Overlapping 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...
متن کاملOVERLAPPING GENERATIONS MODELS OF GENERAL EQUILIBRIUM By
The OLG model of Allais and Samuelson retains the methodological assumptions of agent optimization and market clearing from the Arrow-Debreu model, yet its equilibrium set has different properties: Pareto inefficiency, indeterminacy, positive valuation of money, and a golden rule equilibrium in which the rate of interest is equal to population growth (independent of impatience). These propertie...
متن کاملEliminating sunspot effects in overlapping generations models
We reappraise the robustness of sunspot effects in overlapping-generations models. Azariadis’s wellknown example economies have stationary, deterministic fundamentals (preferences, technologies, and endowments), yet sunspots affect multiple equilibria. And those equilibria are robust to common perturbations of underlying fundamentals. However, we find that judiciously splitting each of Azariadi...
متن کاملMoney and Market Incompleteness in Overlapping Generations Models
This paper investigates the extent to which the character of equilibria in stochastic overlapping generations models stems from the model’s generic market incompleteness. In addition, it addresses the question of whether money serves to complete markets in these models. We show that money does not complete markets in the sense of expanding the set of state-contingent commodities that an individ...
