The American Expeditionary Forces (A.E.F. or AEF) was a formation of the United States Army on the Western Front of World War I. The AEF was established on July 5, 1917, in France under the command of Gen. John J. Pershing. It fought alongside French Army, British Army, Canadian Army, and Australian Army units against the Imperial German Army. A minority of the AEF troops also fought alongside Italian Army units in that same year against the Austro-Hungarian Army. The AEF helped the French Army on the Western Front during the Aisne Offensive (at the Battle of Château-Thierry and Battle of Belleau Wood) in the summer of 1918, and fought its major actions in the Battle of Saint-Mihiel and the Meuse-Argonne Offensive in the latter part of 1918.

However, the supply shocks can be negative and positive. The negative supply shocks represent the shortages of the commodity. The sudden fall in production increases the price of commodity.
