What determines the structure of labour market institutions? This paper argues that common explanations based on rent sharing are incomplete; unions, job protection, and egalitarian pay structures may have as much to do with social insurance of otherwise uninsurable risks as with rent sharing and...

In this paper we analyse several measures which are typically included in a social security reform: a cut in the social security benefits, an increase in the social security tax and tax incentives for the purchase of private life annuities, which have recently become quite popular at the...

This study investigates the general equilibrium effects of a fertility shock under different intergenerational transfer schemes. The effects on lifetime income and utility for different generations, as well as the effects on factor prices, are analyzed in a three-period overlapping generations...

We extend "economic equivalence" results, like the Ricardian equivalence proposition, to the political sphere where policy is chosen sequentially. We derive conditions under which a policy regime (summarizing admissible policy choices in every period) and a state are "politico-economically...

We examine the dynamic interaction of the population age structure, economic dependency, and fertility, paying particular attention to the role of intergenerational transfers. In the short run, a reduction in fertility produces a “demographic dividend” that allows for higher consumption. In...

We impose a horizontal equity restriction on the problem of finding the optimal utilitarian tax mix. The horizontal equity constraint requires that individuals with the same ability have to pay the same amount of taxes regardless of their preferences for leisure. Contrary to normal findings, we...

The empirical evidence suggests that parents use inter vivos gifts (i.e., transfers of tangible and financial property) to compensate less well off children whereas post mortem bequests are divided equally among siblings. We study a theoretical model assuming, first, that the amounts given is...

As in Roemer (1982, chapter 1), this paper considers a simple international trade model and examines the existence and characterization of free trade equilibria involving the unequal exchange of labor (UE). The paper provides an almost complete characterization of the domain of economies in...

This project employs the theory of opportunity, described in Roemer''s book (Equality of Opportunity, Harvard University Press, 1998), to compute the extent to which tax-and-transfer regimes in ten countries equalize opportunities among citizens for income acquisition. Roughly speaking, equality...

This paper presents a framework for the evaluation and measurement of reversal and origin independence as separate aspects of economic mobility. We show how that evaluation depends on aversion to multi-period inequality, aversion to inter-temporal fluctuations, and aversion to future risk. We...
