Market making is not really like directional trading. When a market-maker trades, the price is very likely to move against them afterwards. To be profitable, all that they need is for the price to move against them by slightly less than the

The second order problem is how to select which "experts" to believe. In my opinion, Hunsader sees conspiracies where none exist and interprets all unusual or hard-to-explain behavior as evidence for his existing beliefs. (Not to

Not in the United States. Obamacare made most of this type of thing illegal: only geography, age, and tobacco use are allowable variables, and there are caps on the size of the variation in price.

The best suggestion I've seen is 1¢ for the 141st character, 2¢ for the 142nd, 4¢ for the 143rd, etc. Going slightly over 140 costs a trivial amount, but it would be stupidly expensive to tweet anything really long. EDIT: I found where

But this has nothing to do with notional value. The world wouldn't be safer if we rewrote all contracts saying "1% on a notional amount of $100M" with "1M% on a notional amount of $100".

I'm sympathetic to your ideas, but you're really overstating your case here. Redistributing income is probably the primary activity of governments in rich countries today. Even in the US, transfer payments are about 14% of GDP: h

Okay, you've convinced me that the distinction between positive and negative rights is not airtight. I still think it's a useful categorization, though, even if the boundaries are little fuzzy.
