What is a game?
Pages 10

A game is a mathematical instrument that serves the purpose of formalizing strategic interactions among agents, the latter being not necessarily single individuals – indeed, we will examine games where players are households, firms, public institutions, nations, etc. Uncountably many social, economic and political situations, more or less familiar to all of us, are characterized by the interplay among actors with either converging or (possibly more often) conflicting interests. This prevents them from attaining what a neutral external observer would consider as their common interest.
