Liquidity Risk, Credit Risk and the Overnight Interest Rate Spread : A Stochastic Volatility Modelling Approach
Beirne, John - 2010
In this paper we model the volatility of the spread between the overnight interest rate and the central bank policy … 2007. During the crisis, the policy spread exhibited signs of volatility, owing to the breakdown in interbank market … activity. The determinants of this volatility are assessed using Stochastic Volatility models to gauge the role played by …

Is market fear persistent? : a long-memory analysis
Caporale, Guglielmo Maria; Gil-Alaña, Luis A.; … - 2017
This paper investigates the degree of persistence of market fear. Specifically, two different long-memory approaches (R/S analysis with the Hurst exponent method and fractional integration) are used to analyse persistence of the VIX index over the sample period 2004-2016, as well as some...

Multi-factor Gegenbauer processes and European inflation rates
Caporale, Guglielmo Maria; Gil-Alaña, Luis A. - 2009
In this paper we specify a multi-factor long-memory process that enables us to estimate the fractional differencing parameters at each frequency separately, and adopt this framework to model quarterly prices in three European countries (France, Italy and the UK). The empirical results suggest...
