Researchers have developed a novel instrumental variable (IV) framework designed to address causal questions in continuous-time stochastic processes. This new method extends traditional IV techniques, which are typically applied in static or discrete-time settings, to handle unobserved confounding in systems governed by stochastic differential equations (SDEs). The framework encodes causal effects at the infinitesimal level of the drift and derives moment restrictions using path-valued instruments, simplifying for specific processes like Ornstein-Uhlenbeck. The approach has demonstrated empirical success in recovering causal effects in confounded continuous-time systems where other methods have shown bias. AI
