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...

In this paper we carry out technical efficiency and productivity growth comparisons among the four largest European carriers and eight of their American counterparts. The time period of our comparisons is 1976 through 1986. This is a particularly interesting period since it begins just after the...

Previous research on male subjects has conjectured that subjective self-reports of health status may lead to an upward bias in the estimated effect of health on labor force participation because subjects who are out of the labor force may be more likely to understate their health status so as to...

Cornwell, Schmidt, and Sickles (1990) and Kumbhakar (1990), among others, developed stochasticfrontier production models which allow firm specific inefficiency levels to change over time. These studies assumed arbitrary restrictions on the short-run dynamics of efficiency levels which have...

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...

It is common in firm level environmental efficiency studies for pollution to form part of the production technology. We omit nitrogen and sulphur emissions from the spatial analysis of production in European countries (1995 - 2008) because we find they are not significant inputs. Efficiency and...
