Arthur Kroeber: Bear in a China Shop

Time and again, China has defied the skeptics who claimed its unique mixed model -- an ever-more market-driven economy dominated by an authoritarian Communist Party and behemoth state-owned enterprises -- could not possibly endure. Today, those voices are louder than ever. Michael Pettis, a professor at Peking University's Guanghua School of Management and one of the most persistent and well-regarded skeptics, predicted in March that China's economic growth rate "will average not much more than 3% annually over the rest of the decade." Barry Eichengreen, an economist at the University of California, Berkeley, warned last year that China is nearing a wall hit by many high-speed economies when growth slows or stops altogether -- the so-called "middle-income trap."
