Davies et al. (2008, 2011) provided the first estimates of the global distribution of wealth, using 2000 as the benchmark year. These estimates have been revised and updated since 2010, and the purpose of this paper is to explain the ways in which the estimation methodology has evolved and...

This paper proposes a method for detecting income classes based on the change-point problem. There is an increasing demand for such a method in the literature. Computation of polarization indices requires a pre-grouping of the incomes. Similarly, indices of social exclusion and sometimes indices...

Given that well-being is a concave function of income, inequality is inefficient from a utilitarian perspective. This paper proposes a way to express the utilitarian benefit from redistributive reforms in terms of out- put, i.e. as a share of GDP. Three applications are presented: First, in nine...

We study how the distribution of income among members of society, and income inequality in particular, affects social willingness to pay (WTP) for environmental public goods. We find that social WTP for environmental goods increases with mean income, and decreases (increases) with income...

This paper attempts to find out the explanatory power of observed changes in the distribution of current income in explaining the relative change in aggregate consumption using the distributional approach of aggregation by Hildenbrand and Kneip (1999, 2001). The coefficients in the aggregate...

We analyze the impact of expansion of higher education on student outcomes in the context of competition among colleges which differentiate themselves horizontally by setting curricular standards. When public or economic pressures compel less selective colleges to lower their curricular demands,...

According to a standard argument, higher income inequality fosters redistributive activities of the government in favor of the median income earner. This paper shows that if redistribution is achieved by a public provision of goods and services rather than by transfers, higher income inequality...
