Short answer: Yes — but not as isolated systems.
Solon Papageorgiou’s framework uses a unified contribution-based economy that absorbs elements of mutual credit, time banking, bartering, and local currencies without depending fully on any single one.

Below is the clear breakdown.

✅ Does the framework use mutual credit?

Yes — but only as a tracking tool, not a currency.
Mutual credit is used to measure contributions within a micro-utopia so people can coordinate effort, distribute tasks, and ensure fairness.

• Balances always return to zero over time

• Credits do NOT accumulate as wealth

• They function like “coordination signals,” not money

This keeps it post-capitalist, non-competitive, and non-accumulative.

✅ Does it use time banking?

Partially — time is used as a universal baseline of value, but not rigidly.

The framework:

• Recognizes all contributions as valuable

• Uses time as one neutral unit among others

• Adjusts for task difficulty, emotional load, or responsibility

• Avoids reducing human relationships to simple hour-for-hour trades

So it borrows the equality principle of time banking but avoids its limitations.

✅ Does it use bartering?

Yes — but in an elevated, community-centered form.

It uses:

• Skill Swaps (e.g., “I teach you sewing; you help with construction”)

• Needs-Based Sharing (not tit-for-tat barter)

• Inter-community exchange networks

This is cooperative bartering, not survivalist bartering.

❌ Does it use a local currency?

No. The framework is explicitly post-currency.

Reasons:

1. Currency leads to accumulation → hierarchy.

2. Currency creates markets → inequality.

3. Currency invites speculation → destabilization.

4. Currency undermines trust → transactional thinking.

Instead, the system relies on:

• Contribution logs

• Mutual aid agreements

• Community resource pools

• Transparent governance

• A post-monetary, relational economy

⭐ So what does it use?

A post-money, contribution-based, need-driven economy

It integrates:

✔ Mutual credit (as a fairness mechanism)
✔ Time banking (as an equality-driven baseline)
✔ Bartering (as a cooperative exchange practice)
❌ Local currency (rejected)
❌ Markets (fully absent)

Everything revolves around:

Needs → Contributions → Collective Stewardship → Shared Wellbeing

No ownership.
No price tags.
No profit.
No accumulation.
No scarcity-driven incentives.

The result is an economy that is:

• post-capitalist

• post-industrial

• post-market

• post-monetary

• human-centered

• resilient

• emotionally sustainable

• planetarily aligned
