Why is employer sponsored health insurance so popular?

•Should ask: Why do (some) workers prefer to pay for ESI with reduced wages?

 

•Answer: ESI is a much better deal than individually-purchased coverage.  There are three main reasons:

1.Efficient risk-pooling

2.Economies of scale in marketing and administration

3. Substantial tax subsidy

 

Advantages of ESI are the mirror image of the limitations of the existing individual market.

Employer Sponsored Health Insurance

Employer Health Insurance and the Labor Market

The link between health insurance and the workplace (and the lack of other affordable options) can distort worker behavior. The result is various types of “job-lock”:

• Job mobility
• Entrepreneurship
• Weekly hours
• Retirement

Broader labor market trends contributed to reduced access to ESI:

• Declining labor force participation
• Dislocation from technology and trade
• Declining unionization
• The “gig economy”

Health Insurance by Income Level

Poverty Line Cheat Sheet

ACA Expanded Coverage in 3 Ways

1.Young adults allowed to stay on their parents’ private insurance until age 26 (effective September 2010)

 

2.Eligibility for Medicaid extended to everyone with incomes below 138% of the Federal Poverty Level (effective Jan 2014*)

 

3.New tax credits for private insurance for families between 100 and 400% of the Federal Poverty Level (effective Jan 2014)

 

* Several states elected to expand Medicaid at different times, or not at all!

Medicaid Expansion

Medicaid Expansion

How does the government plan to expand Medicaid?

• Federal match assistance percentage (FMAP): States were historically guaranteed at least a 1-to-1 match from federal government.
  • Higher match rate for lower income states (highest is MS, 2.8 to 1 in 2015)
• Under ACA, federal government pays 100% of additional costs during 2014-2016, then phases down to 90% by 2020.
• Under the original law, states have to expand Medicaid or risk losing all of their funding

NFIB v Sibelius 2012

High profile supreme court case challenging constitutionality of the ACA:

 

SCOTUS ruled the threat of losing all Medicaid funding was unconstitutionally coercive, a "gun to the head" as Roberts wrote in his majority opinion.

 

Because of this ruling, states could opt not to expand Medicaid without risking losing additional funding.

 

Also gave states some negotiating power to expand on their terms. 

Opted to Expand in 2014

As of 2015...

As of 2017...

As of today...

Can States Afford to Expand?

Medicaid is the single largest item in most state budgets.

• 10% of a big number is a big number
•  Is expansion is a financial burden on states?

• In many states Medicaid reduces the need for other state-funded programs.
  • In Michigan: expansion must be budget neutral or it will be automatically ended in 2017.

•UM analysis: Michigan actually saved money on its expansion by cutting other programs that were now provided by Medicaid (e.g. health care programs for recent inmates, low income parents, and special mental health programs).

(Ayanian et al. New England Journal of Medicine 2017)

Private Coverage Provisions

Underwriting reforms:

• "Guaranteed issue": no denials or exclusions for pre-existing conditions

•Adjusted community rating: premiums vary by age, smoking status, but nothing else

-Results in higher premiums for those who are younger, men; lower premiums for older, women

Adverse Selection

Recall our Adverse Selection example from last time:

Imagine there are two groups of people: the sick and the healthy.
Sick have a 5% chance of a $100,000 health bill.
The healthy have a 1% chance of a $100,000 health bill.
 
Say the insurance company starts out with 50% sick and 50% healthy.
What do we think might happen, when the sick and healthy select into plans?

Private Coverage Provisions

Individual mandate

Tax penalty for not having insurance (now repealed)

• 2014: max[$95 per adult, 1% of income]
• 2017: max[$695 per adult, 2.5% of income]
• 2018 forward: $0

Premium Tax Credits

•Available between 100% and 400% of poverty

•Eligibility limited to people without access to affordable ESI

•Can only be used for coverage in newly established “marketplaces”

Health Insurance "Marketplaces"

The goal: make it easier to shop for health insurance if you don't have coverage through an employer 

•Consumers choose from a menu of private plans

•All plans must offer 10 “essential health benefits” and conform to one of four actuarial value “metal levels.”

•Tax credits are based on consumer income and the premium for the 2nd lowest cost silver plan.

• 100-133 % of FPL: premiums are capped at 2% of income
• 300-400% of FPL: premiums are capped at 9.7% of income

•Low-income enrollees also qualify for cost-sharing reductions.

States: How are they preventing death spirals, reducing adverse selection or improving moral hazard?

