The conventional wisdom in macroeconomic modeling is to attribute business cycle fluctuations to innovations in the level of the fundamentals. Though volatility shocks could be important too, their propagating mechanism is still not well understood partly because modeling the latent volatilities...

This paper investigates the degree of short run and long run comovement in U.S. sectoral output data by estimating sectoral trends and cycles. A theoretical model based on Long and Plosser (1983) is used to derive a reduced form for sectoral output from first principles. Cointegration and common...

This paper develops a set of approximate band-pass filters designed for use in a wide range of economic applications. In particular, we design and implement a specific band-pass filter which isolates business-cycle fluctuations in macroeconomic time series. This filter was designed to isolate...

This paper evaluates the consistency of the NBER business cycle reference dates over time. Analysis of the NBER methods suggests that the early turning points are derived from detrended data, while the dates after 1927 are derived from data in levels. To evaluate the importance of this and other...

Real exchange rates between the yen and dollar based on general price indexes overestimate the competitiveness of the United States relative to Japan. High productivity growth in the traded sector of the Japanese economy results in a continuous fall in the prices of traded goods relative to...

U.S. balance-of-payments problems in the 1960s remain poorly understood. In this paper I argue that they had two aspects. On the one hand there was a problem of real overvaluation, evident in the erosion of the current account and reflecting the reluctance of the Fed, the Executive and Congress...

In 2021, the Biden Administration issued mandates requiring COVID-19 vaccinations for U.S. federal employees and contractors and for some healthcare and private sector workers. Although these mandates have been subject to legal challenges and some have been halted or delayed, rigorous appraisal...

The dismal decade of 2010-19 recorded the slowest productivity growth of any decade in U.S. history, only 1.1 percent per year in the business sector. Yet the pandemic appears to have created a resurgence in productivity growth with a 4.1 percent rate achieved in the four quarters of 2020. This...

Economists have studied the impact of numerous state laws, from welfare rules to voting ID requirements. Yet for all this policy evaluation, what do we know about policy diffusion—how these policies spread from state to state? We present a series of facts based on a data set of over 700 U.S....

I examine changes in the incidence and consequences of job loss between 1981 and 2001 using data from the Displaced Workers Surveys (DWS) from 1984-2002. The overall rate of job loss has a strong counter-cyclical component, but the job loss rate was higher than might have been expected during...
