Robert Sugden (born 26 August 1949) is an English author in the area of cognitive and behavioural economics. Professor Sugden’s research combines game theory (mainly experimental game theory and coordination games) with moral and political philosophy. He is associated with the classical-liberal tradition of Hume, Mill, and Hayek. == Theory == In his most cited work, Sugden explored how conventions of property, mutual aid, and voluntary supply of public goods can evolve spontaneously out of the interactions of self-interested individuals and can become moral norms.〔R Sugden, (''The economics of rights, co-operation, and welfare'' ) (1986)〕 Sugden investigated a number of violations of the von Neumann and Morgenstern's expected utility axioms, and developed regret theory as an alternative with Graham Loomes. In support of this work, he developed a number of experimental methods to test theories of decision under risk.〔G Loomes and R Sugden, (Regret theory: An alternative theory of rational choice under uncertainty ) (1982), The Economic Journal〕 His work also deals with economic methods, in which he argues that economic models are not abstractions from, or simplifications of, the real world, but rather descriptions of imaginary worlds whose validity can only be inferred by how reasonable their predictions are.〔R Sugden, (Credible worlds: the status of theoretical models in economics ) (2000), Journal of Economic Methodology 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Robert Sugden (economist)」の詳細全文を読む スポンサード リンク
