This paper extends choice theory by allowing for the interaction between cognitive costs and imitative dynamics. The authors experimentally investigate the role of imitation when participants face a task which is costly in cognitive terms. In order to disentangle different choice dynamics, they...

This paper analyzes 12,596 wagering decisions of 6,064 contestants in the US game show Jeopardy!, focusing on the anchoring phenomenon in financial decision-making. We find that contestants anchor heavily on the initial dollar value of a clue in their wagering decision, even though there exists...

We first provide evidence of some retail investors taking real trading (selling) decisions which are clearly sub-optimal even from an ex-ante perspective. We then show that these investors also exhibit stronger investment biases, namely, the disposition effect, underdiversification, preference...

The objective of this article is to investigate the presence of affect and anchoring biases in the financial decision making of individual investors. Another parallel objective is to verify whether the gender factor (male and female) or financial knowledge interfere with the presence of these...

We investigate how the anchoring effect-a well-established cognitive bias-influences the full distribution of subjective beliefs. While prior research extensively examines the impact of anchoring and other biases on point estimates, their effect on higher moments of the distribution remains...

Economic small group research points to groups as more rational decision-makers in numerous economic situations. However, no attempts have been made to investigate whether groups are affected similarly by behavioral biases that are pervasive for individuals. If groups were also able to more...

Rational ignorance and related models of voter choice have been accused of psychological implausibility or even incoherence. Although such models run counter to folk psychological understandings of choice, this paper argues that they are consistent with widely-accepted dual process theories of...
