Many important games are aggregative games which allows for robust comparative statics
analysis even when the games do not exhibit strategic complements or substitutes …

We enrich the theory of variational inequalities in the case of an aggregative structure by
implementing recent results obtained by using the Selten–Szidarovszky technique. We …

Various Nash equilibrium results for a broad class of aggregative games are presented. The
main ones concern equilibrium uniqueness. The setting presupposes that each player has R …

A technique due to Selten and Szidarovszky for the analysis of Nash equilibria of games
with an aggregative structure is reconsidered. Among other things it is shown that the …

We consider the equilibrium uniqueness problem for a large class of Cournot oligopolies
with convex cost functions and a proper price function p ̃ with decreasing price flexibility …

International environmental problems have played a key role in environmental economics.
Best known is probably global warming that affects all countries in the world. The effects may …
