Transportation Investment and Job Creation in Minnesota Counties
Zhirong Zhao, Associate Professor, Humphrey School of Public Affairs
Project Summary:Numerous studies have been conducted about the impact of transportation investment on economic development. These studies typically use a conventional production function model of economic development augmented by a public capital input such as highways, rail, or other transportation investments. The findings, in general, confirm a positive elasticity between transportation investment and economic development, but the range of the effects varies widely among studies. In a recent research project, Zhao quantified long-term transportation capital stocks in Minnesota counties and found that these stocks have positive returns on property values. This study extends Zhao's methodology to study the link between transportation investment and job creation, and it found that long-term transportation investments contribute significantly to employment in Minnesota counties. The results have several policy implications. First, investments on local roads within a county can increase the employment rate in the county. Second, investments on trunk highway surrounding a county can increase the employment rate in the county. Lastly, in the context of Minnesota and as far as employment growth is concerned, it could be more effective to invest in rural areas compared to urban areas.
