Ma and Ederer, together with Colleen Cunningham of the London Business School, were honored for their paper “Killer Acquisitions.” The much-cited study, which focuses on the pharmaceutical industry, examines the phenomenon of firms buying competitors for the purpose of terminating projects that pose a threat. Among the author’s conclusions was that such acquisitions disproportionately occur just below the threshold that would subject them to the scrutiny of competition authorities.

Earlier this year, “Killer Acquisitions” won the Robert F. Lanzillotti Prize for best paper in antitrust economics. This month, it was cited in a high-profile congressional report on competition in the technology industry.
