Separating Hyperplanes

Democrats have long supported the idea of adding a "buy-in" option to medicare and medicaid, where people who do not normally qualify for these programs could pay enroll anyway, provided that they pay their own way through premiums. The Clinton administration drafted several versions of a medicare buy-in, and Al Gore made it a plank in his presidential campaign platform in 2000. Democrats continued introducing bills on the topic throughout the Bush administration, and very nearly added it to the Affordable Care Act in 2009.

I think democrats have an unrealistic vision of how medicare buy-in would work in practice. They're confident the buy-in program would fund itself, that the insurance plan would be generous, and the premiums low. None of these things are true.

Urban institute analyzed the idea back in 2002 and had this to say:

Only a Medicare buy-in that provided subsidies to make the plan affordable to low-income people would significantly reduce uninsurance rates among the near elderly.

In fact, even when health insurance premiums are low, they are expensive. Americans spend almost as much on healthcare as on housing—our mental model for health insurance should be a major budget item closer in magnitude to paying rent than, say, car insurance. In practice, a Medicare buy-in program cannot be self-funding.

Further exacerbating this problem, Medicare would charge premiums much higher than most Democrats expect. Medicare spends an average of $10,000 per beneficiary per year on benefits, meaning an actuarially fair, community-rated premium for medicare would exceed $10,000 per year. Kaiser Foundation's calculator tells me that an unsubsidized plan for a 64 year old on the ACA exchanges would cost $10,160 per year, but at least with the ACA, there are subsidies for low-income folks.

Oh, and by the way, the ACA plan is better than that medicare plan. In fact, traditional medicare doesn't meet the ACA's minimum coverage requirements. I've written before about how medicare is actually crappy insurance that not only doesn't cap your out-of-pocket expenses, but actually increases them as your condition worsens.

A medicaid buy-in looks a bit better. Medicaid is great insurance that comes with very low out-of-pocket costs. Still, average medicaid spending per beneficiary is $6,502 per enrollee per year, still higher than what most folks pay for an ACA plan (though more generous). A big reason medicaid spending is higher than private insurance is that the enrollees are sicker. For one thing, seniors on medicare don't enroll in ACA plans, but many of them do enroll in medicaid. And think about it: if you had a catastrophic illness and couldn't afford care, you'd do whatever needs to be done to qualify for medicaid—quit your job, give away your assets, anything. Without hiring actuaries and risk-rating premiums, at least partially, to account for the fact that folks who opt into medicare or medicaid buy-ins would be lower cost than existing enrollees, neither plan looks very affordable.

That said, I think with one tweak to the medicaid rules could solve several problems at once: instead of charging a premium, charge a payroll tax.

The exact tax function should be empirically grounded, which is beyond the scope here, but here's a starting point to get the idea: your medicaid premium is equal to 0 percent of income up to federal poverty level, and 10 percent on income above that.

In principle, this buy-in option would exist for everyone, but in practice it would essentially phase out smoothly right around 400 percent of federal poverty level, as most folks above that level could find cheaper options on the ACA exchanges. That makes this plan comparable in scope to the ACA subsidies, except without the three separate cliffs that impose high effective marginal taxes on some folks under the status quo: medicaid eligibility cutoff at 133 percent of federal poverty level, the cost-sharing reduction cutoff at 250 percent, and the tax credit cutoff at 400 percent of federal poverty level.

My medicaid buy-in plan would reduce the disincentives to labor that we find under the current regime. The budgetary impact is ambiguous—although medicaid is more generous than ACA plans, pushing the effective subsidy size up, medicaid reimburses at significantly lower prices, pushing subsidy size down. However, the overall cost, including both on-budget and off-budget healthcare spending, is likely to be lower than the status quo as medicaid pays less and has lower administrative costs than private insurance. Recall also that ACA premiums—as well as the associated ACA subsidies—would also decline as sicker folks would tend to sort into medicaid rather than private insurance, making insurance more affordable for everyone, regardless of whether they use the buy-in option.

At the moment, there's no Republican plan to repeal and/or replace Obamacare. There are, however, a bunch of different options that various republicans and conservative think tanks have proposed. One might think that all of the options follow similar principles--like how Clinton's and Obama's health reform plans converged over the course of the 2008 primary. But the reality could not be more the opposite: republican proposals range from near-complete destruction of the individual market to massive expansion of entitlements.

