Experimental research on decision making under risk has until now always employed choice data in order to evaluate the empirical performance of expected utility and the alternative nonexpected utility theories. The present paper performs a similar analysis which relies on pricing data instead of...

We show that far from capturing a formally new phenomenon, informational herding is really a special case of single-person experimentation ­ and 'bad herds' the typical failure of complete learning. We then analyze the analogous team equilibrium, where individuals maximize the present...

We prove that the recently proposed informational herding models are but special cases of a standard single person experimentation model with myopia. We then re-interpret the incorrect herding outcome as a familiar failure of complete learning in a optimal experimentation problem. We next...
