Robust risk measurement and model risk

Quantitative Finance, 2012
Financial risk measurement relies on models of prices and other market variables, but models inevitably rely on imperfect assumptions and estimates, creating model risk. Moreover, optimization decisions, such as portfolio selection, amplify the effect of model error. In this work, we develop a framework for quantifying the impact of model error and for

Abstract Governments in developing countries invest large amounts in public infrastructures. However, information on economic risk on the project level is hardly ever included in the assessment of a project’s feasibility. Practitioners normally restrict their analysis to one factor at a time sensitivity analysis, which is insufficient information to ...

IMPRECISE PREVISIONS FOR RISK MEASUREMENT

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2003
In this paper the theory of coherent imprecise previsions is applied to risk measurement. We introduce the notion of coherent risk measure defined on an arbitrary set of risks, showing that it can be considered a special case of coherent upper prevision.

How to Measure Risk?

1999
In financial optimization, the future distribution of wealth is projected by methods of statistical estimation and simulation. For making decisions, different wealth distributions have to be compared and the optimal has to be chosen. In this paper we discuss methods of assigning measures for risk (which are to be minimized) and measures for safety ...

The measurement of investment risk

Journal of the Institute of Actuaries, 1987
1.1 In the paper ‘Improving the Performance of Equity Portfolios’ by Clarkson and Plymen the authors concluded that Modern Portfolio Theory methods made no contribution whatever to improving the performance of equity portfolios and suggested that attention should be paid instead to the application of fundamental analysis, which—if carried out by ...

Risk Measures: Value at Risk and beyond

2013
In the late 90s an increasing interest has been developing towards risk measures, in particular the Value at Risk (VaR) and the Conditional Value at Risk (CVaR). The use of such risk measures is due, on the one hand, to the rules imposed by the Basel Accord on the deposit of margins by banks and financial institutions because of the financial risks ...
