Countries with a high level of public investment relative to output experience higher productivity growth than other countries. Thus, Japan with a 5.1% investment in public works achieved a productivity growth of 3.1%, and the U.S with an investment ratio of 0.3% had a productivity growth of 0.6% per year. Public investment in U.S. highway and bridge network has declined to 0.7% of GNP in 1988. In the same year Japan spent more than 1.8% of its GNP on highway infrastructure improvements. It is pointed out that the U.S. is not providing the necessary roadwaay capacity to ensure sound economic growth within the nation and is placing itself at a competitive disadvantage.
