# DBIS Economic Entanglement Index (EEI)

## Purpose

EEI measures how tightly economic states are entangled across realities.

## Entanglement Equation

```
EEI = cohesion_factor - divergence_pressure + quantum_resonance
```

A high EEI indicates strong multiversal economic stability.

## Components

- **Cohesion Factor**: Measures how well economic states align across realities
- **Divergence Pressure**: Measures how much realities are pulling apart
- **Quantum Resonance**: Measures quantum coherence across realities

## Stability Levels

- `very_high` - EEI ≥ 0.8
- `high` - EEI ≥ 0.6
- `medium` - EEI ≥ 0.4
- `low` - EEI < 0.4
