Nash-in-Nash Tariff Bargaining with and without MFN (with Kyle Bagwell and Robert Staiger)
We derive some theoretical results on the efficiency properties of Nash-in-Nash equilibrium tariffs under Most-Favored-Nation (MFN) rules and with no MFN restriction.
The Welfare Effects of Vertical Integration in Multichannel Television Markets (with Gregory Crawford, Robin
Lee, and Michael Whinston)
We estimate the welfare effects of vertical integration of upstream regional sports networks with downstream cable distribution firms. We measure efficiencies due to integration (reduction of double marginalization) against potential foreclosure incentives (exclusion and raising rivals' costs). We also analyze regulatory policy towards integrated firms.
We measure the persuasive effects of cable news. We consider these effects in a model where consumers prefer news that is closer to their own ideology. The results suggest that media mergers may raise additional public policy issues compared to mergers in other product markets.
Dynamic Natural Monopoly Regulation: Time Inconsistency, Moral Hazard, and Political Environments (with Claire
Journal of Political Economy, Accepted
Examines infrastructure investment dynamics and degree of power outages under monopoly regulation. We simulate regulatory commitment and explore regulator heterogeneity.
We empirically examine recently declassified offer and counteroffer data from multi-party international tariff negotiations. We document eight stylized facts. We assess the role of relaxing bilateral reciprocity to multilateral reciprocity, and whether preferential tariffs served as a stumbling block for liberalization.
The Role of Government Reimbursement in Drug Shortages (with Eli Liebman and David Ridley)
American Economic Journal: Policy, Accepted
Examines dramatic increase in reported drug shortages and the contribution of changing regulatory reimbursement design. The theoretical framework is an oligopoly with supply uncertainty where manufacturers invest in capacity and face differing reimbursement schemes for their drugs.
The Welfare Effects of Bundling in Multichannel
Television Markets (with Gregory S. Crawford)
American Economic Review, Vol. 102, No. 2, April 2012
Download Code for Estimation and Simulation (Synthetic Data Included)
An empirical model to predict the effects of a la carte pricing regulations in cable television, accounting for the renegotiation of bilateral contracts between upstream content and downstream distribution.
Non-technical overview on research related to bundling, programming costs, vertical integration, and social effects of the media.
