In this paper, we show that within the set of stochastic three-period-lived OLG economies with productive assets (such as land), markets are necessarily sequentially incomplete, and agents in the model do not share risk optimally. We start by characterizing perfect risk sharing and find that it...

In this paper, we show that within the set of stochastic three-period-lived OLG economies with productive assets (such as land), markets are necessarily sequentially incomplete, and agents in the model do not share risk optimally. We start by characterizing perfect risk-sharing and find that it...

We document that at business cycle frequency, nominal variables, such as aggregate price levels and nominal interest rates, are more correlated across countries than real output. Since national central banks control the domestic money supply and their objective has been to keep the nominal...

One of the most well-known puzzles in international economics is the Lucas paradox: Why doesn't capital flow from rich to poor countries? Given the low capital-output ratios in developing countries, the difference in unconditional expected returns from investing there rather than in developed...

We consider a pure exchange economy repeated from a fixed endowment for an indefinite number of periods and posit a learning rule which directs convergence to competitive equilibrium. In each period trade converges to an allocation in the contract set, where agents interpret the current (common)...

We study a stochastic overlapping generations model with production and three- period-lived agents. Agents trade bonds and risky capital. Unlike the two-period model, we show that a stationary equilibrium in which prices and allocations depend solely on the aggregate capital stock and the...

This paper examines the effects of imperfect competition in unregulated electricity markets from a general equilibrium perspective, and demonstrates that horizontal market power can explain both the large peak-period price spikes observed recently in California and elsewhere, and the marked...

This paper examines an overlapping generations version of the Shapley-Shubik market game. We show existence of equilibria for the simple one commodity model and analyze the dynamics of the equilibrium trajectories generated in the model. <P> Because of the non-linearities generated by strategic...</p>
