Inequity plays a fundamental role in the evaluation of social welfare in many dimensions. We revisit the concept of inequity, whether across states of world (uncertainty), across individuals (inequality) and across generations (intergenerational equity), using a common framework generalizing the...

A transfer from a richer individual to poorer A transfer from a richer individual to poorer seems to be the most seems to be the most intuitive and straightforward way of reducing income inequality in a society. However, can such a transfer reduce the welfare of the society? We show that a rich...

In this paper, we study gains and losses that accrue to natives because of immigration. The gain on the aggregated level is called the ?immigration surplus?, which can be seen as analogous to a consumer surplus. We derive changes in the earnings of native owners of production factors by...

This paper reviews evidence on social mobility in Latin America. Several studies have used data sets that collect intergenerational socio economic information. The data, though limited, suggest that social mobility is low in the region, even when compared with low social mobility developed...

This paper compares the distributional effects of price cap and lump sum transfer policies to aid the affordability of subsistence electricity consumption. A lump sum transfer is more progressive than a comparable price cap on all units of electricity. We identify conditions under which these...

Research background: Applied welfare economics offers various social welfare functions (SWF) for appraising income distributions. Social planners commonly use two SWFs: SWFε implied by income inequality aversion (ε) and SWFv implied by rank inequality aversion (v). However, a voluntary...

In this paper, we examine the performance of the market mechanism by focusing on whether no one, in the "long-run", can be left behind with technological innovation in the economy. We show that the market mechanism with technological innovation unavoidably leaves some individuals behind. We...

In the distributive analysis, the constant relative inequality aversion utility function is a standard tool for ethical judgements of income distributions. The sole parameter ε of this function expresses a society's aversion to inequality. However, the profession has not committed to the range...

Despite the ongoing appetite of financial investors for merchant investments into the European electricity network, the EC is reluctant to approve such undertakings, thus implicitly favoring regulated investments. Based on a two-level model, we analyze the impact of profit-maximizing merchant...

Using newly comprehensive data and tools from the Global Consumption and Income Project or CGIP, covering most of the world and five decades, we present a portrait of the changing global distribution of consumption and income and discuss its implications for our understanding of inequality,...
