In Honor of David Card: Winner of the John Bates Clark Medal
介绍约翰·贝茨·克拉克奖得主大卫·卡德对经济学和新实证主义的贡献，他通过创造性且严谨的实证研究，利用大规模数据集和合理的外生变量变化来揭示行为反应，对劳动经济学及整体经济理解有重要启示。
This paper describes the contribution of David Card, winner of the John Bates Clark Medal, to economics and the new empiricism that has become such an important part of the profession. Card's forte is creative and careful empirical scholarship that exploits modern computerized data sets with thousands or hundreds of thousands of observations and that uses plausible sources of exogenous change in key variables to determine behavioral responses. The work has the flavor of a laboratory scientist reporting an experiment. It has illuminated virtually all areas of labor economics and has implications for the understanding of the economy writ large.
