Inequality of Income and Consumption in the U.S.: Measuring the Trends in Inequality from 1984 to 2011 for the Same Individuals

This paper examines the distribution of income and consumption in the U.S. using one dataset that obtains measures of both income and consumption from the same set of individuals. We develop a set of inequality measures that show the increase in inequality during the past 27 years using the 1984–2011 Consumer Expenditure Survey. We find that the trends in income and consumption inequality are similar between 1984 and 2006, and diverge during and after the Great Recession. For the entire 27‐year period we find that consumption inequality increases almost as much as does income inequality.     

Changes in the Income Distribution of the Dutch Elderly between 1989 and 2020: a Dynamic Microsimulation

This paper analyzes the income distribution of the Dutch elderly using a microsimulation model. Microsimulation models allow for detailed estimates of the income distribution. Our model deviates from traditional models by explicitly considering the persistency and heteroskedasticity of real income shocks. In this way, modeling all underlying processes influencing household income becomes less necessary, which can improve the trade‐off between refinement and tractability of microsimulation models. We show the results of three model specifications with different levels of refinement. The results are in line and indicate that between 2008 and 2020, the highest predicted annual growth among the elderly is for median‐income households (about 1.2 percent). High‐income households have a somewhat lower predicted growth (about 1.0 percent) and low‐income households only have a predicted annual growth of 0.5 percent. Inequality therefore seems to increase in the lower part of the distribution, while it will probably decline in the upper part of the distribution.     

Understanding Changes in the Distribution and Redistribution of Income: A Unifying Decomposition Framework

In recent decades income inequality has increased in many developed countries but the role of tax and transfer reforms is often poorly understood. We propose a new method allowing for the decomposition of historical changes in income distribution and redistribution measures into: (i) the immediate effect of tax‐transfer policy reforms in the absence of behavioral responses; (ii) the effect of labor supply responses induced by these reforms; and (iii) a third component allowing us to explore the effect of changes in the distribution of a wide range of determinants, including the effect of employment changes not induced by policy reforms. The application of the decomposition to Australia reveals that the direct effect of tax‐transfer policy reforms accounts for half of the observed increase in income inequality between 1999 and 2008, while the increased dispersion of wages and capital incomes also played an important role.     

Natural Disasters and Participation in Volunteer Activities: A Case Study of the Great Hanshin‐Awaji Earthquake

The Great Hanshin‐Awaji (Kobe) earthquake in 1995 has had a significant detrimental effect on the economic conditions of southern‐central Japan. However, the earthquake also led people to acknowledge the importance of the many volunteer activities in Japan at that time. Using a large sample of individual‐level data from 1991 and 1996, this study investigates how and the extent to which the earthquake increased the participation of students and house‐workers in volunteer activities. After controlling for various individual characteristics, a Heckman‐Tobit model was used and the following key findings were obtained: (1) the probability of students’ participating in volunteer activities was 2% higher after the earthquake than before, and (2) the number of days that students spent participating in volunteer activities was 4.38 days longer after the earthquake than before. However, the same did not hold true for house‐workers.     

效率与公平兼顾的最优所得税:理论框架及最优税率估计

最优所得税主要探讨税收如何兼顾公平与效率问题,以及给定公平偏好程度下,如何确定最优边际税率水平。即使在崇尚罗尔斯社会福利函数的社会里,政府同时兼顾再分配和财政收入目标的基础上,只要略加考虑税收对劳动供给的效应,哪怕是微弱的考虑和兼顾,最高边际税率都不会达到100%。而且,借鉴斯特恩最优线性所得税模型及美国个人所得税制度,估计我国现行个人所得税最高边际税率还可以适当降低到36%左右。
