China's accession to the World Trade Organization (WTO) was a watershed event for both China and the WTO. After 30 years of effective isolation from the world economy, and close to a quarter century of autonomous reforms, China joined the legal framework of the world trading system. In doing so...

The gravity model is now widely used for policy analysis and hypothesis testing, but different estimators give sharply different parameter estimates and popular estimators are likely biased because dependent variables are limited-dependent, error variances are nonconstant and missing data...
