Harrison White has had and continues to have a major influence on contemporary social sciences, but this influence stems less from his work as a whole than from multiple methodological and conceptual innovations. On the one hand, there are his highly mathematical network analysis methods and market theory; on the other, his theoretical work, expressed through his unique use of language. In recent years, and even more so since he passed away, the two lines of influence have tended to converge, as researchers have come to realize that the concepts are directly linked to methodological innovations (particularly around structural equivalence).
