The Australian stockbroking sector has been at the forefront of integrating information systems (IS) in its daily operations. Trade and clearance account for a large percentage of processes undertaken in a brokerage house. Upon integration of IS, the trade and clearance processes of the sector were centralised and the institutional arrangements of the sector were transformed. Centralisation also meant that this large percentage of processes was directly controlled by the Australian Stock Exchange (ASX) and the Australian Securities and Investment Commission (ASIC). Although the integration of IS was intended to rationalise the trading regime and make the process of brokerage identical across the industry, there are many types of brokerage houses - each catering to a specific group of customers. This interplay between the intent to homogenise the sector by the regulatory authority and the move by the brokerage houses to strategically differentiate from peers motivated this research to explore the dynamics of the diffusion of IS adoption and its resultant structural changes in the stockbrokerage sector.
