Abstract
This survey presents in a historical way the main contributions to the hardcore theory of aggregative games and the applications of this model to several fields of economics, other social sciences and engineering.

A game is aggregative when, for any player, payoffs depend on her own action and an aggregate that encapsulates all interactions in the game
This survey presents in a historical way the main contributions to the hardcore theory of aggregative games and the applications of this model to several fields of economics, other social sciences and engineering
I continued with my research agenda by writing a book (1996) in which aggregative games were presented as the glue unifying the diverse fields of industrial organization
Summary
A game is aggregative when, for any player, payoffs depend on her own action and an aggregate that encapsulates all interactions in the game. The theory of aggregative games focus on anonymous interactions. To predict the consequences of a shift in a parameter, I do not need to disentangle the effects on this or that strategy It suffices to focus on the aggregate. We have an additional payoff: a result obtained in the realm of aggregative games can be applied to models in different fields of economics. This point will be expanded and make more precise in Sect. We end with a section suggesting future avenues of research
