Racjonalność w ujęciu ekonomii behawioralnej

This article undertakes the problem of rationality presented in works of behavioral economists. Paper is divided in three sections. In the first, there are described roots of behavioral economics, which can be mainly found in work of Herbert A. Simon, the creator of bounded rationality concept. Second part is focused on the problem of economic experiments, mainly those conducted by Daniel Kahneman and Amos Tversky. In the last part there are described implications of those experiments to the real-world policies (such as economic or social policy). This problem is mostly considered as the idea of libertarian paternalism depicted by Richard Thaler and Cass Sunstein.
