In this article I analyse attitudes of academic authors toward open access and frequency of choosing open access publication venues by them. I characterize differences between authors based in the periphery countries and the core countries, with regard to choosing so called gold open access as a way of publishing academic articles. The data were obtained with an on-line survey. Emails containing links to the survey were sent to 107,296 scholars listed on the mailing lists belonging to De GruyterOpen, from December 2015 to January 2016. 1012 responses were received. Authors from the periphery countries publish their articles in gold open access more often. They also pay open access publication fees equally often as those based in the core countries. The reasons for that are complex, involving both their preference to publish in open access and the composition of publishing market in the periphery.
