Why Economics Cannot Behave Like Physics
Carlsson-Szlezak argues that mainstream economics places too much faith in stable quantitative relationships. Economic variables are shaped by changing human behavior, politics, institutions, and idiosyncratic shocks, so models should be treated as sketches rather than truth-generating machines.
- Mainstream economics remains overly model based
- Economic relationships lack the stability found in natural sciences
- Models are useful starting points but poor substitutes for judgment
- Economists should communicate uncertainty with humility
“I generally view all of mainstream economics as as too model based, master model mentality.”
“They are always a good starting point.”
