摘要：Randall (1994) argued that the Travel Cost Method (TCM) cannot generatemonetary measures of recreation site bene￠ts for use in Cost Bene￠t Analysis.Randall argues that what is relevant to recreational decision-making is thesubjective, and unobservable, price of travel, whereas TCM uses the observer-assessed cost of travel. Hence, TCM can at best give ordinally measurable welfareestimates. `Randall's Di¤culty' is formulated as an estimation problem and resultsare derived for that problem. The meaning of, prospects for, and usefulness ofordinal measurement are explored, and the existence of a solution to Randall'sDi¤culty is considered.
