Which organization was responsible for regulating the U.S. economy during World War I?

The War Industries Board (WIB) was created during World War I to oversee and coordinate the production of war materials and to ensure the efficient use of resources in support of the war effort. It played a crucial role in regulating the economy by controlling industrial production and allocation of materials, setting priorities for wartime industries, and standardizing products to improve efficiency. The WIB aimed to maximize the output of war supplies and minimize waste, which was essential given the scale of the conflict.

This organization facilitated partnerships between the government and private industry, prompting businesses to convert from peacetime to wartime production. The successful functioning of the WIB illustrates how the U.S. government took a more active role in the economy during the war, ensuring that both the military and civilian needs were met despite resource constraints.

In contrast, the other organizations listed were established for different purposes: the Federal Trade Commission focused on preventing unfair business practices, the Securities and Exchange Commission was created later to regulate the stock market, and the National Labor Relations Board was established to address labor relations and protect workers' rights, particularly in the context of labor disputes.
