    Knowledge capital refers to the available knowledge and technology, while human capital refers to the skills and education of workers.

    Knowledge capital leads to increasing returns because it benefits not just the firm but the entire economy, unlike physical capital which faces diminishing returns.
  • What does it mean for knowledge to be a public good?
    Knowledge is a public good because it is non-rival (many can use it at once) and non-excludable (others cannot be easily prevented from using it).
  • How can other firms benefit from one firm's R&D according to New Growth Theory?
    Other firms can benefit through free riding, using the knowledge generated by one firm's R&D to improve their own productivity.

  • Besides patents, how else can governments support the accumulation of knowledge capital?
    Governments can offer subsidies, grants, or tax breaks for research and development to encourage innovation.
  • How does investing in education support New Growth Theory's goals?
    Investing in education increases human capital, making research and development more productive and likely to result in technological breakthroughs.
  • What is free riding in the context of knowledge capital?
    Free riding occurs when firms benefit from the knowledge created by others without having to pay for its development.
  • Why is technological change considered crucial in New Growth Theory?
