Williamson's legacy will be permanently, and deservedly, linked with the theory of the firm. As important, however, is his contribution to our understanding of contracting. My aim here is to describe Williamson's conception of contracting, how it differs from other approaches to contracting, and some implications of that approach for contract design and enforcement. I argue that Williamson's ‘process orientation’ – in which the main dimension along which contracts vary is the extent to which contract adjustments are effected through court ordering versus private ordering – provides alternative interpretations of some conventional contract terms but also sheds light on some otherwise puzzling contractual phenomena.

This contribution commemorates Oliver Williamson, who recently passed away, as one of the founding fathers of Transaction Cost Economics (TCE). It does so by touching on some of the details of his personal life and connecting these with his professional career. The latter was devoted to putting the study of institutions on the economic agenda. Closer scrutiny reveals that three phases may be identified. Williamson first developed an interest in analysing vertical integration. During the second phase, he elaborated this interest in TCE, and during the third, he positioned his contributions within the area of institutional economics. Furthermore, the article considers the various influences of institutional and organizational economists on Williamson. Finally, the article considers the reception, criticism, and further elaborations of Williamson's contributions.

In this essay, we honour the memory of Oliver Williamson by reflecting on Chiles and McMackin's 1996 Academy of Management Review article ‘Integrating variable risk preferences, trust, and transaction cost economics’. The article, which built on Williamson's work in transaction cost economics (TCE), went on to attract attention not only from the authors’ home discipline of management and organisation studies, but also from other business disciplines, the professions and the social sciences. After revisiting the article's origins and core arguments, we turn to selectively (re)view TCE's development since 1996 through the lens of this article, focusing on trust, risk and subjective costs. We cover conceptual and empirical developments in each of these areas and reflect on how our review contributes to previous debates concerning trade-offs implicit in relaxing TCE's behavioural assumptions. We conclude by reflecting on key points of learning from our review and possible implications for future research.

Joseph Campbell describes a narrative pattern for a hero's journey. ‘A hero ventures forth from the world of common day into a region of supernatural wonder: fabulous forces are there encountered and a decisive victory is won: the hero comes back from the mysterious adventure with the power to bestow boons on his fellow man’ (2008: 30). This paper looks at Oliver E. Williamson's life through Campbell's lens and reveals his journey, challenges, and triumphs not only for himself but also for all students of the science of organization.
