Seasonal adjustment is a key statistical procedure underlying the creation of many economic series. Large economic shocks, such as the 2007-09 downturn, can generate lasting seasonal echoes in subsequent data. In this Liberty Street Economics post, we discuss the prospects for these echo effects after last year’s sharp economic contraction by focusing on the payroll employment series published by the U.S. Bureau of Labor Statistics (BLS). We note that seasonal echoes may lead the official numbers to overstate actual changes in payroll employment modestly between March and July of this year after which distortions flip the other way.
New work by Richard Crump, Domenico Giannone, and David Lucca finds labor market data to be the most reliable information for dating the U.S. business cycle.
Inventory investment plays a central role in business cycle fluctuations. This post examines whether inventory investment amplifies or dampens economic fluctuations following a tightening in financial conditions. We find evidence supporting an amplification mechanism. This analysis suggests that inventory accumulation will be a drag on economic activity this year but provide a boost in 2020.
