Figure 4.
The line plots represent coefficients measured across periods from negative 7 to positive 4 relative to an event. In the first plot labelled (a), the vertical axis shows coefficients ranging from negative 0.04 to 0.04, and the line fluctuates slightly around zero, with small upward movement after the event at period zero. In the second plot labelled (b), coefficients range from negative 1 to positive 1. The line shows a similar pattern but with larger amplitude, indicating an increase after period zero and higher stability in later periods. Each data point includes vertical dashed error bars that mark confidence intervals. The dashed vertical line at zero separates pre-event and post-event intervals, highlighting the change trend after the event occurrence.Results of the common trend test
