Risk Assessment of Water Distribution Service
Procedia Engineering, 2017 Abstract The paper proposes a model that evaluates the risk of a water distribution system looking to three aspects, namely; available pressure, water demand, and water quality. Three failure modes were considered for examining the risk. The risk has been defined imitating the original definition of Hashimoto's vulnerability, and expressed as the ...

Distortion Risk Measures and Discrete Risks [PDF]
In this paper we consider the problem of determining approximations for distortion risk measures of sums of non-independent random variables. First, we give an overview of the recent actuarial literature on distortion risk measures and convex bounds for ...

Modelling the joint distribution of competing risks survival times using copula functions [PDF]
, 2005 The problem of modelling the joint distribution of survival times in a competing risks model, using copula functions is considered. In order to evaluate this joint distribution and the related overall survival function, a system of non-linear ...

An investigation on the use of copulas when calculating general cash flow distributions. [PDF]
In a paper of 2000, Kaas, Dhaene and Goovaerts investigate the present value of a rather general cash flow as a special case of sums of dependent risks.

Can Artificial Intelligence Alleviate Resource Scarcity? [PDF]
, 2018 During summer 2017, I explored the implications of the potential application of artificial intelligence (AI) to resource management at the Centre for the Study of Existential Risk (CSER) at the University of Cambridge in the United Kingdom.

Uncovering the Distribution of Option Implied Risk Aversion
Journal of Mathematical Finance, 2019 This paper explores the dynamics of risk aversion of a representative agent with an iso-elastic utility function. In contrast to most of the existing literature, we estimate the coefficient of relative risk aversion from option prices. To do this, we transform the risk-neutral density function obtained from a cross-section of option prices to an ...

A new algorithm for the loss distribution function with applications to Operational Risk Management [PDF]
Operational risks inside banks and insurance companies is currently an important task. The computation of a risk measure associated to these risks lies on the knowledge of the so-called Loss Distribution Function. Traditionally this distribution function

The Bernstein-Von Mises Theorem in Semiparametric Competing Risks Models [PDF]
Semiparametric Bayesian models are nowadays a popular tool in survival analysis. An important area of research concerns the investigation of frequentist properties of these models.

Systemic Risk and Default Clustering for Large Financial Systems
, 2015 As it is known in the finance risk and macroeconomics literature, risk-sharing in large portfolios may increase the probability of creation of default clusters and of systemic risk.

Dependency of risks and stop-loss order. [PDF]
The correlation order, which is defined as a partial order between bivariate distributions with equal marginals, is shown to be a helpfull tool for deriving results concerning the riskiness of portfolios with pairwise dependencies. Given the distribution
