Three finance researchers, Pengjie Gao of Notre Dame and Chang Lee and Dermot Murphy of the University of Illinois Chicago, went looking for this in municipal bond data and published what they found in the Journal of Financial Economics in 2020. In the three years after a closure, offering yields on that municipality’s bonds rose 5.5 basis points, and secondary market yields rose 6.4.
