Robinson's work was highly influential in the field of Economics. Her book The Economics of Imperfect Competition contributed heavily to the idea of monopolistic competition. It is one of the main reasons why most economists believe that industries/firms are neither perfectly competitive or completely monopolistic. Robinson was also the first to define macroeconomics, which was later described in one of Keynes' books.
Robinson's work is especially important because she questioned norms (in Economics and in the world as a whole) and shared ideas which sparked debate. For example, she claimed that capital cannot be fully aggregated or measured. She also insisted that economics is about real world problems. She brought attention to many issues in the world, including the dangers of capitalism and the arms race. She did not go easy on herself and encouraged students to work hard and admit to what they did not know.
I only heard about Robinson briefly before this course, when my AP Economics teacher in high school told us that it was actually a woman (Robinson) who first defined macroeconomics. Her work will be very influential/important in class as we discuss the problems organizations face and think about how things "could have been" in contrast to what they are. Robinson's influential work questioned existing standards in Economics, and hopefully we will continue to question the standards that organizations hold themselves up to.
