Strigl's works later fell into obscurity. Mises left for Switzerland where he found a prestigious position that would allow him to write his magnum opus. Hayek, Machlup, and Haberler departed for the United Kingdom or the United States, where they could obtain academic positions foreclosed to them back home.
