Description: This paper argues that no single valuation basis is completely reliable: neither market price nor other alternatives can accurately measure value. Therefore, this paper proposes that a preferable solution is to simultaneously record two bases of valuation: market price and appraisal value. Thus by expanding the dimensionality of financial reporting, one can provide a broader, richer and more accurate measurement of value. Presented at 2010 Enterprise Risk Management Symposium, Society of Actuaries, April 12-15, 2010

Description: There have been continual advances in the modeling of financial series but most are aimed at the pricing of derivatives. Different criteria are needed for development of scenarios for risk management. Some recent methods will be reviewed with an eye on risk-management applications, including using the simulated method of moments to parameterize multifactor models, fractional differencing and other methods to model series with persistent autocorrelation, and models to flatten out the volatility smile, such as jump-diffusion models. These methods will be illustrated with applications to inflation, interest rates, equity prices and exchange rates.
