We construct a panel of eBay seller histories and examine the importance of eBay's reputation mechanism. We find that, when a seller first receives negative feedback, his weekly sales rate drops from a positive 5% to a negative 8%; subsequent negative feedback ratings arrive 25% more rapidly...

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...

We provide a simple framework to analyze the effect of firm dominance on incentives for R&D. An increase in firm dominance, which we measure by a premium in consumer valuation, increases the dominant firm's incentives and decreases the rival firm's incentives for R&D. These changes influence the...
