An Investment and Consumption Problem with CIR Interest Rate and Stochastic Volatility
Abstract and Applied Analysis, 2013 We are concerned with an investment and consumption problem with stochastic interest rate and stochastic volatility, in which interest rate dynamic is described by the Cox-Ingersoll-Ross (CIR) model and the volatility of the stock is driven by Heston’s ...
