I propose a general alethic theory of epistemic risk according to which the riskiness of an agent’s credence function encodes her relative sensitivity to different types of graded error. After motivating and mathematically developing this approach, I show that the epistemic risk function is a scaled reflection of expected inaccuracy (a quantity also ...

Theory of Generalized Risk Attitudes
Decision Analysis, 2015This paper develops a theory of risk attitudes that can be applied in a broad array of settings, including those in which the decision maker (DM) abides by a preference model other than the expected utility model and in which decisions are being made over multiattribute alternatives. The theory is based on (i) a set of plausible axioms in which the DM’

I hope that you will bear with me because I am just one of these statisticians who does not know anything about business and industry and, consequently, it is perfectly obvious that my approach is rather an academic one. However, I have come here to talk to a document which you now have in front of you, and I would like to work through it and talk a ...

Liquidity risk theory and coherent measures of risk
Quantitative Finance, 2007We discuss liquidity risk from a pure risk-theoretical point of view in the axiomatic context of coherent measures of risk. We propose a formalism for liquidity risk that is compatible with the axioms of coherency. We emphasize the difference between ‘coherent risk measures’ (CRM) ρ(X ) defined on portfolio values X as opposed to ‘coherent portfolio ...

Decision Theory and Surgical Risk
Methods of Information in Medicine, 1974Reliability on the automatic prediction of the outcome in arterial reconstructive surgery was evaluated with the aid of a computer program based on decision theory. Twenty items of information were collected from 92 patients and used as predictors. Accuracy of the computerized allocation was checked by simple reclassification.

Information assurance is more of a goal than a reality today. IA is all about mitigating risks to information and information systems. This chapter will define and discuss the theory of risk, risk assessment, risk management, threats, and vulnerabilities and integrating risk concepts into an IA program.

Journal of the Institute of Actuaries, 1970
All business is, to a greater or lesser extent, concerned with the taking of risk. This paper attempts to explain some of the main approaches that have been adopted in pursuing the concept of risk from a probabilistic viewpoint. The word ‘risk’ itself has been used fairly indiscriminately by writers, and thus gets given a number of different senses ...

Absolute risk aversion (R A ) and relative risk aversion (R R ). u(y) is a utility function, y is income, or consumption. A characterization of utility functions with constant absolute and relative risk aversion, respectively. A1 and A2 are constants, A2 ≠ 0. Risk aversions for two special utility functions.
