Abstract: Using a panel of individual researchers at the KU Leuven, Belgium, we 
analyze the impact of a range of productivity drivers on research performance 
at the separate quantiles of the productivity distribution. We estimate a 
correlated random-effects quantile regression model, accounting for 
unobserved heterogeneity of researchers and applicable to count data. We find 
that the effect of most regressors, particularly system-factors incentivizing 
researchers (like promotion record and access to research resources), as well 
as the gender of the researcher differ significantly at different points in the 
distribution, yielding strong support for our quantile regression approach. 
Comparing publications versus citations as dimensions of research performance, 
we find the incentive factors to work stronger in affecting research quality. 
Finally, the split-sample regression results emphasize the heterogeneity across 
scientific disciplines.
