Teoria da decisão sob condições de incerteza

Abstract

Nowadays, the world has gone through several social transformations through major technological changes, mainly by information technology. From the moment that a huge flow of data are generated and transmitted via optical and satellite network, reaching millions of people, their ability to process this information may take two biases: they appropriate the information filter and use them in their decisions, or simply discard them. This study aims to present the main theories behind the decision of economic agents in this uncertain world, dynamic and constantly changing. For this, it uses subfields of economics: economics irrational - psychological concepts in economics, economics of uncertainty - theory of expected utility, the information economy - the importance of communication technological advances, and neuroeconomics - the role of emotion in decision-making; to plot ways to better corroborate with the optimal decision under conditions of uncertainty. Finally, we realized that interdisciplinary sciences (economics, psychology and neuroscience), is contributing to a better and more effective analysis of decision making.
