Local Asymptotics for Treatment Choice with Partial Identification

José Luis Montiel Olea, Chen Qiu, Jörg Stoye

We provide a new asymptotic framework to derive approximately optimal treatment assignments when sampling noise from data is compounded by fundamental uncertainty due to partial id…

Statistical Decisions and Partial Identification: With Application to Boundary Discontinuity Design

Chen Qiu, Jörg Stoye

We are delighted to respond to the excellent surveys by Cattaneo et al. (2026) and Hirano (2026). Our discussion will attempt two things: first, we show how statistical decision th…

Epsilon-Minimax Solutions of Statistical Decision Problems

Andrés Aradillas Fernández, José Blanchet, José Luis Montiel Olea +3

A decision rule is epsilon-minimax if it is minimax up to an additive factor epsilon. We present an algorithm for provably obtaining epsilon-minimax solutions for a class of statis…

Robust Bayes Treatment Choice with Partial Identification

Andrés Aradillas Fernández, José Luis Montiel Olea, Chen Qiu +2

We study a class of binary treatment choice problems with partial identification through the lens of robust (multiple prior) Bayesian analysis. We use a convenient set of prior dis…

Approximate Least-Favorable Distributions and Nearly Optimal Tests via Stochastic Mirror Descent

Andrés Aradillas Fernández, José Blanchet, José Luis Montiel Olea +3

We consider a class of hypothesis testing problems where the null hypothesis postulates distributions for the observed data, and there is only one possible distribution under t…

Externally Valid Selection of Experimental Sites via the k-Median Problem

José Luis Montiel Olea, Brenda Prallon, Chen Qiu +2

We present a decision-theoretic justification for viewing the question of how to best choose where to experiment in order to optimize external validity as a -median problem, a p…
