This article reanalyzes the data of a previous study on the policy impact of antinuclear, ecology, and peace movements in three countries with the aim of replicating its findings. Our goal is to see whether using a different analytical technique will yield similar results. The previous study used a regression approach to time-series analysis. Here, we use qualitative comparative analysis (QCA) to analyze the previous study's data. Specifically, we test the two main hypotheses based on the joint-effect model of social movement outcomes: (1) that the policy impact of social movements is conditioned by the presence of powerful allies within the institutional arenas, by the presence of a favorable public opinion, and/or by both factors simultaneously; and (2) that social movements are more likely to have policy impacts when they address issues and policy domains of low saliency. In addition, we compare the policy impact of social movements across countries. Our analysis confirms to a large extent the findings of the earlier time-series analysis, namely, the strong explanatory power of the joint- effect model of social movement outcomes and the varying impact of different movements on public policy.
