The Routledge Handbook of Philosophy of Economics gives a comprehensive overview of key concepts in the field and provides a forum for its most important debates. These debates include the role of neuroeconomics, the foundations of decision and game theory, mechanisms, significance tests, capabilities, limits of markets, and Nudge policies. In each debate, one scholar presents a new lead article on a topical question in philosophy of economics, and up to three scholars write responses. Short overviews, written by the Handbook's editors, precede each debate, providing context and explaining key concepts. These overviews will best serve advanced undergraduate and beginning graduate students in philosophy, economics and neighboring disciplines, as well as scholars new to the field. The debates themselves will also interest researchers in philosophy and economics and in related fields.
