Sample selection bias in analysis of consumer choice: an application to warmwater fishing demand [Outdoor recreation]

Extract: A theoretical model and empirical application are presented which account for the individual's decision concerning whether or not to recreate as well as the amount of participation once the decision is made. Results for warmwater fishing demand data yielded least squares parameter estimates fairly similar to those provided by an estimator which corrects for sample selection bias. Further research appears warranted regarding the general degree of potential selection bias inherent in outdoor recreation demand data
