Counterfactual Copula and Its Application to the Effects of College Education on Intergenerational Mobility
反事实 Copula 及其在大学教育与代际流动研究中的应用
This paper proposes a nonparametric estimator of the counterfactual copula of two outcome variables that would be affected by a policy intervention. The proposed estimator allows policymakers to conduct ex-ante evaluations by comparing the estimated counterfactual and actual copulas as well as their corresponding measures of association. Asymptotic properties of the counterfactual copula estimator are established under regularity conditions. These conditions are also used to…
