What is Price Discrimination?

Price discrimination in merger and competition analysis refers to firms charging different prices to different customers based on observable characteristics, with implications for market power, welfare, and post-merger pricing strategies in industries like airlines and medical devices.

This subtopic covers third-degree, second-degree, and personalized pricing models tested empirically using data from airlines, pharmaceuticals, and e-commerce. Key papers include Grennan (2013) on bargaining in medical devices (310 citations) and Levine (1987) on airline deregulation (303 citations). Over 10 high-citation papers from 1987-2019 analyze discrimination's profitability and rivalry effects.

Key Challenges

Why It Matters

Price discrimination reveals how mergers enable firms to extract consumer surplus via targeted pricing, informing antitrust regulators on market power thresholds. Grennan (2013) shows bargaining-driven discrimination in medical devices raises prices by 10-20%, affecting healthcare costs. Levine (1987) demonstrates airlines post-deregulation used discrimination to sustain profits amid competition, guiding merger reviews in concentrated markets like e-commerce platforms (Evans, 2003). These insights shape FTC guidelines on big data pricing.

Key Research Challenges

Empirical Detection

Distinguishing price discrimination from cost differences requires audit data or structural models, as audits capture average firm behavior rather than marginal discrimination (Heckman, 1998). Grennan (2013) uses panel data on medical devices to quantify bargaining effects, but data access limits replication.

Welfare Measurement

Quantifying consumer surplus loss versus efficiency gains post-merger demands counterfactual simulations. Levine (1987) analyzes airline deregulation outcomes, highlighting ambiguity in discrimination's net welfare impact. Evans (2003) notes multi-sided platforms complicate welfare assessment.

Bargaining Heterogeneity

Modeling buyer-seller negotiations in B2B markets like devices yields ambiguous theoretical predictions (Grennan, 2013). Insiders-outsiders dynamics add complexity to pricing power (Lindbeck and Snower, 2001).

Global supply chains have transformed the world. They revolutionised development options facing poor nations – now they can join supply chains rather than having to invest decades in building their...

Price Discrimination and Bargaining: Empirical Evidence from Medical Devices

Matthew Grennan · 2013 · American Economic Review · 310 citations

Many important issues in business-to-business markets involve price discrimination and negotiated prices, situations where theoretical predictions are ambiguous. This paper uses new panel data on b...

AIRLINE COMPETITION IN DEREGULATED MARKETS: THEORY, FIRM STRATEGY, AND PUBLIC POLICY

Michael E. Levine · 1987 · Yale Law School Legal Scholarship Repository · 303 citations

How airlines compete and the desirability of government intervention to control airline competition must be among the most studied of regulatory questions. Airlines were highly regulated by 1938 in...

Reading Guide

Foundational Papers

Start with Heckman (1998) for discrimination detection methods, then Grennan (2013) for empirical bargaining in B2B markets, and Levine (1987) for airline competition strategies to build core frameworks.

Recent Advances

Study Bloom et al. (2019) on management practices driving pricing dispersion and Fonseca and Normann (2012) on collusion impacts, extending to modern merger contexts.

Core Methods

Structural estimation of bargaining (Grennan, 2013), audit audits (Heckman, 1998), deregulation simulations (Levine, 1987), and platform demand coordination (Evans, 2003).
