The innovation adoption literature has focused primarily on a producer's decision of whether and how much to adopt. An equally pertinent question is when to adopt, because in the case of new technologies it often 'pays to wait' for more information. We propose a double-limit hurdle model to...

Risk preferences and technology are jointly estimated in the nonlinear mean-standard deviation framework for a competitive firm model under price risk. A utility function is proposed that nests various risk preference structures and risk neutrality as empirically refutable special cases. The...

Using the Heckamn approach, either in single-equation or multi-equation settings, general expressions are derived for calculating marginal effects and elasticities. In the conventional calculation of marginal effects, terms related to the change in the inverse of Mills ratio are omitted. Using...

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...

Constructing a data base that is relatively free of bias, this paper provides measures of the returns of hedge fund s as well as the distinctly non-normal characteristics of the data. We provide risk-adjusted measures of performance as well as tests of the degree to which hedge funds live up to...
