In this paper we extend the Bayesian Proxy VAR to incorporate time variation in the parameters. A Gibbs sampling algorithm is provided to approximate the posterior distributions of the model's parameters. Using the proposed algorithm, we estimate the time-varying effects of taxation shocks in...

A growing empirical literature has considered the impact of uncertainty using SVAR models that include proxies for uncertainty shocks as endogenous variables. In this paper we consider the possible impact of measurement error in the uncertainty shock proxies on the estimated impulse responses...

This paper investigates if the impact of uncertainty shocks on the US economy has changed over time. To this end, we develop an extended Factor Augmented VAR model that simultaneously allows the estimation of a measure of uncertainty and its time-varying impact on a range of variables. We find...

In this paper, we assess how risk-sharing channels have evolved over time in the United States and the Euro Area, and whether they have operated as "complements" or "substitutes". In particular, we focus on the capital channel (income from cross-border ownership of productive assets), the credit...

This paper uses structural vector autoregressive models (SVARs) to show that the response of US stock prices to fiscal shocks changed in 1980. Over the period 1955-1979, an expansionary spending or revenue shock was associated with higher stock prices. After 1980, the response of stock prices to...

This paper studies the dynamic response of labour input to neutral technology shocks. It uses a standard real business cycle model enriched with labour market search and matching frictions and investment-specific technological progress that enables a new, agnostic, identification scheme based on...

We confirm that standard time-series models for US output growth, inflation, interest rates and stock market returns feature non-Gaussian error structure. We build a 4-variable VAR model where the orthogonolised shocks have a Student t-distribution with a time-varying variance. We find that in...
