政策評估Policy Evaluation

政策上路之後，真正發生了什麼？What actually happened after the policy took effect?

我們以中斷時間序列、差異中之差異等因果推論方法，評估 COVID-19 防疫措施、疫苗與人流對疫情與醫療照護的影響，並將方法延伸到生育相關政策。 With interrupted time series, difference-in-differences and other causal inference designs, we evaluate COVID-19 measures, vaccination and mobility, and extend these methods to reproductive health policy.
