We study an equilibrium model with restricted investor participation in which strategic arbitrageurs reap profits by exploiting mispricings across different trading locations.  We edogonize the asset structure as the outcome of the security design game played by the arbitrageurs.  The...

We study a model with restricted investor participation in which strategic arbitrageurs reap profits by exploiting mispricings across different market segments. We endogenize the asset structure as the outcome of a security design game played by the arbitrageurs. The equilibrium asset structure...
