Endogenous Growth Theory
Updated 2026-08-05
INTRODUCTION
English translation pending.
CORE DEFINITION
Against the Solow model, which treats technology as an exogenous stroke of luck, Paul Romer's endogenous growth theory holds that technological progress arises inside the economy through investment in knowledge and ideas. Ideas are non-rival, meaning your use does not block mine, so they can generate increasing returns to scale and break the growth limit. In the knowledge economy, investment in recipes pays unbounded returns, which is the strongest economic argument for learning and research as the only inputs that compound exponentially.
SCAFFOLDING EFFECT
Reduce cognitive load
- Recipe investing: treat ideas and methods as the asset with non-rival returns. - Non-rivalry leverage: ask how the same idea can serve another unit at near zero marginal cost. - Compounding horizon: fund learning and research on the argument of scale, not on cost.
Anchor fast decisions
Knowledge is non-rival, so an idea can be reused across the whole economy without depletion and its returns add up rather than fade. Investment in research and human capital therefore produces increasing returns, and growth no longer has to decay toward a stationary state.
