Rational choice and rational expectations

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


The theory of rational choice assumes that when people make decisions they do so in order to maximize their utility. In order to achieve this goal they ought to use all the information available and consider all the options available to select an optimal choice. This chapter investigates what happens when decisions are made by artificial intelligent machines in the market rather than human beings. Firstly, the expectations of the future are more consistent if they are made by artificial intelligent machines than if they are made by human beings in that the bias and the variance of the error of the predictions are reduced. Furthermore, the decisions that are made are more rational and thus the marketplace becomes more rational.
