This paper finds that right after the collapse of the Soviet Union, there was “a negative productivity effect on those mathematicians whose research overlapped with that of the Soviet.” and “there is no evidence that the Soviets greatly increased the size of the “mathematics pie.””. Finally, “international differences can be explained by both differences in the size of the émigré flow into the various countries and in how connected each country is to the global market for mathematical publications.”
