Transaction Cost Applications in Information Systems: Explicating Institutions' Influences on
Governance

Institutions' influences on transaction costs and on the comparative efficacy of alternative governance structures, in particular, contribute to the transaction cost frameworks currently deployed in information systems.  This thesis shows how more accurate
judgements can be exercised regarding costs and benefits of information systems developments supporting
alternative governance structures where the costs and competencies of such structures are influenced in varying
extents by factors emaneting from the institutional environment in which transactions are embedded.

Empirical work is carried out on two case studies involving (a) information systems supporting the internal
market transactions between purchasers and providers in the National Health Service in relation to and (b)
information systems supporting various market and hierarchy transactions of a manufacturing firm in the
developing country context of Turkey.
