讲座摘要:

Improvements in communication infrastructure and information technology have strived to make both online and offline store visits better experiences and less costly for consumers. In addition, on-site product information search has been unprecedentedly facilitated by provisions of tools such as mobile store apps, search engines, screening/sorting aids, better in-store display, etc. With the decrease in the cost to visit stores, do firms have an incentive to facilitate consumers’ on-site information collection and evaluation on product attributes? This paper attempts to shed light on this important question with a parsimonious economic model that considers both travel cost (transportation cost between firm visits) and search cost (product inspection cost on-site) and explores how they affect consumer search behavior and firms' pricing decisions. Specifically, consumers make a trade-off between how many attributes to evaluate (search depth) and whether to continue the search to the next firm (search breadth). The analysis reveals a novel interaction effect: lower (higher) search cost benefits firms if travel cost becomes lower (higher). Thus, facilitating consumers’ on-site product evaluation may benefit firms in the context of reduced travel cost. These results are built off of interesting roles that travel and search costs play: they play the same role on firms’ competition when search depth is exogenous whereas they play opposite roles—depth and prices increase (decrease) in travel (search) cost—when search depth is endogenous and partial-depth search prevails. Relevant managerial implications are discussed.
