老龄化对我国农村消费和收入不平等的影响

本文从生命周期理论框架出发,考察了我国农村消费及收入不平等与年龄及人口老龄化之间的关系。我们采用CHIP 1988年、1995年和2002年三年的微观数据,利用方差分解和回归分解方法,将我国农村总的消费和收入不平等分解为出生组间不平等、出生组内不平等和老龄化效应。结果发现,在我国农村,消费不平等要低于收入不平等;其次,在各个时期,组内不平等都占主导地位;最后,老龄化对不平等的效应很小。     

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.     

Expected work experience and the gender wage gap: A new human capital measure

Work experience is a key variable in earnings function estimates and wage gap decompositions. Because data on actual work experience are rare, studies commonly use proxies, such as potential experience. But potential experience is identical for all individuals of the same age and level of education, so it ignores labor market intermittency because of childbirth and child rearing—a critical omission when analyzing gender differences in earnings. This paper constructs a better proxy: expected work experience, which is the sum of the annual probabilities that an individual worked in the past. This measure can be generated using commonly available data on labor force participation rates by age and gender to gauge the probability of past work. Applying the measure to labor force survey data from the Philippines shows that conventional proxies underestimate the contribution of gender differences in work experience in explaining the gender wage gap.     

Ethnic fragmentation,public good provision and inequality in India, 1988–2012

We study how ethnic fragmentation in Indian districts influences the distribution of consumption, both overall and between social groups. In the absence of systematic evidence on inequality between social groups (horizontal inequality) during the sample period, we construct estimates of horizontal and overall inequality, and find that horizontal inequality is a small proportion of overall inequality, as well as that both overall and horizontal inequality have increased over time. Our empirical results indicate that more fragmented districts have higher inequality, but the relationship between fragmentation and horizontal inequality is weak. Additionally, we show that fragmentation increases inequality by lowering public good provision.     

The effects of free trade agreements on regional wages in China

We empirically study the effects of free trade agreements on regional wages in China using Redding and Venables’ (2004) extended model and manufacturing firm-level data in China from 2000 to 2007. We show that although free trade agreements can, in general, increase firms’ average wage level, they also contribute to increasing the wage gap in China. We also find that free trade agreements can have different effects on firms’ wages across China. In particular, they have stronger effects on average wage levels in land border regions than in coastal regions. Moreover, although firms in land border regions may be located closer to the partner countries of free trade agreements, they may still prefer to use shipping to transport goods. Our findings have important policy implications. In particular, we suggest that free trade agreements with China’s western neighbors should be accompanied by the development of appropriate land transportation networks. Moreover, income tax policy regimes should be differentiated across regions in China.     

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.     

Holdup and wage dispersion

This paper provides a search-theoretic model of the labor market, in which large firms hire workers sequentially and wages are bargained with full commitment. The firm's optimal vacancy-posting strategy trades off the fact that a larger size decreases marginal benefits from subsequent jobs, but avoids higher future recruiting costs attributable to the holdup effect. The holdup effect is dominant if the production function is not sufficiently concave, resulting in firm-size wage premium. The equilibrium features wage dispersion both within and between firms. When calibrated to the U.S. data, the extended model accounts for 67%–84% of the observed wage dispersion, among which 13%–27% is attributed to the holdup effect.     

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.     

Unemployment and the business cycle in a small open economy: G.M.M. estimation and testing with French data

What is a relevant model for the European business cycle? In this paper, the empirical performances of three models are compared: a canonical Walrasian R.B.C. framework, its extension to the case of a small open economy, and a version of this model with search and wage bargaining on the labor market. Structural parameters of the models are estimated using G.M.M. and their abilities to reproduce the French business cycle, taken as representative of the European business cycle, are tested. Only the small open economy with unemployment is able to generate theoretical moments that match their empirical counterparts.
