A condition for the identification of multivariate models with binary instruments -- with Corrigendum and Addendum
Florian Gunsilius
This article introduces an empirical condition for the nonparametric point-identification of multivariate instrumental variable models with continuous endogenous variables using bi…
A path-sampling method to partially identify causal effects in instrumental variable models
Florian Gunsilius
Partial identification approaches are a flexible and robust alternative to standard point-identification approaches in general instrumental variable models. However, this flexibili…
Point-identification in multivariate nonseparable triangular models
Florian Gunsilius
In this article we introduce a general nonparametric point-identification result for nonseparable triangular models with a multivariate first- and second stage. Based on this we pr…
Non-testability of instrument validity under continuous endogenous variables
Florian Gunsilius
This note presents a proof of the conjecture in \citet*{pearl1995testability} about testing the validity of an instrumental variable in hidden variable models. It implies that inst…
