9.1 War Industries and Economic Mobilization

World War I transformed America's economy, turning the nation into a global industrial powerhouse. The war created massive demand for goods, spurring rapid growth in manufacturing, agriculture, and technology. This economic boom reshaped American society and set the stage for the Roaring Twenties.

The government played a crucial role in mobilizing the economy for war. Centralized planning, financial management, and propaganda campaigns coordinated industrial production and public support. These efforts had lasting impacts on American business and laid the groundwork for future economic policies.

1 of 3

• World War I catalyzed rapid industrial growth and economic expansion in the United States transformed the nation from a debtor to a creditor country
• The war created unprecedented demand for American goods led to a significant increase in exports
  • Agricultural products (wheat, corn)

  • Inflation rates reached up to 20% during the war years
  • Post-war recession occurred as demand for goods decreased and soldiers returned to the workforce

Government Mobilization for War

Centralized Economic Planning

• The government implemented a centralized economic planning system coordinated industrial production and resource allocation
• The War Industries Board set production priorities, allocated scarce resources, and standardized military goods
  • Prioritized steel production for shipbuilding and armaments

• The Food Administration managed food production and distribution
  • Encouraged food conservation ("Meatless Mondays", "Wheatless Wednesdays")
  • Increased agricultural output through improved farming techniques and expanded acreage

Financial and Manpower Management

• The Federal Reserve System played a crucial role in financing the war effort
  • Facilitated the sale of Liberty Bonds to the public
  • Adjusted monetary policy to support war-related economic activities
• The Selective Service Act of 1917 managed the draft and ensured a steady supply of manpower
