Six Decades of Top Economics Publishing: Who and How?
分析了1960年代至2010年代三大顶级经济学期刊中所有长篇文章的数据，揭示了合著模式、年龄结构和研究方法的变化趋势，对经济学研究者了解出版动态有参考价值。
Presenting data on all full-length articles in the three top general economics journals for one year in each decade 1960s–2010s, I analyze changes in patterns of coauthorship, age structure and methodology, and their possible causes. The distribution of number of authors has shifted steadily rightward. In the last two decades, the fraction of older authors has almost quadrupled. Top journals are publishing many fewer papers that represent pure theory, regardless of subfield, somewhat less empirical work based on publicly available data sets, and many more empirical studies based on data collected by the author(s) or on laboratory or field experiments.
