I think that this is a great research topic an Jennifer provides a great list of articles.
The questions is what lens you use.
From a political/legal arena you're talking about common domains and resources and how they are distributed.
Professional, government, and industry groups negotiate both what is the public interest and what role they play in it by creating codes, standards, and rules.
The institutional work perspective of Roy Suddaby, Tom Lawrence, and Bernard Leca is particularly powerful for exploring this area. Cynthia Hardy and Steve Maguire's work is focused on how actors deinstitutionalize practices for their interpretation of the public interest. My work is on how actors negotiate the meaning of contested practices to "ensure" the public interest.
My own perspective is that actors compete to define what the public's interest is and how they relate to it (work to maintain and create it).
