In this paper, we analyze the service provided by the 13 largest U.S. passenger airlines to the 100 most populous U.S. metropolitan areas in 1989. We classify the route systems by their nature and geographic scope using a variety of measures based on route-level data. We then identify individual...

In this paper, we analyze the service provided by the 13 largest U.S. passenger airlines to the 100 most populous U.S. metropolitan areas in 1989. We classify the route systems by their nature and geographical extent using a variety of measures based on route-level data. We then identify...

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.

This paper analyzes the influence of highway safety regulation enforcement efforts on motor vehicle fatalities. It estimates a regression model in which such deaths depend on these efforts as well as economic conditions, driver characteristics, government regulations, and locational factors,...

This paper uses seemingly unrelated regression analysis and annual Ohio data for 1975-2000 to estimate a model for six different types of motor vehicle fatalities: car occupants, light truck occupants, large truck occupants, motorcyclists, pedestrians, and pedalcyclists. It finds that while...

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...

The 1996 welfare reform legislation has spawned a multitude of studies of the experiences of welfare recipients and their families since the reforms have been implemented (e.g. U.S. Department of Health and Human Services, 2000; Cancian, Haveman, Kaplan, Meyer and Wolfe, 1999; Harris, 1996; Coulton et al.,...

GIS methods are used to construct measures of food access for neighbourhoods in the Portland, Oregon, US metropolitan area and the sensitivity of such measures to methodological variation is examined. The level of aggregation of data inputs is varied and the effect of using both Euclidean and...
