New Keynesian models: not yet useful for policy analysis
Macroeconomists have largely converged on method, model design, reduced-form shocks, and principles of policy advice. Our main disagreements today are about implementing the methodology. Some think New Keynesian models are ready to be used for quarter-to-quarter quantitative policy advice; we do not. Focusing on the state-of-the-art version of these models, we argue that some of its shocks and other features are not structural or consistent with microeconomic evidence. Since an accurate structural model is essential to reliably evaluate the effects of policies, we conclude that New Keynesian ...

Quid pro quo: Technology capital transfers for market access in China
Despite the recent rapid development and greater openness of China?s economy, FDI flows between China and technologically advanced countries are relatively small in both directions. We assess global capital flows in light of China?s quid pro quo policy of exchanging market access for transfers of technology capital?accumulated know-how such as research and development (R&D) that can be used in multiple production locations. We first provide empirical evidence of this policy and then incorporate it into a multicountry dynamic general equilibrium model. This extension leads to a significantly ...

Changes in the distribution of family hours worked since 1950
This paper describes trends in average weekly hours of market work per person and per family in the United States between 1950 and 2005. We disaggregate married couple households by skill level to determine if there is a pattern in the hours of work by wives and husbands conditional on either husband's wages or on husband's educational attainment. The wage measure of skill allows us to compare our findings to those of Juhn and Murphy (1997), who report on trends in family labor using a different data set. The educational measure of skill allows us to construct a longer time series. We find ...

The labor productivity puzzle
Prior to the mid-1980s, labor productivity growth was a useful barometer of the U.S. economy?s performance: it was low during economic recessions and high during expansions. Since then, labor productivity has become significantly less procyclical. In the recent recession of 2008?2009, labor productivity actually rose as GDP plummeted. These facts have motivated the development of new business cycle theories because the conventional view is that they are inconsistent with existing business cycle theory. In this paper, we analyze recent events with existing theory and find that the labor ...

A progress report on business cycle models
This article reports the recent progress made by researchers trying to build business cycle models that can reliably reproduce aggregate U.S. time series. The article first describes some features of the U.S. data that the models are meant to reproduce. Then it describes a version of the standard business cycle model, along with the indivisible labor extension of that model, both of which assume that fluctuations in economic activity are caused only by shocks to technology. Finally, it describes a version of recent other extensions which assume that shocks to fiscal variables also contribute ...

Comparing alternative representations and alternative methodologies in business cycle accounting
We make two comparisons relevant for the business cycle accounting approach. We show that in theory representing the investment wedge as a tax on investment is equivalent to representing this wedge as a tax on capital income as long as the probability distributions over this wedge in the two representations are the same. In practice, convenience dictates differing probability distributions over this wedge in the two representations. Even so, the quantitative results under the two representations are essentially identical. We also compare our methodology, the CKM methodology, to an alternative ...

Changes in hours worked, 1950?2000
This article describes changes in the number of average weekly hours of market work per person in the United States since World War II. Overall, this number has been roughly constant; for various groups, however, it has shifted dramatically - from males to females, from older people to younger people, and from single- to married-person households. The article provides a detailed look at how the lifetime pattern of work hours has changed since 1950 for different demographic groups. This article also documents several factors that lead to the reallocation of hours worked across groups: ...
