Ronald Coase (1910–2013) was the most prominent economic analyst of law and the 1991 Nobel Prize-winner. His first major article, "The Nature of the Firm" (1937), argued that the reason for the existence of firms (companies, partnerships, etc.) is the existence of transaction costs. Rational individuals trade through bilateral contracts on open markets until the costs of transactions mean that using corporations to produce things is more cost-effective.
