Governmental purchasing in the public policy process: orienting theory and practice

What do purchasing officers and policy theorists have to offer one another? Policy frameworks could help purchasing officers anticipate or predict change and respond to those changes earlier and more effectively. Likewise, purchasing officers and the study of the governmental purchasing systems they operate could contribute a great deal to the development of policy theories or frameworks. This paper outlines the central features of two important policy frameworks; institutional analysis and development (IAD) within the tradition of institutional rational choice (Ostrom, 1999), and the advocacy-coalition framework (Sabatier and Jenkins-Smith, 1999) and applies those frameworks to the government purchasing arena.
