Literature on monetary policy can be broadly classified into two categories. The first category involves the construction of dynamic stochastic general-equilibrium models for monetary policy. The solid micro foundations built into these models are important because they facilitate interpretation...

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...

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...

This paper studies optimal tax policy problem by employing an open economy dynamic general equilibrium model with incomplete asset markets. We investigate the possibility of welfare-improving active tax policies (under which tax rates respond to changes in productivity) on factor incomes and...

Most general equilibrium models calculate welfare gains from international risk sharing based on a loglinear approximation. They have reported welfare gains ranging from zero to one percent of permanent consumption. Some simulation results -- Tesar (1995), van Wincoop (1997), and Kim (1997) --...

This paper investigates the accuracy of the log-linear approximation method in welfare calculations, especially in measuring welfare gains of international risk sharing. We derive closed-form solutions for a two-country complete market economy using log-linearization and a nonlinear solution...
