Evaluating State and Local Business Incentives
评估美国州和地方的企业税收激励措施，发现2014年各州人均激励支出差异大，高激励州公司税率更高，但企业特定激励对整体经济增长的促进作用证据不足。
This essay describes and evaluates state and local business tax incentives in the United States. In 2014, states spent between $5 and $216 per capita on incentives for firms in the form of firm-specific subsidies and general tax credits, which mostly target investment, job creation, and research and development. States with higher per capita incentives tend to have higher state corporate tax rates. Recipients of firm-specific incentives are usually large establishments in manufacturing, technology, and high-skilled service industries, and the average discretionary subsidy is $178M for 1,500 promised jobs. Firms tend to accept subsidy deals from places that are richer, larger, and more urban than the average county, and poor places provide larger incentives and spend more per job. Comparing winning and runner-up locations for each deal, we find that average employment within the three-digit industry of the deal increases by roughly 1,500 jobs. While we find some evidence of direct employment gains from attracting a firm, we do not find strong evidence that firm-specific tax incentives increase broader economic growth at the state and local level.
