A dynamic analysis of consolidation in the broadcast television industry
AbstractThis paper estimates a dynamic oligopoly model in order to separately identify the demand-side and cost-side advantages of consolidation in the broadcast television industry. I exploit an exogenous change in regulation that led to significant industry consolidation. Using revenue and ownership data for broadcast stations over the past ten years, I estimate the effect of ownership changes on revenue. I recover costs by examining patterns in ownership changes that are left unexplained by revenue estimation. I model firms' purchasing decisions as a dynamic game, and estimate the game using a two-step estimation method recently developed by Bajari, Benkard & Levin (2007). This is the first paper to estimate a model of merger activity in a dynamic, strategic setting. I find that there are both revenue and cost advantages to consolidation, but they operate through different mechanisms. Access to a wider audience enables firms to increase per-station advertising revenue, while simply owning more stations enables firms to reduce per-station operating costs. A firm's ability to realize these benefits is affected by its stations' network affiliations, locations and viewers.
