OPL: Stata module for optimal policy learning

Giovanni Cerulli

Statistical Software Components from Boston College Department of Economics

Abstract: OPL is a package for learning optimal policies from data for empirical welfare maximization. Specifically, OPL allows to find "treatment assignment rules" that maximize the overall welfare, defined as the sum of the policy effects estimated over all the policy beneficiaries. OPL learns the optimal policy empirically, i.e. based on data and observations obtained from previous (same or similar) implemented policies. OPL carries out empirical welfare maximization within three policy classes: (i) Threshold-based; (ii) Linear-combination; and (iii) Decision-tree. Empirical welfare maximization requires the estimation of the Conditional Average Treatment Effect (CATE) of the past policy. Currently, OPL estimates CATE via linear and non-linear Regression Adjustment (RA), allowing for the target outcome to be continuous, binary, count, or fractional. The treatment variable of reference must be binary 0/1.
