My paper with Kerstin Enflo: "Causality between energy and output in the long-run" has been accepted to be published in Energy Economics. In this case, the published paper will only differ slightly from the working paper version, which I have already blogged about. This is mainly because we only put up the working paper after getting a revise and resubmit from the journal. The question of when to post a working paper is something I have discussed on the blog and thought about quite a bit. We just got a revise and resubmit on this working paper. Our plan, is to add some additional analysis to answer the referees concerns. Even if we end up updating the database the final paper will not be radically different. There are other cases where we completely changed the dataset in response to referee comments. So, in that case, our first working paper was a bit premature.
