This working paper presents a comprehensive overview of the theoretical structure of the Global Integrated Monetary and Fiscal Model (GIMF), a multi-region dynamic general equilibrium model that is used by the IMF for a variety of tasks including policy analysis, risk analysis, and surveillance

This paper analyzes the scope for systematic rules-based fiscal activism in open economies. Relative to a balanced budget rule, automatic stabilizers significantly improve welfare. But they minimize fiscal instrument volatility rather than business cycle volatility. A more aggressively...

Using data on long-term interest rates for 17 industrial countries, this paper develops some simple measures of monetary policy credibility and then tests if such measures improve the out-of-sample forecasts of conventional models of the inflation-unemployment process. The results provide some...

Using stochastic simulations and stability analysis, the paper compares how different monetary rules perform in a moderately nonlinear model with a time-varying nonaccelerating-inflation-rate-of-unemployment (NAIRU). Rules that perform well in linear models but implicitly embody backward-looking...

Stochastic simulations are employed to compare performance of monetary policy rules in linear and nonlinear variants of a small macro model with NAIRU uncertainity under different assumptions about the way inflation expectations are formed. Cases in which policy credibility is ignored or treated...

We estimate the respective contributions of institutions, geography, and trade in determining cross-country income levels using recently developed instruments for institutions and trade. Our results indicate that the quality of institutions ""trumps"" everything else. Controlling for...
