Multimod Mark III: The Core Dynamic and Steady State Model

This study describes the Mark III version of MULTIMOD, the IMFs multi region macroeconomic model. Mark III version of MULTIMOD differs from its predecessor in several important respects. New features include a core steady-state analogue model, a new model of teh inflation-unemployment nexus, and extended non-Ricardian specification of consumption-saving behavior, and improved specifications and estimates of investment behavior and international trade equations. In addition, the introduction of a new solution algorithm has greatly increased the robustness, speed of convergence, and accuracy of the simulations.

GEM; A New International Macroeconomic Model

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 policy analysis. The paper is aimed at a general audience and avoids technical detail. It outlines the motivation, structure, strengths, and limitations of the model; examines three simulation exercises that have been completed; and discusses the future path of GEM.

Frontiers of Monetary Policymaking; Adding the Exchange Rate as a Tool to Combat Deflationary Risks in the Czech Republic

The paper first describes how the Czech National Bank (CNB) moved gradually from a fixed exchange rate regime to the frontiers of Inflation-Forecast Targeting. It then focuses on the CNB’s recent experience in adding the exchange rate as a complementary monetary policy tool to stimulate the economy and combat the risks of deflation when the policy interest rate is at the zero lower bound. It assesses the theoretical basis of such a policy, the communications approach used by the CNB when announcing the new framework, and the effects thus far on inflation and output.

The Macroeconomic Effects of Higher Oil Prices

The paper uses MULTIMOD to analyze the macroeconomic effects of oil price shocks, distinguishing between temporary, more persistent, and permanent shocks. It provides perspectives on several findings in the literature and the key role of monetary policy in influencing macroeconomic outcomes. Specific attention is paid to the channels through which oil price increases can pass through into core inflation, a possible explanation of the asymmetric relationship between oil prices and economic activity, the role of monetary policy credibility, the implications of delayed policy responses, and the relative merits of leaning in different directions when the correct policy response is uncertain.

Macroeconomic Management When Policy Space is Constrained; A Comprehensive, Consistent and Coordinated Approach to Economic Policy

The recovery in GDP growth since the global financial crisis has been halting and weak. Concern is widespread that countercyclical policies have run out of space or lack the power to raise growth or deal with the next negative shock. This note argues that room exists for effective policies and that it should be used if appropriate. The most promising route involves a comprehensive, consistent, and coordinated approach to policy making. Comprehensive policy actions within a country exploit synergies, making the whole greater than the sum of parts. Consistent policy frameworks anchor long-term expectations while allowing decisive short- to medium-term accommodation whenever necessary. Coordinated policies across major economies amplify the helpful effects of individual policy actions through positive cross-border spillovers. The findings of this paper indicate that policy coordination adds particular value if the current approach falls short of reviving growth, or in the event of a further downward shock.

Multivariate Filter Estimation of Potential Output for the United States

Estimates of potential output are an important component of a structured forecasting and policy analysis system. Using information on capacity utilization, this paper extends the multivariate filter developed by Laxton and Tetlow (1992) and modified by Benes and others (2010), Blagrave and others (2015), and Alichi and others (2015). We show that, although still fairly uncertain, the real-time estimates from this approach are more accurate than estimates constructed from naive univariate statistical filters. The paper presents illustrative estimates for the United States and discusses how the end-of-sample estimates can be improved with additional information.

An Index for Transparency for Inflation-Targeting Central Banks: Application to the Czech National Bank

This paper develops a new central bank transparency index for inflation-targeting central banks (CBT-IT index). It applies the CBT-IT index to the Czech National Bank (CNB), one of the most transparent inflation-targeting central banks. The CNB has invested heavily in developing a Forecasting and Policy Analysis System (FPAS) to implement a full-fledged inflation-forecast-targeting (IFT) regime. The components of CBT-IT index include measures of transparency about monetary policy objectives, the FPAS designed to support IFT, and the monetary policymaking process. For the CNB, all three components have shown substantial improvements over time but a few gaps remain. The CNB is currently working on eliminating some of these gaps.

Estimates of Potential Output and the Neutral Rate for the U.S. Economy

Estimates of potential output and the neutral short-term interest rate play important roles in policy making. However, such estimates are associated with significant uncertainty and subject to significant revisions. This paper extends the structural multivariate filter methodology by adding a monetary policy block, which allows estimating the neutral rate of interest for the U.S. economy. The addition of the monetary policy block further improves the reliability of the structural multivariate filter.

Morocco: A Practical Approach to Monetary Policy Analysis in a Country with Capital Controls

The Central Bank of Morocco has been working on developing a Forecasting and Policy Analysis System (FPAS) to support a gradual move toward a more flexible exchange rate regime and the eventual adoption of a full-fledged inflation-targeting (IT) regime. At the center of the FPAS is a quarterly projection model that was tailored for two different types of exchange rate regimes. Presently, the fixed exchange rate model version is to be used during the pre-IT period, while the flexible exchange rate model version is to be used to prepare alternative scenarios for monetary policy decision makers to discuss the potential policy implications of shocks under an IT regime.

Some Simulation Properties of the Major Euro Area Economies in Multimod

This paper was prepared as part of a euro area macroeconomic model comparisons project. Four standard macroeconomic experiments are considered to illustrate the differences in dynamic adjustment properties of two versions of MULTIMOD, the IMFs multicountry macroeconomic model. One version of MULTIMOD that is examined contains separate country blocks for the three major economies in the euro area, Germany, France, and Italy. The second, more recent version, contains a single block describing the behavior of the whole euro area.
