James Buchanan (2001 p. 29) avers that mutuality of advantage from voluntary exchange is ... the most fundamental of all understandings in economics. He further contends that this fundamental understanding is better realized by examining economics through the lens of contract rather than the lens of choice (Buchanan, 1975). Because the latter has been the reigning paradigm in economics during the 20th century (Lionel Robbins, 1932; Melvin W. Reder, 1999), the lens of contract is (understandably) less fully developed. Interest in contractual approaches has nevertheless been building up, whence the gap between these two has been closing. This paper sketches some of these developments, with emphasis on private ordering.
