Abstract

In this paper, two different mechanisms are used to study a homogeneous Cournot
duopoly in a market characterized by the downward sloping and concave price function. Two firms,
which have constant marginal costs, use adaptive, low-rationality mechanisms to adjust their produc-
tion levels toward equilibrium. In particular, the stability of the equilibrium for two different mechanisms
is studied. However, complex dynamics arise, especially when the reaction coefficient increases.
Finally, we compare the obtained results of the two models.
