This paper addresses the issue of hospital bed capacity by considering
the stochastic demand for United States hospitals. An equilibrium con
dition for the optimal number of ''excess'' beds is derived and applie
d using a cost function estimated with a panel data model for the peri
od 1987-1992. Results indicate that it may be difficult to justify the
costliness of existing levels of empty hospital beds. The Department
of Justice and the Federal Trade Commission should be cognizant of the
potential effects of hospital mergers on undesirable excess bed capac
ity.
