Two-constraint models are common in recreation-demand analysis because of the important role time can play in consumer choices. Two versions of Roy's identity hold for these models and imply coefficient restrictions on empirical demand functions. The two-constraint restrictions are fully...

This research seeks to produce more robust, less biased estimates from the two-constraint recreation demand model by applying globally flexible estimation techniques to travel cost data for California whale watching trips. While locally flexible functional forms do improve upon previously used...

The varying researcher assumptions about model specification in nested-logit random utility models can have significant effects on model estimates and corresponding welfare measures. Using a three-level nested-logit model of Oregon marine sport fishing, we estimate and compare several models...

When consumer choice is constrained by time as well as money, willingness to pay can be defined with respect to either numeraire. The two measures can be related formally within a utility-consistent model of choice subject to two constraints. Furthermore, when information is collected on both,...

An approach to jointly estimating an endogenous marginal value of time function and a recreation budget share equation is developed. The specification requirements for the marginal value of time function, to ensure consistency with the maintained hypothesis of two binding constraints on choice,...

How researchers treat the opportunity cost of time substantially influences recreation demand parameter and welfare estimates. This paper presents a utility-theoretic and implementable approach, estimating the shadow value of time jointly with recreation demands for coastal activities, using a...

An alternative methodology for determining marginal willingness to pay values for recreational fishing trips is developed based on inverse demand systems and the distance function. Our empirical application uses joint estimation of several species-specific site equations from a recreation...
