报告摘要：
This paper models the joint dynamics of macro aggregates and functional variables within the Structural VAR framework. I reduce the dimension of the system using functional PCA and show that the proposed functional VAR (FVAR) consistently recovers the responses of the functions. The FVAR is easy to implement and fully compatible with conventional SVAR tools. Simulation evidence shows that it performs satisfactorily in finite samples. Applying FVAR to study the impact of tax shocks on income distributions in the UK, I find that tax cuts persistently reduce the density of lower-middle-class households, which is offset by a substantial increase in the richer range and a moderate increase in the poorer range. However, this pattern is not captured by VARs with conventional inequality measures.
