What is Exogenous Growth?§
Exogenous growth is a concept from neoclassical economic theory that posits economic growth is influenced by technological progress that occurs outside the economic forces of production, consumption, and market interactions. In simpler terms, it’s as if a magic fairy wand waves over the economy, sprinkling technological fairy dust to make everything grow — independent of how hard you work!
Key Points§
- Economic growth is driven by technological advancements that are not influenced by economic conditions.
- Factors such as production efficiency, capital returns, saving rates, and technology interact to shape economic growth.
- The model emphasizes that while technology fuels growth, the process is largely external to economic policies under consideration.
Exogenous Growth vs Endogenous Growth§
| Feature | Exogenous Growth | Endogenous Growth |
|---|---|---|
| Source of Growth | External technological changes | Internal economic factors and conditions |
| Role of Technology | Technology changes are viewed as external shocks | Technology is a result of economic variables and decisions |
| Policy Influence | Limited influence on tech advancements | Strong influence; policies can enhance innovation |
| Long-term Growth Model | Generally steady, with diminishing returns from capital | Encourages sustained growth through investment in human capital and innovation |
