Key Concepts

Endogenous Technological Change

This concept highlights that technological progress originates within the economy as a result of intentional activities such as research and development, innovation, and human capital investment, rather than being treated as an external or exogenous factor. It shifts the focus to factors within the economy that can generate sustained growth.

Knowledge Spillovers and Increasing Returns

New growth theory emphasizes that knowledge, unlike physical capital, can be reused by multiple agents without depletion, leading to positive spillovers. These spillovers create increasing returns to scale, where additional inputs can lead to more than proportional increases in output, fueling long-run economic growth.

Human Capital and Innovation

The theory places a central role on human capital, suggesting that investments in education, skills, and training enhance the innovative capacity of the workforce. This improved human capital is essential for generating new ideas and technologies that drive continuous economic expansion.

Policy Implications for Sustained Growth

By recognizing that growth can be driven from within the economy through innovation and knowledge creation, new growth theory suggests that government policies aiming at improving education, supporting R&D, and fostering innovation can have a significant and lasting impact on economic performance.
