Several authors have implemented computer code automating the application of perturbation methods for constructing solutions for dynamic economic models.\cite{sims01,chen99,collard,schmitt,judd98,anderson02} Such techniques facilitate the construction and use of nonlinear stochastic models for...

This paper studies Tobin's proposition that inflation "greases" the wheels of the labor market. The analysis is carried out using a simple dynamic stochastic general equilibrium model with asymmetric wage adjustment costs. Optimal inflation is determined by a benevolent government that maximizes...

Various approaches to optimal monetary policy have been used to select time-invariant policy rules, including the timeless perspective approach by Woodford (1999) and the unconditional expected utility criterion of McCallum (2000). In this paper, we argue instead that policy rules should be...

This paper studies an international tax policy design problem by employing a two-country dynamic general equilibrium model with incomplete asset markets. We investigate the possibility of welfare-improving active tax policies, in particular capital and labor income tax, under the non-cooperative...

In this paper, we investigate the welfare implications of alternative financial market structures in a two-country endowment economy model. In particular, we obtain an analytic expression for the expected lifetime utility of the representative household when sovereign bonds are the only...

This paper addresses three issues on the conduct of monetary policy in open economies on the basis of a two-country model with Calvo-type sticky prices. Is the isomorphism of the optimal policy problems between closed and open economies robust to whether the foreign country is buffeted by...