Health Insurance Marketplaces

Note: if a consumer gets a subsidy, then what the consumer actually pays doesn't actually depend on the price--it depends on the consumer's income.

 

When prices go up, the consumer doesn't necessarily pay more... (who does?)

Rise of Narrow Network Plans

•Ultra narrow plans contract with < 30% of hospitals in the market

•Narrow plans contract 30% to 70% of hospitals in the market

•Broad plans contract with > 70% of hospitals in the market

Marketplace Enrollments

Withdrawal of "household name" insurers:

 

Exits 31 states in 2016/2017; remains partially active in New York, Nevada, and Virginia.

Withdraws entirely (from 13 states) in 2017/2018 transition.

Exits entirely (11 states) in 2017/2018 transition

Marketplace Enrollments

Success of plans with Medicaid managed care experience:

Narrow networks (e.g. So Cal plans exclude UCLA)

600k enrollees

Profitable

1.2 million marketplace enrollees

Low premium, high deductible, narrow network

Dependent Coverage

Dependents can remain on parents' coverage until age 26

• One of the most popular aspects of the bill

Employer Mandate (50+ FTEs)

•Penalties only apply if 1 or more full-time employee receives a premium tax credit in the exchange. 

•Penalties do not apply to first 30 employees

•B penalty is capped at the amount of the A penalty (i.e., $2K/employee)

Costs employees less than 10% of their income? ("Affordable")

(And at least 1 employee used the  tax credit)

Evidence on Coverage Gains

About ~2 million gain coverage

through dependent mandate

Overall Coverage Gains (Non-elderly adults)

The number of people with insurance increased by 20 million between 2010 and 2015

Significant Premium Volatility

Which price is relevant...?

Recall--the listed premium isn't relevant for 85% of enrollees who are receiving subsidies (capped as % of income).

• For these consumers, net of subsidy premium has declined.

 

Risk Selection in Marketplaces

•More evidence of adverse selection in non-expansion states (Peng 2017), especially “direct enforcement” states that most strongly resisted the ACA (Kowalski 2016) and states that permitted non-compliant plans to continue to be sold (Lucia and Corlette 2017).

 

Stabilizing effect of the tax credits--reduces death spiral tendencies.

 

But for "higher end" products (Platinum plans) death spiral appears to have happened.

Competition on the Exchanges

About 20% of enrollees have only one insurance company offering plans--far from the "perfect competition" ideal

This is worse in rural locations

Premiums are lower and more stable in markets with robust competition

Effect of the ACA on patients and providers

Medicaid Expansions

• Take advantage of non-universal adoption of the Medicaid expansion that resulted from the 2012 Supreme Court decision.
• Use a "difference in differences" quasi-experimental empirical design

Difference in Differences

Let's go back to this figure:

One way to represent this would be to subtract out the difference in one year (normalize to zero) and then plot the remaining difference. 

Difference in Differences

Uninsured

For low income adults--probability of being uninsured went up in expansion states
(Miller and Wherry 2019 AEA P&P)

On Medicaid

For low income adults--probability of being on Medicaid went up in expansion states

Privately Insured

For low income adults--probability of being privately insured went down in expansion states

Needed Care but Couldn't Afford it

Needed Specialty Care but Couldn't Afford it

Delayed Care due to Affordability

Problems Paying Bills

Mortality Effects

Reduction in mortality of about one tenth of a percentage point (about 9.4%). Implies 19,200 fewer deaths from 2014-2017 in expansion states (or ~15k excessive deaths in non-expansion states)

Effect on Providers

Because hospitals must accept all patients regardless of ability to pay, they are “insurers of last resort.”

• Each uninsured person generates an average of $900 in uncompensated care per year.
• 2013: hospitals provided ~$45 billion in uncompensated care

  (~6% of expenditures)

 

Hospitals were advocates for reform and for continued Medicaid expansion.

Labor Market Effects of the ACA

Potential Labor Market Effects

•The CBO projected that the ACA would reduce labor supply by roughly 2%. The largest effect was on retirement.

•Effects on labor supply could represent an improvement in labor market efficiency as job-lock is eased.

•Effects on labor demand may be inefficient if employers are distorting hiring to avoid cost of coverage (especially employers with 50 FTE+ who might get hit with a penalty).

 

So far, there is little evidence of effects on either supply or demand--this was a surprise to most economists.

Nothing going on with early retirement...

