The implementation of psychological findings into the analysis of economic questions andproblems is the core element of Behavioral Economics. This paper analyses Behavioral Economicsand its relations to psychology and traditional economics to show parallels and differences betweenthe science programs.In the first chapter the theoretical framework is developed, which is necessary for the furtheranalysis, describing some basics of philosophy of science. The second chapter gives an overview ofthe origins of psychology and Behavioral Economics and the development of scientific psychologyregarding their impacts on models of human behavior in traditional economics. An overview ofpresent-day psychology and its latest impact on economics, Neuroeconomics, end chapter two. Inthe third chapter some of the main themes, theories and models of Behavioral Economics arepresented, including rationality, heuristics and biases, framing, preferences, risk and uncertainty,(time-) consistency and other regarding preferences (social preferences). Following this overviewsome fundamental differences of opinion regarding the modelling of human behavior and theformal testing of theories, which are relevant throughout the whole science program, are described.The end of the chapter is formed by an account of the applicability of scientific findings ofBehavioral Economics and an overview of the main criticism, which is almost always involvedwhen research findings are discussed. The experimental approach is almost always part of thecriticism, so the fifth chapter goes into detail about experiments which are also an important sourcefor behavioral models and theories.The conclusions offer a summary of the main dimensions mentioned throughout the paper that canbe used to analyse Behavioral Economics, and distinguish it from other research programs.
