"Основни концепции в теорията на поведенческите финанси" (Basic Concepts of Behavioral Finance Theory)

Abstract

This article analyzes the basic concepts of behavior finance and its implied model of the economic agent which differs from the ‘homo economicus’ of traditional finance theory. Systematized are the more realistic assumptions regarding human decision making which stem from research in cognitive psychology and increasingly experimental economics. Outlined are implications for a methodologically more advanced public finance. Possibilities for enhanced economic policy recommendations are derived.