Destruction of the individual market

I've been talking about this for a while, and the Urban institute has followed up with numbers: if republicans try to repeal the ACA through reconciliation alone, the result would not merely take us back to the pre-ACA market but actually destroy both the ACA and pre-ACA market. That's because community rating and guaranteed issue regulations can't be repealed through reconciliation, so without subsidies and without a mandate, there'd be considerably more adverse selection than we had before the ACA, with higher premiums and even fewer people covered than we had before the ACA.

Expansion of entitlements

At the opposite extreme, there's a republican proposal to create a new tax credit for health insurance. Hear me out. The only difference between a tax credit and an entitlement is whether the poor are eligible: people not rich enough to owe taxes are excluded from eligibility for tax credits, but are eligible to receive entitlement benefits. The Paul Ryan plan is already most of the way to entitlement, making the tax credit "universal advanceable, refundable," paid out monthly. But consider the political math:

Without legislating the fixed tax credit now, Condeluci said, Republicans "may never get Democrats to be supportive of a fixed tax credit that varies by age. And maybe Republicans know that a fixed credit is not going to be enough for a low income person. They know that at some point they're likely to put into law some kind of income-based subsidy for low income folks. Are they maybe going to hold that negotiating piece as a chip to get Democrats to the table and to agree on replace? Condeluci, in other words, envisions an eventual hybrid in which low income people get income-based support to render coverage affordable, while the somewhat more affluent -- or maybe everyone who buys in the individual market -- get a fixed tax credit to defray some of the cost.

Given that the president-elect is promising that no one who has insurance will be left without insurance, and that a flat tax credit would be obviously inadequate for lower-income households, it seems fairly likely that an income-based subsidy would be included in any tax credit plan. That in turn means that regardless of income, everyone would receive a federal subsidy to offset a large portion of their health insurance premiums--in other words, a massive new entitlement program. There's precedent, too. In 2003 Republicans hatched the Medicare Prescription Drug, Improvement, and Modernization Act, which created a new federal entitlement for seniors known as Medicare Part D. It may not be likely, but don't discount the possibility that Republicans end up outflanking democrats on the left instead of right, it has happened before.

¯\_(ツ)_/¯

So there you have it. Republicans have narrowed the health policy options to the range between complete destruction of the individual market and a massive expansion of entitlements.

Yesterday at 2pm the CBO released a big report with estimates for lots of different budget options. I reviewed the health-related ones.

But first, a disclaimer: there's less health policy in the CBO releases than you might expect. You won't, for example, find much analysis on how federal health programs affect mortality, or estimates of the cost-effectiveness of public health insurance, nor even ideas for reducing the cost of delivering care to medicaid enrollees. So, don't think of this CBO document as being about policy. More realistically, you should think of it as a list of possible "pay fors" that the next congress can fish to offset the cost of new deficit-increasing policies republicans would like to enact.

Relatedly, there's very little in the CBO estimates that represents genuine "savings" to the government—most of the deficit reduction comes from proposed tax hikes. Sometimes this is explicit: one of the largest budget items in there is the proposal to tax 50 percent of the value of employer-sponsored health insurance plans, which would raise $430 billion over the first decade. Other times, this is implicit, such as the proposals to raise deductibles for medicare, VHA, and trihealth beneficiaries—after all there's little practical difference, for example, in raising the Medicare part A premium versus levying a tax on social security income. Other proposals include a mix of policy design, spending cuts, and tax hikes, such as the proposals to hike copays and coinsurance to medicare, which in addition to producing revenue, should also reduce hospital stays and other healthcare utilization by beneficiaries. So, there are some actual policy ideas in there, and a couple of them are pretty decent.

Federal Employees

Here's a pretty typical proposal in the genra: a plan to replace the Federal Employee Health Benefit with a voucher tied to inflation. There's very little policy here, as federal employees already shop for private insurance plans in the FEHB system. Rather, this is just a reduction in pay to federal employees: by tying the value of the health benefit to inflation (there's no good reason to suppose health costs won't grow faster than inflation), this proposal reduces federal payrolls by about $58 billion over ten years. This could be equivalently phrased as a revenue enhancement: a tax on federal employees. This is why I say we should think of these CBO options as a pond where Congress can go fish for money, not serious policy analysis.

