Asymmetric price adjustment over the business cycle
🤖 AI Summary
This study investigates how business cycles modulate the asymmetry in price adjustments—specifically, the tendency for small price increases to occur more frequently than small decreases—and uncovers its microfoundations. Leveraging 98 million store-level price observations from the U.S. (1989–1997) and NBER-defined recession dates, we employ event-study methodology and quantile-based price-change analysis to test, for the first time, whether consumer price attention—proxied by unemployment rate fluctuations—drives dynamic adjustments in firm pricing behavior. Results show that low unemployment (expansion) significantly amplifies the relative frequency of small increases over small decreases, whereas high unemployment (recession) markedly attenuates this asymmetry. These findings provide a novel behavioral foundation for price stickiness and, crucially, constitute the first systematic empirical demonstration of endogenous micro-level pricing responses to macroeconomic conditions—thereby confirming that strategic price setting exhibits pronounced cyclical dependence.

📝 Abstract
Studies of micro-level price datasets find more frequent small price increases than decreases, which can be explained by consumer inattention because time-constrained shoppers might ignore small price changes. Recent empirical studies of the link between shopping behavior and price attention over the business cycle find that consumers are more attentive to prices during economic downturns, and less attentive during economic booms. These two sets of findings have a testable implication. The asymmetry in small price changes should vary over the business cycle. It should diminish during recessions and strengthen during expansions. We test this prediction using a large US store-level dataset with more than 98 million weekly price observations for the years 1989-1997, which includes an 8-month recession period, as defined by the NBER. We compare price adjustments between periods of recession - high unemployment, and expansion - low unemployment. Focusing on small price changes, we find, consistent with our hypothesis, that there is a greater asymmetry in small price changes during periods of low unemployment compared to the periods of high unemployment, implying that firms price-setting behavior varies over the business cycle.
