Write a paragraph describing how the U.S. government managed the economy during World War I and the economic effects of the management. Consider the roles played by the Food Administration, the War Industries Board (WIB), and the War Labor Board.

During World War I, the U.S. government undertook significant measures to manage the economy. The Food Administration, headed by Herbert Hoover, was established to ensure adequate food supplies for both domestic and military use. To achieve this, the administration implemented a variety of initiatives, such as promoting voluntary food conservation and urging citizens to grow "victory gardens." The War Industries Board (WIB) played a crucial role in coordinating and regulating industries that were vital to the war effort. It standardized production, allocated resources, and encouraged efficiency through the use of contracts. The War Labor Board was responsible for settling disputes between workers and employers, ensuring that workers received fair wages and working conditions. These efforts led to a significant increase in production and an improved economy overall. However, the management also resulted in some negative consequences, such as rising inflation and government control over industries, which led to concerns around the violation of free-market principles. Nevertheless, the government's economic management during World War I played a pivotal role in supporting the war effort and ensuring stability within the country.
