This article argues that abstract knowledge in the form of formally developed theory plays an increasingly important role in the economy and in financial innovation in particular.knowledge is easily reified, and this is an aspect of knowledge work that is insufficiently researched. In this article, we problematize reification of abstract knowledge in financial innovation from wisdom, ethics, and social network analysis perspectives. This article, therefore, considers the composition and structures of financial innovation networks that help avoid reification by building ethicality (...) through social practice wisdom. Finally, we discuss future directions that empirical ethics research can take. (shrink)
