Abstract: This paper uses a unique data set of Mexican researchers to 
explore the determinants of research output and impact. Our findings 
confirm a quadratic relationship between age and the number of published 
papers. However, publishing peaks when researchers are approximately 53 
years old, 5 or 10 years later than what prior studies have shown. 
Overall, the results suggest that age does not have a substantial 
influence on research output and impact. We also find that reputation 
matters for the number of citations but not publications. Results also 
show important heterogeneity across areas of knowledge. Interpretations of 
other aspects, such as gender, country of PhD, and cohort effect, among 
others, are also discussed. (C) 2007 Elsevier B.V. All rights reserved.
