Recovery of Preferences from Observed Wealth in a Single Realization

Résumé du livre

Von Neumann-Morgenstern preferences over terminal consumption can be inferred from wealth on a single sample path when markets are complete and returns follow a known law in a neoclassical investment problem in either a discrete-time i.i.d. binomial model or a continuous-time diffusion model with a Gaussian state variable. Numerical results suggest that useful information about preferences can be obtained from even a single noisy sample of monthly observations of a portfolio over five years.
