Just price and usury
About this model
Thomas Aquinas, Summa Theologiae, 1265–1274. Goods sell at a customary just price; sellers who overcharge or lenders who take usury are fined by the Church; fines lower overcharging but also lending. A teaching model: it keeps only this core loop and leaves out everything else a real economy has.