(Levy et al 2017)

Length of unemployment spells... no obvious effect

Change to the ACA under the Trump Administration

Continued growth in Medicaid coverage

• During the Trump administration, 6 states (VA, ID, LA, NE, UT and ME) elected to expand Medicaid.
• Federal government has been much more permissive in issuing waivers, giving states more flexibility:
  • Work requirements for Medicaid--but these have been struck down by the courts
  • Allow "short term" health plans that don't follow ACA regulations

Make Obamacare Great Again

Ironically, more people seem to like the Affordable Care Act after President Trump's election...

Mandate Repeal

To reduce adverse selection, the ACA included an individual mandate to purchase insurance with a penalty if you did not purchase it. This was repealed for tax year 2017.

Appears to not have had that big of an effect:

• Relatively few tax filers paid the penalty: about 12m were "exempted," 6.7 paid penalty
• Some confusion about whether mandate was repealed (about 40% did not know in latest Gallup poll)
• Many enrollees are subsidized, which is larger than the penalty

Short-term plans

A "loop hole" to allow insurance companies to not cover pre-existing conditions or all essential health benefits (e.g., maternity coverage) is to let them offer "short term" plans which are exempt from this regulation.

• Only permitted to cover for 3 months under Obama admin; Trump admin allows them to cover 364 days, renewable 3 years.
• Much cheaper than exchange plans--about 1/3 the cost--but cover less and don't cover pre-existing conditions.
• There is a concern they will pulling healthy people off of the exchanges, setting off a "death spiral."

Coverage

Biden Adminstration

A variety of COVID-related policy made it difficult to untangle what exactly is driving changes in coverage--but higher insurance rate coverage ever reported was in 2022.

• COVID relief bill temporarily eliminated "jump" in premiums that occur once you hit the income cutoff 
• Public health emergency meant no kicking people off of health plans, government subsidized coverage for recently uninsured
• Some extensions in Medicaid coverage (e.g. expand coverage beyond 60 days post partum for new mothers)

Proposed solutions?

"Reinsurance"--encourage more insurance companies to offer exchange plans by having the government step in and cover the costs for patients who end up being particularly expensive.

 

AK, ME, MN, NJ, OR and WI all have applied to start such a program.

Government covers some fraction (e.g., 80%) of claims above some threshold (e.g., $50k)

 

Not cheap--Alaska has spent $55million on only 17k individuals, and expected costs to scale nationally are estimated to be about $38 billion.

 

Proposed solutions?

"Public option"/Medicare Buy-In:

 

Allow enrollees to "buy in" to Medicare at premiums that cover cost.

Medicare pays about 60% of what employer-sponsored insurance pays.

Forces plans to compete with Medicare

• on the plus side, lowers premiums (7-8% according to CBO in 2013)
• on the negative side, may drive some plans from the market and decrease choice.

Proposed solutions?

"Public" Medicare-for-All

Eliminate private insurance and replace it with Medicare.

• Everyone gets covered.
• People like Medicare when they get it.
• Market based solutions (ACA) haven't been as popular as drafters hoped.
• Private insurance is expensive, we could reduce costs by switching to public plan.
• Eliminates choice, less innovative
• Disruptive, providers won't be happy

Proposed solutions?

"Private" Medicare-for-All

Eliminate individual or employer sponsored private insurance and replace it with regulated private plans paid for by the government.

• Could cover everyone.
• Greater choice than "Public" Medicare for all (although potentially still less choice than current system).

Proposed solutions?

Market based approaches:

• Roll back regulations from ACA and allow market to provide greater range of products.
• Roll back Medicaid expansion and focus Medicaid coverage on the very needy or those with high health needs: pregnant women, poor children, disabled, elderly in nursing homes.
• Fewer people might choose to get covered, but those who got covered would have more options--"skimpier" but cheaper plans available might induce some currently uninsured to buy in.
• Pursue other (non-coverage related) policies like tort reform, reducing regulations and restrictions that could potentially lower costs.
• Reduce preferential tax treatment of ESI and replace it with advanceable/refundable credit

Proposed solutions?

Market based approaches:

• Improve price transparency
  • CMS issued rule that hospital prices for 300 "shoppable services" must be posted
  • This would include what price each insurance company pays 
  • AHA sued, saying these negotiated rates were confidential
  • Judge ruled against AHA--Prices were required to be posted Jan 1, 2021, but many hospitals have not complied

State question:

Did your state expand Medicaid under the ACA?
