Three ways of theorising ‘capture’ when politics and business join together

In the strongest-performing liberal democracies the separation of the political sphere from dominant or directly controlling business influences is protected by a range of ‘blocked exchanges’ (in Michael Walzer’s terms). But in authoritarian regimes, semi-democracies and flawed liberal democracies it is common for business interests to take control of the levers of political power acting alongside top politicians, with a joined-up elite or ‘oligarchy’ thereby ‘capturing’ the state. In different forms, this worldwide phenomenon can be seen from Russia to South Africa and from China to Brazil. Frank Vibert outlines three ways of looking at these situations, and stresses the difficulty of identifying and implementing a cure.
