A new proof for the existence of Nash equilibrium

Theoretical Economics 2023-10-04 v1

Abstract

We present a new proof for the existence of a Nash equilibrium, which involves no fixed point theorem. The self-contained proof consists of two parts. The first part introduces the notions of root function and pre-equilibrium. The second part shows the existence of pre-equilibria and Nash equilibria.
