We propose a polynomial logit model to quantify the price effects of mergers in a static Nash setting. The proposed model is parsimonious in parameters and is shown to have excellent predictive power, rivaling the in-sample and out-of-sample predictive accuracy of the widely-used AIDS model.The...

Damage estimation in mass torts involving hazardous or defective products is often complicated by the unknown time-profile of disease incidence or failure rate. Because these cases involve diseases with long latencies or involve products that fail after years of productive use, estimation of the...

We develop a simultaneous equations estimation framework to understand the interactions among generic entry, prices, and market shares. We base our estimates on a panel data sample of 40 brand-name drugs that first experienced generic competition during the period July 1992-January 1998. We find...

We examine the economic implications of pure bundling under the settings of monopoly and duopoly. We show that under monopoly and pure bundling of goods with independent demands, the bundled price is strictly less than the sum of the unbundled prices. In the setting of duopoly and Nash prices,...

We examine prices, profits, and consumer surplus for differentiated complementary goods under duopoly and a multi-product monopoly. We find that little can be said about the relative magnitudes of prices of the components of a system of complementary goods under the alternative market...
