Normative theories of democracy agree that public demand should be the main guide in policymaking. But positive theories and related empirical research disagree about the extent to which this holds true in reality. We address this debate with an empirical focus on climate change policy. Specifically, we are interested in whether observable variation in public demand for climate change mitigation can help explain variation in adopted national climate policies. Using our own data to approximate public demand, we estimate the responsiveness of policymakers to changes in public demand in six OECD countries from 1995 to 2010. We find that policymakers are responsive and react in predicted ways to variation in our opinion component of measured public demand, rather than to the mere salience of the climate issue. The effect of issue salience is strongest in combination with our opinion measure as this creates a scope for action. The results underscore the importance and usefulness of our concept and empirical measures for public demand, as well as of our disaggregated analysis of climate policy outputs in this area.

What factors influence agenda setting behavior in state legislatures in the United States? Using the localized effects of climate change, we examine whether notable changes in temperature can raise the salience of the issue, thus encouraging a legislative response. To evaluate the behavior of individual legislators around climate policy, we utilize an original data set that includes geographic mapping of climate anomalies at the state legislative district level and incorporates individual, chamber, district, and state characteristics to predict climate bill sponsorship. Using a multilevel model that estimates climate change bill sponsorship among 25,000 legislators from 2011 to 2015, we find a robust relationship between temperature anomalies and bill sponsorship for Democratic members of state legislators while Republicans are unresponsive to such factors. Our data and methodological approach allow us to examine legislative action on climate change beyond final policy passage and offers an opportunity to understand the motivations behind climate innovation in the American states.

Does party government moderate the responsiveness of public policy to public opinion? Analysing a new dataset, we examine whether the ability of governments to respond to the public on 306 specific policy issues in Denmark, Germany and the UK is affected by the extent of coalition conflict and by the fit of the considered policy changes with the government preferences. We find a systematic but relatively weak positive impact of public support on the likelihood and speed of policy change. Contrary to expectations, a higher number of coalition partners are not associated with fewer policy changes nor with weaker responsiveness to public opinion. We also find no evidence that responsiveness to public opinion is necessarily weaker for policy changes that go against the preferences of the government. Rather, it appears that public and government support for policy change are substitute resources.
