       | consists of 4.5 million returns, corresponding to 8.9 million
       | individuals."
       | 
       | Those in the treatment group were 1.3[1] percentage points more
       | likely to enroll in coverage in the year following the
       | intervention than those in the control group: about 50,000 extra
       | households (~100,000 extra people) were signed up due to the
       | letter.
       | 
       | So, about 200 died because they didn't receive the letter (But
       | that was offset by the 8 billion lives that were saved by
       | something else that didn't happen that day.).
       | 
       | [1] "those in the treatment group were 1.3 percentage points more
       | likely to enroll in coverage in the year following the
       | intervention than those in the control group, a 2.8% relative
       | increase. On average, each letter increased coverage among this
       | group by 0.14 months during 2017, or one additional year of
       | coverage per 87 letters sent. We document larger effects among
       | individuals who lacked any coverage during the prior year and
       | among older non- elderly adults."
       | 
       | Edited: corrected numbers - mistook households for individuals.

           | taxpayer(s), was sent per return. Hence, randomization was
           | conducted at the household level."
           | 
           | So 86% of 4.5 million households were sent a letter, and that
           | led to a 1.3% percentage point increase in signups compared
           | to the 14% of households that were not sent a letter. They
           | are then saying that those 1.3% of extra signups led to
           | saving ~700 lives. There is the risk of a selection bias
           | because we don't know why those extra 1.3% signed up versus
           | those that didn't.
           | 
           | The actual paper uses months, since everyone dies, so zero
           | lives can be saved in the long term.

           | Seems there has been some prior evidence for supporting the
           | idea that health insurance (the only way to get affordable
           | healthcare in the US) matters.
           | 
           | What are examples of studies that show it has little to no
           | impact?

         | 
         | So with those combined, it means the impact of coverage on
         | mortality is small enough that its hard to measure. Of course
         | avoiding financial catastrophe is also a good reason for some

         | are low.

           | 
           | But then there's also the secondary effects, like losing your

           | Another reply asserted that studies say it doesn't help much,
           | but... that's just so counter intuitive to me that the the
           | studies that were replied there saying actually it does help
           | can be summarized by "well, duh".
           | 
           | But I've thought "well, duh" about false things in the past,
           | which is why I want to know.
