Rappard was deeply involved in both the practical administration of mandate territories and the development of neoliberalism. He was a close friend of Hayek, who wrote to him in the wake of the success of The Road to Serfdom that 'there are still many more people who feel on the whole as we do than I had ever dared hope'. As the co-founder of the Graduate Institute of International Studies in Geneva, Rappard provided a wartime institutional home to a group of neoliberal thinkers that included Ludwig von Mises, Wilhelm Röpke and Luigi Einaudi.
