Changing impact of shocks : a time-varying proxy SVAR approach

Mumtaz, Haroon; Petrova, Katerina - 2018

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...

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 …

Measuring the origins of macroeconomic uncertainty

Mumtaz, Haroon - 2018

This paper extends the procedure developed by Jurado et al. (2015) to allow the estimation of measures of uncertainty that can be attributed to specific structural shocks. This enables researchers to investigate the "origin" of a change in overall macroeconomic uncertainty. To demonstrate the...

Financial conditions and density forecasts for US output and inflation

Alessandri, Piergiorgio; Mumtaz, Haroon - 2014

When do financial markets help in predicting economic activity? With incomplete markets, the link between financial and real economy is state-dependent and financial indicators may turn out to be useful particularly in forecasting "tail" macroeconomic events. We examine this conjecture by...
