcing social norm under both perfect information and a simple local information system. These Folk Theorem results explain not only how social norms can provide incentives that support cooperation in a community, providing support to the concepts of social capital and corporate culture, but also how they can support inequality and discrimination.I am grateful to David Levine for invaluable guidance and ideas.

A tale of two Ginis in the US, 1921–2012

Following a methodology by Jantzen and Volpert (2012), we use IRS Adjusted Gross Income data for the US (1921–2012) to estimate two Gini indices representing inequality at the bottom and the top of the income distribution, and to calculate the overall Gini as a function of the parameters underlying the two indices. A steady increase in the overall Gini since the Second World War actually hides two different periods of distributional changes. First, the increase in inequality from the mid 1940s to the late 1970s is driven by rising inequality at the bottom of the income distribution that more than offsets a decrease in inequality at the top. The implication is that middle-income earners gained relative to high-incomes, and especially relative to low-income earners. Second, the rise in the Gini after 1981 is driven by rising inequality at the top. Third, top-driven inequality follows a U-shaped trajectory consistent with Piketty and Saez (2003, 2006). Fourth, the welfare effects of the different distributional changes behind increasing inequality can be evaluated in light of the Lorenz-dominance criterion by Atkinson (1970): we argue that the rise in inequality since 1981 is much more likely to be associated with a social welfare loss net of compensating growth.     

Agriculture reform and food crisis in Syria: Impacts on poverty and inequality

The paper pursues a twofold objective. From a methodological viewpoint it shows how to carry out an impacts evaluation of exogenous shocks on poverty and inequality in a context characterised by out-of-equilibrium, poorly-adjusting markets, as it is the case in many developing countries, using a social accounting matrix framework. From an empirical viewpoint it provides an assessment of how the cereal price spikes of 2007–2008 and the global recession of 2008–2009 have impacted the welfare of Syrian households and how did they compound with the on-going agricultural sector liberalisation implemented by the Government of Syria since mid 1990s. This will contribute to shed some lights on the economic background behind the spreading of unrest across the country over the last couple of years or so.The results show that liberalisation impacts are very different and largely affected by the adopted budget closure rules. While reforms aiming at reducing agricultural market distortions (such as production subsidies and price support for strategic crops) could generally have a positive effect on growth, poverty and inequality, the elimination of food security interventions (such as food stamp schemes) determines an adverse distributional impact against rural household and an increase of poverty. The recent macroeconomic shocks (food price crisis and the global recession) determined a generalised poverty increase and showed an income distribution bias against rural households.Three fundamental policy implications can be drawn by this study. First, the liberalisation of agricultural sector shows a significant growth potential and is likely to determine positive effects on poverty through a generalised increase of incomes as well as public budget savings that could be used for pursuing other policy goals. Second, in the short-run there is a structural trade-off between equity improvements and poverty alleviation: the policy options that will more likely reduce absolute poverty show undesirable distributive biases (both on overall inequality and on rural households vis-à-vis urban households). Third, the reform should include a careful design of the use of budget savings, mainly to address equity goals that are likely to be generated, in the short-run, by liberalisation.     

Inequality of opportunity and income inequality in nine Chinese provinces, 1989–2006

While there is a large and growing body of research describing and analyzing changes in the Chinese income distribution, researchers have paid considerable less attention to inequality of opportunity. The aim of this paper is to contribute to filling this gap in the literature. The two main questions addressed empirically for the first time in a Chinese context are: to what extent are individuals’ incomes and individual income differences due to factors beyond the individual's control (in Roemer's terminology “circumstances”) and to what extent are they due to outcomes of the individual's own choices (“effort”). What is the relationship between income inequality and inequality of opportunity?For this purpose we use data from the China Health and Nutrition Survey collected from nine provinces during the period 1989 to 2006. The CHNS has detailed information about incomes and other factors enabling us to construct a host of circumstance and effort variables for the offspring.We find that China has a substantial degree of inequality of opportunity. Parental income and parents' type of employer explain about two thirds of the total inequality of opportunity. Notably, parental education plays only a minor role implying that parental connections remain important. The results show that the increase in income inequality during the period under study largely mirrors the increase in inequality of opportunity. Thus, increased income inequality does not reflect changes in effort variables, or expressed differently, increased income inequality has not been accompanied by a decrease in inequality of opportunity.     

Does inequality help in forecasting equity premium in a panel of G7 countries?

This paper investigates whether the post-tax and transfer growth rate in the Gini index can help in forecasting the equity premium in the G7 countries (Canada, France, Germany, Italy, Japan, United Kingdom (UK), and United States (US)). To this end, we use a panel data-based predictive framework, which controls for heterogeneity, cross-sectional dependence, persistence and endogeneity. When we analyze the annual out-of-sample period of 1990–2011, given an in-sample period of 1967–1989, our results show that: (a) Time series based predictive regression models fail to beat the benchmark of historical average, except for Italy; and, (b) the panel data models beat the benchmark in a statistically significant fashion for all the seven countries. Further, our results highlight the importance of pooling information when trying to forecast excess stock returns based on a measure of inequality.     

Earnings Mobility during the Transition: The Case of Hungary

This paper tests the hypothesis that the economic transition if associated with earnings mobility that is higher than in mature market economies, and which offsets the increase in earnings inequality. It uses the Hungarian Household Panel Survey for the period 1992-1997. The paper finds that indeed five-year earnings mobility in Hungary in the early years of the transition was significantly higher than in OECD countries. However, there are sings that the mobility rate has begun to decline. The pattern of earnings mobility had a significant equalizing effect: low earners were raised up while high earners were leveled down. However, mobility was taking place against a backdrop of the fall in real wages and therefore in most cases it implied the worsening of the absolute earnings status. Unfortunately, mobility does not help much low-paid workers. In contrast to most OECD countries, in Hungary low-paid workers have little chances to move up the earnings ladder. Low-paid jobs tend to be a permanent trap rather than a stepping stone to better paid employment.
