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...

Does higher import competition increase formalization and aggregate productivity? Exploiting plausibly exogenous variation from Chinese imports, we provide empirical causal evidence that higher imports increases the share of formal manufacturing enterprise employment in India. This formal share...
