Miguel Ferreira et. al. has published their experiences of University of Minho institutional repository in their paper "Carrots and Sticks: Some Ideas on How to Create a Successful Institutional Repository" in January/February 2008 issue of D-Lib Magazine. According to them - development of a successful repository requires "an adequate promotional plan, development of value-added services for authors, engagement in the international community and definition of a self-archiving mandate policy". I feel value added services are more important in motivating authors to deposit their publications. Institutional repositories can take clue from services like Slideshare.net. It is a platform where people can upload and share their presentations (PPTs). Value additions like Most Viewed (currently or by varied period duration), Most Downloaded, Most favorites, Number of times a presentation has been viewed and downloaded are wonderful ploys that not only motivates authors but also help viewers to browse through collection. It also allows the visitors to mark a presentation as favorite, tag it and leave comments as well.
