Abstract
How do social movement organisations achieve the societal changes they seek? Scholars commonly argue that organisations require the
media's attention to diffuse their concerns among the public. However, the field continues to struggle with causally
linking organisations to their outcomes and empirically uncovering the underlying processes.
Furthermore, various conceptualisations of social movement and public opinion, and the focus of the literature on the US
complicate testing and developing theory. I address these limitations by analysing the dynamic interactions between the Swiss
environmental movement, the public, and various factors capturing opinion leadership by the elite from 1974 to 2020. Relying on original and secondary data, I leverage 100 survey questions on environmental issues, which I collate
utilising the dyad ratios algorithm and hierarchical Item Response Theory. These time series are the first without
interpolated values and advance existing measures for the years 1974 to 1993.
To this data, I apply vector autoregression models, Granger causality tests, and the impulse response function, and
decompose the forecast errors' variance. I find that the national government's attention to environmental issues encouraged
the national parliament to engage with these issues, which spurred newspaper coverage of collective action events.
These discursive shifts around environmental protection strengthened the public's preference for environmental protection,
consistently resulting in a higher vote share for the Green Party and the Green Liberal Party.
