Is Behavioral Economics Dead? Should It Be?


  Wow....Pretty harsh, from an insider of Behavioral Economics

But also this, rather embarrassing and even ironic since the study was "about" honesty... 

To be fair, Nassim Taleb and a few others have been very critical for a long time. But the collapse of house of behavioral cards is still pretty dramatic. 

Taleb's argument is very plausible: If human behaviors are evolved, then the existence of certain patterns cannot actually be "irrational," though it may be atavistic).

Transaction Costs in Everything

 As any reader of KPC knows, we often credit Tyler Cowen ("LeBron") for his occasional, but always insightful, series of posts on "Markets in Everything.

I have been accused of finding "Transaction Costs in Everything," so I might as well own that. My plan is to post at least weekly on this, and so have a collection of applications.

Prompted in part by this (accurate) comment from the LMM:


An example, then.

We had a piece of furniture, a bed frame actually, that we were going to throw away. But the LMM wondered if someone might want it. So she posted a "free, take it!" listing on NextDoor

Within half an hour, two people had said they wanted it. Instead of sending it to the dump, it was now actually going to be used by someone who needed it.

I was very excited by this, and of course launched off into my rambling: "Do you know WHY this happened, why someone will now use something we were going to throw away?"

LMM: "Well, it's not because of you...." (It is barely possible, as all my coauthors know, that I sometimes take credit for things I did not actually do, I'll admit that. So her response was not out of line...) 

MM: "Quite so. No, the answer is...." (LMM is staring at me, already mildly disgusted at the coming lengthy disquisition)

"transaction costs! Or rather the reduction in transaction costs. The small value of the thing we are giving away, an old bed frame, limits the amount of effort justified by finding someone who needs it. YOU would not have gone door to door, knocking and asking 'need a bed frame? need a bed frame?'  But you didn't have to. Because the transaction costs on both sides, announcing the availability of the free thing and finding a willing taker for the free thing, were reduced by a platform, the bed frame went to a higher valued use instead of the dump! The online platform helped us make better use for a bed platform! It's a triumph of cooperation in the new sharing economy!"

She's got that thousand yard stare at this point.

I continue, very excited: "Such an important, general insight! Why, I bet they'll put 'He's Reducing Transaction Costs in Heaven' on my tombstone!"

LMM (sotto voce): "Soon, I hope."
