This paper introduces the concept of differential privacy (DP) as a novel technical tool that can quantifiably assess the identification #risks of #databases, thereby aiding in the classification of data. By allocating a privacy budget in advance, data controllers can establish auditable and reviewable boundaries between #personal, #anonymous, and #pseudonymous data, while integrating this framework into broader data #riskmanagement practices.

"This paper presents an intellectual exchange with #chatgpt, … , about correlation pitfalls in #riskmanagement. … Our findings indicate that ChatGPT possesses solid knowledge of basic and mostly non-technical aspects of the topic, but falls short in terms of the mathematical goring needed to avoid certain pitfalls or completely comprehend the underlying concepts."

"This paper introduces the multivariate range Value-at-Risk (MRVaR) and multivariate range covariance (MRCov) as #risk#measures for #riskmanagement in #regulation and investment… Frequently-used cases in industry, such as normal, student-t, logistic, Laplace, and Pearson type VII distributions, are presented with numerical examples."

#crisis #riskmanagement"The existing data show that #political #crises make #economiccrises crises more likely, so that, as suggested by the concept of #polycrisis, feedback between non-economic crises and economic crises can be important, but there is no comparable evidence for #climate events."

"We provide guidance on the types of applications for which consulting #chatgpt can be useful to enhance your knowledge about #quantitative #riskmanagement in #actuarial practice, and point out those for which ChatGPT should better not be invoked."

#riskmanagement#geopoliticalrisk"The frequency of economic and #financialcrises is not increasing, but #politicalcrises can make #economiccrises more likely. The paper suggests that feedback between non-economic and economic crises can be important, but there is no comparable evidence for #climaterisk."

"From a #riskmanagement perspective, it is challenging to #model physical and #transitionrisks given the #uncertainty around #climaterisk drivers, such as changes in #governmentpolicy aimed at reducing #greenhousegasemissions, the pace of technological change, and uncertainty around the transmission channels. A dearth of in-house modeling tools and reliance on #thirdparty vendors also hamper #banks’ ability to properly understand and manage #risks. The most recent #boe climate biennial exploratory scenario (#cbes) noted that “banks varied in their ability to scrutinize and understand the strengths and weakness of third-party models, and adapt them appropriately to the CBES.” As a result, projected #losses for banks varied widely, suggesting a high degree of uncertainty about the magnitude of climate risks as well as a limited ability to accurately reflect such risks in business decisions."

This paper explores potential revisions to the calculation of the #solvencyII#risk margin (RM) and contributes to the ongoing discussion by formally defining the concept of capital-on-capital cost. The paper highlights the need for practitioners to consider capital-on-capital costs in their #lifeinsurance#riskmanagement frameworks and for policymakers to carefully evaluate the potential impact of any revisions to the calculation of the RM.

This study examines the relationship between reputational events and business sustainability by assessing the effects of such events on the share prices/market capitalisations of FTSE/JSE Top 40 Index entities. Using event study methodology and Tobin’s Q ratio, the study found that reputational events are associated with significant negative cumulative average abnormal returns on the day of the event announcement and for a period thereafter, highlighting the need for listed firms to include #reputationalrisk within their #riskmanagement management frameworks and for practitioners to implement reputation management strategies.
