Event-study estimates of the impact of DV laws on the probability of unmet need. Notes: Each time point represents two-year intervals to improve estimation. The graph shows the difference in the probability of unmet need between treatment and comparison countries. Time is centered at the last untreated group. Point estimates of the lag and lead terms are presented along with their 95% confidence intervals. The omitted base category is taken as 1 year prior to the reform, indicated by the solid vertical line. The pre-reform period shows no evidence of divergent pre-trends, and the post-reform period is suggestive of homogenous treatment effects over time
