Multivariate Jump Diffusion Model with Markovian Contagion
de Carvalho, Pablo Jose Campos - 2017
Asset prices exhibit characteristics that significantly deviate from log-normality and display time-varying stochastics. There is ample evidence of jumps in one asset price or market leading to jumps in other assets' prices or markets. We propose a multivariate jump diffusion model with...
