Rebecca Haw Allensworth

Associate Professor of Law

Rebecca Haw Allensworth studies the theoretical basis of antitrust's rule of reason and its implications for industry and professional self-regulation. Her work explores the procompetitive justifications for self-regulation, from appeal to expertise to arguments about market failure, and argues that courts can and should balance these justifications against the anticompetitive potential that inheres whenever competitors set their own rules of play. Professor Allensworth was a Climenko Fellow at Harvard Law School from 2009 to 2011. Before accepting her Climenko Fellowship, she was a law clerk for Judge Richard A. Posner of the U.S. Court of Appeals for the Seventh Circuit in 2008-09. Professor Allensworth earned her undergraduate degree in English at Yale, an M.Phil. in American literature at Cambridge University and her J.D. at Harvard Law School, where she was a research assistant to Professors Bruce Hay (2007) and Elizabeth Warren (2006) and served as articles editor of the Harvard Law Review. Professor Allensworth teaches Contracts, Antitrust Law and a seminar, Expertise in Law.
