Estimating the Narcotic Effect of Public Sector Impasse Procedures
比较两篇关于公共部门僵局程序麻醉效应的论文，指出工业关系研究中需要更好结合模型构建与检验、定量与定性数据以及简单与复杂统计检验。
This paper compares the Butler and Ehrenberg analysis of the narcotic effects of impasse procedures, presented in the precedingarticle, with the purposes, methods, and empirical results of the authors' earlier paper on the same subject.The authors use the differences in the two papers to argue that a need exists to achieve a better blending in industrial relations research of model building and testing, of quantitative and qualitative data, and of simple and complex statistical tests.The differences in results presented in the two papers are shown to reflect, in part, differences in the definition of the problems examined.These authors stress the importance of choosing statistical techniques that fit the theoretical and policy problems of interest to industrial relations researchers and practitioners, and the power gained from mixing qualitative and quantitative methods.
