Wholesalers have agreements with retail brokers to provide a certain level of "execution quality", and that's what they compete on (fiercely). If they pushed the price around on one order, they'd have to make it up on so

Yes, the typical Chinese factory worker (who would not even be particularly poor by Chinese standards) is quite a bit poorer than the typical displaced American factory worker, so there should be a strong presumption against transferring we

Do you think that by using tariffs for political pressure, we can force China to raise their standard of living to developed-country levels? Otherwise, this just amounts to a transfer from the Chinese poor to the American poor, which seems

US industrial output is way up over the past few decades; it's just industrial employment that's way down.

That seems like a strange perspective to me. All of the theoretical justification for passive investing (you get the average return without the fees, maximum diversification, etc.) implies that you'll get the best result from holding e

If you want to be sure of positive expected value, just pick randomly, with probability proportional to market cap. That gives the same expected value as an index fund, with much higher variance.

An alternative framing: if we doubled the size of the income tax, we could pay each person $4300 / year.

That would be contrary to how labor markets work in other income ranges: e.g., if someone gets a big inheritance, you'd expect them to be more likely to reduce their work hours than increase them. Empirically, it seems like the same is

Logarithmic utility of money implies that the last X% of your income is worth the same amount of utility, regardless of what your income is: log(x) - log[(1 - r)x] = log(x) - log(1 - r) - log(x) = -log(1 - r). But "does the same harm t

According to this paper ( http://arxiv.org/pdf/1601.02184v1.pdf ), the entry for n=56 should also be one. Apparently, these values come from a computer-assisted calculation from 1990, and the error wasn't discovered

I think the GP is referring to differences in standard deviation, not mean, which causes the larger-deviation population to dominate at both the left and right tails.

Another re-phrase: how can we detect that space has stretched out if all of our rulers also get stretched by exactly the same amount? The answer is that we have a ruler that doesn't get stretched in this way: light. The speed of ligh

I disagree. I would call this a proof but not a derivation. In other words, each step follows logically from the previous ones, even if there's no way that you would discover the final equations this way if you didn't already know

A negative income tax is basically equivalent to a basic income funded with a progressive income tax. No matter how you pay for it, some people are going to pay more in taxes than they get from the basic income, and some will pay less. For
