The correct question is not “state or market?” but rather: what kind of profit, in what kind of sector, under what informational and energetic conditions? The model is built around three distinct governance instruments that interact differently with sector structure.
For each sector and year , the simulation evolves knowledge, deployment, concentration, and profitability as coupled nonlinear processes:
The welfare index aggregates consumer benefit, state capacity, and resilience, penalized by inequality and shortage:
Broad direct profit control fails when the state cannot observe true costs, quality changes, replacement costs, and risk across thousands of firms in real time. The profit does not disappear; it reappears as shortage, lower quality, bribery, queuing, or black-market markup. Venezuela under the 2014 Fair Prices Law is the canonical example.
Excess-profits taxation can be efficient when it falls only on economic rent: if the profit is a windfall created by war, scarcity, monopoly position, or luck rather than by marginal effort or investment, taxing the excess does less damage. A normal return still remains. Utility-style regulation works in structural monopolies where duplicative competition is wasteful.
AI, robotics, private space, private nuclear, advanced materials, and biotech each occupy different positions in the control-frontier tradeoff space. Nuclear has high monopoly-like structure () making utility regulation defensible. AI has high network effects () making antitrust and excess-profits taxation more appropriate. Materials science at the speculative frontier () benefits most from public R&D and open science.
