Source of complexity in the social and managerial sciences: an extended Sen’s theorem

Abstract

Many disciplines, including the social, behavioral, and management sciences, search for appropriate aggregated outcomes—a search that can be frustrated by complexities and inefficiencies. As shown here, explanations for these difficulties can be found in social choice. Indeed, it is shown why some of these problems are direct consequences of adopted approaches (e.g., management style, choice of a division of labor, or even the use of expertise and experts), and they cannot be avoided. These results are motivated by Sen’s Theorem from decision theory.
