- Abstract
While economists have successfully addressed the endogeneity of congestion in revealed preference approaches, little attention has been devoted to measuring congestion. In fact, most applications measure congestion as a simple count of users or, at best, consider the shares of users, defined as the proportion of people visiting a site during the course of the season. However, only when all sites have a similar size or length and the total number of visitors is constant over time, can these measures be used as a proxy for congestion. In general, these assumptions are unrealistic. In this paper we examine site density measures rather than participation shares as a measure of congestion. We show that endogeneity problems can be addressed using a control function approach and demonstrate that the density of users leads to more statistically significant coefficients of congestion.
