Despite diminishing returns in agriculture, the production of food is not a binding constraint on growth in industrialized countries. A model is constructed in which growth is associated with a movement of labor out of agriculture and into industry, where increasing returns prevail. If the increasing returns are large enough, long-run growth can be sustained by the production of even cheaper farm machinery. However, there may be a take-off problem if the economy starts near subsistence; it may be impossible to feed workers who move into industry in the periods before their output leads to greate r food production.
