I want to know the answer to the following question:
In what year did Hayek come to London?
All the background I'm provided with is that "With the help of Mises, in the late 1920s Hayek founded and served as director of the Austrian Institute for Business Cycle Research, before joining the faculty of the London School of Economics (LSE) in 1931 at the behest of Lionel Robbins.". Is that enough to answer the question?
Answer: yes
