A Supreme Court decision legalizing sports betting in the US led states to legalize sports betting in order to generate new tax revenues from wagering on sports events. Most states already permit other forms of gambling and receive tax revenues from these sources. The literature analyzing consumer substitution in gambling spending contains some evidence on the impact of expansions in many types of gambling, but no evidence on the impact of expanded sports betting. This paper exploits the legalization of sports betting and timing of sports book openings in West Virginia to analyze the impact of expanded sports betting on other casino gambling. Evidence using Instrumental Variables and difference-in-differences shows that increased consumer spending on sports betting caused a significant decline in spending on video lottery terminals (VLTs) in casinos, both of which generate tax revenues. Fiscal impacts include $2.6 million in new tax revenue from sports betting and a $45.4 million decrease in VLT tax revenues caused by expanded sports betting.

体育博彩、VLT 博彩和州博彩收入合法化：来自西弗吉尼亚州的证据

最高法院在美国将体育博彩合法化的决定导致各州将体育博彩合法化，以便从体育赛事的投注中获得新的税收收入。大多数州已经允许其他形式的赌博并从这些来源获得税收。分析赌博支出中的消费者替代的文献包含一些关于扩张对许多类型赌博的影响的证据，但没有证据表明扩大体育博彩的影响。本文利用西弗吉尼亚州体育博彩的合法化和体育书籍开张的时间来分析扩大体育博彩对其他赌场赌博的影响。使用工具变量和差异差异的证据表明，消费者在体育博彩上的支出增加导致赌场视频彩票终端 (VLT) 的支出显着下降，这两者都产生税收收入。财政影响包括来自体育博彩的 260 万美元新税收收入以及因扩大体育博彩而导致的 VLT 税收收入减少 4540 万美元。
