This paper provides sufficient (as well as necessary) conditions for the integral of a correspondence defined on a measure space with atoms to exhibit star-shaped values. This result is used to analyse the existence of a Nash equilibrium in games with a meaure space of agents with atoms and of a competitive equilibrium in economies with mixed markets. In either cases, it is shown that an exact equilibrium exists whenever atoms are "small enough".

Abstract
This paper provides sufficient (as well as necessary) conditions for the integral of a correspondence defined on a measure space with atoms to exhibit star-shaped values. This result is used to analyse the existence of a Nash equilibrium in games with a meaure space of agents with atoms and of a competitive equilibrium in economies with mixed markets. In either cases, it is shown that an exact equilibrium exists whenever atoms are "small enough".File in questo prodotto:
