Using publicly available cost report data from the National Academy for State Health Policy Hospital Cost Tool for short-term hospitals from 2011 through 2019, this study compares hospitals with exactly two neighbors within sixty miles that experienced a neighboring closure to those retaining two neighbors, ensuring comparable baseline market structure. For-profit hospitals show the largest post-closure increases in charge-to-cost ratios and net profit margins. Nonprofit hospitals show smaller gains, while governmental hospitals show changes indistinguishable from zero, motivating ownership-differentiated policy responses.
