Consumer Data as a Lever for Market Competition

Intermediaries can strategically control the release of consumer preference data to influence market competition and outcomes.

The Review of Economic Studies · 2026

01

Key Findings

  • 01Intermediaries can use precise consumer data to intensify or soften competition among firms.
  • 02The strategic release of information can impact both consumer and producer surplus.
  • 03The power of intermediaries is directly linked to the depth and precision of user data they possess.
02

Application

Design takeaway

When designing digital platforms or services that involve multiple competing entities, consider how the controlled release of aggregated or anonymized user data can be used as a strategic tool to influence market dynamics.

How to apply

When developing a new marketplace or platform, consider the role of data disclosure as a competitive lever. Design the information flow to achieve desired market outcomes, whether it's fostering intense price competition or encouraging product differentiation.

Project actions

  • 01Consider the role of information flow in your design project.
  • 02Think about who controls the information and how that control impacts users or businesses.
03

Method & Evidence

AimHow can an intermediary strategically design information disclosure to consumers and firms to influence market competition and maximize overall welfare?
MethodGame Theory / Economic Modelling
ProcedureThe study models a scenario where an intermediary acts as an information designer, deciding what consumer preference data to reveal to competing firms. These firms then engage in price competition within a differentiated product market.
ContextDigital marketplaces and platform economics

Variables

IVInformation disclosed by the intermediary about consumer preferences.
DVMarket competition (e.g., prices, product differentiation), consumer surplus, producer surplus.
CVNumber of firms, nature of the product market, consumer demand characteristics.
04

Strengths & Limitations

Strengths

  • +Provides a formal economic model to analyze a complex market dynamic.
  • +Connects theoretical findings to contemporary issues in digital platform regulation.

Limitations

The abstract does not detail the specific types of competition modelled (e.g., price, quantity, quality) or the exact nature of the product differentiation.

Reliability & validity

The validity of the model relies on the assumptions of rationality and the accuracy of the economic framework. Reliability would depend on the robustness of the model to variations in its parameters.

Think critically

To what extent can an intermediary's information design be considered a form of market manipulation, and what ethical considerations arise from this power?

05

Design Principles

"Information asymmetry, strategically managed by an intermediary, can be a powerful determinant of market structure and outcomes."

Understanding how information is managed by intermediaries is crucial for designing effective market strategies and for policymakers aiming to regulate digital platforms. This research highlights the significant power that data analytics and information design can wield in shaping competitive landscapes.

06

What This Means for Your Design

Imagine a shopping website that knows exactly what people like. This website can decide to tell some shops what customers want, making those shops compete harder, or it can hide that info to make competition less fierce.

How to use in your project

  • 1.Discuss how the intermediary's information design choices impact the competitive landscape and user welfare in your analysis.

Paragraph starter

This research by Elliott, Galeotti, and Koh (2026) highlights the strategic potential of information intermediaries in shaping market competition. Their work demonstrates that by controlling the release of consumer preference data, an intermediary can influence the intensity of competition among firms, thereby impacting consumer and producer surplus. This has significant implications for the design of digital marketplaces, where data management practices can be leveraged as a competitive strategy.
