This paper examines the factors which affect game‐day attendance at National Football League games during the 1991 season. Using a Tobit analysis, the model includes economic as well as quality of game variables as explanatory variables. This analysis reveals that: higher ticket prices reduce attendance with the demand appearing to be inelastic; and a winning home team spurs game‐day attendance.

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 individual airline hub locations and derive and calculate several measures of the extent of competition both on individual routes and at the airports in our sample. The results show the wide diversity of route networks that existed in the airline industry in 1989-a phenomenon that may help to explain the failure of several major carriers since then.

Objective. This article assesses the effectiveness of mandated seat belt usage. The theory of offsetting behavior asserts that when drivers feel safer, they compensate by driving less cautiously. As a consequence, any lifesaving effects from mandated safety devices such as seat belts could be significantly diminished or entirely offset. Method. This article uses regression analysis and two years (1988 and 1997) of state-level data to test for the presence of offsetting behavior by estimating models explaining total and nonoccupant motor vehicle deaths. In addition to accounting for several factors generally acknowledged as being determinants of highway deaths, the models control for the impact of primary and secondary seat belt laws. Results. The findings suggest the existence of offsetting behavior by drivers of motor vehicles. Conclusions. We need to recognize the probability of such compensatory behavior and direct our efforts at ways of ameliorating the adverse effects.
