In this paper we study the effect of reallocating an indivisible input across a population of production units on average output. We define the Average Redistributive Effect (ARE) as the effect of such a reallocation on average output. We consider the case where inputs are discretely-valued,...

This paper develops a new efficient estimator for the average treatment effect, if selection for treatment is on observables. The new estimator is linear in the first-stage nonparametric estimator. This simplifies the derivation of the means squared error (MSE) of the estimator as a function of...
