Abstract
- This is a continuation of the earlier work of Matsumoto and Szidarovszky (2010A) that compares Bertrand and Cournot equilibria in a differentiated n-firm oligopoly from static and dynamic points of view. It is, among others, found that both equilibria can be locally unstable if the firms naively forms expectations and the number of the firms are strictly more than three. The main purpose of this paper provides economic circumstances under which such unstable equilibria can be stabilized. Three main results have been shown. First, the equilibria can be locally stable if the dynamic system with adaptive expectations or the dynamic system with adaptive adjustments is adopted. Second, these two dynamic systems are equivalent as far as the local stability is concerned. Third, the total output under the dynamic system with naive expectations exhibits a period-2 cycle.
