I don't quite understand this argument. I certainly agree that front-running of the kind you describe would make someone a lot of money. This is one of the reasons that being a NYSE specialist was hugely profitable back in the pre-elec

Pending transactions are never public. Everyone sees the execution on that exchange, but they don't know whether or not some additional portion is being routed to another exchange. One situation that people often _mistake_ for this typ

You're absolutely right that there's some risk involved in order-book spoofing, but the intent is the same as the examples I gave. In practice, the spoofers reduce their risk by doing things like placing a tiny order first to see

The real-world equivalent would be setting up a website that advertises some item for sale at a low price, and then getting some other seller to beat that non-existent price so you can buy it cheaply. Or, you're a realtor negotiating w

In my (parents') experience, the problem with the internet connections available in rural areas is not the speed, but monthly data caps. You can get satellite internet service that is fast enough to use Netflix, etc., but you'll h

Yikes. I meant that last sentence with a bit of tongue-in-cheek. I certainly don't mean it's a _bad_ thing for parents to pay to raise their children. But surely you would prefer to be born owing some extra taxes, rather than neve

The idea of positive externalities (also called "external benefits") is definitely mainstream economics. Deciding a priori what the "right" population level for the United States is seems philosophical to me. There are p

The economic argument would be that some of the benefits of creating new people are captured by the rest of society, not just the parents, and so to maximize efficiency, some of the costs should also be borne by society. Interestingly, this

From the article: "experts say that the vast majority of mosquito nets are used exactly the way they were intended". There's also good evidence that they work: http://www.givewell.org/international/techni

A one-to-one means-tested top-up means that the effective tax rate on all income below the guaranteed level is 100%. That is pretty obviously a terrible idea.

One example of this happening: Perlman's proof of the Poincare conjecture was posted on the arXiv first ( http://arxiv.org/abs/math/0211159 ). In fact, I don't think it was ever formally published.

It seems like the issue is that regulated utilities are not really private companies, though we like to pretend they are. The segment of Verizon that provides voice service is effectively a government agency, and if they make money, the res

RIP-relative addressing is _possible_ for the lea instruction, but not mandatory. Also inc ax, etc. seem to assemble just fine in 64-bit mode, albeit with a prefix (0x66) and a different opcode (0xFF)

True. If you can't tell how "hard-working" someone is from an interview, you might end up using "willing to work with less vacation" as a crude filter. This is probably part of the answer to the whole question. In a

I don't disagree that bad decisions are made all of the time, but the questions is how the same bad decision can be made everywhere in a competitive marketplace. You've given a couple of good examples where the answer is governmen

I don't think I see a single negative comment here about long vacations, so allow me to play devil's advocate. (These questions don't necessarily reflect my own opinions.) 1. If this is such a free lunch (employees are both h

Unfortunately, taxing gross income instead of profits simply won't work for corporate taxes. The cost of doing business varies wildly between industry, or even between different business models in the same industry. You'd end up p

There's a good case to be made that learning job skills is not the main benefit of going to college: http://www.cato-unbound.org/2008/10/10/bryan-caplan/murray-n...
