I’ve had Robert Litan’s recent paper defending most financial innovation (the web page doesn’t tell you much; you need to grab the PDF) on my to-do list for a while now. I wasn’t looking forward to writing about it, since I’m a bit tired of the subject, and I don’t think I have much more to say. So thankfully Mike Konczal beat me to it, in a two-part series. Part I is really brilliant, and has not one but two insights. The first (to simplify) is that we generally think of innovation in products as making them simply better on all dimensions. We don’t realize that, with most new financial products, we are just getting to a new point on the risk-reward spectrum that wasn’t there before. Now, it might be good for the economy as a whole for that new point to exist. But as consumers, we don’t realize that the good properties of a new financial product are almost invariably counterbalanced by some bad properties.
The second insight is that real, good financial innovation does not look like a new product; it looks like a new way of dealing with an existing product. Konczal’s example is TRACE, a recent system for increasing transparency in the market for corporate bonds (you’ll have to read his post for a more complete description). The effect has largely been to make pricing more transparent and reduce spreads, which is good for investors. More broadly, as Felix Salmon said somewhere (probably many times), financial innovation should show up as lower prices for all the bread-and-butter financial products–equity and debt underwriting, interest rate swaps, etc.–not has higher profit margins for dealers.
Konczal’s Part II asks some more general questions about Litan’s results. I have some different questions.
