In the United States there are only two exceptions: banks have to report deposits they suspect to be related to either terrorism or drug trafficking. But if your funds derive from trafficking women and children for sexual exploitation, for example, or from illegal arms trafficking or any other illegal activity, then banks in the US are legally free to accept your money and are not required to report your deposit to the authorities.

I see a violation of human rights not in the mere fact that people don't have enough to eat and that they are very vulnerable, but I see it in the fact that the economic institutional order of the world is associated with this very persistent poverty and that different institutional arrangements at the supranational level could stop and even reverse the slide towards ever-greater income disparities.

Car prices play a large role in calculating PPPs even while they play no role whatsoever in the consumption or consumption needs of the poor. And the prices of rice, bread and beans play a small role in calculating PPPs even though they play a huge role in meeting the consumption needs of the poor. So the World Bank's method of comparing and converting everything at general purchasing power parities into US dollars is highly distorting within an exercise whose purpose it is to determine whether households are or are not capable of meeting their basic consumption needs.

The collective shortfall of the 3.08 billion people (47 percent of world population) who, in 2005, lived below $2.50 per day was $507 billion per annum, which indeed comes to about two-thirds of the present US military budget. This gives us a rough sense of how much the eradication of poverty would cost.

It is irrational to charge high prices for socially valuable innovations as this guarantees that they will be underutilized. It is much better to sell them at cost and then to reward the innovator in some other way. This is not always possible, because in some cases the value of an innovation is in the eye of the beholder; it's very difficult to value how much a new Madonna song is worth, for example. But in the case of medicines, green technologies and seeds in agriculture, such an alternative reward mechanism is fairly straightforward.

Each powerful player, or coalition of players, will make concessions in areas where it has relatively less at stake in exchange for other such players making reciprocal concessions in other areas where it has relatively more at stake. Such trades are collectively rational insofar as they get each of the powerful players more of what it wants. But such trades are also dangerous because the whole international rule-system will become incoherent and therefore vulnerable to crises that will continue to become increasingly severe.

Often vastly more important, international agreements are not routinely published in draft form or publicly debated, and civil society organizations and ordinary citizens often learn of important global institutional design decisions only after they have already been finalized and adopted. The only reliable way to be kept informed and to exert timely influence is by lobbying and paying the politicians and their negotiators.
