The goal of an ongoing study conducted by the Federal Highway Administration and the Boston University Center for Transportation Studies is to quantitatively assess the direct, indirect, and induced economic effects of different categories of highway improvement projects. The first step in measuring the economic benefits of construction spending is to produce a profile of expenditures for different types of projects. This includes the number of employees and how much they earn; the tons of aggregate, cement, steel, and paving mix; the linear feet of guard rail and noise barriers; and the expenditure on lighting and traffic signals. Fortunately, there is a data resource that provides this sort of information. Form 47, Statement of Materials and Labor Used by Contractors on Highway Construction Involving Federal Funds, must be filed by the contractor upon completion of all federal-aid projects with construction costs exceeding $1 million. It was created for the purpose of tracking the economic impact of federal-aid highway expenditures and contains information on employment and quantities of various types of construction inputs. The final product of the study will be a software package to estimate the direct, indirect, and induced employment impacts of federal-aid highway program expenditures and state matching funds. With this software, it will be possible to anticipate national and regional economic effects associated with changes in the distribution of funds across states and across types of highway improvement projects. |
