We study the international monetary policy design problem within an optimizing two-country sticky price model, where each country faces a short run tradeoff between output and inflation. The model is sufficiently tractable to solve analytically. We find that in the Nash equilibrium, the policy...

The objectives of this paper are: first, to quantify the stabilization welfare gains from commitment; second, to examine how commitment to an optimal rule can be sustained as an equilibrium and third, to find a simple interest rate rule that closely approximates the optimal commitment one. We...

This paper compares two contrasting approaches to robust monetary policy design. The first developed by Hansen and Sargent (2003, 2007) assumes unstructured model uncertainty and uses a minimax robustness criterion to design monetary rules. This contrasts with an older literature that structures...

We describe some of the main features of the recent vintage macroeconomic models used for monetary policy evaluation. We point to some of the key differences with respect to the earlier generation of macro models, and highlight the insights for policy that these new frameworks have to offer. Our...

We develop a general mandate framework for delegating monetary policy to an instrument-independent, but goal-dependent central bank. The goal of the mandate consists of: (i) a simple quadratic a loss function that penalizes deviations from target macroeconomic variables; (ii) a form of a...

This chapter develops a dynamic general equilibrium model that is intended to help clarify the role of credit market frictions in business fluctuations, from both a qualitative and a quantitative standpoint. The model is a synthesis of the leading approaches in the literature. In particular, the...

This paper shows that uncertainty about an emerging market's international reserves can affect the willingness of foreign investors to supply international credits. We illustrate the relevance of this concern for South Korea. Uncertainty has asymmetric effects. When the expected reserve position...
