General dynamics in overlapping generations models

OVERLAPPING 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...

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...

Overlapping 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...

Overlapping Generations Model 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, multiplicity, positive valuation of money, and a golden rule equilibrium in which the rate of interest is equal to population growth (independent of impatience). These properties...
