I want to know the answer to the following question:
What ideas were utilized in von Neumann's ecocomic model?
All the background I'm provided with is that "In the proceedings of a conference on von Neumann's growth model, Paul Samuelson said that many mathematicians had developed methods useful to economists, but that von Neumann was unique in having made significant contributions to economic theory itself.". Is that enough to answer the question?
Answer: no
