Works and Thinkers That Inspired Robinson
Robinson's ideas were shaped by a combination of intellectual, economic, and political influences:

- Alfred Marshall: Marshall's neoclassical economics provided a foundation for Robinson's early work, though she later critiqued many of his assumptions.
- Piero Sraffa: Sraffa's critique of neoclassical economics and his work on value and distribution influenced Robinson's thinking on imperfect competition and capital theory.
- Karl Marx: Robinson engaged with Marx's ideas about capitalism, exploitation, and class struggle, particularly in her later work.
- Michal Kalecki: Kalecki's work on business cycles and monopoly capitalism influenced Robinson's development of post-Keynesian economics.
