On idiosyncratic stochasticity of financial leverage effects

  • Carles Bret\'o
Registered author(s):

    We model leverage as stochastic but independent of return shocks and of volatility and perform likelihood-based inference via the recently developed iterated filtering algorithm using S&P500 data, contributing new evidence to the still slim empirical support for random leverage variation.
