Model overview
Solow vs Harrod-Domar
Two foundational growth models compared: the Harrod-Domar model's knife-edge instability against the Solow-Swan model's stable steady state. Covers assumptions, stability, technology, policy implications, and when to use each.
Navigate the learning sections below, then move into the interactive model once you want to experiment with parameters.
Two Models of Growth
The Harrod-Domar and Solow-Swan models ask the same question — what drives long-run growth? — but answer it with incompatible assumptions.
Model Comparison
Seven dimensions that separate the two models, from production function to policy implication.
When to Use Each
The decision rule: which model fits your question, your data, and your context.
A Numeric Example
The same economy seen through two lenses: Harrod-Domar computes a knife-edge growth rate; Solow finds a stable steady state.
