We study consumers' purchase behavior on daily deal websites (e.g., Groupon promotions) using individual clickstream data on the browsing history of new subscribers to Groupon between January and March 2011. We observe two patterns in the data. First, the probability that a given consumer clicks...

We propose a new likelihood-based estimation method for the sequential search model. By allowing search costs to be heterogeneous across consumers and products, we can directly compute the joint probability of the search sequence and the purchase decision when consumers are searching for the...

The authors propose a new approach to simulate the likelihood of the sequential search model. By allowing search costs to be heterogeneous across consumers and products, the authors directly compute the joint probability of the search and purchase decision when consumers are searching for the...

In studying consumer search behavior, researchers typically focus on which products consumers add to their consideration sets (the extensive margin of search). In this article, we attempt to additionally study how much consumers search individual products (the intensive margin of search), by...

Why do consumers revisit previously searched products (“search revisits”) before making a purchase decision? Using a detailed click-stream data set from a popular hotel meta-search engine that uniquely identifies the information (photos, reviews, prices etc.) consumers obtained on every...
