***** To join INSNA, visit http://www.insna.org ***** All, I am very interested in research by Walter. W. Powell and his research from 1990 (see link). Neither Market nor Hierarchy: Network Forms of Organization <http://www.stanford.edu/~woodyp/papers/powell_neither.pdf> . I'm looking for information on any assessment instruments that have been used to measure the degree of market, hierarchy, and network exchange within an interorganizational network. Do you know of any research, surveys, or instrumented that have been used to measure these exchanges?
