Sociologists, Economists, and Opportunism
指出市场与层级范式中两个最有影响力的表述（Williamson和Ouchi的）基于不同甚至对立的人性动机假设，并强调需要厘清差异并实证检验，以推动该研究纲领的发展。
The markets and hierarchies paradigm holds out the promise of a general theory of the conditions under which organizations come into existence. This paper argues that the two most influential statements of the paradigm (Williamson's and Ouchi's) rest on different—indeed competing—assumptions regarding human motivation. A viable program of research requires that the differences and their implications be carefully spelled out and confronted empirically.
