In this paper, we propose a kernel-type estimator for the local characteristic function of locally stationary processes. Under weak moment conditions, we prove joint asymptotic normality for local empirical characteristic functions. For time-varying linear processes, we establish a central limit...

This study focuses on the role of heterogeneity in network peer effects by accounting for network-specific factors and different driving mechanisms of peer behavior. We propose a novel Multivariate Instrumental Variable (MVIV) estimator which is consistent for a large number of networks keeping...

Understanding the monetary policy transmission mechanism is pivotal for the design of an effective monetary policy. In this regard, the coexistence of interest rate and cost channel of monetary policy has raised important implications for the conduct of monetary policy. This article estimates a...
