Although open access has steadily developed with the continuous increase in subscription journal price, the effect of open access articles on citations remains a controversial issue. The present study empirically examines the factors determining authors’ choice to provide open access and the effects of open access on downloads and citations in hybrid journals.
This study estimates author’s choice of open access using a probit model, and the results show that the cost of open access is an important factor in the decision. After a test for endogeneity of open access choice, the equation for downloads is estimated with the variables representing characteristics of articles and authors.
The results of estimating downloads by ordinary least squares show that open access increases the number of downloads in hybrid journals. On the other hand, from citation estimations using a negative binominal model, this study found that the effect of open access on the number of citations differs among hybrid journals.
It is a good practice for authors to consider a balance between article processing charges and the benefits that will be gained from open access when deciding whether to provide open access.
