Opportunities and challenges for post-Keynesian economics?

The current situation offers great opportunities for Post Keynesians to offer a persuasive alternative to mainstream economics. This chapter explores these opportunities and the Post-Keynesian ideas of long standing for alternative theories and policies. The focus is put on two controversial issues which arise when considering the best route forward: the place, respectively, of mathematical modelling and pluralism. It is argued that Post-Keynesian modelling be considered as part of a pluralist methodology, as against dualism: the only-modelling and no-modelling positions. It is also argued that Post Keynesianism should be pursued, not only with a pluralist methodology, but also within a pluralist landscape alongside other schools of thought. This is quite compatible with Post Keynesians trying to persuade others that their approach is better than alternatives to understand reality.
