Description: Editorial for the October/November 2012 edition of The Actuary magazine discussing risk and uncertainty as two different concerns.

Description: “Many commentators have suggested that firms need to do stress tests to examine their vulnerability to adverse situations that are not within the data set used to parameterize their risk models. We suggest the adop¬tion of a terminology to describe stress tests and also a meth¬odology that can be adopted by any risk model user to test and communicate a test of the stability of model results.”

Description: In this article, the author examines five common perspectives on risk and see how they affect not just each participant’s own choices but everyone else’s choices, as well.

Description: Feature article discussing how ERM needs to expand to cover the many different attitudes toward risk.

Description: People naturally observe risk in the form of the range of experienced gains and losses which is usually represented in statistical terms by standard deviation. In most cases, there are not enough observed values to reliably discern the true amount of losses that are possible in extreme situations. Statistical techniques that have long been applied to insurance company risks are being used to extrapolate from observed risk to extreme tails of the distribution of gains and losses. These processes are essentially an extrapolation from the “known” risk of volatility near the mean to “unknown” risk of extreme losses. “Fat tails” is a term often applied to risks where the likely losses in rare situations significantly exceeds the predictions of a Gaussian (“thin tailed”) distribution. This paper will look at the relationship between the observed risk and the extreme risk in statistical insurance r isk models and discuss how we might create a discussion among model users about the appropriateness of that relationship for specific types of risks.

Description: This report provides highlights of a weekly survey of practices regarding the mitigation of the spread of COVID-19 in the U.S. during the final four months of 2020 and the first four months of 2021. The survey asks about the degree to which the respondents perceive that people in their community are following 21 common mitigation practices. The responses are separated by state and compared to state level statistics regarding the level of COVID-19 infections from the Johns Hopkins COVID database for the same time period.

Description: Most reasonable risk mitigation strategies provide benefit in some circumstances, but come at a cost that adversely affects results in other scenarios. A research paper by the authors considers the view of multiple stakeholders to answer this question, resulting in a process they call Trifurcation.

Description: A new reason for the inherent instability of the insurance business can be found in the literature of anthropology. The theory of plural rationalities, also known as Cultural Theory of Risk or simply Cultural Theory, posits that the world is populated by people with four fundamentally different attitudes toward risk. Presented at 2010 Enterprise Risk Management Symposium, Society of Actuaries, April 12-15, 2010.

Description: This article discusses new developments on the regulatory front. Under the new agreement, insurance company management and boards will be required to issue a statement that reflects their judgment about the firm’s viability, including its capital adequacy. The required opinion will have five elements - identifying risks, measuring risks, a risk feedback loop, a risk tolerance statement, and a risk policy.
