Özet:
Chapter 1 builds a structural model to analyze the effects of mergers, taking into account not only changes in prices but also adjustments in product portfolios. Merging firms that offer similar products may have incentives to eliminate closely competing products to save on fixed costs. For instance, the second and third largest shampoo manufacturers merged in 2011 and dropped 20 percent of their products after the merger. Leveraging the post-merger data from the shampoo market, I find that my model correctly predicts 7 out of 9 products that were dropped. A standard merger simulation focusing only on price understates the loss of consumer surplus. In contrast, the enriched model captures both changes in prices and product portfolios, and delivers a more accurate prediction for consumer surplus.
Chapter 2 tests the intensity of competition between bars and grocery stores in the market for beer, taking advantage of the variation created by the repeal of the private club law in Utah. Applying a difference-in-differences approach to the IRI dataset, I find that average grocery beer price fall by 1.5 percent, absent the private club law. For stores located close to bars, the effect of the policy change is to decrease beer revenue and sales. After abolishing the law, there was also an overall reduction in the number of bars and a shift from the smallest bars to larger bars in Utah. These results suggest that competition between on- premises and off-premises consumption should be taken into consideration in economic studies.
