The changing transmission of uncertainty shocks in the US : an empirical analysis

Mumtaz, Haroon; Theodoridis, Konstantinos - 2014

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...

Dynamic effects of monetary policy shocks on macroeconomic volatility

Mumtaz, Haroon; Theodoridis, Konstantinos - 2015

Epstein-Zin preferences to study the volatility implications of a monetary policy shock. An unexpected increases in the policy … rate by 150 basis points causes output and inflation volatility to rise around 10% above their steady-state standard … deviations. VAR based empirical results support the model implications that contractionary shocks increase volatility. The …

Estimating time-varying DSGE models using minimum distance methods

Giraitis, Liudas; Kapetanios, George; Theodoridis, … - 2015

Following Giraitis, Kapetanios, and Yates (2014b), this paper uses kernel methods to estimate a seven variable time-varying (TV) vector autoregressive (VAR) model on the data set constructed by Smets and Wouters (2007). We apply an indirect inference method to map from this TV VAR to time...
