- 요약This dissertation consists of two essays, a primary and a supplementary, on the economics of pharmaceutical line extensions. The FDA grants a three-year market exclusivity period for reformulated versions of existing drugs, known as line extensions, upon their approval. This policy can incentivize manufacturers to delay the launch of improved drugs until the original formulation's patent nears expiration, depriving patients of earlier access to better treatments. Chapter 1 considers a more detailed structural approach that captures the manufacturer's dynamic problem on when to introduce a line extension and how they should price their products, given the current policy. I develop a dynamic model to analyze manufacturer pricing and launch timing strategies under various policies, assessing how removing delay incentives impacts overall welfare. Applied to the dementia drug market, my findings show that a "no exclusivity" policy enhances consumer welfare, even though it introduces the risk that some line extensions might not be developed due to reduced profitability. In contrast, providing "full exclusivity" after the original patent expires leads to significantly higher drug costs for insurers with minimal gains for consumers. Simulations indicate that line extensions with only minor quality improvements are most at risk of not being developed under a no exclusivity policy, which limits consumer welfare losses.Chapter 2 describes a simpler model that provides a high-level approximation of the costs of developing line extensions at a broader scale across all therapeutic classes. This work offers empirical estimates on the cost of developing line extensions but does not make use of the more sophisticated approach, at the cost of not explicitly modeling the individual manufacturer's timing trade-off. The benefit of this approach is that it allows for analysis across the universe of line extensions, rather than focusing on a specific case study. I view this analysis as a good starting point that helps policy makers address the question at hand in a timelier fashion, while still allowing for analysis that approximately captures the main objects of interest well. Both chapters provide a blueprint to potentially combine the two approaches used, to provide a richer analysis as to the consequences alternative reward policies may have if implemented. I believe this is a great avenue for future research, as more detailed data becomes available for researchers and policy makers, and these chapters provide a framework to allow the richer analysis to be conducted.
