We develop a optimal rules-based interpretation of the 'three pillars macroeconomic policy framework': a combination of a freely floating exchange rate, an explicit target for inflation, and a mechanism than ensures a stable government debt-GDP ratio around a specified long run. We show how such...

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 uses the IMF's Global Integrated Monetary and Fiscal Model to compute shortrun multipliers of fiscal stimulus measures and long-run crowding-out effects of higher debt. Multipliers of two-year stimulus range from 0.2 to 2.2 depending on the fiscal instrument, the extent of monetary...

The paper assesses, using seven structural models used heavily by policymaking institutions, the effectiveness of temporary fiscal stimulus. Models can, more easily than empirical studies, account for differences between fiscal instruments, for differences between structural characteristics of...

This paper updates existing measures of the U.S. fiscal gap to include federal laws up to and including the mid-December 2010 federal fiscal stimulus. It then applies the methodology of generational accounting to establish how the burden of adjustment required to attain fiscal sustainability is...

The Global Integrated Monetary and Fiscal model (GIMF) is a multi-region, forward-looking, DSGE model developed by the Economic Modeling Division of the IMF for policy analysis and international economic research. Using a 5-region version of the GIMF, this paper illustrates the model’s...

The output effects of 2009 fiscal expansions have been hotly debated. But the discussion of fiscal multipliers is even more relevant now that several European countries have had to quickly retract their stimulus measures in an effort to regain market confidence. Using regime-switching VARs we...

The paper evaluates the costs and benefits of fiscal consolidation using simulations based on the IMFs global DSGE model GIMF. Over the longer run, well-targeted permanent reductions in budget deficits lead to a considerable increase in both the growth rate and the level of output. The gains may...
