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.

We owe Williamson for the formal introduction of hybrid organizations as essential building blocks in ‘the institutional structure of production’. The analysis of these institutional arrangements, which culminated in The Mechanisms of Governance, provided a unified approach to the variety of setting within which transactions are embedded, opening a new perspective on a cornerstone of modern economies. This essay explores the past, present, and future of this breakthrough. First, it reviews the progressive integration of hybrids as a category of their own in the classic ‘make-or-buy’ model, inserting hybrids as an ‘intermediate’ form different from markets in that adaptation cannot be done unilaterally and different from ‘unified organizations’ in that adaptation cannot be done by fiat. Second, it shows how this initial characterization of hybrids, besides providing a coherent approach to empirical research available at the time, gave a powerful impulse to new contributions, identifying more rigorously the fundamental features of hybrids, throwing light on why firms go hybrid, and explicating the governance structure chosen. Last, it offers insights on a research program that remains a work in progress, delineating new terrains to explore and new puzzles to solve.

Agriculture has seen a steady movement toward the increased use of contracts. Agricultural contracts now guide the interrelationships of parties throughout the modern production system, extending well beyond the livestock sector. With this predominance come new issues that require us to reexamine contract theory and the roles of the parties. This review examines legislation, regulations, and recent court rulings in seemingly unrelated areas that have specific relationships to the development of contracts in production agriculture: environmental law and labor law.

London's seventeenth-century goldsmiths are routinely said to have pioneered fractional-reserve banking in England by clandestinely lending coin they were supposed to store – that is, by embezzling their clients. I draw upon both contemporary testimony and contemporary English law to show that the goldsmiths were almost certainly innocent of the crime for which they are so often accused. I then go on to speculate that the myth of the embezzling goldsmith may have its roots in confusion of that crime with (1) crimes other than embezzlement of which goldsmiths were accused by their contemporaries and (2) embezzlement of stored coin not by goldsmiths but by the British crown and by some merchants' servants.

In this paper, the unilateral divorce law is modelled through the combination of exclusive rights on the marriage dissolution and alternative compensation rules benefiting to the parent having custody of the children. Their influence are studied both in the short run (probability and efficiency of divorce) and in the long run (selection of marriages). We show that a decrease in the costs of divorce proceedings has by no means commonplace consequences on marriage contracting; particularly when consideration of parents' altruism and child support is introduced, more marriages are contracted when the cost of divorces decreases.
