The Scale and Efficiency of Government Redistribution: A Global Review

This paper provides a comprehensive review of the global evidence on the scale and efficiency of government redistribution. Challenging the conventional view of a rigid trade-off between equity and efficiency, it synthesizes the theoretical and empirical literature to show that the relationship between redistribution and economic performance depends on institutional design, the policy mix and administrative capacity. Methodologically, the paper is an integrative literature review: landmark studies identified through Google Scholar are combined with a structured search of Web of Science, Scopus and reports by international organizations, and the selected studies are screened against explicit inclusion criteria and synthesized thematically. The review yields four main findings. First, the scale of redistribution is considerablylarger than conventional estimates suggest, because in-kind transfers and indirect taxes substantially increase the measured redistributive effect of government activity. Second, the paradox of redistribution holds empirically: universal welfare states that provide benefits to all residents often reduce income inequality more than systems that target only the poor. Third, the efficiency of redistribution varies widely; efficiency frontier analysis shows that many governments could achieve the same reduction in inequality while spending considerably less. Fourth, several moderating factors determine whether scale and efficiency reinforce or undermine each other. The review also identifies important gaps in existing research concerning measurement, dynamic effects, new policy instruments, political economy and the specific conditions of developing countries. The paper concludes with policyimplications for designing welfare states that reduce inequality efficiently.
