The author of this quote claims that asymetric information is “proof that free markets don’t work.” It seems to me that there will always be some sort of asymetric information in any trade, but that doesn’t mean that free market capitalism fails. I’m just not sure what the true counter argument is for this. quote:
"I have not been a great fan of the theory of rational expectations – the belief in cold, rational, c"alculating
homo sapiens; indeed, I believe it to be the greatest-ever failure of economic theory, which goes a long way toward
explaining how completely useless economists were at warning us of the approaching crisis (with a half handful of
honorable exceptions). But it would be a better world if their false assumptions were actually accurate ones: if only
information flowed freely, were processed efficiently, and were available equally on both sides of every transaction,
we would indeed live in a more efficient and probably better world. The problem that information is asymmetrical
in the financial business is a serious one. One side of the transaction, say an institutional pension fund, is often at the
mercy of the other, say the prop desk of a talented and mercilessly profit-oriented investment bank."
This is one of those arguments that can’t be responded too because it is so arbitrary. I can’t categorize it as right or wrong because alone I don’t know what it is saying or how it is supposed to relate to the rest of my knowledge.
So what if some people know more about a deal than others? What does that have to do with markets?
Anyways, the term “information” in the context of economics is not meant to be used in the sense of what two particular people understand about a particular kind of deal. Information is meant to be used as a way of describing how markets coordinate resources with desire. So an example of information would be an interest rate, which coordinates consumption over time. All prices are information also, they tell us about supply and demand among other things.
The problem he is pointing out is “we are at the mercy of those who are experts in their field, they might rip us off”. First of all, this I believe is true for all systems and all industries. This is a problem I have been working on myself. My doctor might be a quack, how do I know,am not a doctor? My broker might be ripping me off, how would I know to trust him or not, I wouldn’t know enough about finances to tell if I was being ripped off.
There are ways of getting around this, but no system is going to fix that.
