The random utility model (RUM, McFadden and Richter (1990)) has been the standard tool to describe the behavior of a … heterogeneity. We apply this methodology in a novel stochastic choice data set that we collected in a large‐scale online experiment …. Our data set is unique since it exhibits both choice set and (attention) frame variation. We run a statistical survival …

We present a novel characterization of random rank-dependent expected utility for finite datasets and finite prizes. As … a byproduct, we obtain a characterization of random expected utility that works for finite datasets. The test lends … itself to statistical testing. We apply our test to an experimental dataset and find evidence against random expected utility …

We report on two novel choice experiments with real goods where subjects in one treatment are forced to choose, as is … the norm in economic experiments, while in the other they are not but can instead incur a small cost to defer choice … by rational choice. Our results suggest that nonforced‐choice experiments and models can be helpful in separating people …
