What were two ways that countries used economic policies to control the cost of World War 1?

Countries implemented various economic policies during World War I to manage war costs, primarily through the introduction of war bonds and taxes. War bonds were sold to finance military expenditures, encouraging citizens to invest in their nation's efforts while also promoting a sense of patriotism. Additionally, governments increased taxes, particularly on profits and luxury goods, to generate revenue and reduce inflationary pressures. These measures helped manage national debt and stabilize economies during the conflict.
