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...

This paper develops a theory of international currency portfolios that holds in general equilibrium, and that is therefore not subject to the criticisms directed at the portfolio balance literature of the 1980s. It shows that, under plausible assumptions about fiscal policy, the relationship...

This paper uses two of the IMF’s DSGE models to simulate the benefits of international fiscal and macroprudential policy coordination. The key argument is that these two policies are similar in that, unlike monetary policy, they have long-run effects on the level of GDP that need to be...

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...

We study the welfare properties of an economy where both monetary and fiscal policy follow simple rules, and where a subset of agents is borrowing constrained. The optimized fiscal rule is far more aggressive than automatic stabilizers, and stabilizes the income of borrowingconstrained agents,...

Several emerging economies have, until recently, experienced large government surpluses and accelerating foreign exchange reserve accumulation. This has been accompanied by economic booms, exchange rate appreciations and in some cases increases in domestic inflation. We show that one way to...

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...

Is aggressive monetary policy response to inflation feasible in countries that suffer from fiscal dominance? We find that if nominal interest rates are allowed to respond to government debt, even aggressive rules that satisfy the Taylor principle can produce unique equilibria. However, resulting...

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...
