At this rate, in any case?
Two things happened in the last twenty-four hours which made me wonder if some of the best economics blogs may be on their way out. First, an economist with a very high-quality blog told me that he was not sure if he had made the right decision by starting it. He said he worried about coming up with new content on a daily basis, and that he may run out of energy at some point. Then, Greg Mankiw declares that he is too busy to be reading and filtering all the comments he gets on his site and turns off the comments section. In a long post, he says the whole blog thing is taking too much of his time, and intimates that he may not be doing this for ever.
So if economists with high opportunity costs of time start to get out, shall we have a lemons problem on our hands? Will eventually the only prolific bloggers remain the ones that are not worth reading?
