Assessing Financial Model Risk [PDF]

open access: yesEuropean Journal of Operational Research, 2013
Model risk has a huge impact on any risk measurement procedure and its quantification is therefore a crucial step. In this paper, we introduce three quantitative measures of model risk when choosing a particular reference model within a given class: the ...

Model Risk of Risk Models [PDF]

open access: yesSSRN Electronic Journal, 2014
This paper evaluates the model risk of models used for forecasting systemic and market risk. Model risk, which is the potential for different models to provide inconsistent outcomes, is shown to be increasing with and caused by market uncertainty. During calm periods, the underlying risk forecast models produce similar risk readings, hence, model risk ...

Risk prediction models [PDF]

open access: yesNephrology Dialysis Transplantation, 2013
Prognostic research focuses on the prediction of the future course of a given disease in probability terms. Prognostication is performed by clinical decision makers by using risk prediction models that allow us to estimate the probability that a specific event occurs in a given patient over a predefined time period conditional on prognostic factors ...

Model Risk and Basic Approaches to its Estimation on Example of Market Risk Models [PDF]

open access: yesФинансовый журнал, 2022
Model risk is currently a topic of great interest both to the academic community and to the financial industry; however, there is not yet any generally accepted approach to measuring it as of now.

Modelling environmental risk [PDF]

open access: yesEnvironmental Modelling & Software, 2005
As environmental issues have become increasingly important in economic research and policy for sustainable development, firms in the private sector have introduced environmental and social issues in conducting their business activities. Such behaviour is tracked by the Dow Jones Sustainable Indexes (DJSI) through financial market indexes that are ...

Quantifying the Model Risk Inherent in the Calibration and Recalibration of Option Pricing Models

open access: yesRisks, 2021
We focus on two particular aspects of model risk: the inability of a chosen model to fit observed market prices at a given point in time (calibration error) and the model risk due to the recalibration of model parameters (in contradiction to the model ...

Omega risk model with tax [PDF]

open access: yes, 2014
In this paper we study the Omega risk model with surplus-dependent tax payments in a time-homogeneous diffusion setting. The new model incorporates practical features from both the Omega risk model(Albrecher and Gerber and Shiu (2011)) and the risk model

Model risk in credit risk

open access: yesMathematical Finance, 2019
AbstractWe provide sharp analytical upper and lower bounds for value‐at‐risk (VaR) and sharp bounds for expected shortfall (ES) of portfolios of any dimension subject to default risk. To do so, the main methodological contribution of the paper consists in analytically finding the convex hull generators for the class of exchangeable Bernoulli variables ...

Validation of corporate probability of default models considering alternative use cases and the quantification of model risk

open access: yesData Science in Finance and Economics, 2022
In this study we consider the construction of through-the-cycle ("TTC") probability-of-default ("PD") models designed for credit underwriting uses and point-in-time ("PIT") PD models suitable for early warning uses, considering which validation elements ...
