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...

We explore the relationship between shelf prices and manufacturers' coupons for 25 ready-to-eat breakfast cereals. We find that shelf prices are lower during periods when coupons are available. This result is inconsistent with static monopoly price discrimination under a broad range of...

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...

This paper examines the view that the ready-to-eat cereal industry is a classic example of an industry with nearly collusive pricing behavior and intense non-price competition. In particular, I estimate price-cost margins and separate these margins into three sources: (1) that which is due to...

We model mixed-bundle pricing by internet service providers (ISPs) to study their incentive to steer consumers across different subscription options and influence usage decisions. Using unique panel data from an ISP, we test predictions from the model. We find that the ISP’s introduction of...

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...

Historically, quantitative marketers have largely left public policy and social consideration to economists. This has started to change, and there is considerable potential for marketing to impact policy debates in important ways. We focus on two policy areas – competition policy and nutrition...

Temporary price reductions (sales) are quite common for many goods and usually result in an increase in the quantity sold. We explore whether the data support the hypothesis that these increases are, at least partly, due to dynamic consumer behavior: at low prices consumers stockpile for future...

Economists widely agree that, absent sufficient efficiencies or other offsetting factors, mergers that increase concentration substantially are likely to be anticompetitive. Further, holding everything else equal, the magnitude of anticompetitive effects tends to be larger, the larger is the...
