SUMMARYThis note analyzes the impacts of the fragmentation of economics into different schools of thought and of social science into the sub‐disciplines economics, sociology and psychology. Fragmentation is based on the assumption that it is possible to split the set of an individual's behavioural motives into separable and disjoint subsets. However, this assumption runs counter to the insights in psychology. Moreover, even if splitting up were possible, the different subsets of motives finally need to be checked on consistency and weighted so as to obtain a comprehensive description and explanation. Another serious drawback is that specification of empirical models on the basis of one school of thought or one sub‐discipline leads to omitted variables bias and hence biased estimators and tests. Finally, fragmentation may lead to a 'pick‐and‐mix package', whereby policy‐makers and politicians feel free to use what suits them. The social rationality model together with the methodological approach prevalent in modern sociology is presented as a framework for integrating the schools of thought in economics and the social science sub‐disciplines.

This volume considers, in depth, some valuation methods and aspects of cost benefit analysis, and policy making in environmental economics. Part I contains a number of contingent valuation studies for non-market assets. Part II consists of contributions on the valuation of health and life, and deals with the benefits of reduced morbidity from air pollution control. In Part III, cost benefit analysis for environmental policy-making is discussed in a disequilibrium setting, and in a macroeconomic context. Finally, Part IV deals with aspects of policy-making, particularly benefit estimation for complex policies, and the international aspects of transboundary air pollution in Europe. The book should not only appeal to students and researchers in university departments of economics and ``environmental sciences'' but also to those working in public organisations and associated advisory institutes which are concerned with environmental problems.
