New framework extends instrumental variables to continuous-time causal inference

Researchers have developed a new framework for instrumental variable (IV) methods that can be applied to continuous-time stochastic processes. This framework addresses the challenge of identifying causal effects in systems that evolve over time, particularly when unobserved confounding factors are present. The method encodes causal effects at the infinitesimal level of the drift in stochastic differential equations and provides an identification condition and estimation method, which has been shown to outperform traditional maximum-likelihood and discrete-time IV methods in empirical tests.
