Since the first minimum wage legislation was introduced in Australia, the United Kingdom and the United States in the early 1900s, minimum wage regulation has attracted controversy. Opponents of minimum wage levels rely on market theory, while supporters acknowledge the role of markets in setting the price of labour but justify state intervention based on principles of equity and social good. This article examines how these two ideological positions influenced fixing what is both a crucial cost for business and underpinning of worker and family living standards, and whether effective wage fixing has resulted. Little comparative research exists on the origins, evolution and current systems of minimum wage regulation in the three countries and this article aims to address this gap in the literature.
