Employer-Sponsored Health InsuranceIn 2006, approximately 90% of privately- insured, nonelderly Americans received coverage through an employer-sponsored plan

2010: Patient Protection and Affordable Care Act “Obamacare” Beginning in 2014, prohibits pre-existing condition

exclusions in which will eliminate the individual and small-employer group market

Employers with >50 employees will have to offer health insurance or pay a fine

Most employers will pay the fine and drop coverage

3

Why Employer-Sponsored Health Care?

• Favorable tax treatment– Premiums deducted as a business

expense (pre-tax dollars!)• Economies of Scale in the purchase and

administration of group policies

4

The Big Question:

• Why is there virtually no market for individual insurance policies?– Contrast with the vibrant individual market

for life insurance which co-exists with the employer-sponsored life insurance benefit

– In 2003, for example, only ¼ of the 20% of Americans without access to an employer plan or public insurance were covered by an individual policy

5

The “Answers”:• The tax subsidy mentioned above• Low demand caused by myopic behavior

by young adults• Crowding out of the private market by

public insurance programs– Medicaid– SCHIP

• The topic of today’s discussion....

Classification Risk

All Consumers are Healthy

Consumers Purchase

Insurance at the “healthy” premium;Some claims paid

Over Time, Some Stay Healthy

While Others Develop“chronic” conditions

Depart the RiskPool to be Re-Underwritten

Stay in the Pool and Pay High

Premiums

“ClassificationRisk”

8

How Do We Keep the Healthy Individuals in the Risk Pool?

• Have consumers sign long-term contracts to remain with the insurer– Historically, non-enforceable

• Charge front-loaded premiums, as in whole life insurance– This is a lot more difficulty in health care

where future technologies and costs are uncertain

9

A Third Solution….

• Tie Health Insurance to Employment• If it is costly for employees to switch

jobs, then it is difficult to move to another employer for a better health insurance deal

• The Key Insight: Job market frictions create job attachment which translates into more stable insurance pools.

10

Job Attachment and Stable Insurance Pools

• The ability of the healthy to depart and be medically re-underwritten is constrained by their Job Attachment

• Healthy workers find it less onerous to be pooled with the unhealthy when there are coverage restrictions

• The Hypothesis: There should be a positive relationship between job attachment and the generosity of the health care plan

11

The Data

• 1987 National Medical Expenditure Survey (“NMES”)– Lifetime limits on benefits– Annual Stop-Loss

• 1977 Dictionary of Occupational Titles– “Specific Vocational Preparation (SVP)”– A measure of specialized job skills

12

Specific Vocational Preparation“The amount of time required to learn the techniques, acquire

information and develop the facility needed for average performance in a specific job-worker situation”

Conclusions

• There is a clear and strong relationship between the stability of the pool, as measured by job attachment, and the ability of insurers to offer more generous healthcare coverage

• Proposals to supplant employee group plans with individual market alternatives should be viewed with caution
