Econ Bloggers

From Tyler Cowen:

Econ bloggers gain clout in financial crisis, Marginal Revolution: Here is the article, there is lots from me and from Mark Thoma, among others.

On a more casual note, I've enjoyed blogging the same topic week after week after week.  I wonder at what point I will feel like cracking?

I'm not sure the quote about doctors came out quite right:

Are the econ bloggers able to better explain and analyze the often-complex factors that have led to the current crisis?

"I'm in academics," he replied. "On the academics side, you don't ever diagnose the patient. It's all theoretical, and what I'm doing now, especially with the financial crisis, is like having a patient show up at the doctor's office and say, 'I've got these symptoms, what's wrong with me?' And the doctor sticks him. That's a completely different use of economics -- a real time analysis -- that I haven't seen before."

Instead of "and the doctor sticks him," I meant that the doctor is asked to diagnose what is wrong and recommend a prescription - a cure of some sort - that will fix the problem (or explain why no cure is available and the patient will have to suffer through the problem until it fixes itself). You don't have the luxury  you have as an academic of waiting until it's all over, looking at the data, and then figuring out how well the policy worked, what could have been done better, etc. Part of real-time policymaking is learning what to look at ("Get me a TED spread, stat!"), and then learning how to interpret the diagnostics that you get so that you can understand what is happening and recommend a course of action. Real-time policy making is not easy, and you find out very fast just how good your models really are, and I've gained a lot of respect for those who do it and do it well since I've started doing this.

As in the medical profession, we need an interface between theory and practice - in economics the gulf has been too wide for too long - and I think blogs are one way the profession has started to close the gap between the theoretical community and policymakers. Practitioners have a lot to learn from the theoretical research in medicine and in economics, but there also has to be a feedback in the other direction where the practitioners can say, "this treatement doesn't work, has the following flaws, etc., and it would work better if..." so that the theorists can provide better tools for polcymakers and other practitioners. The Fed and other policymaers have always had to do this - make policy decisions in real-time - but the process wasn't very visible. With blogs, it's starting to come out into the open, e.g. look what Krugman did on his as policies to abate the financial crisis were proposed, and I think that's a very healthy development.
