Factors leading physicians to sign the 1984 Medicare participation agreement are assessed in this study. The decision was
highly sensitive to Medicare reimbursement levels. A 10-percent increase in the Medicare reasonable charge increased average
participation rates by 9.5 percent, or 3.2 percentage points (around the mean of 34 percent). Higher collection costs associated
with obtaining that payment from Medicare discourage participation, and physicians with large Medicare caseloads were more
likely to participate. Although board-certified physicians were no less likely to participate, graduates from non-English
speaking non-Western European medical schools were more likely to sign. Physicians in more liberal States and in areas with
greater health maintenance organization activity were significantly more likely to participate, as were those with lower malpractice
costs and weaker private demand.
