We test convergent validity of contingent valuation and choice modeling with field and eye-tracker data in an application for stone pine reforestations. Field results yield significantly different structural models and higher willingness to pay values in choice modeling. Eye-tracker results show that respondents devote relatively more time to attributes and the bid in choice modeling and that there are no significant differences in the total time used to answer. Divergences remain for modified formats that minimize visual and cognitive differences between methods. Using an attribute-stimulus format in contingent valuation or including dominant alternatives in choice modeling does not change results. © 2015 Department of Forest Economics, SLU Umeå, Sweden.

We perform two convergent validity tests in a choice experiment applied to public recreation in Spanish stone pine and cork oak forests. Results show convergent validity between a choice and a ranking recoded as a choice format in an experiment with three alternatives plus status quo. We also find significant differences between two payment vehicles (increased trip expenditures and entrance fee) that are included simultaneously in the choice sets. We estimate aggregated recreation values using compensating variation and simulated exchange value (maximum benefits from a potential market) measures. The latter measures account for 35–51% of the former values. © 2016 Department of Forest Economics, Swedish University of Agricultural Sciences, Umeå
