Invention Value, Inventive Capability and the Large Firm Advantage
Large firms have an advantage in innovation. A new model shows that large firms are better at commercializing new inventions. The advantage is less in sectors where innovators can easily license technologies to other firms.
Should I Stay or Should I Go? Migrating Away from an Incumbent Platform
Incumbents enjoy competitive advantages over new entrants, because users hesitate to abandon a widely-used platform for one with few users. A new model explores factors that increase and reduce incumbency advantage.
How Platforms Create Value Through Coring and Implications for Market Definition
Digital platforms coordinate interactions between user groups, an activity known as "coring." When analyzing coring conduct, antitrust courts should avoid defining the platform’s market too narrowly.
Big Data, Little Chance of Success: Why Precedent Does Not Support Anti-Data Theories of Harm

Antitrust Policy toward Intermediaries: Digital Platforms and “Big Tech”
Antitrust authorities express concerns about the power of "Big Tech." Authorities should apply advances in the study of platforms to better understand the beneficial role of digital platforms serving as intermediaries.

Reclaiming Spectrum from Incumbents in Inefficiently Allocated Bands: Transaction Costs, Competition, and Flexibility

Understanding AI Collusion and Compliance
Artificial intelligence (AI) allows firms to adopt new types of anti-competitive behavior, but may also aid in the detection of such behavior. AI collusion could include non-price elements, such as product reviews and ratings.
Restrictions on Privacy and Exploitation in the Digital Economy: A Market Failure Perspective
