Summary: Pre and Post Regulation Metrics

We present the pre and post-regulation summary statistics below. Specifically, we present the average monthly values for the regulated molecules in the pre-regulation (50 months prior to regulation) and post-regulation (12 months post-regulation) periods. From Table 2, we find that, in the year after regulation compared with the period before regulation, sales of regulated SKUs increase by around 11 million units on average. Prima-facie, one might misinterpret this increase as evidence that the regulation is working. However, there may be trends and seasonality in the data that need to be accounted for in our analysis.
