Come for the politics, stay for the snark.

Quote tweet friends, screenshot enemies.

Republicans: “Abortion is murder but you can take a bus to get one.” Easy peasy.

A democracy can’t function when people can’t distinguish facts from lies.

Prediction: the gop will rethink its strategy of boycotting future committees.

Never give a known liar the benefit of the doubt.

I have other things to bitch about but those will have to wait.

The line between political reporting and fan fiction continues to blur.

Insiders who complain to politico: please report to the white house office of shut the fuck up.

Russian mouthpiece, go fuck yourself.

The desire to stay informed is directly at odds with the need to not be constantly enraged.

Reality always lies in wait for … Democrats.

Boeing: repeatedly making the case for high speed rail.

Nothing worth doing is easy.

DeSantis transforming Florida into 1930s Germany with gators and theme parks.

If rights aren’t universal, they are privilege, not rights.

“woke” is the new caravan.

When we show up, we win.

Fight for a just cause, love your fellow man, live a good life.

Dear Washington Post, you are the darkness now.

Make the republican party small enough to drown in a bathtub.

My years-long effort to drive family and friends away has really paid off this year.

President Musk and Trump are both poorly raised, coddled 8 year old boys.

Let there be snark.

Hell hath no fury like a farmer bankrupted.

Oddities of competition

Last night, the Center for Medicare and Medicaid Services came out with their annual pre-Open Enrollment ACA data packet.  One of their big brag points is a legitimate increase in competition back on the ACA exchanges:

Table 1 shows PY17–PY21 QHP issuer participation and plan availability. In PY21 there are 181 QHP issuers participating in HealthCare.gov state Exchanges, an increase of 6 issuers from PY20 and an increase of 22 issuers when considering only states using HealthCare.gov in both PY20 and PY21. On average, PY21 enrollees have access to between 4 and 5 QHP issuers, which is greater than in PY17–PY20, and over 60 QHPs, which is greater than all previous years. Additionally, 4% of PY21 enrollees have only one available QHP issuer, which is the lowest percentage since PY16.

This makes sense. The ACA marketplaces are notably profitable with insurers consistently making well over the cost of capital in profits over the past few years. The ACA marketplaces are policy stable. The ACA marketplaces are politically stable (assuming the Supreme Court does not go YOLO on them). Profitable markets that are fairly predictable and stable with some states reinsuring against moderately high cost claims and federal catastrophic reinsurance is damn attractive. Insurers should expand. Insurers should enter new markets. This makes sense. This is a good brag point.

However… the ACA subsidy system does weird things with competitive markets. I want to highlight Figure 2:

Least Expensive Plan in each metal level CCIIO

The cheapest Silver plans for a subsidized buyer has gotten more expensive even as more competition is in the market.

THIS IS WEIRD!

It is also a direct result of the price linked subsidy system where the subsidy is attached to a dynamically generated value in each county.  That value is the price of the second least expensive silver plan.  Subsidized buyers are indifferent to price levels.  They are very sensitive to price spreads.  A monopolistic insurer can elect to create very large benchmark spreads.  This is a way to get to accidental and incidental single payer in some states.  These are short term price discounts as very profitable monopolistic markets should see new entries sooner rather than later.  In competitive counties/regions, insurers will price at least one of their silver plans as close to the bottom of the premium range as possible to increase the probability that they will get a good chunk of the CSR eligible and heavily subsidized population.  In both scenarios, the benchmark silver premium is the same, but the cheapest silver plan is way more expensive to subsidized buyers in competitive markets.  This is weird set of incentives and market design as competition does not help consumers on premiums; it may help on other attributes (network, plan type, customer service, unobservables etc) but not on price.

So more expensive cheap silver plans are a direct consequence of new entries into the market.

Interestingly, the cheapest gold to cheapest silver gap is shrinking.  We saw in California significant shift out of silver and to gold in 2018.  Gold’s absolute average cheapest premium is lower in 2021 than it was in 2018-2020 and the spread is lower, so I think we’ll see more movement to gold this year as well.

    Thanks for the explainer.  :-)

    Graphs like Figure 2 drive me nuts.  What is the time period of the premium?  Monthly?  Annual?  (I assume monthly.)

    Insurance in general seems to hate, hate, hate actually talking about time periods.  GEICO and Progressive and Elephant and … all talk about saving on premiums in their ads, but are they talking about over a 6 month policy or over a year??

    (sigh)

    Thanks.

    Cheers,
    Scott.

    This sentence made my brain hurt. I’m not smart enough to understand this stuff and that scares me, as I will probably have to go on the exchange in the next year. Thanks for pointing out HealthSherpa, though!

    Do you think this is a problem, and if so what would be a legislative solution? Your answer may assume a functioning legislature.

    Migrating more people into gold plans at prices close to silver is a good thing, yes it no? It seems like it should be “yes” since people are getting their care with lower copays and less risk of sudden huge medical expenses.
