  • Investment Commonality across Insurance Companies: Fire Sale Risk and Corporate Yield Spreads

  • Insurance companies often follow highly correlated investment strategies. As major investors in corporate bonds, their investment commonalities subject investors to fire sale risk when regulatory restrictions prompt widespread divestment of a bond following a rating downgrade. Reflective of fire sale risk, the clustering of insurance companies in a bond has significant explanatory power for yield spreads, controlling for liquidity, credit risk, and other factors. The effect of insurer clustering on bond yield spreads is more evident for bonds held to a greater extent by capital-constrained insurance companies, those with ratings closer to National Association of Insurance Commissioners risk categories with larger capital requirements, and during the financial crisis.

  • Summary

    An important aspect of the “black box” of schooling is the student and the cultural, economic, and social capital the student brings into the classroom. This chapter reviews the conceptual and historical development of various aspects of student background and how these have been included in international comparative studies. Also identified are three major rationales for including student background in any study of student achievement and the methodological and conceptual consequences of ignoring it.

  • Summary

    This chapter explores some methodological and conceptual issues that affect the extent to which any large-scale or international comparative assessment may inform education policy and practice. Insights are drawn from the studies reviewed in previous chapters. Some of the issues discussed include the ubiquitous cross-section design and the imperative necessity of identifying the source of student performance variation in order to appropriately inform education policy.

    Managing Security Information

  • Summary

    South Africa's mineral wealth is known around the world, as is the diversity and richness of its cultures and the attraction of its major landmarks, including cities such as Cape Town and Johannesburg, both of which featured as ‘major cities with the highest quality of life in the world’ during a recent survey. These are some of the many drivers that attract over 10 million visitors to the shores annually.

    Unfortunately, some see another side to life, and death, in South Africa, in terms of its crime rate – notably including over 50 murders a day according to the most recent crime statistics. This alone presents a mammoth task for the countries public and private security practitioners to identify, analyse and evaluate such rich data, or ‘big data’ as it is now known, to enable them to make meaningful interventions to protect life and property.

    In this book, Professor Govender has identified the need for effective security information management, with the emphasis on the term information, as opposed to the often-misused term intelligence. Google Dictionary differentiates the two terms as: “Information – facts provided or learned about something or someone” and “Intelligence – the collection of information of military or political value.” It goes without saying that information is considered the core ingredient of intelligence and so requires effective management and processing to be of real value.

    Bringing attention to the need for a structured approach to information management, as an essential tool in the kitbag of all security professionals, Professor Govender's model is something to be applauded and highly recommended throughout both private and public sectors. If applied consistently and effectively, this must ultimately lead to an improvement in information-sharing between stakeholders and intelligence-led interventions to reduce incidents of crime and the effects of them.

    The security information management model (SIMM) developed is based upon his extensive personal experience as a senior police officer in South Africa and leading academic with research across the globe. This research was most notably in South Africa and Australia, but has significant references to other models such as the USA's Compstat and UK's intelligence-led approach to policing and the National Intelligence Model (NIM), essentially information management systems that I am more familiar with as a retired London detective!

    Having relocated to South Africa and moved into the private security sector, I have all too often heard people rave about a practice in such and such a country that they have tried to implement locally, only to see it fail to produce the expected results.
