摘要：How can two physically identical gasoline stations differentiate themselves? In this article we develop and test a model of service time competition: some stations set higher prices and thereby offer shorter queues, whereas other offer lower price and longer queues. We find that retail demand is sensitive to service time: customers are, on average, willing to pay about 1% more for a 6% reduction in congestion. Consistent with the service time hypothesis, prices are more dispersed at stations f...

摘要：This article addresses the effect of hospital ownership on the delivery of service to uninsured patients. It compares the volume of uninsured patients treated in for-profit and nonprofit hospitals by regarding hospital ownership and service as endogenous. Instrumental variable estimates are used to predict the percentage of patients who are uninsured, controlling for hospital ownership and service. The study shows that when for-profit and nonprofit hospitals are located in the same area, they ...

摘要：In this article we develop and illustrate a simple algorithm for computing Markov-perfect Nash equilibria. The advantage of the Markov-perfect framework is that it is flexible enough to reproduce important aspects of reality in a variety of market settings. As a result, we hope that our article and (perhaps improved) versions of the associated algorithms will eventually be a part of a tool kit that allows researchers to go back and forth between the implications of economic theory and the char...

摘要：This article considers the problem of ''supply-and-demand'' analysis on a cross section of oligopoly markets with differentiated products. The primary methodology is to assume that demand can be described by a discrete-choice model and that prices are endogenously determined by price-setting firms. In contrast to some previous empirical work, the techniques explicitly allow for the possibility that prices are correlated with unobserved demand factors in the cross section of markets. The articl...

摘要：This article explores how the introduction of new products by multiproduct firms might be affected by existing goods in each firm's portfolio. A logit analysis is conducted to estimate the effects of local monopoly power, cost advantages, and learning. Characteristics theory is used to determine whether the addition of a new product to a firm's existing portfolio creates the potential for local monopoly power. While the chemical similarity of products has the largest effect, results nonetheles...
