Time-Varying Jump Tails ∗

  title={Time-Varying Jump Tails ∗},
  author={Tim Bollerslev and Viktor Todorov},
We develop new methods for the estimation of time-varying risk-neutral jump tails in asset returns. In contrast to existing procedures based on tightly parameterized models, our approach imposes much fewer structural assumptions, relying on extreme-value theory approximations together with short-maturity options. The new estimation approach explicitly… CONTINUE READING
