The pricing of cosmetic surgery procedures has long been thought to coincide with laws of basic economics, including the model of supply and demand. However, the highly variable prices of these procedures indicate that additional economic contributors are probable.
The authors sought to reassess the fit of cosmetic surgery costs to the model of supply and demand and to determine the driving forces behind the pricing of cosmetic surgery procedures.
Ten plastic surgery practices were randomly selected from each of 15 US cities of various population sizes. Average prices of breast augmentation, mastopexy, abdominoplasty, blepharoplasty, and rhytidectomy in each city were compared with economic and demographic statistics.
The average price of cosmetic surgery procedures correlated substantially with population size (r = 0.767), cost-of-living index (r = 0.784), cost to own real estate (r = 0.714), and cost to rent real estate (r = 0.695) across the 15 US cities. Cosmetic surgery pricing also was found to correlate (albeit weakly) with household income (r = 0.436) and per capita income (r = 0.576). Virtually no correlations existed between pricing and the density of plastic surgeons (r = 0.185) or the average age of residents (r = 0.076).
Results of this study demonstrate a correlation between costs of cosmetic surgery procedures and local economic factors. Cosmetic surgery pricing cannot be completely explained by the supply-and-demand model because no association was found between procedure cost and the density of plastic surgeons.
长期以来，人们一直认为整形手术的定价符合基本经济学规律，包括供需模型。然而，这些手术价格的高度变异性表明可能存在其他经济因素。
作者试图重新评估整形手术成本与供需模型的契合度，并确定整形手术定价背后的驱动因素。
从美国15个不同人口规模的城市中各随机选取10家整形手术机构。将每个城市隆胸、乳房提升术、腹部整形术、眼睑整形术和除皱术的平均价格与经济和人口统计数据进行比较。
在美国15个城市中，整形手术的平均价格与人口规模（r = 0.767）、生活成本指数（r = 0.784）、自有房产成本（r = 0.714）和租房成本（r = 0.695）密切相关。还发现整形手术定价与家庭收入（r = 0.436）和人均收入（r = 0.576）存在相关性（尽管较弱）。定价与整形外科医生的密度（r = 0.185）或居民平均年龄（r = 0.076）之间几乎没有相关性。
本研究结果表明整形手术成本与当地经济因素之间存在相关性。整形手术定价不能完全由供需模型来解释，因为未发现手术成本与整形外科医生密度之间存在关联。
