The home front in the First World War: workers, supplies and output

About this model

This is a teaching model of one European home-front economy during the First World War, not of the battlefield. A fixed workforce is split between factories and agriculture, imported raw materials arrive each month minus a random loss to submarine warfare, and the population eats from a food stock. On the Scenarios stage, move the Lever "Factory worker share" and watch what happens to the food stock after 36 months. The numbers are illustrative.
