Mechanics of market definition
Should you pick up a newspaper or watch the evening news, chances are you will see or hear a story about the Trade Practices Act 1974 (Cth) (the TPA) or its administering body, the Australian Competition and Consumer Commission (the ACCC). Whether the details involve claims of price fixing in a particular industry, a planned merger between competing firms, a refusal by a powerful corporation to deal with others in the chain of supply, or other allegations of anti-competitive behaviour, invariably the provisions of the TPA will be relevant.
