Our society is fascinated with risk in many different areas and disciplines. One of the main ways to describe and communicate the level of risk is through risk indices, which summarize risk using numbers or categories such as words, letters, or colors. These indices are used to communicate risks to the public, understand how risk is changing over time, compare among different risks, and support decision making. Given the different methods to construct risk indices, including flawed methods such as risk matrices, this article develops specific steps that analysts can follow to create a risk index. This article emphasizes the importance of describing risk with a probability distribution, developing a numerical risk measure that summarizes the probability distribution, and finally translating the risk measure to an index. Measuring the risk is the most difficult part and requires the analyst to summarize a probability distribution into one or possibly a few numbers. The risk measure can then be transformed to a numerical or categorical index. I apply the method outlined in this article to construct a risk index that compares the risk of fatalities in aviation and highway transportation.

GARP's Foundations of Financial Risk creates a comprehensive understanding of financial risk and the regulatory environment under which institutions operate. It focuses on core financial risks: market, credit, and operational--and how international regulation, including the Basel Accords, affect the management of these risks. (Back cover)

Any practical process of risk ranking must group hazards into a manageable number of categories. Defining such categories requires value choices that can have important implications for the rankings that result. Most risk‐management organizations will find it useful to begin defining categories in terms of environmental loadings or initiating events. However, the resulting categories typically need to be modified in light of other considerations. Risk‐ranking projects can benefit from considering several alternative categorization strategies and drawing upon elements of each in developing their final categorization of risks. In principle, conducting multiple ranking exercises by using different categorizations could be interesting and useful. In practice, agencies are unlikely to have either the resources or patience to do this, but other groups in society might. Done well, such additional independent rankings could add valuable inputs to democratic risk‐management decision making.

This product is not available separately, it is only sold as part of a set. There are 750 products in the set and these are all sold as one entity, Risk assessment is considered by many analysts to be an objective scientific tool. It is considered to be variously influenced by broader issues which in turn have important practical implications both for risk assessors and decision makers. Risk Assessment and Risk Management examines a range of practical applications of risk assessment methods and risk management procedures in the broad context of environmental science and technology. Written by acknowledged experts in the field, the articles cover a variety of areas, with reference to subjects as diverse as BSE, the use of risk assessment in government, using computer modelling as an aid to risk assessment in the case of accidental contamination of rivers and estuaries, quantitative cancer risk assessment related to carcinogens in the environment, landfilling of household wastes, environmental risk assessment and management of chemicals, and aquatic risk assessment and management of pesticides. This book provides a detailed and wide-ranging review of the many aspects of risk assessment and risk management which have excited so much debate and controversy in recent times. It will be essential reading for all those involved in the assessment and management of risk, particularly in the context of environmental science

Systemische Risiken sind das Produkt tiefgreifender und rasanter technologischer, ökonomischer und sozialer Veränderungen, welche die moderne Welt jeden Tag erlebt. Sie sind durch hohe Komplexität, Ungewissheit, Ambiguität und sich allmählich ausbreitende Wirkungen charakterisiert. Aufgrund dieser Eigenschaften überfordern systemische Risiken das etablierte Risikomanagement and erzeugen neue ungelőste Herausforderungen für die Politikgestaltung in der Risikosteuerung. Ihre negativen Auswirkungen sind häufig durchdringend und beeinträchtigen Bereiche jenseits der direkt ersichtlichen Schadensbereiche. Der Artikel bezieht sich auf ein integratives Risikokonzept zur Bewältigung systemischer Risiken, das Bewertungskriterien, unterschiedliche Risikoklassen und entsprechende Managementstrategien berücksichtigt. Wir argumentieren, dass es eines deliberativen Ansatzes im Risikomanagement und in der Politikgestaltung in der Risikosteuerung bedarf, um systemische Risiken vermeiden, mildern oder kontrollieren zu können.
