Show HN: Script to determine when government intervention is legitimate
The Armey Curve theory, which suggests an optimal level of government spending for economic growth, does not hold up against real-world data. Instead, countries with lower government spending tend to achieve higher growth rates, contradicting the traditional quadratic model. The data indicates that government spending negatively impacts GDP growth from the first dollar spent, with alternative models like power law providing better explanations for growth variations.
- ▪The Armey Curve proposed an inverted U-shaped relationship between government spending and economic growth.
- ▪Real-world data shows that countries with lower government spending consistently achieve higher growth rates.
- ▪The power law model explains approximately 42% of the variation in growth rates among countries, making government spending a crucial determinant of economic performance.

The theory seemed reasonable: The Armey Curve suggested an inverted U-shaped relationship between government spending and economic growth. Named after economist Richard Armey, this curve claimed there exists an optimal level of government spending that maximizes economic growth. But here's the problem: When you actually look at real-world data from dozens of countries over multiple decades, the theory doesn't hold up. Countries with lower government spending consistently achieve higher growth rates, while high-spending countries cluster in the low-growth zone.
