Serena Henderson and Nathaniel Ostashewski have published "Barriers, Incentives, and Benefits of the Open Educational Resources (OER) Movement: An Exploration into Instructor Perspectives" in First Monday.
Here's an excerpt:
The purpose of this research was to replicate and extend Kursun, Cagiltay, and Can's (2014) Turkish study to include international participants. Kursun, et al. surveyed OpenCourseWare (OCW) faculty on their perceptions of OER barriers, incentives, and benefits. Through replication, these findings provide a glimpse into the reality of the international educators' perceptions of barriers, incentives, and benefits of OER use to assist in the creation of practical solutions and actions for both policy makers and educators alike. The results of this replication study indicate that barriers to OER include institutional policy, lack of incentives, and a need for more support and education in the creating, using, and sharing of instructional materials. A major benefit to OER identified by educators is the continued collegial atmosphere of sharing and lifelong learning.
