Wealth of Nations

When I read about this the other day, I meant to look into it, but now the World Bank's Private Sector Development Blog has a pretty comprehensive post about the institution's recent report on the world's countries' total wealth. Should I mention that Switzerland tops the ranking on wealth per capita (shouldn't that be caput, I always wonder) by quite some healthy margin? Since this is a pretty uncommon capital stock perspective, as opposed to the GNP's flow perspective, it definitely deserves some attention, although the measurement, or rather, estimation challenges will be formidable.
