"Semiparametric Equilibrium Counterfactuals: Emission Policies in the New and Used Car Market ", with Alexander Torgovitsky and Pietro Tebaldi

Abstract

We develop and implement a method to estimate sharp semiparametric bounds on counterfactual outcomes imposing assumptions on demand, exogeneity of instrumental variables, and supply relationships. We show that the identified set can be sharply characterized by solving a finite number of linear programs; this limits computational complexity and increases the transparency of the mapping from data and assumptions to empirical conclusions. We use this method to study how Texas vehicle emissions during the 2016-2019 period would have been different under policies to incentivize (penalize) the purchase of less (more) polluting cars.
