Red circles indicate the estimated effect (average treatment effect on the treated). For all specifications, we report the contemporaneous effects while the event is unfolding ( t = 0) and effects for up to six weeks after the event occurred ( t = 6). Blue triangles indicate placebo estimates for up to six weeks before the event ( t = -6). Shaded area indicates pre-treatment time frame. The lines indicate the 95% bootstrapped confidence intervals. A coefficient greater than zero indicates that parties increased the weekly share of press releases dedicated to the category Environment. We report changes in percentage points. Overall shows the overall effect across all party-week observations ( n = 39,910). Green ( n = 4,912), Left ( n = 18,420), Right ( n = 15,350), Opposition ( n = 24,116) and Government ( n = 10,572) limit the analysis to parties with the respective party characteristics. Floods ( n = 39,910), storms ( n = 39,910), wildfires ( n = 39,910) and extreme temperatures ( n = 39,910) retain all observations but change the treatment definition to capture the effect of the respective event type in isolation.
