In this paper, we study the decision to purchase life insurance as part of a lifecycle plan of consumption, savings, and labor supply. Households are subject to idiosyncratic risk in their labor productivity as well as the composition and size of their family, and respond by accumulating...

In this paper we examine the risk situation facing individuals in the labor market. The current consensus in the literature is that the labor income process has a large random walk component. We argue two points. First, the direct estimates of this parameter (from labor income data) appear to be...

Idiosyncratic household income is typically assumed to consist of several components. While the total income is observed and is often modelled as an integrated moving average process, individual components are not observed directly. In the literature, econometricians typically assume that...

In this paper we study the quantitative properties of alternative social security regimes in a large overlapping generations model where households face uninsurable idiosyncratic income shocks. We study this issue in two model economies. The first is the standard one characterized by exogenous...

We examine the possibility of a Pareto-improving pay-as-you-go social security system, using an ex-ante welfare criterion. Our objective is to identify the conditions under which a suitably designed pay-as-you-go social security system is welfare improving, when markets are complete and...

This paper studies the optimal trade-off between commitment and flexibility in an intertemporal consumption/savings choice model. Individuals expect to receive relevant information regarding their own situation and tastes - generating a value for flexibility - but also expect to suffer from...

In this paper, we study a household’s optimal life-cycle housing choices by calibrating a model with uninsurable labor income and house price risks. In our setup, the household not only decides between renting and owning a house, but also chooses the size of its house. Borrowing is...
