Privately, the most profitable human use of biomass is widespread monoculture, which creates large target hosts that invite potentially lethal pathogens. In analyzing the tradeoffs, I explain how the famous formula for ecological entropy, H'= -E qj log qj, can be given a mathematically rigorous...

This paper proposes a Bayesian method of performance evaluation for investment managers. We begin with a flexible set of prior beliefs that can be elicited without any reference to probability distributions or their parameters. We then combine these prior beliefs with a general multi-factor...
