  4. Career Summary • 1987 BS Computer Science, Duke University, NC • 1987-1990 High School Teacher, Salzburg & NC • 1990-1991 Aetna Casualty, Hartford CT • 1991-1996 Fireman’s Fund, San Francisco • National Accounts • 1996-1998 Allianz International, Munich • International Casualty Underwriting • 1998-2000 Allianz Australia (MMI), Sydney • Chief Actuary; WorkersCompensation • 2000-nowPricewaterhouseCoopers, Sydney

  5. CAS Key Facts • Started in 1914 as a special interest group of the SOA • Generally covers USA and Canada • Initial Workers Compensation focus; now all “P&C” • Only separate society dedicated to GI business • Over 2,500 members • 10 Exams in 14 parts • Very little university training/preparation in US • www.casact.org

  6. CAS University Liaison Role • Information point for interested students • General promotion of GI Actuarial careers • Information on CAS research calls & commissions • Is there a place for the CAS in Australia? What can/should the CAS do to strengthen (establish!) its role here?

  7. Health Financing in Australia • Who funds healthcare? • Government—Commonwealth, State & Local (AHCAs) • Private Health Funds (PHI) • Accident Compensation Schemes (e.g. NSW WCA) • General Insurance Companies (for accident comp) • Individuals (patients!)

  8. Health Funding Overview (AIHW)

  9. Actuaries in health funding • New appointed actuary role—being developed by the HPC together with PHIAC • Pricing of member contributions (premiums); estimation of reserves, certification of financial position • Broader health arena—little involvement so far • What makes actuaries special? • Competition is health economists & epidemiologists • Connection to operational drivers • Projection of future values • Risk pooling / insurance concepts

  10. Basic economist’s modelling approach • Intergenerational Report 2002 (Australia): • Demand model, cost as output • Past commonwealth government health spending as % of GDP, trended forward (adjusted for age & gender). A simple high-level expenditure projection.

  11. Intergenerational Report 2002

  12. Intergenerational Report 2002 • IGR Points: • Technological change is main driver of growth (not demographics) • Government health spending (shown here) is growing faster than total health spending (more indicative of workforce trends)

  13. AHMC Workforce Modelling • PwC recently asked to develop a framework for a model of Australia’s health workforce • Want to analyse mismatch between supply & demand in the future • High-level concept only (so far)

  14. AHMC Workforce Modelling • (spreadsheet) • Flowchart of modelling approach • Public hospital admissions example

  15. Demand example: hospital services

  16. NSW WCA pricing analysis framework • Sequential pricing variance • How can we form a simple measure of the relative accuracy of various pricing approaches? • Basic concept is to minimise the variance of employer loss ratios under different pricing approaches • Another concept is to measure “within class” vs. “between class” variance • Both concepts will allow for objective evaluation and concise quantification of the relative performance of alternative options

  17. Sample analysis output (not real #’s!)

  18. NSW WorkCover Insurer Remuneration • Background: • NSW Work Comp has been a managed fund since 1988 • Large scheme deficit ($2.0b?) • Plans to privatise in 2000 have been delayed indefinitely • Current claims manager (insurer) remuneration system will expire June 2001 • WorkCover and insurance industry want to devise a new system which provides as much incentive as possible to manage to better claims outcomes

  19. “Loss Ratio measure” analysis framework • Pricing “fit” by insurer • Loss ratio measure may require a more “correct” pricing approach than the actual premium calculation system ever uses • We need to determine whether and to what extent any current insurer/agents are “out of the money” on the measure • The L/R measure may provide no real incentive to some insurers unless a more appropriate risk-based premium calculation is used • For example, an insurer may be significantly better than average in managing claims that arise, but that insurer’s employer portfolio could have a much higher than average claims frequency rate
