Joan G. Robinson was a prominent British economist known for her contributions to the field of economic theory. Born in 1903, she became one of the first women to gain recognition in economics, particularly for her work on monopoly and oligopoly markets. Her influential book, "The Economics of Imperfect Competition," published in 1933, challenged traditional economic models and introduced new ideas about market structures. Throughout her career, Robinson was associated with Cambridge University, where she taught and mentored many students. She was also a member of the Fabian Society, advocating for social reform and economic justice. Her work has had a lasting impact on economic thought and policy.
