Over the past two years, the IMF staff has been developing a new multicountry macroeconomic model called the Global Economy Model (GEM). This paper explains why such a model is needed, how GEM differs from its predecessor model, and how the new features of the model can improve the IMF’s...

We develop a theory-based model of equilibrium exchange rates incorporating factors that have been found to matter empirically. The model provides insights into how variables should be measured and what are appropriate cross-country restrictions. We estimate this model using a panel of 12...

This paper presents simulations with a multicountry structural model to show that worldwide expansionary fiscal policy combined with accommodative monetary policy can have significant multiplier effects on the world economy. It also provides a framework for assessing the effects of fiscal...

U.S. household consumption declined sharply in late 2008, marking a departure from the trend of a steady increase in U.S. consumption as a share of income since the 1980s. Combining econometric and simulation analysis, we estimate that this departure will be sustained beyond the crisis: the U.S....

International financial integration has greatly increased the scope for changes in a country''s net foreign asset position through the valuation channel, namely capital gains and losses on external assets and liabilities. We examine this valuation channel in a dynamic equilibrium portfolio model...

We revisit the time-honored link between productivity and the real exchange rate. Consistent with the traditional view, we find that higher labor productivity tends to lead to appreciation of the real exchange rate. Contrary to the traditional view, however, we find that the positive...

As part of this mandate, since the mid-1990s the IMF Consultative Group on Exchange Rate Issues (CGER) has provided exchange rate assessments for a number of advanced economies from a multilateral perspective, with the aim of informing the country-specific analysis of the IMF's Article IV staff...

Using survey data of market expectations, we ask which popular exchange rate models appear to be consistent with expectation formation of market forecasters. Exchange rate expectations are found to be correlated with inflation differentials and productivity differentials, indicating that the...

The sizable hoarding of international reserves by several East Asian countries has been frequently attributed to a modern version of monetary mercantilism-hoarding international reserves in order to improve competitiveness. From a long-run perspective, manufacturing exporters in East Asia...
