We propose a continuous-time consumption-based capital asset pricing model in which the representative agent's preferences display state-dependent risk aversion. Since fluctuations in marginal utility can be ascribed to variations in levels of risk aversion as well as in levels of consumption,...

In this note we develop a simple heterogeneous-agent model with incomplete markets to explain the prevalence of a large, low-productivity, informal sector in developing countries. In our models, taxes levied on formal sector agents are used to finance the provision of a productive public...

This paper provides an analysis of screening contracts in a complete but imperfect information environment as opposed to the usual incomplete information (Bayesian) environment. An agent faces a hold-up situation while making a cost-reducing specific investment that is not observed by the...

We examine the effects of different sequences of work and rest on the daily productivity of workers who planted trees in the province of British Columbia, Canada, comparing the intertemporal productivity profiles of planters who were paid either fixed wages or piece rates. We find that planters...

If there is asymmetry among the bidders taking part in a first price auction, the equilibrium is not expost efficient. We consider a simple model of first price auction among two bidders where resale always occurs in case of inefficiency. We obtain mathematical formulas for the equilibrium...

In this paper, we show that replacing a public-education regime by a private regime with public subsidization of education, causes agents to completely internalize the effect, on their offspring education, of their fertility decisions. As a result, fertility is lower compared to a public regime,...
