This paper examines when a finitely repeated game with imperfect monitoring has a unique equilibrium outcome. This problem is nontrivial under imperfect monitoring, because uniqueness of stage game equilibrium does not guarantee such a negative result. We say an quilibrium is equilibrium...

This paper examines how the decline of communication costs between management and production facilities within firms and the decrease in trade costs of manufactured goods affect the spatial organization of a two-region economy with multi-unit-multi-plant firms. The development of information...

We investigate international negotiations on CO2 emissions reduction in the Kyoto Protocal by non-cooperative multilateral bargaining theory. The negotiation model has two phases, (i) allocating emission reductions to countries and (ii) international emissions trading. Anticipating the...

This paper provides a model to consider the conditions under which an acceptance of foreign capital is welfare enhancing in a multi-commodity multi-factor framework. Contrary to the pessimistic conventional wisdom of capital imports and welfare, we provide a justification for the acceptance of...

This paper constructs an endogenous growth New Keynesian model and considers growth and welfare effect of Taylor-type (operational) monetary policy rules. The Ramsey equilibrium and optimal operational monetary policy rule is also computed. In the calibrated model, the Ramseyoptimal volatility...

For Markovian economic models, long-run equilibria are typically identified with the stationary (invariant) distributions generated by the model. In this paper we provide new sufficient conditions for continuity in the map from parameters to these equilibria. Several existing results are shown...

We study a simple model of repeated partnerships with noisy outcomes. Two partners first choose a sharing rule, under which they start their repeated interaction. We characterize the sharing rule which supports the most efficient equilibrium, and show that it suffices to consider two particular...

We consider a repeated duopoly game where each firm privately chooses its investment in quality, and realized quality is a noisy indicator of the firm's investment. We focus on dynamic reputation equilibria, whereby consumers "discipline" a firm by switching to its rival in the case that the...

This paper proposes and implements a method to predict evolution of the crosscountry income distribution from a nonconvex growth model with unbounded productivity shocks, fitted to panel data by threshold autoregresion. We estimate the stochastic kernel of the process, and define inducively all...

This paper showed that the drop of propensity to consume in Japan during the lost decade is attributable to increase of income risks, mainly due to rises in unenployment rate/ To asses the impacts of income risks, we used the buffer stock saving model and a numerical method. The buffer stock...
