The Festschrift in honor of Christian Seidl gathers a group of prominent authors being experts in areas like Public Economics, Welfare Economics, Social Choice Theory, Public Choice Theory, Decision Theory and Experimental Economics. Christian Seidl, known as one of the editors of the three-volume Handbook of Utility Theory , has dedicated his research to utility-theoretic fundamentals, and the welfare implications of individual and group decision making. During the last decade, he has turned part of his attention to a research tool that has gained a lot of importance in economics: the laboratory experiment. The Advances in Public Economics: Utility Choice and Welfare is an attempt to illuminate all facets of Christian Seidl’s research agenda by presenting an ambitious collection of both purely theoretical and experimental papers on utility, choice and welfare, written by his closest friends and colleagues.
