In volume 35:2, authors explore a range of questions about the nature and effects of corruption in both its individual and institutional forms. Is there a conceptual link between personal corruption and institutional corruption? Can political corruption arise and persist without corrupt political actors? What are the micro-foundations of macro-corruption? How does corruption affect social and economic development? Is there a causal link between poverty and corruption — and in which direction does the causation predominantly flow? Can corruption improve economic performance? Can morality require acts of corruption? Is individual corruption excusable in a sufficiently corrupt system? This volume of Social Philosophy and Policy features papers by Mike Munger, Adrian Blau, Maria Ferretti and other leading thinkers to explore these important questions.
