We introduce the possibility of trade in dynamic models with externalities and evaluate the consequences on the capital accumulation process, the market-clearing prices and policy making. We consider mixed economies characterized by a blend of strategic and nonstrategic sectors. An equilibrium...

In an intertemporal general equilibrium framework, we compare a Cournot equilibrium to the Walras equilibrium. The Cournot agents trade and invest less than the Walras agents. This generates an ineffciency which does not vanish as the number of Cournot agents tends to infinity. A larger number...

This paper analyzes dynamic movement of outputs and market- clearing when mutually interdependent economies trade. The equilibrium evolution of stocks admit the possibility of monotonic or cyclical behavior, even in the long run. However, the prices eventually reach a steady-state but may...
