POSTERS

http://www.propagandaposters.us/poster4.html Waste helps the enemies, conserve materials.

When consumers conserve materials, the demand for the new materials  in the market will drop significantly. When demand drops the producers will either produce less or they will drop the price of the materials to earn more profits form the consumers. This can cut down the resources spent on producing materials in order to channel the resources to the war.

During the world war II, these kind of posters often will affect the behaviors of consumers to carpool with others. This will cut down the demand for the resources used to ride a car such as petrol, time, space, materials to build car and so on. Subsequently these resources can also be used to channel to the war.

During world war II the army requires a lot of recruitment from the public. This kind of posters affect the behavior of people and diverge their action to join in an army. This can affect the supply and demand of the market as people, regardless whether they have comparative advantage in becoming a soldier, might waste a lot of marginal opportunity cost. Resources are not efficiently used and then subsequently increase the price of every products in the society because the society becomes poorer.

During the war time, each household is given the ration book to ration the goods such as sugar, oil and so on so that no waste is produced during the transaction. Each household needs to pledge to pay no more than the top legal price that can stand advantage against the others to get what they want. It hurts the economics even more because not everyone is there to do what they interest and what motivates them the most. The stuff and goods are not being allocated to the most needed and most valued places. It becomes destructive to the economy because it is not efficient. It does not produce the things which everyone wants in the lowest cost. Demand and supply is controlled by the central planner, and central planner cannot possibly know everything. The price of stuff might increases while the supply and demand is not increases.
