This article presents a theoretical and empirical model to examine competition in physician private practices implementing a conjectural variation framework. Our study uses the 1998 American Medical Association Physician Socioeconomic Monitoring Survey and tests for collusion and market power in...

This paper analyzes the association between two firm performance measures: stock market returns and relative technical efficiency. Using linear programming techniques (Data Envelopment Analysis and Free Disposal Hull), technical efficiencies are calculated for a panel of eleven US airlines...

We model the economically optimal dynamicoil production decisions of a representative country whose oilfields resemble the largest developed oil field in Saudi Arabia,Ghawar. A government-controlled enterprise may base its oil productiondecisions on criteria other than maximization of the...

We estimate efficiency and TFP growth for two measures of congestion and two measures of the monetary value of congestion for the largest 88 contiguous cities in the U.S. over the period 1982–2007. Using stochastic frontier analysis we find that the efficiency scores for congestion and the...

In this paper we examine the productive performance of a group of three East European carriers and compare it to thirteen of their West European competitors during the period 1977–1990. We first model the multiple output/multiple input technology with a stochastic distance frontier using...

A positive relationship betweencompetitive pressure and technical efficiency has been demonstratedby several studies; other studies hold forth that airline marketsbehave strategically. We bring these two literatures togetherby presenting a time series methodology to examine strategicpricing...
