This article seeks to explain the large decline in drinking and driving that occurred in the United States during the 1980s and 1990s. Using a simple measure of drinking and driving—the fraction of crashes involving drinking drivers—we develop a basic traffic safety model that improves estimates of drunk driving laws' effects and breaks down declines in drinking and driving into components associated with each major influence that has been identified in the literature—including unobservable “social forces.” In this decomposition, we find that the widespread enactment of seven major drunk driving laws explains only one-fifth of the reduction in drinking and driving over this period, comparable to the effects of reduced alcohol consumption and less than those of demographic shifts and changes in social attitudes. “The Other Great Moderation” is best understood as a two-decade movement of drinking and driving to a new steady state, led by social forces and cemented and extended by law.

了解“另一个大节制”期间酒后驾驶的下降

本文试图解释 1980 年代和 1990 年代在美国发生的酒后驾驶大幅下降。使用一个简单的酒后驾驶测量方法——涉及酒后驾驶的事故比例——我们开发了一个基本的交通安全模型，该模型改进了对酒后驾驶法律影响的估计，并将酒后驾驶的下降分解为与每个主要影响相关的组成部分。在文献中被识别——包括不可观察的“社会力量”。在此分解中，我们发现七项主要酒后驾驶法律的广泛颁布仅解释了这一时期酒后驾驶减少的五分之一，与减少饮酒的影响相当，但低于人口变化和变化的影响。社会态度。
