Moment Forests

Working Papers

We propose a new methodology, moment forests, that allows parameters in a broad class of moment-based models to vary across groups of observations on the basis of observable characteristics. Leveraging a generalization of classification trees, the estimator first assigns observations to disjoint subgroups sharing common parameters, and then estimates an empirical model within each group. We prove the uniform consistency of this estimator and show that standard rates of convergence apply to the second stage estimates under weak regularity conditions. We showcase our approach by estimating heterogeneous treatment effects in a regression discontinuity design in a development setting.
