Mathematical Vindication of Ricardo on Machinery
Ricardo is shown to be right that machinery can hurt wages and reduce output. A dramatic robot example reveals Knut Wicksell's erro r in believing that Pareto optimality calls for no drop in total outp ut from a viable invention. Under Ricardo's axiom that labor supply a djusts to keep wages at the subsistence level, he can correctly deduc e on a market-clearing basis a rise in his net product (rent plus int erest), while the greater drop in population and total wages results in a reduction in his gross product (rent plus interest plus wages).
