Dupuit, Pigou and cost of inefficiency in public services provision

In this paper we revisit the literature on the economic implications of inefficiency in public services provision. Most authors emphasize the need of changing public sector management practices and the scope of activities carried out by general government. Following Dupuit (1844) and Pigou (1947) we focus instead on the increase in the cost of public services’ provision, when indirect costs, associated with the excess burden of taxation, are taken into account. We rely on Hicks’ compensating variation (following Diamond and McFadden (1974) and Auerbach (1985)), and some public sector inefficiency coefficients from Afonso et al. (2005; 2006) to show that these magnification mechanisms are not only conceptually relevant, they are also important from a quantitative point of view.
