“…Hence we need to use economic models and/or econometric methods to transform risk-neutral densities into real-world 3 densities. Economic theory motivates pricing kernel transformations using power and/or exponential utility functions (Bakshi, Kapadia, & Madan, 2003;Bliss & Panigirtzoglou, 2004;Liu, Shackleton, Taylor, & Xu, 2007) and the hyperbolic absolute risk aversion (HARA) function (Kang & Kim, 2006). Liu et al (2007) use both utility and statistical calibration transformations, and they find that a statistical, parametric calibration gives a higher log-likelihood for observed outcomes than a utility transformation.…”
