Unit 4 Macro: Growth in the Emerging Economies - Can It last?

I am linking here to a recent (October 2012) lecture and discussion at Gresham College in London. The three eminent speakers look at the limits to world economic growth from an environmental and economic perspective. Will inflation caused by rising primary product prices be likely to be the key constraint on economic growth? Douglas McWilliams, Thras Moraitis and Mike McWilliams consider whether this constraint will bite at a sufficiently slow rate for the impact of the extra growth in emerging economies to mean that the West will have to grow more slowly.
