Identify the name of the person who originated the idea of "monopsony" and explain her idea?

Joan Robinson (1903-1983) developed the monopsony model. While others in the field of imperfect competition were focusing on the monopoly power of sellers, Robinson developed the model for a single buyer. She developed the graphical textbook model of how a single hirer of labor could pay a lower-than-competitive-wage and still attract the profit-maximizing quantity of labor.

As an economist, Robinson had an eclectic career. Not only did she address a wide variety of issues, her philosophical approach to economics changed dramatically. Robinson started her professional life as a neoclassical economist, studying under Alfred Marshall at Cambridge University. As her career progressed, she became a contributor to the more liberal Keynesian economics and ultimately to the somewhat radical post-Keynesian economics.

In addition to her theoretical contributions, Robinson actively engaged in the formation of public policy. In order to combat low wages and lack of bargaining power in monopsony markets, Robinson and her theories supported a number of laws friendly to labor. Three of particular significance was the Wagner Act (1935), which promoted the growth of labor unions; the Robinson-Patman Act (1936), which protected small sellers from the monopsony power of large buyers; and the Fair Labor Standards Act (1938), which established the minimum wage.
