Marginal Productivity of Expanding Highway Capacity

Journal of Transport Economics and Policy, 2012, vol. 46, issue 3, 333-347

Abstract: This paper examines the contribution of highway capacity expansions towards regional economic development in the US. Using data for the forty-eight contiguous US states from 1984 to 2005, the dynamic production function estimates reveal that increases in overall highway capacity in states can have a positive, long-lasting effect on private sector output. However, both short-run and long-run output elasticities of highways are small. The data suggests further investments in highway infrastructure may not produce sizable economic returns. The estimates of the long-term productivity benefits of capacity expansion appear to be even smaller for lane-mile additions of lower functional road categories. © 2012 LSE and the University of Bath
