Artists and Curators as Authors - Competitors, Collaborators, or Teamworkers?

Dorothee Richter will question artistic and curatorial authorship and will try to place it in broader historical frame. Are artists and curators competitors at taking the grants for authorship in contemporary art? Did curators adopted the process of artistic self-organization? If they really did, what are the consequences? Are artists and curators co-workers on the field which is little undefined and more flexible and open as such?
