Researchers have developed a novel nonlinear structural vector autoregressive framework that can identify structural shocks even when the contemporaneous mapping is nonlinear and non-additive. This identification is achieved by leveraging variations in conditional shock distributions induced by exogenous variables, using a general contrastive learning framework. The framework is implemented in an R package called iiasvar and has been applied to study asymmetries in U.S. industrial production responses to oil price shocks, revealing modest asymmetries. AI
