In this paper we study the implications of the absence of statistical arbitrage opportunities (SAO) in a two-period incomplete market economy where default is allowed but there are collateral requirements. We study the existence of state price deflators and the existence of a solution for the individual optimality problem, obtaining modified versions of the fundamental theorems of asset pricing. Then, we address the existence of equilibrium.
