A NOTE ON PUBLIC GOODS PROVISION AND COMMODITY TAXES

抄録

In this note, we investigated a rule for the optimal provision of public goods in a many consumerseconomy when an optimal commodity tax is available. We obtained an intuitive formulawhich demonstrates that divergence from the first best rule is based on (i) the revenue repercussioneffect, (ii) the Pigou-Harberger's dead weight loss effect, and (iii) the total distribution effectof public good provision. How this result relates to previous works was also analyzed. It was shown that our decomposition formula does apply even for the cost benefit approach employed in Batina (1990).
