In this survey article, we present a rich extent of literature on volatility and its propagation on financial markets via spillovers. We document how new approaches or improved existing methodologies lead to results that offer richer insights than those derived from standard econometric...

This paper investigates the question of whether there exists evidence in support of convergence in market returns within the South American capital markets and whether these markets are becoming efficient. Both questions are analyzed using time series as well as panel data. A non-parametric...

We employ a wavelet approach and conduct a time-frequency analysis of dynamic correlations between pairs of key traded assets (gold, oil, and stocks) covering the period from 1987 to 2012. The analysis is performed on both intra-day and daily data. We show that heterogeneity in correlations...

Asymmetries in volatility spillovers are highly relevant to risk valuation and portfolio diversification strategies in financial markets. Yet, the large literature studying information transmission mechanisms ignores the fact that bad and good volatility may spill over at different magnitudes....

This paper suggests how to quantify asymmetries in volatility spillovers that emerge due to bad and good volatility. Using data covering most liquid U.S. stocks in seven sectors, we provide ample evidence of the asymmetric connectedness of stocks at the disaggregate level. Moreover, the...
