If an aggregative game satisfies the generalized Hahn conditions, then there exists a unique Nash equilibrium which may not be interior and is globally asymptotically stable under two alternative continuous adjustment processes with non-negativity constraints.

There can be three types of heterogeneity among players in a rent-seeking contest. First, effectiveness of player's effort on the winning probabilities may differ among players. Secondly, players may evaluate the rent or prize of the rent-seeking contest differently. Thirdly, players may face...

If domestic firms lobby for protection, the tariff rate is a public good to all domestic firms, whether they engage in lobbying or not. This paper analyzes how the endogenous tariff rate as a public good depends on the group size in two-stage lobbying models. The result depends not only on...

A sufficient condition is derived for the global stability of a unique interior Nash equilibrium in an aggregative game. The condition is applied to investigate the global stability of the Nash-Cournot equilibrium in Cournot oligopoly without product differentiation and that of the Nash...
