The origin principle, tax harmonization and public goods

This paper takes up two tasks. Firstly, it shows that the conclusion drawn in Lucas (2001) [Lucas, V., 2001, Tax harmonisation and the origin principle, Economic Letters, 71, 111–115.] regarding potential Pareto improvement in small open economies needs to be amended. Secondly, in large open economies, it verifies that some reasonable conjectures, concerning the welfare effects of a particular tax-harmonizing reform, hold under the origin-based tax system when public goods are present
