Behind the housing bubble, there was a bet that home prices would continue to rise and home owners would continue to make payments. When home values stopped rising and home owners stopped paying, the deck of cards collapsed.
China has been able to grow so rapidly by shifting large numbers of underemployed workers from agriculture to manufacturing. It has an extraordinarily high investment rate, on the order of 45% of GDP. And it has stimulated export demand by maintaining what is, by any measure, an undervalued currency.But, in response to foreign and domestic pressure, China will have to rebalance its economy, placing less weight on manufacturing and exports and more on services and domestic spending. At some point Chinese workers will start demanding higher wages and shorter workweeks. More consumption will mean less investment. All of this implies slower growth...In recent work, Kwanho Shin of Korea University and I studied 39 episodes in which fast-growing economies with per capita incomes of at least $10,000 experienced sharp and persistent economic slowdowns. We found that fast-growing economies slow when their per capita incomes reach $16,500, measured in 2005 US prices. Were China to continue growing by 10% per year, it would breach this threshold just three years from now, in 2014.
