The basic tools for analyzing macroeconomic fluctuations and policies, applied to concrete issues and presented within an integrated New Keynesian framework. This textbook presents the basic tools for analyzing macroeconomic fluctuations and policies and applies them to contemporary issues. It employs a unified New Keynesian framework for understanding business cycles, major crises, and macroeconomic policies, introducing students to the approach most often used in academic macroeconomic analysis and by central banks and international institutions. The book addresses such topics as how recessions and crises spread; what instruments central banks and governments have to stimulate activity when private demand is weak; and what “unconventional” macroeconomic policies might work when conventional monetary policy loses its effectiveness (as has happened in many countries in the aftermath of the Great Recession.). The text introduces the foundations of modern business cycle theory through the notions of aggregate demand and aggregate supply, and then applies the theory to the study of regular business-cycle fluctuations in output, inflation, and employment. It considers conventional monetary and fiscal policies aimed at stabilizing the business cycle, and examines unconventional macroeconomic policies, including forward guidance and quantitative easing, in situations of “liquidity trap”—deep crises in which conventional policies are either ineffective or have very different effects than in normal time. This book is the first to use the New Keynesian framework at the advanced undergraduate level, connecting undergraduate learning not only with the more advanced tools taught at the graduate level but also with the large body of policy-oriented research in academic journals. End-of-chapter problems help students master the materials presented.

Macroeconomic policy is one of the most important policy domains, and the tools of macroeconomics are among the most valuable for policy makers. Yet there has been, up to now, a wide gulf between the level at which macroeconomics is taught at the undergraduate level and the level at which it is practiced. At the same time, doctoral-level textbooks are usually not targeted at a policy audience, making advanced macroeconomics less accessible to current and aspiring practitioners. This book, born out of the Masters course the authors taught for many years at the Harvard Kennedy School, fills this gap. It introduces the tools of dynamic optimization in the context of economic growth, and then applies them to a wide range of policy questions – ranging from pensions, consumption, investment and finance, to the most recent developments in fiscal and monetary policy. It does so with the requisite rigor, but also with a light touch, and an unyielding focus on their application to policy-making, as befits the authors’ own practical experience. Advanced Macroeconomics: An Easy Guide is bound to become a great resource for graduate and advanced undergraduate students, and practitioners alike.

Over five editions, Macroeconomics has remained among the most popular intermediate texts in the field.

This paper studies the sources of macroeconomic fluctuations in developing countries using a structural VAR approach. Identification of the sources is achieved using long-run restrictions derived from a theoretical model of a small open economy encompassing a large number of macroeconomic paradigms; the short-run dynamics are unrestricted. This framework is applied to Brazil and Korea. The results confirm that supply shocks are the main source of GDP fluctuations, even in the short run. Aggregate demand shocks are shown to be important in the short run in Brazil, but not in Korea. External shocks explain a small fraction of the variance of output, whereas the real exchange rate is driven mainly by fiscal shocks. Nominal shocks appear to have little impact on output and the real exchange rate.

Since the five largest industrial democracies concluded the Plaza Agreement in 1985, the theory and practice of international economic policy coordination has become the subject of spirited academic and public-policy debate. While some view policy coordination as crucial for the construction of an improved international monetary system, others fear that it risks delaying or weakening the implementation of macroeconomic and structural policies. In these papers and comments, prominent international economists consider past and present interpretations of the meaning of international policy coordination; conditions necessary for coordination to be beneficial both to the direct participants and the global economy; influential factors for the quantitative impact of coordination; obstacles to coordination; the most—and least—effective methods of coordination; and future directions of the coordination process, including processes associated with greater fixity of exchange rates. These studies will be readily accessible to policymakers, while offering sophisticated analyses to interested scholars of the global economy.
