December 2015The Welfare Effects of Vertical Integration in Multichannel Television Markets
with Gregory S. Crawford, Robin S. Lee, Michael D. Whinston: w21832
We investigate the welfare effects of vertical integration of regional sports networks (RSNs) with programming distributors in U.S. multichannel television markets. Vertical integration can enhance efficiency by reducing double marginalization and increasing carriage of channels, but can also harm welfare due to foreclosure and raising rivals' costs incentives. We estimate a structural model of viewership, subscription, distributor pricing, and affiliate fee bargaining using a rich dataset on the U.S. cable and satellite television industry (2000-2010). We use these estimates to analyze the impact of simulated vertical mergers and de-mergers of RSNs on competition and welfare, and examine the efficacy of regulatory policies introduced by the U.S. Federal Communications Commission to addre...
August 2015Multilateral Trade Bargaining: A First Look at the GATT Bargaining Records
with Kyle Bagwell, Robert W. Staiger: w21488
This paper empirically examines recently declassified data from the GATT/WTO on tariff bargaining. We document eight stylized facts about these interconnected high-stakes international negotiations. We use detailed product-level offer and counteroffer data to examine several questions about trade policy, including whether preferential tariffs were a stumbling block towards liberalization, and whether the relaxation of bilateral reciprocity to multilateral reciprocity aided liberalization. We organize the empirical analysis around a theoretical model of multi-party trade negotiations motivated by the terms-of-trade theory and respecting the institutional features of most-favored-nation status and reciprocity.
December 2014Bias in Cable News: Persuasion and Polarization
with Gregory J. Martin: w20798
We measure the persuasive effects of slanted news and tastes for like-minded news. We use cable channel positions as exogenous shifters of cable news viewership. We examine whether channel positions correlate with variables which predict viewership and voting. We estimate that Fox News increases the likelihood of voting Republican by 0.3 points among viewers induced into watching 2.5 additional minutes per week by differential positions. We estimate a model of voters who select into watching slanted news, and whose ideologies evolve as a result. We quantitatively assess media driven polarization, and simulate alternative ideological slanting of news channels.
April 2012Medicare Reimbursements and Shortages of Sterile Injectable Pharmaceuticals
This paper investigates the rise in shortages of sterile injectable pharmaceutical drugs in the US. I examine a policy change in 2005 that differentially reduced Medicare Part B payments for pharmaceuticals. Drugs whose payments dropped more due to the policy change have had greater increases in shortages. I interpret these results using a model of entry and capacity choice with supply uncertainty. I conclude that Medicare's generous payments before the policy change provided manufacturers with incentives to invest in capacity or induced entry. The effect on total welfare of lowering payments is theoretically ambiguous.
