Abstract: We empirically examine the trade-off between the benefits of buying online and the benefits of buying in a local retail store. How does a consumer’s physical location shape the relative benefits of buying from the online world? We explore this problem using data from Amazon on the top selling books for 1497 unique locations in the US for 10 months ending in January 2006. In particular, we examine what happens when a large bookstore opens and when a discount retailer opens. We show that even controlling for productspecific preferences by location, changes in local retail options have substantial effects on online purchases. When a store opens locally, we find evidence that people substitute away from online purchasing, demonstrating that consumers appear to respond to increased convenience in the offline channel. These estimates are economically large, suggesting that disutility costs of purchasing online are substantial and that offline transportation costs matter. We also show that offline entry decreases consumers’ sensitivity to online price discounts. We find no consistent evidence that the breadth of the product line at a local retail store affects purchases although breadth seems to matter in university towns and larger cities. Our paper shows that the parameters in existing theoretical models of channel substitution such as offline transportation cost, online disutility cost, market coverage, and the prices of online and offline retailers interact to determine consumer choice of channels. In this way, our results provide empirical support for many such models.
