Purpose – The purpose of this paper is to empirically investigate the linkage between obesity and motor vehicle deaths. Design/methodology/approach – The paper specifies a model that explains highway fatalities, which accounts for obesity in its set of potential determinants. State‐level...

Although the airline industry has been studied extensively since passage of the Airline Deregulation Act of 1978, relatively little effort has gone into examining how hub location affects the level of service and degree of competition found at airports in the system. To help close this gap, we...

Using a model developed to examine the determinants of air fares, the authors discuss the relationship between airline industry competitiveness and fare increases.
