Estimation of cost functions for physicians firms is problematic because many physicians are self-employed, and the marginal opportunity cost of physician labor is not observed.
In this paper, we show how to recover marginal costs and conventional measures of economies of scales from cost functions that condition on the amount of physicians labor input.
In addition, we introduce the new concepts of marginal nonphysician input costs and bevavioral economies of scale, which reflect the structure of costs when physician labor input moves along a utility-maximizing expansion path.
Our results could be useful in the design of resource-based physician fee schedules.
