The private nonprofit hospital is the dominant organizational form in
the U.S. hospital industry. Various reasons have been advanced for its
high market share, As hospitals undergo massive changes due in large
part to changes in payment practices, there is widespread concern that
nonprofit hospitals may become less committed to noncommercial activi
ties. This may even be more likely when such hospitals convert to non-
profit status. The empirical evidence indicates that, on average, hosp
itals of nonprofit and for-profit ownership are similar in the provisi
on of uncompensated care, the quality of care, and the adoption of tec
hnology. Conversion of a nonprofit to for-profit status does not adver
sely affect the provision of uncompensated cave on average. However, f
or-profits are more likely to be located in areas where consumers have
the ability to pay for care. As hospital markets become more competit
ive and the opportunity for cross-subsidizing more unprofitable, colle
ctive-good activities will become increasingly difficult. Support for
such activities, if they are to exist, will have to come from explicit
public subsidies.
