چکیده
We estimate a model of strategic voting with incomplete information in which committee members – judges in the US courts of appeals – have the opportunity to communicate before casting their votes. The model is characterized by multiple equilibria, and partial identification of model parameters. We obtain confidence regions for these parameters using a two-step estimation procedure that allows flexibly for characteristics of the alternatives and the individuals. To quantify the effects of deliberation on outcomes, we compare the probability of mistakes in the court with deliberation with a counterfactual of no pre-vote communication. We find that for most configurations of the court in the confidence set, in the best case scenario deliberation produces a small potential gain in the effectiveness of the court, and in the worst case it leads to large potential losses.

An Experimental Study of Jury Deliberation
We study the e¤ects of deliberation on collective decisions. In a series of experiments, we vary groupspreference distributions (between common and conicting interests) and the institutions by which decisions are reached (simple majority, two-thirds majority, and unanimity). When deliberation is prohibited, di¤erent institutions generate signi cantly di¤erent outcomes, tracking the theoretica...

My goals in this paper are: (i) To give a pithy, opinionated summary of what has been learned about bounded rationality in individual decision making from experiments in economics and psychology (drawing on my 1995 Handbook of Experimental Economics chapter); and (ii) mention some promising new directions for research which would be included if that chapter were

متن کاملNber Working Paper Series Experimenting with Measurement Error: Techniques with Applications to the Caltech Cohort Study
Measurement error is ubiquitous in experimental work. It leads to imperfect statistical controls, attenuated estimated effects of elicited behaviors, and biased correlations between characteristics. We develop simple statistical techniques for dealing with experimental measurement error. These techniques are applied to data from the Caltech Cohort Study, which conducts repeated incentivized sur...
