Collusion expert defines terms including ‘but-for price’ and ‘buyer resistance’ for FT Lexicon

Every week, a business school professor, an expert in his or her field, defines key terms on FT Lexicon, our online economics, business and finance glossary.

Leslie Marx is a professor of economics at Duke University’s Fuqua School of Business. She received her PhD in economics from Northwestern University and her BSc in mathematics from Duke University. From 2005 to 2006, Prof Marx served as the chief economist at the Federal Communications Commission, where she worked on auction design issues for the FCC’s spectrum license auctions and competition issues in media markets and markets for multichannel video programming distribution.

Prof Marx has published extensively in peer-reviewed journals and elsewhere on topics related to industrial organisation, applied game theory, auctions, procurements and collusion. Her published work includes papers on collusive mechanisms, incentives in procurement contracting, slotting allowances and exclusive dealing.
