We study batched bandit experiments and consider the problem of inference conditional on the realized stopping time, assignment probabilities, and target parameter, where all of these may be chosen adaptively using information up to the last batch of the experiment.

We consider estimation in moment condition models and show that under any bound on identification strength, asymptotically admissible (i. e. undominated) estimators in a wide class of estimation problems must be uniformly continuous in the sample moment function.

Economists often estimate models using data from a particular domain, e. g. estimating risk preferences in a particular subject pool or for a specific class of lotteries.

We show that moment inequalities in a wide variety of economic applications have a particular linear conditional structure.
