Due to a legal challenge, there was a staggered introduction of fast track debt recovery tribunals (DRTs) across the states of India in the 1990s. Exploiting this plausibly exogenous variation in the efficiency of debt contract enforcement and using detailed information on product lines produced...

We provide an adversarial approach to estimating Riesz representers of linear functionals within arbitrary function spaces. We prove oracle inequalities based on the localized Rademacher complexity of the function space used to approximate the Riesz representer and the approximation error. These...
