Do Hypothetical and Actual Willingness to Pay Differ in Choice Experiments? - Application to the Valuation of the Environment

• In this paper we test the validity of choice experiments with donations for environmental projects. In particular, we test whether or not willingness to pay for projects differs between a hypothetical and an actual choice experiment. Our results do not indicate that choice experiments suffer from overstatement in hypothetical willingness to pay; and this contrasts the results found in external tests of validity in Contingent Valuation. In addition, internal tests of validity indicate transitive and stable preferences in both experiments
