Do Public-Private-Partnership-Enabling Laws Increase Private Investment in Transportation Infrastructure?
研究了美国各州公私合作授权法对私人投资的影响，发现税收豁免、采购法豁免和保密条款等规定能吸引私人投资。
The use of public-private partnerships (PPPs) is an important development in infrastructure delivery. These contracts between a public-sector owner and a private provider bundle delivery services and provide a middle ground between traditional delivery and privatization. As of 2016, 35 states had enacted PPP-enabling laws that address such questions as the mixing of public- and private-sector funds, the treatment of unsolicited PPP proposals, and the need for prior legislative contract approval. We provide the first comprehensive empirical assessment of the laws’ impact on the utilization of private investment. We analyze the effect of a state having a PPP-enabling law and a law’s average impact. We also assess the impact of PPP-enabling-law provisions. We find that provisions that empower PPPs, such as exemptions from property taxes, exemptions from extant procurement laws, and confidentiality protections, attract private investment.
