Will inflation have a disastrous impact on the Chinese economy? What risks are brewing behind the booming real estate and stock markets? Have bubbles already occurred in the Chinese economy? From his office in Guohong Building, Beijing, Dr. Fan Gang gave his views on these questions in an exclusive interview with China Economist.展开更多

Reports in a book on randomized trials by Mosteller and Boruch are used as a benchmark. The initiatives have been driven heavily by recent governmental emphasis on "evidence based policy" in education, criminology, welfare and other sectors. This policy has been backed, in the US at least, by substantial investments in mounting randomized controlled trials to evaluate curriculum packages and programs in grades K-12, crime prevention programs, welfare, and other work. Accelerated growth in randomized trials has entailed cross discipline pre-doctoral and post-doctoral institutes and graduate education programs aimed at enhancing the quality in trial design, execution, and analysis of results. Specific illustrations of graduate education in this area of statistics are taken mainly from experience at the University of Pennsylvania's Graduate School of Education and selected other institutions.展开更多
