We provide sufficient conditions under which a family of diffusion processes satisfies the dynamic counterparts to the famous Rothschild and Stiglitz integral conditions. We prove that the only Brownian bridge with non-constant drift that displays the Dynamic Mean-Preserving Spread (DMPS) property is given by the ballistic super-diffusive process. We illustrate our results in the context of the cannonical examples of investment under uncertainty and option pricing.}, url = {http://repository.graduateinstitute.ch/record/294127}, }
