In 1918, Young worked as an adviser on taxation and public finance to the government of Mexico.

In 1924, Young advised the Dawes Commission, which was tasked with reforming Germany's public finance. At the request of Secretary of StateCharles Evans Hughes, he began work as an economic adviser for the Reparations Commission in Paris. He served as a technical adviser to the members of the 1924 Dawes Commission, which focused on renegotiating German reparation payments. His goal was to facilitate reparation payments, while also appeasing Franco-Belgian demands following the occupation of the Ruhr. Young served as an economic adviser to help establish the Central Reserve Bank of China in 1936. He served as a permanent adviser to Chiang Kai-shekshek from 1929 to 1947.

Truman in January 1949. King Abd al-Aziz appointed him and a commission of economists to reform the budgetary and monetary systems. While Young's original plan was to create a central bank, he later drafted a charter for the creation of a currency board, the Saudi Arabian Monetary Agency, in 1952.
