摘要:
      We examine whether and how external entry threats affect incumbents’ timing of pipeline product launches. Using Paragraph IV filings as generic-entry threats in the pharmaceutical industry, we find that challenged firms increase launches in the same therapeutic category, particularly novel drugs, shortly after a challenge. We strengthen the causal interpretation of these findings by exploiting an FDA regulation governing the earliest date when a Paragraph IV filing may occur. Entry threats reduce the expected sales of existing products, alleviating internal cannibalization concerns and accelerating the commercialization of previously approved pipeline products. Consistent with this mechanism, these launches erode challenged-product sales before generic entry occurs.
