Chapter 5 takes a deep dive into the history of US agrochemical regulation in order to show that innovative companies were a major force behind the adoption of institutions that required the precautionary reevaluation of existing products, in opposition to generic producers who stood to lose out from such institutions. Using an original dataset that tracks changes to US agrochemical regulations over a two decade period, the chapter then provides evidence that in the wake of these institutions’ implementation, regulations have become stricter on older, less profitable products over time for reasons that cannot be attributed to health, safety, or obsolescence alone. In addition, the chapter provides evidence that the mechanism behind this outcome is not the political power of producers but rather their ability to leverage their information advantages under a regulatory regime in which products are subject to precautionary reevaluations.
