This paper explores the extent to which markets constrain intertemporal preferences. First, we show that without transaction costs, agents are immune to exploitation in competitive markets. In particular, a sequence of trades leaving any market participant strictly worse off (termed a money...

We study a model of efficient risk sharing between two agents, A and B, who enjoy a non-durable common good. Only agent B can provide the common good whereas agent A can merely contribute indirectly by making transfers to the provider, agent B. We consider self-enforcing equilibria in the...

In this paper we investigate the effects of government budget deficit restrictions in a finite horizon model with imperfect consumer credit market. When financial markets are perfect anonymous lump-sum taxes are sufficient to achieve irrelevance of government budget deficit restrictions in the...

This paper studies Pareto e.cient income taxation in an economy with infinitely-lived individuals whose income generating abilities evolve according to a two-state Markov process. The study yields two main results. First, when individuals are risk neutral, the fraction of individuals who face a...

How far is the US social insurance system from an efficient system? We answer this question within a model where agents receive idiosyncratic, labor-productivity shocks that are privately observed. When social security and income taxation comprise the social insurance system, the maximum...

This paper studies equilibrium portfolios in the standard neoclassical growth model under uncertainty with heterogeneous agents and dynamically complete markets. Preferences are purposely restricted to be quasi-homothetic. The main source of heterogeneity across agents is due to different...

Job search is an unpleasant activity with immediate costs and delayed benefits. The tension between long-run goals and short-run impulses may lead unemployed workers to postpone repeatedly tasks necessary to find a job. In standard economic models, agents are assumed to be time-consistent, so...

We investigate risk sharing without commitment by designing an experiment to match a simple model of voluntary insurance between two agents when aggregate income is constant. Participants are matched in pairs. Each period, they receive their income with or without a random component h that one...

A vast empirical evidence in experimental psychology on time discounting has documented various behavioral anomalies which cast doubts on the empirical support for exponential discounting, to date the most widely used assumption on time preference in economic theory. The most important of such...
