In this paper, we study the Kelly criterion in the continuous time framework building on the work of E.O. Thorp and others. The existence of an optimal strategy is proven in a general setting and the corresponding optimal wealth process is found. A simple formula is provided for calculating the...

A new framework for asset price dynamics is introduced in which the concept of noisy information about future cash flows is used to derive the corresponding price processes. In this framework an asset is defined by its cash-flow structure. Each cash flow is modelled by a random variable that can...

Bayes criteria are explicitly applied to statistical decision problems in simple quantum mechanical systems. The minimum Bayes cost is calculated for systems including polarised spins and relativistic spin 12 particles. The results suggest that, in decisions for a given ensemble of particles, on...
