Joan Robinson (1903–1983)

Who They Were

Joan Robinson (1903-1983) was a British economist and one of the most prominent members of the Cambridge school in the twentieth century. Working closely within the circle around John Maynard Keynes, she became a leading figure in the development and extension of Keynesian and post-Keynesian economics. Over a long career she contributed to debates on competition, capital, growth and the foundations of economic theory, and she was known as a forceful and independent thinker who often challenged mainstream orthodoxy. Her early work in the 1930s helped reshape the theory of markets, and she remained influential in heterodox economics for decades. She is frequently cited as one of the most important economists never to receive the Nobel Prize.

Key Contributions

Robinson's best-known early contribution is The Economics of Imperfect Competition (1933), part of a wave of 1930s work that made explicit the tight relationship between the elasticity of demand facing a firm and its marginal revenue, and therefore its pricing power. This helped move economics beyond the extremes of pure competition and pure monopoly toward a richer analysis of real markets. She is also credited with popularising the term monopsony for a market with a single dominant buyer, a concept now widely used, including in labour economics. Building on the Keynesian tradition, she contributed to later debates on growth and capital theory. Her work on price elasticity and market structure places her among the key economists who developed these tools, alongside figures such as Cournot and Alfred Marshall.
