Carl Shapiro

Carl Shapiro is an American economist and professor at the University of California, Berkeley, known for his work in industrial organization, competition policy, and innovation economics. He served as Deputy Assistant Attorney General for Economics at the U.S. Department of Justice's Antitrust Division during 2009-2011. His research has significantly influenced antitrust policy and the understanding of how innovation affects competition in technology markets. The book "Information Rules: A Strategic Guide to the Network Economy," which he co-authored with Hal Varian in 1999, became a crucial text for understanding the economics of digital markets and network effects. Shapiro's work on patent policy and standards-essential patents has helped shape modern approaches to intellectual property rights and technology standards. His research papers and testimony have addressed major antitrust cases, including those involving Microsoft, AT&T, and various tech industry mergers. As a leading voice in competition policy, Shapiro has published extensively in academic journals and served on various economic advisory boards. His contributions to industrial organization theory have earned him recognition as a fellow of the American Academy of Arts and Sciences and the Econometric Society.

Information Rules: A Strategic Guide to the Network Economy (co-authored with Hal Varian) explains the economic principles governing information goods and digital markets, addressing concepts like network effects, switching costs, and standards in technology industries.

Joseph Stiglitz His work on information economics and market competition aligns with Shapiro's focus on industrial organization. His analyses of market power and regulation provide similar insights into competition policy and economic efficiency.

Jean Tirole He examines industrial organization and regulation with comparable depth to Shapiro's approach. His research on platform economics and two-sided markets complements Shapiro's work on network effects.

Dennis Carlton His research in antitrust economics and industrial organization parallels Shapiro's contributions to competition policy. His work on vertical integration and market power offers similar analytical frameworks for understanding modern market structures.

Herbert Hovenkamp His analysis of antitrust law and economics mirrors Shapiro's approach to competition policy. His work bridges legal and economic perspectives on market competition, similar to Shapiro's practical applications in antitrust cases.

David Evans His research focuses on platform economics and digital markets, building on concepts similar to those in Shapiro's "Information Rules." His analysis of multi-sided platforms provides frameworks for understanding network industries and digital competition.
