Is the Chinese growth miracle built to last?

Is the Chinese growth miracle – a remarkably high growth rate sustained for over two decades – likely to persist or are the seeds of its eventual demise contained in the policies that have boosted growth? For all its presumed flaws, the particular approach to macroeconomic and structural policies that has been adopted by the Chinese government has helped to deliver high productivity and output growth, along with a reasonable degree of macroeconomic stability. There comes a point, however, when the policy distortions needed to maintain this approach could generate imbalances, impose potentially large welfare costs, and themselves become a source of instability.The traditional risks faced by emerging market economies, especially those related to having an open capital account, do not loom large in the case of China. In the process of securing protection against external risks, however, Chinese policymakers may have increased the risks of internal instability. There are a number of factors that could trigger unfavorable economic dynamics that, even if they don't rise to the level of a crisis, could have serious adverse repercussions on growth and welfare. The flexibility and potency of macroeconomic tools to deal with such negative shocks is constrained by the panoply of policies that has supported growth so far.     

PENNIES FROM EBAY: THE DETERMINANTS OF PRICE IN ONLINE AUCTIONS*

This paper presents an exploratory analysis of the determinants of prices in online auctions for collectible United States one‐cent coins at the eBay web site. Starting with an initial data set of 20,000 auctions, we perform regression analysis on a restricted sample of 461 coins for which we obtained estimates of book value. We have three major findings. First, a seller's feedback ratings, reported by other eBay users, have a measurable effect on her auction prices. Negative feedback ratings have a much greater effect than positive feedback ratings do. Second, minimum bids and reserve prices have positive effects on the final auction price. In particular, minimum bids appear only to have a significant effect when they are binding on a single bidder, as predicted by theory. Third, when a seller chooses to have her auction last for a longer period of days, this significantly increases the auction price on average.
