Using a general-equilibrium simulation model featuring nominal rigidities and monopolistic competition in product and labor markets, this paper estimates the macroeconomic benefits and international spillovers of an increase in competition. After calibrating the model to the euro area vs. the...

We develop and estimate a stylized micro-founded model of the US economy. Next we compute the parameters of a simple interest rate policy rule that maximizes the unconditional mean of utility. We show that such a welfare-based rule lies close to the Taylor efficiency frontier. A counterfactual...

We estimate the macroeconomic benefits and international spillovers of an increase in competition using a general-equilibrium simulation model with nominal rigidities and monopolistic competition in product and labor markets. We draw three conclusions after calibrating the model to the euro area...

The Flexible System of Global Models (FSGM) is a group of models developed by the Economic Modeling Division of the IMF for policy analysis. A typical module of FSGM is a multi-region, forward-looking semi-structural global model consisting of 24 regions. Using the three core modules focused on...

This is the third chapter of a forthcoming monograph entitled "On Implementing Full-Fledged Inflation-Targeting Regimes: Saying What You Do and Doing What You Say." It examines a number of elements in the design of an inflation-targeting framework. These include the definition of the target...

This is the second chapter of a forthcoming monograph entitled "On Implementing Full-Fledged Inflation-Targeting Regimes: Saying What You Do and Doing What You Say." We begin by discussing the costs of inflation, including their role in generating boom-bust cycles. Following a general discussion...

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 develop and estimate a stylized micro-founded model of the US economy. Next we compute the parameters of a simple interest rate policy rule that maximizes the unconditional mean of utility. We show that such a welfare-based rule lies close to the Taylor efficiency frontier. A counterfactual...

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...
