With varying aptitudes in different occupations, individuals typically maximize income by specializing in one occupation which promises the highest income. Due to numerous labor market imperfections and uncertainties, the choice of best occupation is accomplished with only partial success. We...

Neither income, consumption, nor wealth is an "ideal" tax base, or one that plausibly identifies what one really should want to tax. Rather, they are best justified as imperfect stand-ins for some underlying (but unobservable) metric of inequality that may be relevant to distributive justice...

This paper studies how wealth and health inequalities have interacted with the Covid-19 epidemic in a way that has reinforced inequalities in income, savings, epidemic risk and even individual preventive behaviors. We present in more detail two papers and their theoretical and empirical results....

A utilitarian social planner who maximizes social welfare assigns the available income to those who are most efficient in converting income into utility. However, when individuals are concerned about their income falling behind the incomes of others, the optimal income distribution under...

This paper combines cross-sectional and longitudinal income data to present the evolution of absolute intergenerational income mobility in ten developed economies in the 20th century. Absolute mobility decreased during the second half of the 20th century in all these countries. Increasing income...

This paper combines historical cross-sectional and longitudinal data in the US to study patterns of economic growth within the income distribution. We quantify absolute mobility as the fraction of families with higher income over a period of several years. The rates of absolute mobility over...

When individuals’ utility is a convex combination of their income and their concern at having a low relative income (the weights attached to income and to the concern at having a low relative income sum up to one), the maximization of aggregate utility yields an equal income distribution. This...
