In this paper the author examines income differentials between board-certified and non-board-certified physicians to determine whether the trend toward board certification is consistent with economic incentives. Although simple income comparisons indicate substantial differentials by certification status, after adjustments are made for specialty-mix, age distribution, and hours worked, the remaining differential is small. However, results by specialty indicate that physicians are most likely to become certified in specialties with the largest income differentials.
在本文中，作者研究了获得委员会认证和未获得委员会认证的医生之间的收入差异，以确定委员会认证的趋势是否与经济激励相一致。尽管简单的收入比较表明，按认证状态存在显著差异，但在对专业组合、年龄分布和工作时长进行调整后，剩余的差异很小。然而，按专业划分的结果表明，医生最有可能在收入差异最大的专业中获得认证。