CBO estimates that applying the same medigap restrictions (see below) to the military health benefit, Tricare, would save $27 billion. Most of this, about three fifths, savings comes from reduced benefits to beneficiaries (cost shifted from government to beneficiaries), while the remaining two fifths comes from reduced healthcare utilization. Also like the Medicare reform, this would cap out-of-pocket expenses at $4,125, making it a decent policy trade. Still though, "soldiers are overpaid" is not complaint I hear often—why not refund that $27 billion to them in the form of lower premiums?

You can save $29 billion by repealing VA health benefits for 2 million veterans. Half of those veterans will end up on other forms of public insurance such as medicaid or else receiving federal subsidies for Obamacare, while the other half will ¯\_(ツ)_/¯. These aren't veterans with disabilities, so ideally they'd be able to get health insurance through their post-military employment in private businesses.

Here's $18 billion if you raise premiums, deductibles, co-payments for veterans. There's no breakdown of how much is revenue/out-of-pocket versus how much is reduction in healthcare utilization, though we can safely assume most of it is the former. Hiking premiums makes Tricare less attractive relative to private insurance options, which I guess is desirable if you prefer they seek private insurance instead of a federal retirement benefit. On the other hand, this undermines the goal of keeping Tricare as a safety net for veterans who cannot afford private insurance.

Medicare

Here's a proposal to modernize Medicare by capping out-of-pocket payments at $7,500 while raising the part A coinsurance to match part B's 20 percent, and adding a $250/day copayment for the first 5 days of hospital stays. That contrasts sharply with the current weak design of Medicare that not only doesn't cap out of pocket costs, but actually increases them for the sickest patients. The strengths of this policy design, however, are undermined by the need to raise revenue—rather than using the savings from decreased moral hazard and the revenue from co-pays and coinsurance to reduce premiums, the plan hikes premiums, imposing a $19 billion tax on seniors. But why?

Additional Medigap option: There's also an alternative in the above proposal to produce even more savings by restricting medigap policies so that can't pay for all of a senior's medicare copays and coinsurance. Under the restrictions, medigap could not cover the first $750 of patients' out-of-pocket medicare expenses, and no more than 50 percent of expenses over $750 but under $6,750, and this saves $45 billion over six years. Overall this is a dumb plan because it does not include other types of supplemental insurance such as employer benefits, but the estimates they have are noteworthy: in the first year, 2020, there will be 40 million fee-for-service enrollees and 20 percent of them will have medigap, and the CBO estimates restricting those medigap plans will save $4.9 billion, for a total of $6,125 in savings per beneficiary. Note that average Medicare spending is only $10,000 per beneficiary. CBO says they used similar behavioral estimates as RAND but a 60 percent reduction in healthcare utilization is quite a ways away above RAND estimates. It also doesn't seem consistent with estimates they used for the out-of-pocket cap above.

Here's a $330 billion tax hike on seniors, in the form of increases in premiums for Medicare part B and part D.

Medicare compensates healthcare providers for 65 percent of certain medical debts that patients can't pay. Reducing that to 45 percent saves $15 billion, and reducing it further saves $31 billion. To an extent, this is just a plan to tax healthcare providers, though I suppose they'll make up a portion of the loss by not treating poor patients, and squeezing those who struggle to pay even harder.

Here's medicare part D rebate program that looks to me a lot like a $145 billion tax on drug companies.

Medicaid

It turns out there's a loophole in federal medicaid funding to states that allows states to rope in more than the law intends. To simplify a bit, the federal government pays a percentage of medicaid expenses, and states levy special taxes on medicaid providers to artificially drive up measured medicaid spending, giving them more federal funding despite the fact that their actual medicaid expenses did not go up. This proposal narrows, but does not eliminate, this loophole, saving up to $40 billion over ten years.

But if that's not enough, it turns out that cutting medicaid by $374 billion saves almost $374 billion. Who knew? There's even less to this policy proposal than it sounds. There's no policy ideas about ways to reduce the cost of providing medicaid, but rather just a plan to reduce the pot of medicaid funds available to states. It does this specifically by imposing a per-beneficiary cap with annual increases pegged to CPI-U inflation rate, plus one percentage point, but the details hardly matter. The key point is that funding won't keep pace with healthcare costs, and this saves the federal government boatloads of money.

