Redistribution, Inequality, and Growth. Jonathan D. Ostry, Andrew Berg, and Charalambos G. Tsangarides. February 2014.

“Economists are increasingly focusing on the links between rising inequality and the fragility of growth. Narratives include the relationship between inequality, leverage and the financial cycle, which sowed the seeds for crisis; and the role of political-economy factors (especially the influence of the rich) in allowing financial excess to balloon ahead of the crisis. In earlier work, we documented a multi-decade cross-country relationship between inequality and the fragility of economic growth. Our work built on the tentative consensus in the literature that inequality can undermine progress in health and education, cause investment-reducing political and economic instability, and undercut the social consensus required to adjust in the face of shocks, and thus that it tends to reduce the pace and durability of growth. That equality seems to drive higher and more sustainable growth does not in itself support efforts to redistribute. In particular, inequality may impede growth at least in part because it calls forth efforts to redistribute that themselves undercut growth. In such a situation, even if inequality is bad for growth, taxes and transfers may be precisely the wrong remedy.”
