<div dir="ltr">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) <b><font color="#ff0000">we show that articles that are freely available on the internet have indeed a significantly higher citation count.</font></b><div>
