The role of right-hand side endogenous variables in travel cost models

In this study, two new travel cost models are presented which show methods for utilizing endogenous right-hand side variables. The first is a theoretical model describing the potential role of site congestion as an equilibrating mechanism in hedonic travel cost models. The second model explicitly considers the recreationist's provisioning of durable recreational equipment in his trips decision via an optimal control methodology. An empirical test of this model, utilizing a simultaneous equations, is then conducted using 1986-7 data on Long Island sport-fishing, and those testable elements of the theoretical models produced the expected results.
