"Cyber attacks can impair banks operations and precipitate bank runs. When digital infrastructure is shared, banks defend themselves by investing in cybersecurity but can free-ride on the security measures of others. Ex ante free-riding by banks interacts with the ex post coordination frictions underpinning bank runs."
"This study is the first to comprehensively investigate the five lines of accountability as opposed to single lines in the theoretical context of institutional theory. It provides several implications for practice."
"The analysis discusses the overall negotiations process underpinning Brexit and examines the key resulting regimes, including the Trade and Cooperation Agreement (TCA) and the EU-UK data adequacy agreements granted under the GDPR and the LED."
"We ... present a simple sufficient condition for monotone comparative statics of changes in risk under risk aversion."
"We... apply two stochastic orders to some classic decision problems in economics and finance including a portfolio problem, two insurance problems, and four management decision problems and present a simple sufficient condition for monotone comparative statics of changes in risk under risk aversion."
"…. the surplus of an insurance company is routinely approximated by a Brownian motion, as opposed to the geometric Brownian motion used to model assets in finance. Furthermore, exposure to risk is controlled "downwards" via reinsurance, rather than "upwards" via risky investments. This leads to interesting qualitative differences in the optimal solutions."
"...we argue that... the median shortfall—that is, the median of the tail loss distribution—is a better option than the expected shortfall for setting the Basel Accords capital requirements due to statistical and economic considerations such as capturing tail risk, robustness, elicitability, backtesting, and surplus invariance."
"Unlike the existing parametric approaches, our method is simple yet flexible to encapsulate distributional dependence structures of bivariate outcomes and covariates. Various simulation results confirm that our method can perform similarly or better in finite samples compared to the alternative methods."
"The Gerber-Shiu function provides a unified framework for the evaluation of a variety of risk quantities. Ever since its establishment, it has attracted constantly increasing interests in actuarial science, whereas the conventional research has been focused on finding analytical or semi-analytical solutions, either of which is rarely available, except for limited classes of penalty functions on rather simple risk models."
"Using a sample of bank holding companies over the period 2015Q1 through 2020Q1, we find that risk exposure increases for the large banks that benefitted from the removal of certain regulatory provisions. These banks also benefit from higher profitability and reduced compliance costs."
