We study the dynamics of a Lucas-tree model with finitely lived agents who "learn from experience." Individuals update expectations by Bayesian learning based on observations from their own lifetimes. In this model, the stock price exhibits stochastic boom-and-bust fluctuations around the...

The paper discusses the importance of decreasing mortality in explaining demographic change over the last century. A two-sex overlapping generations model is used where care both for children and the elderly is modeled. Assuming that the main costs of care are tied to time use (and thereby...

What is the effect of non-tradeable idiosyncratic risk on asset-market risk premiums? Constantinides and Duffie (1996) and Mankiw (1986) have shown that risk premiums will increase if the idiosyncratic shocks become more volatile during economic contractions. We add two important ingredients to...

This paper discusses a two–sector neoclassical overlapping generations economy with intermediate and final goods in the spirit of Romer (1990). The risk averse agents engage in one of two alternative occupations: either firm-ownership in the intermediate goods sector, characterized by...

We incorporate Keeping-up-with-the-Joneses (KUJ) preferences into the Blanchard-Yaari (BY) framework and develop, using an AK technology, a model of balanced growth. In this context we investigate status preference, demographic, and pension policy shocks. We find that a higher degree of KUJ...

The paper analyzes the role of governmental debt in an overlapping generations economy with stochastic production and capital accumulation. In the absence of taxation, equilibria with positive debt generically converge to debtless equilibria which are dynamically inefficient. It is shown that...

Incluye bibliografía ; Este documento estudia la dinámica de los precios de las acciones en un modelo tipo «árbol de Lucas» en el que los inversores tienen vidas finitas y aprenden de su propia experiencia. Los individuos actualizan sus expectativas mediante aprendizaje bayesiano basado en...
