Stackelberg versus Cournot Equilibrium

We reconsider Stackelberg’s classical critique of the Cournot duopoly, in the framework of endogenous timing for two-player games. For quantity duopoly we provide different sets of minimal conditions, directly on the demand and cost functions, yielding respectively the simultaneous and the two sequential modes of play. While our findings essentially confirm the predominance of the former, they ...

Corruption: a General Equilibrium Approach

Most theoretical studies of corruption develop micro models of individual acts while empirical papers study corruption at the country level. We build an agent-based model to provide the missing link between these two groups. Here the societal corruption level is derived from individual corruption levels optimally chosen by agents with varying risk aversion and human capital. It, in turn, affect...

Computing a Cournot Equilibrium in Integers

We give an efficient algorithm for computing a Cournot equilibrium when the producers are confined to integers, the inverse demand function is linear, and costs are quadratic. The method also establishes existence, which follows in much more generality because the problem can be modelled as a potential game.
