Abstract

Demichelis and Polemarchalis (2007) highlighted the role played by the frequency of trade on the degree of indeterminacy of equilibrium in economies of overlapping generations. Assuming that time has a finite starting point and extends into the infinite future, they prove that the degree of indeterminacy increases with the number of periods in the life-span of individuals, which is assumed to be deterministic. We show that this result does not hold when individual longevity is represented by an exponential survival function: the degree of indeterminacy depends on individual preferences and monetary policy but is independent of the frequency of trade.
