[Excerpt] Cohn's study is based on an analysis of wage and strike data from French coal miners between 1890 and 1935. Using a statistical analysis of the relative impact of strike activity and market determinants on changes in coal miner wages over the 45-year period, as well as a more traditional historical review of primary union, government, and employer sources, Cohn comes to some rather interesting conclusions about the relationship between strike activity and wage outcomes.
