Tax Harmonization and Tax Competition: Contrasting Views and Policy Issues in Three Federal Countries

This article contrasts divergent attitudes toward tax competitionand tax harmonization in Australia, Canada, and the United States.Despite strong arguments on each side, competition and harmonizationare not necessarily conflicting goals except at the extremes.The most troublesome issue is the tradeoff between promotingefficiency in the public sector and in the private sector. Dueto the difficulty of measuring and comparing efficiency in bothsectors, this issue is not likely to be resolved objectively.However, tax-base harmonization appears to be the best compromisein pursuing both goals. Some fundamental problems remain regardlessof the policy direction taken, including limiting "micro-level"competition and addressing environmental and redistributiveconcerns in regional and local arenas. Improved intergovernmentalcooperation and experimentation are viewed as the key to resolvingthese issues.
