This paper provides a nontechnical introduction to the IMF's Global Economy Model (GEM). GEM is a modern dynamic stochastic general equilibrium (DSGE) model that has been designed for studying a range of issues that cannot be adequately addressed with reduced-form econometric models or an...

This paper uses a two-country version of the global economy model to investigate some costs and benefits of a small, emerging economy's abandoning a flexible exchange rate regime in favor of adopting the currency of its main trading partner. The topic is particularly relevant for countries in...

This paper develops a five-region version—Canada, a group of oil-exporting countries, the United States, emerging Asia, and Japan plus the euro area—of the global economy model encompassing production and trade of crude oil. In the presence of real adjustment costs that reduce the short- and...

Previous tests for convexity in the Phillips curve have been biased because researchers have employed filtering techniques for the nonaccelerating inflation rate of unemployment (NAIRU) that have been fundamentally inconsistent with the existence of convexity. This paper places linear and...

Data for the G-7 countries strongly support the view that economic activity has a nonlinear effect on inflation, with high levels of activity raising inflation by more than low levels decrease it. In the face of such asymmetries, the average level of output in an economy subject to demand shocks...

This paper presents empirical evidence supporting the proposition that there is a significant asymmetry in the U.S. output-inflation process. The important policy implication of this asymmetry is that it can be very costly if the economy overheats because this will necessitate a severe...

Evans (1991) has demonstrated that Blanchard's (1985) finite-horizon model obeys approximate Ricardian equivalence. This paper shows that this result is determined largely by an unrealistic assumption that labor income grows monotonically over the consumer's entire lifetime. With more realistic...
