Mathematical Vindication of Ricardo on Machinery
用数学证明李嘉图的观点：机器可能损害工资并减少总产出。通过一个机器人例子，指出克努特·维克塞尔认为帕累托最优要求可行发明不降低总产出的观点是错误的。
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).
