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.

The Global Integrated Monetary and Fiscal model (GIMF) is a multi-region DSGE model developed by the Economic Modeling Division of the IMF for policy and scenario analysis. This paper compares two versions of GIMF, GIMF with a conventional financial accelerator, where bank balance sheets do not play a prominent role, and GIMF with both a financial accelerator and a fully specified banking sector that can make lending losses, and that is regulated according to Basel-III. We illustrate the comparative macroeconomic properties of both models by presenting their responses to a wide range of fiscal, demand, supply and financial shocks.

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 the G-20, the euro area, and emerging market economies, this paper outlines the theory under-pinning the model, and illustrates its macroeconomic properties by presenting its responses under a wide range of experiments, including monetary, financial, demand, supply, fiscal and international shocks.

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 macroeconomic properties by presenting its responses under a wide range of experiments, including fiscal, monetary, financial, demand, supply, and international shocks.

We develop a DSGE model with a banking sector to analyze the impact of the financial crisis on Zambia and the role of the monetary policy response. We view the crisis as a combination of three related shocks: a worsening in the terms of the trade, an increase in the country’s risk premium, and a decrease in the risk appetite of local banks. We characterize monetary policy as "stop and go": initially tight, subsequently loose. Simulations of the model broadly match the path of the economy during this period. We find that the initial policy response contributed to the domestic impact of the crisis by further tightening financial conditions. We study the factors driving the "stop" part of policy and derive policy implications for central banks in low-income countries.

"Fiscal policy makers have faced an extraordinarily challenging environment over the last few years. At the outset of the global financial crisis, the International Monetary Fund (IMF) for the first time advocated a fiscal expansion across all countries able to afford it, a seeming departure from the long-held consensus among economists that monetary policy rather than fiscal policy was the appropriate response to fluctuations in economic activity. Since then, the IMF has emphasized that the speed of fiscal adjustment should be determined by the specific circumstances in each country. Its recommendation that deficit reduction proceed steadily, but gradually, positions the IMF between the fiscal doves (who argue for postponing fiscal adjustment altogether) and the fiscal hawks (who argue for a front-loaded adjustment). This volume brings together the analysis underpinning the IMF's position on the evolving role of fiscal policy. After establishing its analytical foundation, with chapters on such topics as fiscal risk and debt dynamics, the book analyzes the buildup of fiscal vulnerabilities before the crisis, presents the policy response during the crisis, discusses the fiscal outlook and policy challenges ahead, and offers lessons learned from the crisis and its aftermath. Topics discussed include a historical view of debt accumulation; the timing, size, and composition of fiscal stimulus packages in advanced and emerging economies; the heated debate surrounding the size of fiscal multipliers and the effectiveness of fiscal policy as a countercyclical tool; coordination of fiscal and monetary policies; the sovereign debt crisis in Europe; and institutional reform aimed at fostering fiscal discipline."--Publisher's description.
