We study an exchange economy with overlapping generations of consumers who derive utility from consuming a non-durable commodity and housing. A banking sector offers loans to finance housing. We provide a complete characterization of the equilibrium dynamics which alternates between an expansive...

This paper studies Markov Equilibria (ME) corresponding to recursive equilibria on natural state space in the stochastic OLG model extended to include non-additive utility, nonclassical production, and Markovian production shocks. Specifically, we provide sufficient conditions under which the ME...

This paper investigates a financial market in which investors with linear mean-variance preferences and multiperiod planning horizons of arbitrary finite length interact. Given heterogeneous subjective beliefs, the temporary equilibrium map determining market clearing prices is calculated...

The paper develops a large-scale overlapping generations model with production and a stochastic asset market. The role of a pension system and the impact of demographic change on real and financial markets are analyzed. In the absence of demographic change a reduction in contribution rates...

This paper studies the impact of variations of a pay-as-you-go pension system on welfare in a stochastic overlapping generations model where compulsory public retirement savings coexist with private savings in assets and bonds. It is shown that, for a stationary population, any reduction of...

This paper studies the consumption-investment problem of a consumer with a multi-period planning horizon under uncertainty. Such a setting occurs naturally in stochastic OLG models with multi-period-lived consumers. We provide a rigorous characterization of consumption-investment strategies...

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...

The paper analyzes the sustainability of governmental debt and its welfare properties in an overlapping generations economy with stochastic production and capital accumulation. In the absence of taxation, equilibria with positive debt generically converge to debtless eauilibria are typically...

This paper uncovers a novel mechanism by which bubbles crowd in capital investment. If capital is initially depressed by a binding credit constraint, injecting a bubble triggers a savings glut. Higher returns in a new bubbly equilibrium attract additional investors who expand investment at the...

The paper develops a dynamical systems approach to study asset bubbles in OLG economies with stochastic production. We derive necessary and sufficient conditions for bubbly equilibria to exist and chracterize the maximum sustainable bubble. Even if they exist, bubbles are temporary and the...
