ABSTRACT
There is a sea change under way, driven by forces unlikely to diminish in magnitude or direction for a good many years. The phenomenon I refer to is the need for and inclusion of other social scientists in research programs in several critical areas of environmental economics. Such research programs involve estimating nonmarket and nonuse values and conducting risk assessment or risk-benefit analysis. Other social scientists include cognitive psychologists who know how people perceive and make decisions and survey or market researchers who have special knowledge about survey design instruments.
