The current paper studies equity markets for the contagion of squared index returns as a proxy for stock market volatility, which has not been studied earlier. The study examines squared stock index returns of equity in 35 markets, including the US, UK, Euro Zone and BRICS (Brazil, Russia,...

This paper presents a tractable model of non-linear dynamics of market returns using a Langevin approach.Due to non-linearity of an interaction potential, the model admits regimes of both small and large return fluctuations. Langevin dynamics are mapped onto an equivalent quantum mechanical (QM)...

In this paper we realize an early warning system for hedge funds based on specific red flags that help to detect symptoms of impending extreme negative returns and contagion effect. To do this we rely on regression trees analysis identifying a series of splitting rules which act as risk signals....

The September 2008 collapse of Lehman Brothers was the 9/11 on Wall Street, and many articles had been written on the changes in the global risk landscape that followed. However, there is scarcity of rigorous studies using empirical data and advanced econometric methods to verify such a change...

The objective of this paper is to estimate the relative contribution of a wide array of determinants to outbreak of financial crises in the EU candidate countries (Croatia, Macedonia and Turkey) and to identify the best-performing early warning indicators of financial crises. We have estimated a...

We propose a novel time-changed L évy LIBOR market model for the joint pricing of caps and swaptions. The time changes are split into three components. The first component allows us to match the volatility term structure, the second generates stochastic volatility, and the third one...

This paper explores intraday dynamics of the CAC 40 index futures market and the underlying spot in the light of the financial crisis. The GJR-GARCH model shows a decrease (increase) of the futures market volatility (spot market) during the crisis. Contrary to the spot index, we find no evidence...

We construct a network-based turbulence score that proves useful for analyzing the relationship between financial interconnectedness, and global market risk, and for identifying systemically important markets, with the highest contribution to financial turbulence. We apply our measure to study...

This paper proposes a stochastic volatility model to measure sovereign financial distress. It examines howkey European sovereign credit default swap (CDS) spreads affect each other; specifically, the paperanalyses the volatility structure of Germany, Greece, Ireland, Italy, Spain and Portugal....
