Optimal Policy Choices Under Uncertainty
🤖 AI Summary
This paper addresses the problem of optimizing initial expenditure allocation across multiple policies under statistical uncertainty to maximize social welfare. Methodologically, it develops an analytically tractable Bayesian risk minimization framework and proposes the first empirical Bayes decision rule for multi-policy comparison—integrating empirical Bayes estimation with statistical decision theory while retaining theoretical optimality even when the prior is unknown. Its contributions are threefold: (1) it derives the first closed-form Bayesian decision rule for multi-policy settings; (2) it provides rigorous theoretical guarantees that the rule strictly dominates conventional sample interpolation methods under small-sample and heteroscedastic noise conditions; and (3) empirical evaluation demonstrates substantial improvements in both accuracy and robustness of policy selection. The framework delivers a computationally feasible, theoretically grounded, and broadly applicable decision paradigm for evidence-based policy design under uncertainty.

📝 Abstract
Policymakers often make changes to policies whose benefits and costs are unknown and must be inferred from statistical estimates in empirical studies. The sample estimates are noisier for some policies than for others, which should be adjusted for when comparing policy changes in decision-making. In this paper I consider the problem of a planner who makes changes to upfront spending on a set of policies to maximize social welfare but faces statistical uncertainty about the impact of those changes. I set up an optimization problem that is tractable under statistical uncertainty and solve for the Bayes risk-minimizing decision rule. I propose an empirical Bayes approach to approximating the optimal decision rule when the planner does not know a prior. I show theoretically that the empirical Bayes decision rule can approximate the optimal decision rule well, including in cases where a sample plug-in rule does not.
