Especially in times of economic change, interdisciplinary approaches provide valuable information toward mastering the socioeconomic challenges ahead. This book contains the proceedings from a joint conference of two major scientific organizations in the intersection of psychology and economics. Both IAREP (International Association for Research in Economic Psychology) and SABE (Society for the Advancement of Behavioral Economics) bring together researchers from different backgrounds who are interested in an interdisciplinary approach to human behavior in economic contexts. The topics of the conference cover a broad range of classical and novel approaches. For example, several contributions include individual and group decision making, social dilemmas, intertemporal choice, and game-theoretical analyses. There are also a variety of topics that concern the management of scarce resources; for example, buying, giving, credit use, investment, tax behavior, and energy-saving. Recurring themes throughout this conference are happiness, well-being, and life satisfaction. Taken together, the conference contributions represent a comprehensive overview of topics in contemporary economic psychology and behavioral economics. The current book aims at conserving this overview and providing a snapshot in the changing history of the field.
