Mark Armstrong (born December 1964) FBA is a British economist and professor of economics at University College London (UCL). He is known for his research in industrial organisation,focusing on oligopoly theory,consumer search and information frictions,and pricing decisions by platforms and other multi-product firms.
Armstrong’s research is primarily in industrial organisation,focusing on how firms and consumers behave in imperfectly competitive markets. His work has examined topics such as oligopoly theory,consumer search and information frictions,price discrimination,and pricing by multi-product firms and digital platforms.
He has made pioneering contributions to the analysis of platforms and two-sided markets,showing how platforms set prices and balance participation on both sides of a market.[6] His research on consumer search has explored how limited information and search costs shape competition,product quality,and pricing outcomes.[7]
With long-term collaborator John Vickers,Armstrong has studied topics including regulation,access pricing,price discrimination and bundling,consumer search,and multiproduct pricing.[8]

Armstrong has held numerous professional and editorial positions during his career. He has served on the councils and executive committees of the European Economic Association (2010–2015),[9] the Royal Economic Society (2010–2015),and the Econometric Society (2016–2019).[10] He is also the President-elect of the European Association for Research in Industrial Economics (EARIE).[11]
