We study the trade-offs faced by Internet Service Providers (ISPs) that serve as platforms through which consumers access both television and internet services. As online streaming video improves, these providers may respond by attempting to steer consumers away from streaming video toward their...

We estimate demand for residential broadband using high-frequency data from subscribers facing a three-part tariff. The three-part tariff makes data usage during the billing cycle a dynamic problem; thus, generating variation in the (shadow) price of usage. We provide evidence that subscribers...

We investigate the impact of charity tie-ins on transaction probabilities and sale prices using a large database of eBay auctions. We examine "natural experiments" of precisely matched clusters of charity and non-charity auctions with identical titles, subtitles, sellers, and start prices. We...

Quality certification programs help consumers to identify high-quality products or sellers in markets with information asymmetries. Using data from eBay UK's online marketplace, we study how certification's impact on consumer demand varies with market- and seller-level attributes, exploiting...

We study the use of and response to cheap talk by firms and their consumers, focusing on unverifiable promises of charitable donations on eBay. For transactions during March 2005 – May 2006, cheap talk listings have lower sales probabilities but sell at higher prices when they are successful....

We use U.S. eBay data to investigate how trade is influenced by differences in socioeconomic characteristics, tastes, and trust. States' similarity in cultural characteristics (ethnicity, religious affiliations, and political behavior) is predictive of online trade; cultural similarity similarly...

This paper explores the relationship between shelf prices and manufacturers' coupons for 25 ready-to-eat breakfast cereals. Contrary to the predictions of static monopoly price discrimination, we find the shelf prices for a particular brand in a particular city are generally lower during periods...

We compare outcomes obtained by sellers who listed their home on a newly developed For-Sale-By-Owner (FSBO) web site versus those who used an agent and the Multiple Listing Service (MLS). We do not find support for the hypothesis that listing on the MLS helps sellers obtain a significantly...

In this paper I analyze GMM estimation when the sample is not a random draw from the population of interest. I exploit auxiliary information, in the form of moments from the population of interest, in order to compute weights that are proportional to the inverse probability of selection. The...

A common approach to measuring price changes is to look at the change of the expenditure needed to purchase a fixed basket of goods. It is well-known that this approach suffers from problems and creates several biases in the measurement of price changes faced by consumers. Substitution and...