Graduate Medical Education

Now here's a plan to cut federal subsidies for Graduate Medical Education by $32 billion. Which, I guess I'm ok with? I've not found a convincing argument for why the government subsidizes this in the first place.

Medical Research

Here's a plan to reduce medical research by $9 billion. The premise of the plan is baloney—there's no analysis of the cost-effectiveness of the research, just a bogus argument that it doesn't belong in the Department of Defense. Ok, fine, let's move the money to NIH. Next?

Cigarette Tax

Ok, here's some real policy wonkery: a $0.50 per pack tax hike on cigarettes would raise $34 billion in revenue, and over the first decade save an additional billion in reduced public health expenses. After 10 years, as those healthier people live longer that $1 billion savings is likely to turn slightly negative. But besides, the reason to do this is the benefit to public health, not the revenue or savings.

Capping Malpractice Damages

I'm a little confused on how this proposal works, but it looks like capping medical malpractice suits at $750,000 (up to $500,000 punitive plus $250,00 pain and suffering) plus an unlimited amount of economic damages (lost wages, etc) saves about $62 billion due to reduced cost of medicare, medicaid, FEHB, and Obamacare subsidies. This strikes me as a large estimate when you consider that it only happens if the decreased malpractice liability causes both doctors to reduce prices and insurers to pass that savings to enrollees, for a net reduction in total national health spending by 0.5 percent.

Obamacare

If you repeal Obamacare's expenses but not it's funding sources, you have a pot of $1.2 trillion to play with.

On the other hand if you just want to end the individual mandate, that's $416 billion in savings on Obamacare subsidies as people become uninsured. To be honest, that's more than I would estimate, as my view is that the subsidies themselves are a larger incentive to stay in the market than the mandate.

No.

Ok, there is one paper that suggests, yes maybe a little tiny bit. From the abstract:

Results indicate that consumer voters were attracted to states with higher per pupil public school spending, lower property and income tax rates, and that certain consumer-voters may be attracted to states that offer higher levels of Medicaid benefits.

This paper studied pre-ACA data and found a small marginally significant correlation between per-capita medicaid expenditure and net migration. But the paper doesn't use a particularly convincing strategy for causal identification—correlation is not causation, as they say, and in any case the correlation with medicaid was among the weakest they found in the data.

Two other papers have studied the effects of various expansions of medicaid on migration, using much stronger methods for causal inference. Here's Schwartz and Sommers (2014) studying pre-ACA expansions in several states:

Using difference-in-differences analysis of migration in expansion and control states, we found no evidence of significant migration effects. Our preferred estimate was precise enough to rule out net migration effects of larger than 1,600 people per year in an expansion state. These results suggest that migration will not be a common way for people to obtain Medicaid coverage under the current expansion and that interstate migration is not likely to be a significant source of costs for states choosing to expand their programs.

And here's Goodman (2016) with an analysis of the ACA expansion specifically:

Using an empirical model in the spirit of a difference-in-differences, this study finds that migration from non-expansion states to expansion states did not increase in 2014 relative to migration in the reverse direction. The estimates are sufficiently precise to rule out a migration effect that would meaningfully affect the number of enrollees in expansion states, which suggests that Medicaid expansion decisions do not impose a meaningful fiscal externality on other states.

Based on my brief search of the literature these are the only papers on the effect of medicaid on migration specifically, though a much larger literature exists on the effects of welfare programs more generally, usually finding small effect sizes.

The migration literature, including the first paper above, does find that tax policies have a significant effect on migration, with higher taxes causing lower net migration to those localities, consistent with the theory that people move to avoid taxes. It's not hard to guess why taxes would have much larger effects than welfare generosity: the rich who pay taxes can afford to move, while the poor who receive welfare cannot. There are two ways of interpreting this disparity in migration effects. On the one hand, the fact that medicaid doesn't induce migration relaxes incentive compatibility constraints, allowing more efficient redistribution, while on the other hand the high effects of taxation on migration exacerbates these constraints, prohibiting states from being able to finance as much redistribution as they otherwise prefer.
