Reading the Tea Leaves of the U.S. Business Cycle—Part One
The study of the business cycle—fluctuations in aggregate economic activity between times of widespread expansion and contraction—is one of the foremost pursuits in macroeconomics. But even distinguishing periods of expansion and recession can be challenging. In this post, we discuss different conceptual approaches to dating the business cycle, study their past performance for the U.S. economy, and highlight the informativeness of labor market indicators.

Okun’s Law and Long Expansions
Economic forecasters frequently use a simple rule of thumb called Okun's law to link their real GDP growth forecasts to their unemployment rate forecasts. While they recognize that temporary deviations from Okun's law may occur, forecasters often assume that sustained reductions in the unemployment rate require robust GDP growth. However, our analysis suggests that Okun's law has not been a consistently reliable tool for predicting the size of declines in the unemployment rate during the last three expansions—a finding that reflects the impact of changes in the labor market since the early ...

Reading the Tea Leaves of the U.S. Business Cycle—Part Two
In our previous post, we presented evidence suggesting that labor market indicators provide the most reliable information for dating the U.S. business cycle. In this post, we further develop the case. In fact, the unemployment rate has provided an almost perfect record of distinguishing the beginning of recessions in the post-war U.S. economy. We also show that using more granular labor market data, such as by region or industry, also provides valuable information about the state of the business cycle.
