Abstract We examine the consequences of real earnings management from an innovation perspective and investigate the patent output of firms likely to be managing earnings through altering their R&D expenditures. We find that R&D cuts related to earnings management lead to fewer patents, less influential patent output, and lower innovative efficiency compared to other R&D cuts. Our results thus suggest that real earnings management may obstruct firms’ technological progress and highlight the potential costs of managerial manipulation of R&D expenditures to alter reported earnings.
