Abstract: We develop a nonparametric estimation method and inferential theory for the state-varying factor-augmented vector autoregressive (FAVAR) models, in which both the factor loadings and the FAVAR coefficients vary as general functions of a stochastic state process. Our two-stage estimation procedure combines the local principal component analysis and nonparametric kernel regressions, and we establish the limiting distribution theory for the estimators of the state-varying FAVAR coefficients. We also study the construction of impulse response functions (IRFs) in the state-varying FAVAR models and show the consistency of the estimators of IRFs. In addition, we propose three test statistics to gauge the possible sources of state-dependency features in the underlying FAVAR model. The simulation results indicate that our estimators and test statistics perform well in finite samples. In the empirical study, we apply the state-varying FAVAR model to investigate the monetary policy transmission mechanism and IRFs using the U.S. data.
