In an extensive earlier 1998 paper, the author developed a fully utility-theoretic model for the demand for recreational fishing access days, applied to a sample of 3366 Texas Gulf Coast anglers. The model employs "contingent valuation" and "travel cost" data, jointly, in the process of calibrating a single utility function defined over fishing days versus all other foods and services The theoretical specification (quadratic direct utility) and the econometric implementation will not be reproduced here. In this application, the author supplements the original data set with information from the ongoing Resource Monitoring Program of the Texas Department of Parks and Wildlife. The RMP concerns all species, but the report focuses on the abundance of the primary game fish (red drum) across the eight major bay systems and over time. This improves upon earlier studies which utilize endogenous actual catch information. The author allows the parameters of the underlying utility function to vary systematically with exogenously measured abundance to assess the impact of this important resource attribute upon the demand for access days. The author uses empirical estimates ( and counterfactual simulations) of equivalent variation as measures of the social value of the fishery under current conditions and under alternative fish stock scenarios.

Contingent Valuation Assessment of the Economic Damages of Pollution to Marine Recreational Fishing (1989) (pdf)
This paper extends prior research on measuring economic benefits from enhanced recreational fishing, supplementing the original work and data set with information from Texas DPW on fish species, focusing on the abundance of the primary game fish (red drum) across the eight major bay systems and over time. Papers allow the parameters of the underlying utility function to vary systematically with exogenously measured abundance to assess impacts of thisattribute on demand for access days.
