Diffusion coefficient estimation and asset pricing when risk premia and sensitivities are time varying


Chesney, Marc; Elliott, Robert J; Madan, Dilip B; Yang, Hailiang (1993). Diffusion coefficient estimation and asset pricing when risk premia and sensitivities are time varying. Mathematical Finance, 3(2):85-99.

Abstract

The exponential of a scalar diffusion is considered. Point estimates of the diffusion coefficient can be obtained by considering proportional increments of different powers of the exponential. an investigation of the minimum variance estimator gives unique optimal power.
