Teoria do prospecto: uma análise do comportamento sob risco do profissional do setor privado

Abstract

This study presents an introduction to the fundamental concepts of Behavioral Finance, focusing on one of its most important cognitive biases - loss aversion, confronting the traditionally accepted paradigm of Modern Finance Theory and its rationality assumptions of economic agents, taking as a reference point the main research carried out in this regard, The Prospect Theory, adapted the pioneering study carried out by professors David Kahneman and Amós Tversky, who won the Nobel Prize in 2002. Their prospectus questionnaire was applied to a sample of professionals in the private sector, with the objective of assessing whether the professional sector or professional experience would influence decisions at risk and verify the consistency of responses with the biases and heuristics identified in the original research. The results proved that the agents are not rational, and that the professional sector and professional experience did not influence the agents' decision making, presenting a behavior consistent with that identified in the pioneering research.
