We study the impact of endogenous longevity on optimal tax progressivity and inequality in an overlapping generations model with skill heterogeneity. Higher tax progressivity decreases both the longevity gap and net income inequality, but at the expense of lower average lifetime and lower...

Advantageous (or propitious) selection occurs when an increase in the premium of an insurance contract induces high-cost agents to quit, thereby reducing the average cost among remaining buyers. Hemenway (1990) and many subsequent contributions motivate its advent by differences in risk-aversion...

Dean Baker and Adriane Fugh-Berman have published a critique of a study I performed in 2007, entitled "Why has longevity increased more in some states than in others?ʺ One of the conclusions I drew from that study was that medical innovation accounts for a substantial portion of recent...

I show how the influences of unskilled immigration, differential fertility between immigrants and the local indigenous population, and incentives for investment in human capital combine to predict the decline of the West. In particular, indigenous low-skilled workers lose from unskilled...

This article analyzes the consequences of integration in public education. I show that the flight from the integrated multicultural public schools to private education increases private educational expenditures and, as a result, decreases fertility among more affluent parents whose children...

Our societies are witnessing a steady increase in longevity. This demographic evolution is accompanied by some convergence across countries, whereas substantial longevity inequalities persist within nations. The goal of this paper is to survey some crucial implications of changing longevity on...

This paper develops a new equilibrium model of two-sided search where agents have multiple attributes and general payoff functions. The model can be applied to several substantive issues. Here we use it to provide a novel understanding of the separate effects of equal opportunities for women in...

We demonstrate that the notion of a "family constitution" (self-enforcing, renegotiation-proof family norm) requiring adults to provide attention for elderly parents carries over from a world where sexually indifferentiated individuals reproduce by cell separation, to one where individuals...

In this paper we describe and analyse a demographic data base that has been gathered for several EU countries under a research project called AGIR. The project tries to establish facts and evidence on the ageing process in EU countries and relate this process with health and retirement issues....

This article analyzes the effect of population sorting on economic growth. The analysis is performed in a two-region growth model with endogenous fertility, in which public knowledge spillovers from the more advanced core into children’s human capital accumulation function in the periphery are...
