Presentation prepared for the V Congreso Economia de la Salud de America Latina y el Caribe November 15-16, 2012, Montevideo, Uruguay
Key Policy Paradigm
¨ Choice
¨ Choice of what?
· Providers – provide services
· Health plans – pay providers
· Sponsors – collect from consumers, pay health
plans
¨ Choice + heterogeneity Incentive to select
¨ Regulations + payment policy reduce
selection
Competition?
Four questions examined for Canada, Chile, Colombia and United States¨ How are payments and contracting arranged in the health
care system?
¨ What choices are allowed?
¨ What are the perceived selection problems?
· Efficiency problems
· Equity/fairness problems
¨ What selection tools are used that worsen or reduce
selection?
¨ Goal is to understand how to better use of risk adjustment,
risk sharing, and regulations

Key findings from comparisons¨ Countries vary in the choices, problems, and selection tools
available
¨ Objectives vary: Canada values income and risk solidarity
much more than US; Chile and Colombia are in between
¨ Service selection problems arise where there is a selective
contracting or pricing with providers (US, Chile, Colombia)
¨ Sponsorship by employers leads to more selection problems
than sponsorship by a government entity
¨ Risk adjustment and risk sharing are relevant at many
different levels of the health care system.
¨ Regulations are as important as financial incentives.
¨ Paper says nothing about cost and quality efficiency.
