Learning objectives
- Explain economic model vs econometric model in plain language.
- Use economic model correctly in an interpretation.
- Connect the lesson idea to a formula, graph, Python result, or real example.
Simple explanation
An economic model explains how we think the world works. An econometric model turns that idea into an equation connected to data and uncertainty.
Key terms
- Economic model
- A simplified idea about how economic variables are related.
- Econometric model
- An estimable equation that connects the idea to measured data.
- Simplification
- Leaving out details to focus on the relationship of interest.
- Measurable variable
- A concept that has been turned into data.
From idea to equation
Example
The economic idea is that education can build skills. The econometric model relates measured education to measured wages.
