Why Philosophers Should Care About Computational Complexity [PDF]
, 2011 One might think that, once we know something is computable, how efficiently it can be computed is a practical question with little further philosophical importance. In this essay, I offer a detailed case that one would be wrong.

Mutual fund director compensation
Journal of Financial Research, EarlyView.Abstract We examine director compensation using a large sample of hand‐compiled U.S. mutual fund data. We find that director compensation is positively correlated with observable productive characteristics—workload, experience, and demographics—that capture the benefits from the directors’ monitoring effort.

Quantum mechanics as a theory of probability [PDF]
, 2005 We develop and defend the thesis that the Hilbert space formalism of quantum mechanics is a new theory of probability. The theory, like its classical counterpart, consists of an algebra of events, and the probability measures defined on it.

Price Indices Rekindled, 1970s–1990s: Theory and Practice at Cross Purposes?
Journal of Economic Surveys, EarlyView.ABSTRACT This paper revisits the discussions on price indices during a period marked by theoretical advancements and practical challenges in measuring inflation. Index‐number theorists sought to improve accuracy, yet national statistical offices largely maintained established practices due to concerns over data availability, stability, and public trust.

Expected Shortfall: a natural coherent alternative to Value at Risk
, 2001 We discuss the coherence properties of Expected Shortfall (ES) as a financial risk measure. This statistic arises in a natural way from the estimation of the "average of the 100p % worst losses" in a sample of returns to a portfolio. Here p is some fixed

Model Ambiguity versus Model Misspecification in Dynamic Portfolio Choice
The Journal of Finance, EarlyView.ABSTRACT We study aversion to model ambiguity and misspecification in dynamic portfolio choice. Risk‐averse investors (relative risk aversion γ>1$\gamma > 1$) fear return persistence, while risk‐tolerant investors (0<γ<1$0<\gamma <1$) fear mean reversion, when confronting model misspecification concerns of identically and independently distributed (IID)

Nature, Science, Bayes' Theorem, and the Whole of Reality [PDF]
, 2015 A fundamental problem in science is how to make logical inferences from scientific data. Mere data does not suffice since additional information is necessary to select a domain of models or hypotheses and thus determine the likelihood of each model or ...
