An empirical study on public capital spillovers from the USA to Canada
The effect of public capital on private sector productivity has received much attention in the literature. The impact of an adjacent country's public capital on domestic productivity has, however, not been previously examined. This paper attempts to fill this gap by examining the possibility of such spillovers from the USA to Canada. Due to close proximity of both countries, the hypothesis of the paper is that these spillovers are important. A production function model introduces US public capital as an exogenous variable and tests for its significance. The results indicate positive spillovers from the USA public capital to Canadian productivity.
