Abstract:The growth of health care costs and expenditures recently led to suggestions for innovations that would affect demand for health care. However, supply side issues were largely ignored in the debate despite the fact that the American Medical Association has controlled entry since it was granted that power by legislators early in this century. We consider the supply side of the market for physicians' services over 1983–1991. Our estimated index of market power indicates nontrivial power among physicians. This suggests that conventional policy tools could reduce costs in this market. This, in turn, could effectively lower insurance premiums.
