This presentation explores endogenous growth theories, their key concepts, models, and real-world implications. Endogenous growth theory explains long-term economic growth as a result of internal factors within an economy, rather than external influences like resource availability or population growth. It emphasizes the role of human capital, technological innovation, and knowledge accumulation in sustaining economic progress. The theory emerged in response to the limitations of the Solow-Swan neoclassical growth model, and key contributors include Paul Romer and Robert Lucas.
