Subdiffusive option price model with inverse Gaussian subordinator
Shchestyuk, Nataliya; Tyshchenkob, Sergii - 2024
The paper focuses on the option price subdiffusive model under the unusual behavior of the market, when the price may not be changed for some time which is quite a common situation in the modern financial markets or during global crises. In the model, the risk-free bond motion and classical GBM...

Large vector autoregressions with asymmetric priors
Carriero, Andrea; Clark, Todd E.; Marcellino, Massimiliano - 2015 - This draft: November 2015
We propose a new algorithm which allows easy estimation of Vector Autoregressions (VARs) featuring asymmetric priors and time varying volatilities, even when the cross sectional dimension of the system N is particularly large. The algorithm is based on a simple triangularisation which allows to...

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 …

Common and country specific economic uncertainty
Mumtaz, Haroon; Theodoridis, Konstantinos - 2015
We use a factor model with stochastic volatility to decompose the time-varying variance of Macro economic and Financial … component plays an important role in driving the time-varying volatility of nominal and financial variables. The cross …-country co-movement in volatility of real and financial variables has increased over time with the common component becoming more …

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...
