During World War II, both Germany and England had plans for a paper weapon: they each printed the other's currency, with the intention of dropping large quantities by airplane, so as to increase the other's money supply. Select all of the following reasons that might have made this an effective weapon. Support for the opposing country would rise. Relative prices would become more variable. It would create additional seigniorage revenue for the country. Menu and shoeleather costs would rise. The banking system would fail. Hyperinflation could undermine the public's confidence in the economy.\

Relative prices would become more variable.

Menu and shoeleather costs would rise.

Hyperinflation could undermine the public's confidence in the economy.

Explanation:

The first reason that would make this to be effective is the hyperinflation that it will create and this is very bad for the economy as too much money will be chasing fewer goods.

Examples of what the effect of a paper money would be include: extreme hyperinflation can reduce the confidence of the public in the economy and economic policy; variability of the relative price between the countries will rise; shoeleather and menu costs will rise; it will result in an arbitrary change in tax liability; the level of uncertainty in the economy will rise and there will be an arbitrary wealth redistribution.

it should be noted this action would not deny the government seigniorage revenue from the inflation that would follow as the public will get the money dropped by the foreign airplanes.
