Data Improvement and Labor Economics
回顾了过去30年劳动经济学中数据使用的变化，包括更多论文使用数据、非公开数据和国际数据，并介绍了普林斯顿数据改进倡议的工作。
The expansion of available data for research has transformed empirical labor economics over the past generation. This paper briefly highlights some of the changes and describes a few examples of papers that illustrate the advances. It also documents the changing ways data have been used in the Journal of Labor Economics over the past 30 years, including a trend toward a higher fraction of papers using any data and, among those papers using any data, a higher fraction using nonpublic data, a higher fraction using international data, and more frequent use of multiple data sources. Finally, this paper describes work that came out of the recent Princeton Data Improvement Initiative--a program that considers and furthers improved data collection.
