[1] In 1906 Morel was secretary of a Customs Commission to examine tariff needs in a changing industrial landscape.

The committee issued a protectionist report, but the recommendations were blocked by supporters of firms that exported luxury goods.

[1] During World War I (1914–18) the Bureau d'études économiques (Office of Economic Studies) was set up in July 1915 under Morel's leadership.

The bureau contained permanent officials and parliamentarians, and was a "laboratory of ideas" for conducting economic warfare against Germany both before and after the military conflict.

[4] In 1917 a Comité d'Études was established to prepare for material on national borders for the post-war Peace Conference, and in December 1918 André Tardieu began to coordinate its work with Morel's economic committee, but he had achieved little when the peace conference began.
