Description: In this paper, the authors take an axiomatic approach to characterize insurance prices in a competitive market setting. Four axioms are presented to describe the behavior of market insurance prices. From these axioms it follows that the price of an insurance risk has a Choquet integral representation with respect to a distorted probability.

Description: Presented at May 2005 Spring Meeting. This session examines financial, economic and traditional actuarial methodological approaches used for solving investment-risk problems.

Description: This abstract describes a paper that investigates the effect of ambiguity on the market for insurance when preferences are ordered by comparison of Choquet expected utilities.

Description: This article discusses equity risk premium, what it is, how it should be measured, if a constant risk premium provides the best model and what are reasonable expectations for the future.

Description: Many retirement actuaries have experience developing, implementing, and monitoring Liability Driven Investing (LDI) strategies for plan sponsors. These strategies typically involve modifying a plan’s investment strategy to remove a significant portion of the investment and interest rate risk now or at some point in the future when specific triggers are met. The tactics often involve the use of fixed income assets to cash flow and/or duration match the liabilities. In the spirit of helping actuaries expand their roles in an evolving defined contribution world, this article explores the application of LDI and derisking strategies within defined contribution and individual retirement accounts. The economic theory behind this approach is called the lifecycle hypothesis, or lifecycle finance. The benefits of the lifecycle finance method are that it provides a safe approach to save for retirement and a secure source of floor income during retirement. Similar to pension plans, each individual has his or her own idiosyncratic needs, wants, and risks that should be considered. Actuaries are uniquely situated to help defined contribution plan sponsors, individuals, and even themselves implement the lifecycle finance approach by developing and distributing tools and methods that focus on income (rather than wealth), LDI strategies, and personalization.

Description: This article addresses the difficulties of risk modeling in a poor economic environment. The problems include imperfect vendors of data, facing events that have never occurred before, unpredictable consumer behavior, conflicting data sources, and AAA credit doesn't always mean AAA.

Description: This abstract describes a paper that improves upon current multivariate statistical models for predicting the pre-payment rate of reverse mortgages, which are heavily data-driven. The prosposed model extends a semi-Markovian joint-life mortality model to incorporate three main termination modes of reverse mortgages: death, long-term care LTC entry, and non-health related termination.

Description: This session reviews the past half century's advances in finance such as immunization and hedging theory, modern portfolio theory, capital asset pricing model, option-pricing theory, term structure of interest rate models, and so on. Their application to asset and liability management in insurance and pensions is highlighted and discussed.
