“…However, the pricing improvements are not robust and exhibit biases for the deepest out-of-the-money call options. Deterministic volatility models have also been considered (Dupire, 1994, Rubinstein, 1994, but Dumas et al (1998) reported that the same performance could be achieved by applying an implied volatility smoothing procedure on the Black-Scholes model. Augmenting the underlying price process can produce many different variants of the Black-Scholes model.…”

“…Dumas et al (1998) find that estimated parameters are highly unstable over time, allowing only for short time predictions. As Poon and Granger (2003) point out, classical time series-based methods do not perform well in predicting volatility.…”

“…Furthermore, the countercyclical MPR can be generated from simple microeconomic assumptions about individual agents' preferences. 28 Since this study is the first to introduce the rate of macroeconomic fluctuation, there are no empirical data about the behavior of ρ t . We believe this is an important question deserving a serious empirical analysis.…”
