[fre] La neuroéconomie est un bel exemple d’investigation approfondie de la connaissance de l’individu. Cet outil est soutenu par l’hypothèse implicite selon laquelle « l'homme individuel » est le fameux « agent » de l'économie néoclassique. Nous soutenons ici que cette supposition...

In a recent paper in Journal of Economic Behavior and Organization, Croson (2000) shows that when subjects' beliefs about the contributions of others are elicited in a voluntary contributions public goods game, those subjects contribute less than do other subjects in the same game when beliefs...

People's beliefs about how well economic theory predicts outcomes may affect policy through democratic processes. Knowing what determines those beliefs is then important. We investigate how individual attitudes and characteristics correlate with those beliefs using a classroom Double Auction...

Disagreements about economic policy stem not just from differences in normative values, but also from differences in beliefs about which outcomes are likely. We review a selection of survey work showing this. We also report on our own work with US and Russian research subjects, which employs a...

Neuroeconomics illustrates our deepening descent into the details of individual cognition. This descent is guided by the implicit assumption that “individual human” is the important “agent” of neoclassical economics. I argue here that this assumption is neither obviously correct, nor of...

"Political economics views heterogeneity of political preferences largely as a reflection of heterogeneity in valuations of known policy outcomes. Voters, however, may be uncertain about policy outcomes, in part, because of uncertainty about how the economic world actually works. Heterogeneity...

Belief elicitation in game experiments may be problematic if it changes game play. We experimentally verify that belief elicitation can alter paths of play in a two-player repeated asymmetric matching pennies game. Importantly, this effect occurs only during early periods and only for players...

Nonconvexities undermine the efficiency of the usually robust "double auction" or DA market institution. We experimentally examine two modified DAs that allow for particularly rich bilateral contracting such as arbitrarily nonlinear pricing. The first allows for arbitrarily nonlinear pricing but...
