The subject of this paper is how the epistemic limitations of individuals and their biases in reasoning affect collective decisions and in particular the functioning of democracies. In fact, while the cognitive sciences have largely shown how the imperfections of human rationality shape...

Time is a crucial determinant of deception, since some misreporting opportunities come as a surprise and require an intuitive decision while others allow for extensive reflection time. To be able to pursue a deceptive strategy, however, a subject must be aware of the misreporting opportunity....

We designed four observational learning experiments to identify the key channels that, along with Bayes-rational inferences, drive herd behavior. In Experiment 1, unobserved, whose actions remain private, learn from the public actions made in turn by subjects endowed with private signals of...

This paper studies the relevance of cognitive uncertainty - subjective uncertainty over one’s utility-maximizing action - for understanding and predicting intertemporal choice. The main idea is that when people are cognitively noisy, such as when a decision is complex, they implicitly treat...

Algorithm-based decision support systems play an increasingly important role in decisions involving exploration tasks, such as product searches, portfolio choices, and human resource procurement. These tasks often involve a trade-off between exploration and exploitation, which can be highly...

The mathematical framework of psychological game theory is useful for describing many forms of motivation where preferences depend directly on own or others’ beliefs. It allows for incorporating, e.g., emotions, reciprocity, image concerns, and self-esteem in economic analysis. We explain how...

To discuss experimental results without discussing how they came about makes sense when the results are robust to the way experiments are conducted. Experimental results, however, are - arguably more often than not - sensitive to numerous design and implementation characteristics such as the use...

Duverger (1954) noted that changes in electoral systems will have two types of effects: mechanical effects, and reactions of political agents in anticipation of these, which he referred to as psychological effects. It is complicated to empirically separate the two effects since these occur...

Economic research shows that candidates have a higher chance of getting (re-)elected when they have the luck that the world economy does well even though this is beyond their control and unrelated to their competence. Psychological research demonstrates that candidates increase their chances if...

We propose a model of optimal decision making subject to a memory constraint. The constraint is a limit on the complexity of memory measured using Shannon's mutual information, as in models of rational inattention; but our theory differs from that of Sims (2003) in not assuming costless memory...
