Understanding Exogenous Growth
Exogenous growth theory, a cornerstone of neoclassical economic thought, propositions that economic growth is spurred by technological improvements that originate outside the economic system itself. Unlike its cousin, endogenous growth, which finds the seeds of economic expansion sewn within the internal mechanisms of the economy, exogenous growth looks externally for its growth vitamins.
Key Takeaways
- Foundation in Neoclassical Economics: Exogenous growth is rooted in a school of thought where factors outside the economic playground, like technological innovation, play pivotal roles.
- Comparison with Endogenous Growth: While exogenous growth claims “growth comes from outside,” endogenous growth argues “we can grow our own internally,” emphasizing the role of factors within the economy.
- Impact on Economic Models: Delve into how exogenous factors like technology and savings rates are essential cogs in the machinery of economic models such as the Solow-Swan model.
Exogenous vs. Endogenous Growth: The Eternal Economic Tug-of-War
In the grand arena of economic theories, the battle between exogenous and endogenous growth theories is akin to a thrilling intellectual chess game. Exogenous growth theory waves the flag of external influences—primarily technological advancements and fixed savings rates—as the knights and bishops driving economic growth. On the opposing side, endogenous growth strategy rallies around the idea that an economy can internally generate its growth steroids through factors like innovation and investments in human capital.
Theatrical Plays in Economic Theories
To compare, think of exogenous growth as the mysterious benefactor in a play, whose sudden generosity solves all problems out of the blue. In contrast, endogenous growth is more of a self-made protagonist who pulls themselves up by their bootstraps, driving the narrative from within.
