We apply the directed acyclic graph and spillover index models and find significant evidence of both implied volatility contagion and spillover. First, the global implied volatility smiles exhibit strong regional clustering. The European and American options markets form a separate contemporary...

This paper tests the expectations hypothesis of the term structure of implied volatility for several national stock market indexes. The tests indicate that the slope of at-the-money implied volatility over different maturities has predictive ability for future short-dated implied volatility,...
