The objective of this study is to estimate the effects of competition for both Medicare and HMO patients on the quality decisions of hospitals in Southern California. We use discharge data from the State of California for the period 1989-1993. The outcome variables are the risk-adjusted hospital...

We estimate a structural model of the market for automatic teller machines (ATMs) evaluate the implications of regulating ATM surcharges on ATM entry and consumer producer surplus. We estimate the model using data on firm and consumer locations, the parameters of the model by exploiting a source...

We seek to estimate the causes and magnitudes of network externalities for the automated clearinghouse (ACH) electronic payments system, using a panel data set on individual bank usage of ACH. We construct an equilibrium model of consumer and bank adoption of ACH in the presence of a network....

We estimate a bargaining model of competition between hospitals and managed care organizations (MCOs) and use the estimates to evaluate the effects of hospital mergers. We find that MCO bargaining restrains hospital prices significantly. The model demonstrates the potential impact of coinsurance...

This paper proposes methods for identifying indirect network eects with dynamically optimizing consumers purchasing a durable hardware good and associated software. We apply this model to data drawn from the DVD player and titles markets. We observe model-level prices, sales and characteristics...

Most new consumer durable goods experience rapid declines in prices and improvements in qual- ity, suggesting the importance of modeling dynamics. This paper estimates a dynamic model of consumer preferences for new durable goods with persistent heterogeneous consumer tastes, rational...

Most new consumer durable goods experience rapid prices declines and quality improvements, suggesting the importance of modeling dynamics. This paper specifies a dynamic model of consumer preferences for new durable goods with persistently heterogeneous consumer tastes, rational expectations,...

This paper seeks to understand the impact of the Medicare Rural Hospital Flexibility (Flex) Program on rural resident hospital choice and welfare. The Flex program created a new class of hospital, the Critical Access Hospital (CAH), which receives more generous reimbursement in return for limits...

This paper comments on "The Price Effects of Hospital Mergers: A Case Study of Sutter-Summit Transaction" by Steven Tenn. I exposit a simple model of differentiated products competition and consider the implications of Tenn's findings in the context of this model. I find that Tenn provides...
