HIGHWAY INFRASTRUCTURE INVESTMENT AND COUNTY EMPLOYMENT GROWTH: A DYNAMIC PANEL REGRESSION ANALYSIS*
利用北卡罗来纳州100个县1985-1997年的数据，采用动态面板计量方法分析高速公路投资对县级就业的影响，发现考虑内生性和动态调整后，高速公路改善对就业无显著影响。
ABSTRACT This paper uses recent advances in dynamic panel econometrics to examine the impact of highway infrastructure on aggregate county‐level employment using data for all 100 North Carolina counties from 1985 through 1997. Results are compared to models that do not take endogeneity of highway investment and dynamics of employment adjustment into account. Fully specified dynamic models are found to give insignificant results compared to these other models. Thus, when these issues are properly modeled, the results show that improvements in highways have no discernible impact on employment.
