Any stage-game with infinite choice sets can be approximated by finite games obtained as increasingly finer discretizations of the infinite game. The subgame perfect equilibrium outcomes of the finite games converge to a limit distribution. We prove that (i) if the limit distribution is feasible...

We consider the effect of information on the average risk-free rate and the average equity premium in a standard two-period exchange economy with complete markets and a representative agent. We show that information always increases the average risk-free rate. Clearly, perfect information...

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 the movement of market-clearing prices in an intertemporal general equilibrium framework and, in particular, proves the existence of a stationary temporary equilibrium. A model of a competitive economy is developed which consists of several 'small' countries engaged in...

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 their seminal paper on the principal-agent model with moral hazard, Grossman and Hart (1983) show that the loss to the principal from being unable to observe the agent’s action is increasing in the agent’s degree of absolute risk aversion. Their proof is restricted to the case where the...

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...

This paper uses a nonlinear stochastic model to describe inflation-unemployment dynamics in the U.S. after World War II. The model is a vector autoregression with coefficients that are random walks with innovations that are arbitrarily correlated with each other and with innovations to the...
