[Irtalk] Do open access articles in economics have a citation advantage? - Munich Personal RePEc Archive

[Hilton Gibson]

We investigate whether articles in economics that are freely available on
the web have a citation advantage over articles with a gated access. Our
sample consists of articles from 2005 from 13 economic journals (including
the top five journals). In addition to standard mean comparisons we also
use a negative-binomial regression model with several covariates to control
for potential selection effects and quality bias. Using citation data from
three different databases (Web of Science, RePEc and Google Scholar) *we
show that articles that are freely available on the internet have indeed a
significantly higher citation count.*
