|December 2015||The 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 incentives to raise rivals' costs. 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 divestitures of RSNs on competition and welfare, and examine the efficacy of regulatory policies introduced by the U.S. Federal Communications Commission to add...
|August 2015||Multilateral 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 2014||Bias 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, exploiting cable channel positions as exogenous shifters of cable news viewership. Channel positions do not correlate with demographics that predict viewership and voting, nor with local satellite viewership. We estimate that Fox News increases Republican vote shares by 0.3 points among viewers induced into watching 2.5 additional minutes per week by variation in position. We then 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 2012||The Role of Government Reimbursement in Drug Shortages|
with Eli Liebman, David B. Ridley: w17987
Beginning in the mid-2000s, the incidence of drug shortages rose, especially for generic injectable drugs such as anesthetics and chemotherapy treatments. We examine whether reimbursement changes contributed to the shortages, focusing on a reduction in Medicare Part B reimbursement to providers for drugs. We hypothesize that lower reimbursement put downward pressure on manufacturers’ prices which reduced manufacturers’ incentives to invest in capacity, reliability, and new launches. We show that, after the policy change, shortages rose more for drugs with (i) higher shares of patients insured by Medicare, (ii) greater decreases in provider reimbursement, and (iii) greater decreases in manufacturer prices.
