Abstract

In economic models, discontinuities arise when players choose the same price, location, bid or stopping time. In this chapter, we are interested by strategic games where utility functions are discontinuous. Our main objective is to present a unified theory of existence of equilibrium-like solutions. Two natural questions are explored: Under which conditions does a Nash equilibrium exist? And when it does not exist, which solution concept to use?

This is a chapter in the book:
