This paper outlines the evolution and classification of the major works (published books) of Clem Tisdell. To do this it divides these books into six categories. 1. Those focusing on knowledge limitations and, the presence of uncertainty (information economics). These develop microeconomic theory and apply it to policy issues. Subjects covered include the operation of market systems, the economics of decision-making, managerial economics, science and technology policy, bounded rationality, and evolutionary economics. 2. Textbooks on microeconomics and basic economics. 3. Ecological, natural resource and environmental economics. 4. Tourism economics and leisure studies. 5. Economic development in general and in particular, Asian-Pacific countries or regions. 6. Social policy, which includes coverage of gender issues, social issues associated with globalization, and the investigation of poverty and social disadvantage. The subject matter of several of these books overlaps and other classifications are also possible. Some of Tisdell’s books are co-authored and several are jointly edited. In addition, a collection of his articles (several of which are jointly authored) have not yet appeared in book form. Note that this overview is not intended to provide an in-depth analysis of recurring themes in Tisdell’s books and the development of these.
