The 1997 edition of the NBER Macroeconomic as usual contains, as usual, a mixture of policy-focused research and studies of broader positive issues within macroeconomics.

New goods are at the heart of economic progress. The eleven essays in this volume include historical treatments of new goods and their diffusion; practical exercises in measurement addressed to recent and ongoing innovations; and real-world methods of devising quantitative adjustments for quality change. The lead article in Part I contains a striking analysis of the history of light over two millenia. Other essays in Part I develop new price indexes for automobiles back to 1906; trace the role of the air conditioner in the development of the American south; and treat the germ theory of disease as an economic innovation. In Part II essays measure the economic impact of more recent innovations, including anti-ulcer drugs, new breakfast cereals, and computers. Part III explores methods and defects in the treatment of quality change in the official price data of the United States, Canada, and Japan. This pathbreaking volume will interest anyone who studies economic growth, productivity, and the American standard of living.

The 20th NBER Macroeconomics Annual, covering questions at the cutting edge of macroeconomics that are central to current policy debates.

The NBER Macroeconomics Annual 2021 presents research-central issues in contemporary macroeconomics. Robert Hall and Marianna Kudlyak examine unemployment dynamics during economic recoveries. They present new empirical findings and explore models in which the labor market gradually draws down the stock of unemployed workers in the aftermath of a downturn. Titan Alon, Sena Coskun, Matthias Doepke, David Koll, and Michèle Tertilt analyze the relative decline in employment of women during the COVID-19 pandemic and the associated global recession. They show that increased childcare needs, which fell more heavily on women, and differences in occupations both contributed. In the case of the US, however, each of these factors account for less than 20% of the gender gap in hours worked during the pandemic. Richard Rogerson and Johanna Wallenius study the employment rates of older workers in OECD countries over the last forty years. An expansion of institutions incentivizing retirement, concurrent with negative aggregate shocks between 1970 and 1995, led to falling employment rates. This trend started to reverse in the mid-1990s when many of these institutions, such as public pension programs, were cut back. Michael Barnett, William Brock, and Lars Peter Hansen explore the consequences of risk, ambiguity, and model misspecification in climate policy design. They consider carbon emissions pricing and the effects of different sources of uncertainty—such as future information about environmental damage, uncertainties in carbon and temperature dynamics and damage functions, and the role of future green technologies—on policy design. Michael Kremer, Jack Willis, and Yang You present new evidence suggesting a steady trend toward income convergence across countries since the late 1980s. They find convergence in various determinants of economic growth across countries and a flattening of the relationship between growth and these determinants. The paper challenges theories of growth arising after earlier rejections of the neoclassical growth model.

While there is ample evidence that high inflation is harmful, little is known about how best to reduce inflation or how far it should be reduced. In this volume, sixteen distinguished economists analyze the appropriateness of low inflation as a goal for monetary policy and discuss possible strategies for reducing inflation. Section I discusses the consequences of inflation. These papers analyze inflation's impact on the tax system, labor market flexibility, equilibrium unemployment, and the public's sense of well-being. Section II considers the obstacles facing central bankers in achieving low inflation. These papers study the precision of estimates of equilibrium unemployment, the sources of the high inflation of the 1970s, and the use of non-traditional indicators in policy formation. The papers in section III consider how institutions can be designed to promote successful monetary policy, and the importance of institutions to the performance of policy in the United States, Germany, and other countries. This timely volume should be read by anyone who studies or conducts monetary policy.
