Numerical Simulation of the Overlapping Generations Models with Indeterminacy
In this paper we explore the computation and simulation of stochastic overlapping generation (OLG) models. To do so we compute all Markovian equilibria adopting a recently developed numerical algorithm. Among the models we studied, the indeterminacy in deterministic OLG model results in many different equilibrium paths corresponding to the initial condition that all asymptotically converge to t...
متن کاملIndeterminacy of Stationary Equilibrium in Stochastic Overlapping Generations Models*
In this paper, we consider the local uniqueness properties of stationary rational expectations equilibria (REE) in a stochastic overlapping generations (OLG) model. It is known that in non-stochastic OLG models, steady-state equilibria are locally isolated, although there may exist indeterminate non-stationary perfect foresight equilibria. We show by construction that in the stochastic model, e...
متن کاملIndeterminacy and Asset Price Volatility in Stochastic Overlapping Generations Models∗
This paper addresses the e ects of indeterminacy on the volatility of asset prices in a stochastic overlapping generations model with 3-period lived agents. With complete markets, indeterminacy is characterized by the initial conditions and all equilibria converge to one of the deterministic steady states in the long run. With incomplete markets, the degree of indeterminacy is countably innite....
متن کاملOverlapping Generations Models
The specific feature of the Overlapping Generations Model is that new cohorts are born in every period, live for a number of periods and die. Consequently, at any point in time, society is composed of individuals belonging to the different generations that are currently alive. Because of the demographic structure of the population, no trade involving individuals about to die is possible and hen...
متن کاملOverlapping Generations Models with Immigration
In this work we develop overlapping generations models (OLG) which explicitly include immigration. In the following, we propose two general equilibrium models. In a first approach, we investigate the effect of a sudden variation in the number of immigrants on the host country to shed light on the welfare effects of immigration for the various generations of the host country’s population. Subseq...
