Abstract
We reviewed environmental valuation studies with regard to future developments, particularly in Japan, organizing major previous studies and the latest results of studies of environmental valuation. Firstly, we gave thorough consideration to previous Society for Environmental Economics and Policy Studies reports. Secondly, we introduced a latent class model, a Kuhn-Tucker model, best-worst scaling, and deliberative monetary valuation as new directions in the study of environmental valuation. Thirdly and lastly, we conducted a thorough review of benefit transfer, which is expected to see increasing use in decision making for future policy and business.
