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...

This paper deals with the evolution of the "classical" growth research program of Ramsey-Cass-Koopmans vintage via its stochastic "variants" and "generalizations" (Samuelson 1976, note 1). Thus, here we trace the origins and impact of the stochastic generalization that brought about a paradigm...

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 announcement is forthcoming in Macroeconomic Dynamics. The announcement regards the creation of a new online submission and manuscript processing system for the journal, Macroeconomic Dynamics.

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>

The repeated agency model has been widely applied to a number of interesting and important problems in economics, though in many instances, the fact that the standard model generates transient dynamics limits the usefulness of the results obtained from the model for the simple reason that purely...
