This paper presents the new, interdisciplinary field of science called neuroeconomics. The first part of the paper shows relations between neuroeconomics, classical economics and behavioral economics. Next, the most popular measurement methods used in neuroeconomic experiments are described. Finally, the paper reviews results from neuroconomic research in four areas: 1) choices under risk and uncertainty, 2) moral decision making, 3) intertemporal decision making, 4) economic behavior in the social context.

The article presents an empirical research which aimed at verifying if participation in a cooperation or competition training determined future behaviors during an anonymous, two-person trust game. We applied two variants of training: active and passive. The main hypothesis claimed that participation in a cooperation training activates the social norm of cooperation and induces more cooperative choices in trust games, whereas participation in a competition training reduces the willingness for cooperative choices. We also predicted that an active training would be more effective in activating cooperation and competition norms than a passive one. Finally, it was expected that interrelation of a cooperative decision in a more risky game would reduce the influence of a training-activated norm on the final decision. The results of the experiment confirmed all three hypotheses.
