Seção: Artigos Título: Systematic risk factors redefined / Dariusz Gatarek, Juliusz Jablecki Autor: Gatarek, Dariusz Notas: Sumario: Credit risk factor models tend to have a narrow focus on the Gaussian case, use copula functions that don't work well with the martingale methods used in pricing, and can introduce arbitrage.
