I brought up in a prior thread that this paper reminded me of a JMP I read while serving on a hiring committee. The recent bump of the Spiess JMP thread reminded me of this and led to some digging on my part.
"In Sickness and in Health: The Influence of State and Federal Health Insurance Coverage Mandates on Marriage of Young Adults in the USA" by Scott Barkowski and Joanne Song McLaughlin (2018). The paper claims to be the first to gather a set of laws on state dependent mandates.
The un-referenced work is "New Evidence on the Effects of Dependent Coverage Mandates" by Aaron Gamino who assembles what looks to be a similar set of laws. I found his application materials and a October 2016 version of the paper. A google scholar search locates a 2017 dissertation and a 2018 working paper of the same paper. I did not find the 2016 version online but I did not expend much effort searching.
Is this another example of a strategically omitted citation or a less-than-thorough job of reviewing existing literature? Barkowski has a reputation to oversell the importance of his work and is facing tenure review which could provide motivation to boost his paper's contribution via a strategically omitted citation. My interactions with Joanne have been pleasant and she does not strike me as one to omit a citation due to negligence or for self-promotion.
