A Note on Aoki-Yoshikawa Model
(Published in Reconstructing Macroeconomics)
Abstract
In this paper, we explore a dynamical version of the Aoki and Yoshikawa model (AYM) for an economy driven by demand. We show that when an appropriate Markovian dynamics is taken into account, AYM has different equilibrium distributions depending on the form of transition probabilities. In the version of the dynamic AYM presented here, transition probabilities depend on a parameter c tuning the choice of a new sector for workers leaving their sector. The solution of Aoki and Yoshikawa is recovered only in the case c = 0. All the other possible cases give different equilibrium probability distributions, including the Bose-Einstein distribution.Paper submitted to the special issue “Reconstructing Macroeconomics”
