Resumen del documento: Though antitrust authorities have historically focused on prices in merger analyses, there is now growing interest in the impact of mergers on non-price outcomes. In this paper, we examine the effect of horizontal mergers on product variety in the U.S. beer industry. Our difference-in-differences analyses provide evidence that acquired firms increase variety available to consumers by expanding into new markets, while reducing the variety of products sold in their existing markets in part due to a decreased rate of product development. Back of the envelope calculations suggest that in aggregate, these acquisitions have a net positive effect on product variety. lidity of such mechanisms. I conclude that there exists statistical evidence of the validity of these mechanisms.
