And why you should too.

There is a painful non-convexity in academic research.  Only really good ideas are worth pursuing but it takes a lot of investment to find out whether any given idea is going to be really good.  Usually you spend a lot of time doing some preliminary thinking just to prove to yourself that this idea is not good enough to turn into a full-fledged paper.  Knowing that most ideas are unlikely to pan out there is an incentive not to experiment on new projects.

Blogging bridges that gap in a way I didn’t expect when I started.    Blogging means that half-baked ideas have scrap value:  if they are not publishable you can at least write about them on the blog.  This means that you are more likely to recoup some of those costs of experimentation and you undertake more projects ex ante.

So, readers, don’t thank me for blogging (not that I thought you had any good reason too.)  I thank you for wading through the scraps.
