• 1. Introduction; 2. Geographic concentration and political mobilization by small and medium-sized business firms; 3. SME business association, multiparty legislature, and corruption; 4. Geographic concentration and national SME association in autocracies: the empirical evidence; 5. Empirical analysis of legislative institutions, SME firms, and corruption in autocracies; 6. Jordan: institutional change and corruption; 7. Malaysia: SME mobilization, and corruption; 8. Uganda: the contrarian case; 9. Conclusion and implications.

'Authoritarian regimes have few obvious reasons to check corruption: political opposition can be suppressed, formal accountability is weak, and corruption can be profitable for those at the top. But through data analysis and case studies Yadav and Mukherjee argue that as many as half of all such regimes have apparently reduced corruption to meaningful degrees. The lessons of this fascinating analysis are important for both corruption control and how we understand authoritarian systems: reform need not await democratization, and anti-corruption opportunities can be found in unexpected places.'
