Endogenous economic growth theories emphasize that economic growth is primarily driven by internal factors within an economy, such as human capital, innovation, and knowledge, rather than relying solely on external forces like technology or natural resources. The objective is to explore the key theories of endogenous growth, their implications for policy, and their impact on long-term economic performance. The difference from classical theories is that endogenous growth models argue that technology and innovation can be influenced by internal actions.
