This paper presents empirical evidence supporting the proposition that there is a significant asymmetry in the U.S. output-inflation process, which implies that excess demand conditions are much more inflationary than excess supply conditions are disinflationary. The important policy implication of this asymmetry is that it can be very costly if the economy overheats because this will necessitate a severe tightening in monetary conditions in order to reestablish inflation control. The small model of the U.S. outputinflation process developed in the paper shows that the seeds of large recessions, such as that in 1981-82, are planted by allowing the economy to overheat. This type of asymmetry implies that the measure of excess demand which is appropriate in estimating the Phillips curve cannot have a zero mean; instead, this mean must be negative if inflation is to be stationary. The paper also shows that a failure to account for this important implication of asymmetry can explain why some other researchers may have been misled into falsely accepting the linear model. The empirical results presented in the paper show that the conclusions regarding asymmetry are robust to a number of tests for sensitivity to changes in the method used to estimate potential output and in the specification of the Phillips curve.
This paper examines the evidence on asymmetries in the effects of activity on inflation. Data for the G-7 countries are found to strongly support the view that the inflation-activity relationship is nonlinear, with high levels of activity raising inflation by more than low levels decrease it. In the face of such asymmetries, the average level of output in an economy subject to demand shocks will be below the level of output at which there is no tendency for inflation to rise or fall, contrary to the implications of linear models. One implication of these results is that policymakers can raise the average level of output over time by responding promptly to demand shocks, thus reducing the variance of output around trend.
Central Bank Policy: Theory and Practice analyses various policies, theories and practices adopted by central banks, as well as the institutional arrangements underlying the principles of good governance in policy-making. It is the first book to comprehensively discuss the latest theories and practices of central bank policy.
This paper extends a standard growth model and obtains consistent panel data estimates of the growth retarding effects of military spending via its adverse impact on capital formation and resource allocation. Simulation experiments suggest that a substantial long-term “peace dividend”—in the form of higher capacity output—may result from markedly lower military expenditure levels achieved in most regions during the late 1980s, and the further military spending cuts that would be possible if global peace could be secured.
As a continent, the economy of Europe is currently the largest on Earth. The European Union, or EU, an intergovernmental body composed of most of the European states, is one of the two largest in the world. Of the member states in the EU, Germany has the largest national economy. Thirteen EU countries share a common unit of currency, the Euro. Major economic sectors in Europe include agriculture, manufacturing, and investment. The majority of the EU's trade is with the United States, China, India, Russia and non-member European states. This book focuses on the latest economic and political issues in Europe.
This study describes the Mark III version of MULTIMOD, the IMF's 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.
This study assesses economic developments and policies during the inaugural year of Europe's single currency regime. It analyses the economic performance and prospects of the euro area as a whole, and highlights to what extent aggregate trends are shaped by convergence or divergence.
Previous tests for convexity in the Phillips curve have been biased because researchers have employed filtering techniques for the NAIRU that have been fundamentally inconsistent with the existence of convexity. This paper places linear and nonlinear models of the Phillips curve on an equal statistical footing by estimating model-consistent measures of the NAIRU. After imposing plausible restrictions on the variability in the NAIRU we find that the nonlinear model fits the data best. The implications for the macroeconomic policy debate is that policymakers that are unsuccessful in stabilizing the business cycle will induce a higher natural rate of unemployment.
A selective index of major research papers prepared by IMF staff in 1991-98.
Research activity in the IMF emphasizes the links between the organization's policy and operational concerns. The main objectives of research is IMF staff understanding of policy and operational issues relevant to the institution, and to improve the analytical quality of the work prepared for management and the Executive Board and the advice provided to member countries. The scope of research in the IMF is defined by the purposes and functions of the institution. In order to foster innovation and ensure quality control, the IMF makes much of its research available outside the institution and encourages staff to interact with academia and other research organizations through conferences, seminars, and occasional joint research projects. The visiting scholar’s program has also enhanced the quality of research done in the IMF. This program brings in leading members of the economics profession from around the world to assist in the preparation of papers for the Executive Board and to conduct research on IMF-related issues.
