Abstract

In March of 2017 Utah announced its intent to lower the legal blood alcohol content (BAC) for driving from 0.08 to 0.05 g/dL. However, this change did not take effect until 2019. We employ a difference-in- differences strategy on Utah counties using neighboring states as controls to test whether this policy change significantly affected the number of traffic accidents or the severity of those accidents. Results show the policy appears to temporarily decrease the total number of accidents, limited primarily to property damage- only accidents. We believe these results may be partially explained by drivers who, after the policy is enacted, avoid reporting property damage-only accidents if possible. Using insurance claims data, we show there is no corresponding fall in insurance claims or payouts suggesting that the fall in total accidents likely comes from under-reporting.

饮酒......然后驾车离开:降低犹他州血液中酒精浓度的效果。
2017 年 3 月,犹他州宣布有意将驾驶时的法定血液酒精含量(BAC)从 0.08 克/分升降低到 0.05 克/分升。然而,这一变化直到 2019 年才生效。我们对犹他州各县采用差异策略,以邻近州作为对照,检验这一政策变化是否对交通事故数量或事故严重程度产生重大影响。结果显示,该政策似乎暂时减少了事故总数,但主要限于财产损失事故。我们认为,这些结果的部分原因可能是政策颁布后,驾驶员尽可能避免报告仅造成财产损失的事故。利用保险索赔数据,我们发现保险索赔或赔付率并没有相应下降,这表明事故总数的下降很可能是由于报告不足造成的。

期刊介绍: This Journal publishes articles on all aspects of health economics: theoretical contributions, empirical studies and analyses of health policy from the economic perspective. Its scope includes the determinants of health and its definition and valuation, as well as the demand for and supply of health care; planning and market mechanisms; micro-economic evaluation of individual procedures and treatments; and evaluation of the performance of health care systems. Contributions should typically be original and innovative. As a rule, the Journal does not include routine applications of cost-effectiveness analysis, discrete choice experiments and costing analyses. Editorials are regular features, these should be concise and topical. Occasionally commissioned reviews are published and special issues bring together contributions on a single topic. Health Economics Letters facilitate rapid exchange of views on topical issues. Contributions related to problems in both developed and developing countries are welcome.
