Impacts of Highway Infrastructure Investment Under the American Recovery and Reinvestment Act

This study evaluated the impact on highway demand of highway disbursements under the American Recovery and Reinvestment Act (ARRA). Vehicle miles traveled were used to estimate a highway demand equation employing a spatial Durbin model for the 48 contiguous U.S. states during 1994-2008. Estimates from the equation were used to test the hypothesis that highway disbursements caused different upward shifts in the highway demand curves of states. We estimated $8.2 billion in total net benefits for the 48 states as a result of the $27.2 billion in ARRA highway disbursements, yielding an average net benefit of $0.30 per dollar spent.
