Estimation of Consumers' Willingness-to-Pay for Eco-friendly Mandarine with the Multiple Bounded Discrete Choice Method

Abstract

This study revisits the argument that the multiple bounded discrete choid (MBDC) format embraces the dichotomous choicd (DC), payment card, and open-ended (OE) formats. We want to see whether or not the argument is supported in the field of eco-friendly mandarine over generic one is estimated through the MBCD approach and the results are compared with results from previous studies that utilized other CVM question formats toward the same commodity. The results show that the 95% confidence interval of WTP under 'probably yes' includes those from the OE approach in previous studies, and the confidence interval under 'not sure' comprises that from the double-bounded DB method in an earlier study. This sutdy also compares estimated WTP for eco-friendly mandarine with market prices.
