Ownership and exit behavior: evidence from the home health care market

In the US health care system a high fraction of suppliers are not-for-profit companies. Some argue that non-profits are “for-profits in disguise” and I test this proposition in a quasi-experimental way by examining the exit behavior of home health care firms after a legislative change considerably reduced reimbursed visits per patient. The change allows me to construct a cross provider measure of restriction in reimbursement and to use this measure and time-series variation due to the passage of the law in my estimates. I find that exits among for-profit firms are higher than those of not-for-profit firms, rejecting the null that these sectors responded to the legislation in similar ways. In addition, my results expand the view that “not-for-profit” firms are a form of “trapped capital.” There is little capital investment in the home health care market, so the higher exit rates of for-profit firms after the law change indicate the possible role of labor inputs in generating differences in exit behavior across sectors.
