About the Model
The Productivity Bond Model is a sovereign debt instrument designed to replace perpetual‑growth‑dependent financing with productivity‑linked prosperity. It is the first financial instrument that explicitly acknowledges the finite nature of our planet and aligns economic incentives with ecological reality.
Origin & Research
The model was developed as part of the Traffic Torch research initiative. It draws on decades of economic theory, including Piketty's r > g, planetary boundaries, state‑contingent debt instruments, and common‑pool resource governance. The result is a practical, market‑based solution that turns the financial system from a driver of instability into a stabilising force.

Research Philosophy
The model is built on three pillars:
- Finite planet – economic activity must respect ecological limits.
- Shared prosperity – productivity gains should benefit all citizens, not just investors.
- Transparency and trust – the NPI is legally locked and independently audited.
Open Source & Collaboration
The model is fully open source. You can fork the repository, run simulations yourself, and contribute to the development. All code is licensed under the MIT License.
