Keep the Casinos Open
by Clifford S. Asness, Ph.D.
Preliminary version Last updated: April 26, 2010
In the storm of politician and pundit pique over financial regulatory reform, brought to a crescendo by conveniently-timed SEC charges against Goldman Sachs1, one refrain is repeated again and again in different forms. Paraphrasing a few:
• Wall Street is just a casino.
• Over-the-Counter derivatives like the Goldman Sachs’ CDOs are just “side bets” and should be banned, or at the very least we should regulate the bejesus out of them.
• These “bets” aren’t “real investments”.
• We should not let people “gamble” in this manner.
However ubiquitous, and now verging on the conventional wisdom, this is still just silly talk.
First, almost all derivatives are side bets. Even the exchange-traded, clearinghouse-blessed plain vanilla ones that the love-to-regulate crowd supports are still side bets. The simplest S&P 500 futures contract is a bet between the long investor and the short investor that is settled up without any stocks changing hands. Even contracts that, in theory, have physical delivery at their end almost never do, and even if they did are still a side bet between the long party and the short party. So, unless you’re planning to ban all derivatives, including these plain vanilla exchange-traded clearing-housed beauties, please don’t complain about side bets and casinos.2, 3
OK, now why are these side bets good for the world? Well, first, I don’t think I need to prove that. To “ban” something (a word statists really love), you need to show it does a lot of harm to those that are not a party to the transaction. Otherwise, again, be quiet and let free people transact (including betting) with each other as they see fit. But, luckily, I don’t need to rely on just my fellow Americans’ love of liberty here. These side bets are indeed generally good for the world.4, 5
This is all fairly standard economics so I won’t spend much time on it. Any time you have a transaction, including a side bet, which both sides enter into voluntarily, both sides must think they are being made better off. In the case where one side is a speculator and the other a hedger (or better, two offsetting hedgers) both can be made better off before and after the fact. The speculator, by making money, the hedger by reducing a risk he feared (e.g., if you buy fire insurance on your home you are not made worse off by your home not burning down). The tough case seems to be speculator-on-speculator side bets. In this case somebody will win and somebody will lose. First, I appeal again for the rights of free people to put their money where their opinions lie. Just because somebody will be wrong doesn’t reduce this right. But, second, this activity still makes society itself better off. If these “side bets” encourage more research, more time and energy, into figuring out whether the current price is too high or too low, they themselves can make prices more accurate.
Consider of course the case of John Paulson and the now infamous Goldman Abacus deal. Now imagine that instead of just John Paulson and only a few others, many people realized how ugly the real estate bubble was going to be, and realized it a few years earlier than when it was actually experienced. If they all tried to put on “side bets” that real estate would fall (and mortgages would default), they would have moved prices. They would have had to entice people to take the other side. The way this enticement works in a free market is by prices changing. In other words, if more people tried to do this earlier, real estate prices never would’ve gotten so high, and mortgage yields never so low. Put simply, a more vigorous, more liquid, more active market for “side bets” like John Paulson’s would likely have made the real estate / credit bubble a less, not more, dangerous event.
Consider the recommendations of Professor Robert Shiller, famed for predicting both the technology stock and real estate bubbles. Shiller has long advocated a futures market on economic news. These derivatives would give us the ability to bet on how strong GDP will be, how high or low unemployment comes out, whether inflation is climbing back, etc. Furthermore, every one of these is a “side bet”. He doesn’t advocate these side bets as he cruelly wants to feed people’s gambling obsessions, or wants to create a new vehicle on which Wall Street can charge commissions. He advocates for these contracts because he knows that legitimate hedgers and speculators, facing economic risk themselves and wanting to reduce it (hedgers), or holding economic opinions and wishing to profit from them if correct (speculators), will use the contracts to make their worlds, and the World, a better place. Risk would be reduced for those who wish it, and through the research of speculators we would gain valuable insight into where the economy is heading (I promise no forecast will be as good as the net of those betting their own money). The “side bets” Shiller advocates here are worthwhile, but no more so than “side bets” on the state of the real estate and mortgage world back in 2007. And they are all worthwhile for the same reasons.
