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.

Andrew Martin has an article in The New York Times on the dynamics of the debit card industry. I don’t have any expert knowledge to add, but here’s the summary: Visa has been increasing its market share by increasing the prices it charges to merchants; it takes those higher transaction fees and passes some of them on to banks that issue Visa debit cards, giving them an incentive to promote Visa debit cards over other forms of debit cards. Not only that, there are different fees on debit cards depending on whether you use them like a credit card (signing for them) or like an ATM card (entering a PIN). Signing costs the merchant more, so the banks and Visa give you incentives to sign instead of using a PIN. The end result is higher costs for merchants, who pass them on to you.

Financial commentators use metaphors* all the time. Derivatives are “financial weapons of mass destruction,” for example. Actually, people use metaphors all the time. But what is the substantive content of a metaphor? More technically, if A is (like) B, then why should we believe that A has some attribute that B has?

I’ve been meaning to write about this for a while, but then Robert Shiller handed me a perfect example in the Financial Times, in his “defense of financial innovation:”

“The advance of civilisation has brought immense new complexity to the devices we use every day. A century ago, homes were little more than roofs, walls and floors. Now they have a variety of complex electronic devices, including automatic on-off lighting, communications and data processing devices. People do not need to understand the complexity of these devices, which have been engineered to be simple to operate.

“Financial markets have in some ways shared in this growth in complexity, with electronic databases and trading systems. But the actual financial products have not advanced as much. We are still mostly investing in plain vanilla products such as shares in corporations or ordinary nominal bonds, products that have not changed fundamentally in centuries.

“Why have financial products remained mostly so simple? I believe the problem is trust. People are much more likely to buy some new elec­tronic device such as a laptop than a sophisticated new financial product. People are more worried about hazards of financial products or the integrity of those who offer them.”
