This paper examines the empirical relation between employment protection regulation and gross job flows in a sample of developed and developing countries. By implementing a difference in difference test we avoid the potentially severe endogeneity and omitted variable problems associated with...

The goal of this paper is to determine the effects of different social security regimes on job search. A less generous pension system induces higher savings across the life cycle and makes agents wealthier and thus more reluctant to accept low wage offers. On the other hand, as the social...

We study a model with a durable good subject to abrupt, periodic obsolescence, and characterize the optimal purchasing policy. Consumers optimally synchronize new purchases with the arrival of new durable models. Hence, some agents use a "flexible" optimal replacement rule that switches between...

This paper presents a model developed to explain the life-cycle patterns in both homeownership and portfolio allocation, and the relationship between them, using a model of rational agents. Two key innovations are incorporated into this model. First, housing is explicitly modeled as both a...

Mortgages are one-sided contracts under which the borrower may terminate the contract at any time, while the lender must commit to honoring the terms of the contract throughout its life. There are two aspects to this feature of the contract that are modeled in this paper. The first is that the...

This paper examines the optimal (first-best) fiscal policy in a stochastic representative agent model that exhibits a ``keeping up with the Joneses'' utility function and imperfectly competitive product markets. We find that the optimal labor tax is a constant, whose sign is determined by the...

This paper introduces a tractable, structural model of subjective beliefs. Since agents that plan for the future care about expected future utility flows, current felicity can be increased by believing that better outcomes are more likely. On the other hand, expectations that are biased towards...

In this paper, we analyze the strength and nature of bequest motives in the United States using data from the 2000 Health and Retirement Study (HRS). The results of our analysis suggest that bequest motives are very strong in the United States and that they are altruistically motivated. This...

The purpose of this paper is to examine whether the stock wealth effect of consumption exhibits structural change(s) or behaves asymmetrically over business cycles. We first perform a general test of linearity for the behavior of aggregate consumption in response to changes in stock wealth based...

We study empirically how close consumption-smoothing models employing present-value relationships fit data for Latin-American countries, either in an open-economy or closed-economy environment. Bivariate VARS are estimated using either individual-system or a joint-system techniques (OLS or GLS -...
