Owning the Machine: A Governance of Abundance for Europe

AGORA is an open, stock-flow-consistent simulation of the European economy, built to compare AI-era economic policies under transparent, swappable assumptions rather than to forecast. It is calibrated to live 2019 data for 26 EU member states (Eurostat, AMECO, BIS, OECD, FIGARO input-output) and back-tested against 2010–2019 history, reproducing realised GDP to roughly one percent; a consistency gate rejects any scenario that violates the national accounts. Using it, we show that an AI labour-share shock concentrates not only income but wealth, and that cash transfers (UBI) compress income inequality while leaving the ownership of capital — the compounding stock — untouched. Only an ownership instrument, Universal Basic Capital (a citizens' sovereign fund paying a per-capita dividend), reaches the wealth dimension; with fund reinvestment it need not reduce output; and a pooled European dividend roughly halves between-country inequality. Across a multi-objective policy frontier, ownership-based policies dominate both cash transfers and inaction. All code, data and figures are open and reproducible. This is a sandbox, not an oracle: the contribution is a shared, auditable instrument for a debate usually conducted without one.
