post keynesianism and Joan Robinson

Order Description
1) Was Joan Robinson a Keynesian or Post-Keynesian? A response to this question will require

2) What are the distinguishing features of Post-Keynesian political economy? List at least 5.
3) Is Post-Keynesianism an extension of Keynes or a rejection of his thinking? Perhaps it is both. How would you characterise the Post-Keynesians in relation to Keynes?
