摘要

This paper undertakes a systematic comparison of the contingent valuation (CV) and choice experiments (CE) methods, and investigates the extent to which either of them are affected by insensitivity to scope. This is achieved by undertaking separate CV estimates of willingness to pay for two nested public goods, both of which are explicitly included in a parallel CE survey. The results indicate that CE values exhibit greater sensitivity to scope than CV values. CE gives significantly larger results than CV for the more inclusive public good and significantly smaller results for the less inclusive public good.
