Resumen de Research note: strategic behaviour in multiple purpose data collection - a travel cost application to Barcelona Zoo

Verónica Farreras, Pere Riera Micaló

• Some tourism and recreational values are estimated by the travel cost method (TCM) using secondary data. The purpose of the primary collection could suffer from incentive compatibility problems. This being the case, the TCM value estimates may be biased, and extra care should be taken. This article provides theoretical background and illustrates the problem with a case study of visitors to Spain's Barcelona Zoo.
