Could republicanism provide the model for a political economy that belongs to us all and works for the common good? OurKingdom and Politics in Spires’ new series explores this question, introduced here by its editor. The past two decades or so have seen a renewal of interest within academic political theory in something, or some things, called ‘republicanism’. As a tradition (or set of traditions) within political theory, republicanism is not going to give us a direct handle on, say, the details of monetary and fiscal policy. But it can perhaps provide a constructive basis for thinking about what we fundamentally want from an economic order and about some of the institutions or approaches that will promote these goals.
