Economist (UMass Amherst) with a peer-reviewed research program on selection effects in Soviet/Russian scientist emigration, including "Who Leaves and Who Stays? Evidence on Immigrant Selection from the Collapse of Soviet Science" (in Aldo Geuna, ed., Global Mobility of Research Scientists, Elsevier, 2015) — reported via search-engine synthesis only to find that the most-skilled scientists left earliest in the transition period, a finding that would bear directly on the vault's open "elite left first" question. That chapter is paywalled and unread by the vault; a related open-access 2013 working paper on PhD-production effects after Soviet collapse was fetched in full but addresses a different question (human-capital formation, not career-premium selection). Currently the strongest identified candidate for independent corroboration or refutation of Pronskikh's structural thesis.
