Rg. Cummings et Gw. Harrison, WAS THE OHIO COURT WELL INFORMED IN ITS ASSESSMENT OF THE ACCURACY OFTHE CONTINGENT VALUATION METHOD, Natural resources journal, 34(1), 1994, pp. 1-36
The District Court of Appeals for Washington D.C. has upheld a Departm
ent of the Interior ruling that accepts as a best available procedure
for reliably calculating natural resources damages the Contingent Valu
ations Method (CVM). This paper addresses a number of questions that a
re relevant for assessing the reliability, or accuracy, of CVM values.
Empirical evidence concerning the extent to which CVM subjects behave
strategically, i.e., misrepresent their true values, is found to be m
ixed. While results from received empirical studies do not support une
quivocal conclusions one way or another, their results suggest that CV
M values may overestimate real economic commitments by a considerable
margin. It is then argued that the courts cannot accept CVM values out
of hand; they must carefully assess the demonstrated potential for su
ch overestimates of value in their deliberations concerning the use of
results from CVM surveys in CERCLA litigation.
