Аннотация:This article sets the idea of the `institutional entrepreneur' in the context of the `autonomous reflexive' as developed in the work of Margaret Archer. It argues that the latter notion provides a helpful approach to the issue of agency that has bedevilled the new institutionalist project. A detailed account, using the lens supplied by the notion of the autonomous reflexive, is given of the formation of Sir Andrew Barclay Walker, a pioneer of directly managed public houses. The article suggests that Walker used taken-for-granted practice, transferred from elsewhere, to develop his managerial systems. The importance of aspects of Walker's Scottish background, such as education and church governance, is stressed. The account of agency supplied by Archer is seen to be a conception of agency that can inform the debate over the nature of institutional entrepreneurship.
