Using Alsace‐Moselle Local Laws to Build a Difference‐in‐Differences Estimation Strategy of the Employment Effects of the 35‐Hour Workweek Regulation in France
利用阿尔萨斯-摩泽尔地区因历史原因对35小时工作周执行较宽松的特点，通过双重差分法评估该制度对就业的影响，发现无显著差异，质疑其有效性。
France's 1998 implementation of the 35-hour workweek has been one of the greatest regulatory shocks on labor markets. Few studies evaluate the impact of this regulation because of a lack of identification strategies. For historical reasons due to the way Alsace-Moselle was returned to France in 1918, the implementation of France's 35-hour workweek was less stringent in that region than in the rest of the country, which is confirmed by double and triple differences. Yet it shows no significant difference in employment with the rest of France, which casts doubt on the effectiveness of this regulation. (c) 2009 by The University of Chicago.
