This paper proposes several tests of restricted specification in nonparametric instrumental regression. Based on series estimators, test statistics are established that allow for tests of the general model against a parametric or nonparametric specification as well as a test of exogeneity of the...

The theoretical analysis of structural changes in the context of economic growth has a long tradition. However, studies which analyze the empirical relationship between these two economic categories are still very rare. In the literature, whether growth causes structural changes or the other way...

We develop a nonparametric instrumental variable approach for the estimation of average treatment effects on hazard rates and conditional survival probabilities, without model structure.We derive constructive identification proofs for average treatment effects under noncompliance and dynamic...
