We offer and provide empirical support for a new theory of asymmetric pricing in wholesale prices. Wholesale prices may adjust asymmetrically in the small but symmetrically in the large, when retailers face cost of price adjustment. Such retailers will not adjust prices for small changes in their costs. Manufacturers then see a region of inelastic demand where small wholesale price changes do not translate into commensurate retail price changes. The implication is asymmetric—a small wholesale price increase is more pro±table because manufacturers will not lose customers from higher retail prices; yet, a small decrease is less pro±table, because it will not lower retail prices; hence, there is no extra revenue from greater sales. For larger changes, this asymmetry in the behavior of wholesale price vanishes as the price adjustment cost is compensated by the increase in retailers’ revenue resulting from correspondingly large retail price changes. We present a formal economic model of a channel with forward-looking retailers and cost of price adjustment, test the derived propositions on the behavior of manufacturer prices using a large supermarket scanner data set, and ±nd that the results are consistent with the predictions of our theory. We then discuss the implications for asymmetric pricing, channels, and cost of price adjustment literatures, as well as public policy.

Introduction Asymmetric pricing or what is also known as asym- metric price adjustment is a phenomenon where prices rise readily but fall slowly. Frequent reports in the popular press lament the fact that prices are asymmetric. It is not uncommon to read headlines about prices “rising like rockets 000 (but) falling like feathers” ( Octane Week 1999); retail pork prices not coming down even if hog prices do ( New York Times 1999); and government subsidies to dairy farmers not lowering dairy products prices, even if a hike in the
