Document Summary

Land, labor and capital are complements in producion: an increase in any one of the inputs leads to an increase in at least one other input. If land is ixed, then labor and capital must rise: an increase in output requires an increase in inputs, a change in the state-of-the-arts will change the input mix. Labor-saving devices make labor more producive one person can accomplish more: this lowers the per unit cost of producion and/or, expands output. Households supply labor: labor supply increases as real wages increase (wages rise faster than overall inlaion, the labor supply curve shits with paricipaion and populaion changes (e. g. , immigraion) Firms demand labor: labor demand falls as real wages increase, the labor demand curve shits with changes in producivity if producivity increases, then labor becomes more valuable. Ford has added labour-saving technologies since it began, and workers are many imes beter of today than in 1914.
