Identifying shocks via time-varying volatility
Lewis, Daniel J. - 2018
An n-variable structural vector auto-regression (SVAR) can be identified (up to shock order) from the evolution of the … process. I propose a new identification argument that identifies the SVAR up to shock orderings using the autocovariance … structure of second moments of the residuals implied by an arbitrary stochastic process for the shock variances. These higher …

Chapter 20. Term Structure of Uncertainty in the Macroeconomy
Borovička, J.; Hansen, L.P. - In: Handbook of macroeconomics : volume 2, v. 2A-2B SET, (pp. 1641-1696). 2016
Dynamic economic models make predictions about impulse responses that characterize how macroeconomic processes respond to alternative shocks over different horizons. From the perspective of asset pricing, impulse responses quantify the exposure of macroeconomic processes and other cash flows to...

The response of stock market volatility to futures-based measures of monetary policy shocks
Gospodinov, Nikolaj; Jamali, Ibrahim - 2014
In this paper, we investigate the dynamic response of stock market volatility to changes in monetary policy. Using a … vector autoregressive model, our findings reveal a significant and asymmetric response of stock returns and volatility to … monetary policy shocks. Although the increase in the volatility risk premium, futures-trading volume, and leverage appear to …

Structural vector autoregressions with smooth transition in variances : the interaction between US monetary policy and the stock market
Lütkepohl, Helmut; NetŠunajev, Aleksei - 2014
In structural vector autoregressive analysis identifying the shocks of interest via heteroskedasticity has become a standard tool. Unfortunately, the approaches currently used for modelling heteroskedasticity all have drawbacks. For instance, assuming known dates for variance changes is often...

Testing for identification in SVAR-GARCH models : reconsidering the impact of monetary shocks on exchange rates
Lütkepohl, Helmut; Milunovich, George - 2015
Changes in residual volatility in vector autoregressive (VAR) models can be used for identifying structural shocks in a … structural VAR analysis. Testable conditions are given for full identification for the case where the volatility changes can be …
