QotD: Trade is THE solution to poverty

Trade is THE solution to poverty. Throw in international labor mobility, and we're well on the way to remedying any of the problems that money can fix — like controlling infectious diseases, providing electricity, clean water and sanitation, feeding people, educating women, and so forth. Or at least that's what Kym Anderson, an economics professor at the University of Adelaide in Australia more or less asserted in his presentation on trade and migration on the third day of the Copenhagen Consensus 2008 Conference.

Anderson looked at a number of econometric modeling scenarios and calculated the cost and benefits that would obtain from full trade liberalization under realistic assumptions derived from the current World Trade Organization's Doha Development Agenda negotiations. Anderson estimated that liberalization of global merchandise trade would mean an annual increase of $287 billion per year in global GDP, of which $86 billion would go to developing countries. This compares very nicely with the $104 billion in development assistance that the governments of industrialized countries gave to developing countries in 2006.

In other calculations, Anderson found that the long term effects of trade liberalization would be that global income in 2098 would be up to 10% greater than it otherwise would have been. The associated net present values from freer trade range from $50 trillion to $424 trillion. Consider that in 2007, total gross world product was $53 trillion. In other words, both the immediate and long-term benefits from free trade are enormous. Anderson reports benefit cost ratios ranging from 269:1 to 1121:1.
