There is no such thing as “the market economy”. Markets come in many varieties and their character is a matter of political choice. Saying that a market is politically shaped is simply to state the obvious, namely that any economic market is first political and then economic. A politics-free market does not exist in the real world outside of standard economics text-books or, paradoxically perhaps, in the prevarication of politicians who deny its political component precisely for political reasons. So, if markets are irreducibly political, we need to ask what values should guide their political construction. The Democratic Wealth series has given much attention to ‘republicanism’ as a philosophical tradition which might serve as a source of guidance (see, for example, these contributions from Alex Gourevitch, José Luis Martí and Philip Pettit). But which republicanism?
