Someone needs to clamp down with some hardline Ti rules. What Brown (although ILI and thus not Beta) in banning short-selling of stock, may have been bad for the markets, but in the long run, it was a very wise thing to do, and actually helped the markets.
This illustrates the point that not all Gammas can keep things flowing smoothly, and not always is the economy a self-regulatory body. In my eyes, if a company like Lehman Brothers goes bust, the government should not step into to pump public funds into it. It's daylight robbery, and completely contrary to the idea of the liberal economy we condone, whereby if a corporation can't stand up by itself, it should be left to die.
Nonetheless, for the most part, Gammas and economy are a nice thing to have in this world.
