We investigate experimentally whether social learners appreciate the redundancy of information conveyed by their observed predecessors\' actions. Each participant observes a private signal and enters an estimate of the sum of all earlier-moving participants\' signals plus her own. In a first...

This paper explains people’s preferences for ethnic and racial diversity in higher education through a model based on self interest Although all citizens from the majority group value diversity and their own education in the same way their preferences for the level of diversity as well as the...

Banning affirmative action from college admissions decisions cannot prevent an admissions office that cares about diversity from achieving it through channels other than the explicit consideration of race We construct a model of college admissions where candidates from two groups with different...

We present a field experiment to study the effects of non-monetary incentives on healthy food choices of 282 children in elementary schools. Previous interventions have typically paid participants for healthy eating, but this often may not be feasible. We introduce a system where food items are...

This paper shows how political parties differentiate to reduce electoral competition. Two parties choose platforms in a unidimensional policy space, and then candidates from these parties compete for votes in a continuum of constituencies with different median voters. Departing from their...

Good decision-making often requires people to perceive and handle a myriad of statistical correlations. Notably, optimal portfolio theory depends upon a sophisticated understanding of the correlation among financial assets. In this paper, we examine people's understanding of correlation using a...

How much information should a central bank (CB) have about (i) policy objectives and (ii) operational shocks to the effect of monetary policy? We consider a version of the Barro-Gordon credibility problem in which monetary policy signals an inflation-biased CB's private information on both these...

We generalize the canonical problem of Nash implementation by allowing agents to voluntarily provide discriminatory signals, i.e. evidence. Evidence can either take the form of hard information or, more generally, have differential but non-prohibitive costs in different states. In such...
