Invisible Dog Walkers Invade Cobble Hill - Gothamist → gothamist.com

They beat me to the punch!

My fiancee and I have been going to the nearby park after 9pm to watch dogs run around. That’s when they’re allowed off leash. I joked that we should bring an invisible dog leash and pretend to let him loose.

Insurance premium price fixing.

I emailed this to Planet Money:

I’ve heard the argument that the heyday of the airline industry came in part because the government fixed ticket prices. As a result, airlines had nothing else to do but compete based on quality. Airline deregulation did away with all of that, and the general consensus is that this was a good thing — tickets became more affordable for all, airlines became masters at optimizing costs, routes, and providing variety.

That said, I’m intrigued with the idea of government fixing prices to force insurance companies to compete on quality. I’m free market enough to want insurance companies to compete, so I figure, why not a hybrid?

What if the government said something like “all insurance companies must offer a plan at $X/month that anybody can take” (where X is set low enough to expect most of the population to be able to afford it, perhaps a fixed % of CPI). It’s up to the insurance companies to say what exactly the plan covers.

It very well might be the case that no insurance company offers serious plans. But I suspect that the government could come up with *some* X that would be reasonably profitable for insurance companies. The government was going to do that work anyway in the form of a public option. The difference here is that the we let the free market dictate the actual benefits.

There’s a potential feedback loop here — if an insurance company offers a plan at X better than anybody else, more people will sign up for it, which should theoretically bring down the liability variance, making the plan more profitable, etc…

Is there an example, besides the airline industry, of price fixing leading to higher quality?

What is the cost of insuring your investments?

I had a conversation with a Schwab representative about what should happen to my investments if Schwab were to go under. I figured the answer would be one of two possibilities:

  1. You lose everything.
  2. You keep everything.

The answer is neither. According to this rep, the government insures up to $500k of your investments.

To make the discussion more concrete — imagine that you’ve got $1,000,000 (what an imagination!), and you put it all into a CD (not very imaginative). This is basically the safest investment you could possibly make short of stashing cash underneath your mattress.

If Schwab goes out of business, the government will insure that you still have $500,000. It’s unclear to me if they insure a $500k CD, or if they just hand you $500k in cash. Anyway, that’s unimportant.

My question is: what is the cost of insuring the rest of the $500k? In other words, how do I gain if Schwab craters?

One solution is to buy put options. If Schwab stock drops to near zero, you want to be able to sell it to someone at a higher price and buy it at the near zero price.

As of this writing, the last put option at a strike price of $7.50 expiring Jan 21, 2011 (let’s call it 1 year from now) sold for 40 cents. If you wanted to insure $500k, you’d have to buy about 667 of these contracts. Assuming that you’d be able to find counter parties for all those shares, this would cost you about $266.40, which is less than 0.02 percent of your portfolio per year. Or, roughly equivalent to Vanguard fees. Not bad.

Then again, I might be doing my math wrong. I’m not terribly familiar with options.

This is, for all practical purposes, a theoretical exercise. If Schwab were to crater, I fully expect that they would sell off their deposits to another bank. Schwab is also known to be a conservative and well capitalized bank.

But, if you are paranoid enough to get the options… make sure you buy them through a different brokerage.

Maybe the field of economics can redeem itself and start turning its tools on happiness. Maybe we’ve spent enough effort optimizing GDP, and we should optimize something else.

“It turns out that dentistry itself may not be as useful as Keynes believed: regular dental checkups are likely to give you no more than five extra teeth when you’re 75 – assuming you live that long. This is a modest and distant reward for a lifetime of being drilled.” —

Tim Harford — Article — The economics of bad breath

I don’t floss more than once or twice a week. It’s a hassle for me; my teeth are so jagged that I tear floss apart, and I have a permanent retainer, so it requires three lengths plus a plastic threader to finish.

Anyway, maybe it’s not all that important? At least now I can claim I’m acting rationally.

“Another policy states that a foreign company may not operate an online game on its own in China; it has to have a Chinese partner and share its revenues with that partner, Cosmas Hanson said. Chinese game companies that operate in the U.S. have no such restriction.” —

How accurate are BAM Investor’s stock predictions? Check Twitter | VentureBeat → digital.venturebeat.com

Hm, sounds like snakeoil to me. Why would a company that produces real trading insights give this information to hedge funds? Why not trade it themselves?

My gut reaction: because the cost of their service is greater than the expected gain from trading their predictions.

S.E.C. Seeks to Ban Computerized ‘Flash Trading’ - NYTimes.com → nytimes.com

In a previous post, I argued that it was incorrect think that everyday investors could not take advantage of automated markets if they chose.

Regarding flash orders, it’s important to understand that all serious retail brokerage firms have access to all flash orders on all electronic markets, thereby eliminating supposed information advantage. The real reason flash orders exist is to avoid additional routing fees associated with sending an order to the general market.

It sounds like at least the Times is beginning to understand that the information imbalance isn’t as significant as earlier reporting made it out to be:

“While anyone can gain access to flash orders for a fee, only very powerful computers can process and act on the information.”

So, now they’re picking on the “very powerful computers” straw man? At my previous automated trading jobs at two different firms, we used nothing but commodity server hardware. A $900 box from Dell can process over 9 million instructions in the 5 milliseconds it takes a flash order to fill. (To put it in perspective, $900 is the cost of owning an iPhone for 1 year)

To call this a “very powerful computer” is not untrue, however it is misleading.

Peering into the Black Box - WSJ.com → online.wsj.com

Of course I’m biased, but I still don’t understand this outcry that the small investor doesn’t have access to automated trading. That’s nonsense. They have access in two ways:

  1. Use an electronic brokerage firm (nearly all are) to place trades — the firm employs programmers to intelligently trade at prices better than what the “small investor” asked. Whether or not they pass those profits on is brokerage dependent (I occasionally get price improvements through Schwab).
  2. Open up an automated trading account. They will give you the APIs and the fast access to get your own flash orders.

That said — taking on option #2 requires three things: a quantitative trading strategy, programming ability, and a couple hundred grand of capital.

Lamenting that the “small investor” can’t get those things is like me complaining that I can’t beat FedEx’s shipping rates. That’s absurd. I would have great rates if I had: the volume, the operational knowledge to run a shipping company, and huge amounts of capital.
