ECON 440 Lecture Notes - Lecture 17: Essential Health Benefits, Risk Pool, Adverse Selection

49 views5 pages
Strategies we can use to reduce adverse selection tend to reduce competition and choices,
and vice versa
Competition (Choice) vs Adverse Selection
Individuals may be in the "wrong" plan
Limited risk pooling
Missing market for generous coverage
Three social welfare losses
e.g. the ESI setting: they offer multiple plans, range of generosity, premium costs, etc.
Citizens often have a choice of insurance plans
In the US, emphasis is put on the value of choice (partly political, partly cultural decision)
Second Fundamental Tradeoff in Health Economics
e.g., essential health benefits
Standardizing plans
Mandated benefits
In the limit, single insurance plan (no choice, no competition)
Regulation
Employers or government can try to keep middle-types in the more generous plan by
subsidizing the premium for people
This is so that when premiums start to diverge, subsidies can keep the risk pool more
balanced between these options
Subsidize premium for more generous plan
Have to be able to identify who is healthy and who is sick ex ante
Difficult to do in practice, especially for the highest-cost patients in a given year
But, the financial compensation may incentivize insurers not to avoid less-healthy
people (limiting strategic avoidance/behavior)
Risk adjustment: pay insurers more for sicker patients (ex-ante or ex-post) for having ended
up with a sicker than average risk pool
Payment
There's money put aside to compensate insurers who cover the highest-cost patients
In the extreme, highest E(costs) patients could be insured separately by a different
entity
Highest-cost patients are paid for out of a separate fund (essentially ex post risk adjustment)
Reinsurance
Strategies to Avoid Adverse Selection
What impact would the merger have on market share; competition?
Checking whether certain mergers should be allowed or not
Anti-trust
Medicare Advantage and Part D
Medicaid
Within public programs: (legislation mandates that choice be made available)
Exchanges are structured to provide individuals with more choice - choices are laid out
in a way to facilitate comparison
Health Insurance Exchanges
Range of generosity, premium costs, etc.
Employers offer multiple plans
Choice of private HI plans
Consumer-driven health plans (consumer-centric)
Innovations in insurance coverage
Strategies to Promote Choice and Competition in Insurance

Facing higher OOP costs will make the consumer make better choices about the care
they consume
Reduction of MH consumption
Consumer-driven health plans (consumer-centric)
Puts emphasis on covering more valuable services more generously
Value-based insurance
Cost reflects the value of the healthcare service
Variable cost-sharing
The physician has information, and can make decisions about which care is best
Managed care
Variation in what a health insurance plan looks like given people more choice and creates
opportunities for selection to occur…
If we left the market unregulated, plans will be more profitable as they avoid the sickest
enrollees
Strategy to increase efficiency (maximum value for money) in health insurance markets
Rewards plans that do the best job of improving quality, cutting costs, and satisfying
patients with more enrollees and more revenue
What we want to do is reward the plans that provide better quality insurance at a lower price
with more enrollees
How can we have competition, and manage it in a way that the market works better than an
unregulated market?
What effect does competition in the private market have?
i.e., competition forces them to respond adequately to purchaser demands
Divide insurers in each community into competing economic units and use market forces to
motivate them to develop efficient delivery systems
Government (Medicare), employers
Health Insurance Purchasing Cooperatives (Clinton)
Commonwealth Choice (MA)
Health Insurance Exchanges (Obama)
Switzerland, the Netherlands
Sponsor above plans, above providers
Relies on a "sponsor" to structure, monitor, and adjust the market for competing health plans
In a structured way, the sponsor is trying to get insurers to compete with each other
Managed Competition (provider-centric)
Community-rated premia: probability of a loss and risk of loss is calculated from the risk
pool
e.g. having some middle-ground where the premium for the highest risk people can
only be 2x as high as the premium for low risk people (similar to ACA)
Continuous coverage, community-rate premia, no exclusions based on pre-existing conditions
e.g. pricing, tax-credits
Individuals have subsidized access to the cheapest plan
Establish market rules and regulations to ensure access to all/nearly all people who would like to
buy insurance
e.g. the ACA bases its premium subsidies on bronze (low) and silver (moderate) quality
plans - if the individuals want more generous plans, they're responsible for the
difference in pay (i.e. they pay the MC of the decision)
Consumers are responsible for any price difference if they choose more expensive plans
Enables people to make informed decisions so they can respond accurately to
price/quality elasticity
Plans are standardized and information publicized to facilitate comparisons on price and
quality
High-powered incentives: $1 saved means $1 to the individual
Create price-elastic demand
