Controlling Automobile Insurance Costs
概述了汽车保险系统和市场结构，分析了1980年代保费上涨的原因，发现主要源于成本因素特别是人身伤害索赔严重性通胀，而非利润率或费用增加，最后提出控制成本的建议。
We begin by providing an overview of the auto insurance system and the structure of the auto insurance market. We then turn to an analysis of the factors underlying the auto insurance price increases experienced in recent years. We find that the auto insurance inflation of the 1980s was caused primarily by increases in cost factors, especially inflation in the severity of personal injury claims. There is no persuasive evidence that increasing profit rates or expense loadings contributed to inflation in premiums. The paper concludes with recommendations for bringing costs under control.
