Research and Approval Process: The Organization of Persuasion
Emeric Henry and Marco Ottaviani

American Economic Review, forthcoming

Organizational deconstruction of Wald's model of sequential information acquisition, bridging experimentation with persuasion. The payoff and control rights of a statistician (planner) are split between an evaluator and an informer. The informer provides costly information with the aim of persuading the evaluator to approve. Welfare analyis + application to approval regulation, including FDA's supervision of clinical trials.

Looking into Crystal Balls: An Experiment on Reputational Cheap Talk
Debrah Meloso, Marco Ottaviani, and Salvatore Nunnari

Do expert motivated by their reputation for being well informed have an incentive to misreport their information? As predicted by reputational cheap talk theory, reporters are more likely to report truthfully when the state of the world is more uncertain and when evaluators conjecture that reporters always report truthfully. However, evaluators have difficulty learning reporters' strategies and tend to overreact to message accuracy, exacerbating reporters' incentives to misreport.
