Published / Preprint: Double-jump stochastic volatility model for VIX: evidence from VVIX. (arXiv:1506.07554v1 [q-fin.CP])

Posted: 25 Jun 2015 05:38 PM PDT

The paper studies the continuous-time dynamics of VIX with stochastic volatility and jumps in VIX and volatility. Built on the general parametric a?ne model with stochastic volatility and jump in logarithm of VIX, we derive a linear relation between the stochastic volatility factor and VVIX index. We detect the existence of co-jump of VIX and VVIX and put forward a double-jump stochastic...

Published / Preprint: Too dynamic to fail. Empirical support for an autocatalytic model of Minsky's financial instability hypothesis. (arXiv:1506.07582v1 [q-fin.GN])

Posted: 25 Jun 2015 05:38 PM PDT

Solomon and Golo [1] have recently proposed an autocatalytic (self-reinforcing) feedback model which couples a macroscopic system parameter (the interest rate), a microscopic parameter that measures the distribution of the states of the individual agents (the number of firms in financial difficulty) and a peer-to-peer network effect (contagion across supply chain financing). In this model, each...

Published / Preprint: A Bayesian Model of the Litigation Game. (arXiv:1506.07854v1 [q-fin.EC])

Over a century ago, Oliver Wendell Holmes invited scholars to look at the law through the lens of probability theory: "The prophecies of what the courts will do in fact, and nothing more pretentious, are what I mean by the law." Yet few legal scholars have taken up this intriguing invitation. As such, in place of previous approaches to the study of law, this paper presents a...

Blog Post: WealthandCapitalMarketsBlog: Looking beyond 'Bondificationâ

Posted: 25 Jun 2015 08:47 AM PDT

There has been an interesting article in the Financial Times by John Authers on the ‘bondification” of the equity markets, namely the tendency for fund managers to invest in good dividends, low debt and high return on equity. Some of the causes of this phenomenon include the low interest rate regime in many of the mature markets such as the US and the tendency for high risk aversion...

Blog Post: NumericalAlgorithmsGroup: Helping primary school children achieve the best in their SATs

Posted: 25 Jun 2015 04:26 AM PDT

My wife Caroline is a teacher in a primary school near where we live in Buckinghamshire. She teaches year 6, that is to say, ten to eleven year old children. Now, year 6 is a rather important year in British schools. Children following the National Curriculum in state-funded schools are subject to SATs (standard assessment tests) before they move on to secondary school, and the results of these...
