Assume you are an AP a few years out and your JMP is forthcoming in JF.
You want to exploit your knowledge of the topic as much as possible.
You write a couple of follow-up papers (i.e. extensions of a model, applications of the idea to a different context, etc etc).
What is the best way to publish those papers? how do you avoid that a referee kills you saying that the marginal contribution with respect to the JMP is small?
