In this study, we apply a rolling window approach to wavelet-filtered (denoised) S&P500 returns (2000–2020) to obtain time varying Hurst exponents. We analyse the dynamics of the Hurst exponents by applying statistical tests (e.g., for stationarity, Gaussianity and self-similarity), a...

This paper examines how the implementation of a new dark order - Midpoint Extended Life Order on NASDAQ - impacts financial markets stability in terms of occurrences of mini-flash crashes in individual securities. We use high-frequency order book data and apply panel regression analysis to...

Do rating agencies increase or decrease financial market stability? This paper analyzes whether credit rating agencies may help to avoid inefficient self-fulfilling credit defaults. If investors follow risk-dominant strategies, we show that rating announcements and investors' private information...

Focusing on five major emerging markets (EM), I investigate the interactions between credit default swap (CDS) premiums, foreign exchange (FX) parities, local currency government bond (LCB) spreads, and national stock market indices over the period 4/2/2007 to 8/27/2009. Empirical analysis...

A new test for financial market contagion based on changes in extremal dependence defined as co-kurtosis and co-volatility is developed to identify the propagation mechanism of shocks across international financial markets. The proposed approach captures changes in various aspects of the asset...

A new test for financial market contagion based on increases in extremal dependence (co-kurtosis and co-volatility) is developed to identify the propagation mechanism of shocks across international financial markets. This new approach is applied to test for contagion in equity markets and...

This paper considers the role of foreign investors in developed-country equity markets. It presents a quantitative model of trading that is built around two new assumptions: (i) both the foreign and domestic investor populations contain investors of different sophistication, and (ii) investor...

This paper reconsiders the role of foreign investors in developed country equity markets. It presents a quantitative model of trading that is built around two new assumptions about investor sophistication: (i) both the foreign and domestic populations contain investors with superior information...

The global financial crisis of 2008 was a crisis affecting both the financial sector and the “real economy.” This paper analyzes the transmission of unexpected shocks from the financial sector in the US to other countries and sectors. We test the hypothesis that the financial crisis spread...

This paper analyzes the incidences of sector-specific contagion during the Global Financial Crisis of 2007-2009. The empirical analysis comprising ten sectors in 25 major developed and emerging stock markets shows that the crisis led to an increased co-movement of returns and thus contagion...
