Using monthly data from the 2014–2016 Survey of Income and Program Participation, I estimate duration-specific effects of displacement on each coverage source with a difference-in-differences design. ESHI coverage falls by 15 to 18 percentage points within a few months of displacement, with only slight recovery over the following year. Medicaid enrollment increases modestly, driven entirely by workers in expansion states where coverage increases exceed 7 percentage points. Directly purchased private insurance shows no discernible response despite marketplace availability and premium subsidies, and this holds across income levels. These findings indicate that ACA marketplace reforms in the sample period provide limited protection for displaced workers.</p> Shrinking Populations, Aging, and Access to Healthcare https://katsuhiko-nishiyama.github.io/papers/mypaper2/ Thu, 08 Jan 2026 00:00:00 +0000 https://katsuhiko-nishiyama.github.io/papers/mypaper2/ <hr> <h2 id="download">Download</h2> <p>TBA</p> <!-- - [Paper](ESHI_paper.pdf) --> <hr> <h2 id="abstract">Abstract</h2> <p>TBA</p> <hr> <h2 id="citation">Citation</h2> <p>TBA</p> <hr> <h2 id="related-material">Related material</h2> Medical Debt, Self-Insurance, and the Value of Health Insurance for the Non-Elderly https://katsuhiko-nishiyama.github.io/papers/mypaper1/ Wed, 22 Oct 2025 00:00:00 +0000 https://katsuhiko-nishiyama.github.io/papers/mypaper1/ <hr> <h2 id="download">Download</h2> <ul> <li><a href="ESHI_paper.pdf">Paper</a></li> </ul> <hr> <h2 id="abstract">Abstract</h2> <p>TBA</p> <hr> <h2 id="citation">Citation</h2> <p>TBA</p> <hr> <h2 id="related-material">Related material</h2> Medical Debt and Access to Hospital Care https://katsuhiko-nishiyama.github.io/papers/mypaper4/ Wed, 24 Apr 2024 00:00:00 +0000 https://katsuhiko-nishiyama.github.io/papers/mypaper4/ <hr> <h2 id="download">Download</h2> <p>TBA</p> <!-- - [Paper](ESHI_paper.pdf) --> <hr> <h2 id="abstract">Abstract</h2> <p>TBA</p> <hr> <h2 id="citation">Citation</h2> <p>TBA</p> <hr> <h2 id="related-material">Related material</h2> False Alarm?
