A recent post by Lord Keynes inspired me to write up some very general thoughts on the state of mainstream economics. Today, I believe, mainstream economics is completely incoherent. What do I mean by that? Well, basically if you are in the mainstream you can pretty much believe in whatever you want these days.
Mainstream economics today can be made to say anything. But in being able to do this it says nothing. All the new gimmicks that have been introduced into the mainstream — from asymmetric information to rational expectations — have rendered it a total free-for-all. So, some of the mainstream will tell you that fiscal stimulus will have zero effect on the economy (Ricardian equivalence) while others will tell you that it is the key to future prosperity. Many will fall somewhere in the middle, unable to articulate their actual beliefs in any concrete manner.
