Note: The dependent variable is a binary variable that takes on a value one in the year we observe the elite scientist moving to a new academic position located within 50 miles. Moves up or down are based on a ranking of institutions by percentiles of total NIH funding received (per grantee). The sample includes scientists who moved to an institution that was 10 percentiles or more higher (lower) in the ranking of NIH funding and scientists who did not move. This means that scientists who moved to an institution that was less than 10 percentiles different (i.e. lateral movers) and scientists who moved down (up) are excluded. Estimation is by logit and marginal effects are reported. All regressions include full age, vintage category, and year fixed effects and controls for percentile of origin institution. Robust standard errors are in parentheses, clustered at the individual level. See Section III for a full description of how the sample and variables were constructed.
