Risk‐Based Capital Allocation Using a Coherent Measure of Risk
This article outlines a procedure for quantifying risk‐adjusted capital reserves that may be used for both performance evaluation and capital allocation. The author identifies and quantifies the sources of risk capital that must be addressed, to cover current investment and withstand market shocks, for any business line that exhibits earnings volatility. The author classifies risk capital into two types: market‐risk capital and earnings volatility‐related capital. Market risk capital may be divided into two categories; risks due to “normal” or “diffusion” type price movements and catastrophic moves or “stress” events. In contrast, earnings volatility‐related capital is directly related to the firm's equity‐at‐risk, in the event that market shocks lead to sustained earnings volatility. The author suggests that these risk‐adjusted capital measures may be used as a benchmark, in conjunction with net earnings, to evaluate performance, or to allocate equity capital across different operations within a firm.
Natural Catastrophe Probable Maximum Loss
ABSTRACT The procedure for estimating probable maximum loss (PML) for natural catastrophes has evolved over the past few decades from a rather simplistic deterministic basis to a more sophisticated methodology based on loss exceedance probability curves, generated using catastrophe modelling software. This development process is reviewed, with an emphasis on the earthquake peril, which, because of its widespread threat to critical industrial installations, has been at the forefront of most PML advances. The coherent risk definition of PML is advocated as an improvement over standard quantile methods, which can give rise to anomalous aggregation results failing to satisfy the fundamental axiom of subadditivity, and so discouraging the pooling of risks.
Development of Science and Technology in the Iranian Electric Power Industry: Challenges and Future Progress
This chapter examines four key segments of the electric power industry in Iran: generation, transportation, distribution and consumption. It reviews the method, development, and evolution of electric power generation in the country. Specifically, the chapter reviews the structure of the electric industry, the main players, institutions, standards as well as laws, human resources, technology, the export and import markets, and engineering management of the industry in the country. Finally, the challenges facing the industry will be identified and policy suggestions to remedy the problems will be provided.
