Abstract
The purpose of this paper is to examine ports growth, specifically whether or not port
growth is independent of port size. It uses total exports as a measure of size and use the
average as estimate of growth rate and specifically analyzes the growth rates of United
States Custom's Ports. Through using various tests, the findings conclude that larger
ports in the beginning of the period have higher growth rates than parts with lower total
exports at the beginning of the period. The conclusion of this finding is that physical
limitations inhibit a port's ability to grow, and thus larger ports have a higher growth
rate than smaller ports.
