Empirical evidence suggests that prices are sticky with respect to cost changes. Moreover, prices respond more rapidly to cost increases than to cost decreases. We develop a search theoretic model which is consistent with this evidence and allows for additional testable predictions. Our results...

This paper shows that prices may be sticky when buyers must search to determine the current market price and there is uncertainty about the expected duration of cost changes. Specifically, during periods when costs, and hence prices are high, low valuation consumers optimally stop searching and...
