Shared White or own parking Space

After a long day at work I returned home and parked my car on my own parking space. Next morning I was again waiting on a highway during the familiar rush hour, but luckily I did not have to look for a parking space at the office, as I had my one dedicated only to me. At least, this is how it used to be. First our office parking lot was converted to a first come - first served area, and when I moved closer to the center there was no dedicated parking spaces available anymore. Did someone ask, if I want to share my parking space with my colleges? If I was paying myself for the parking space, I might have been offered a more economical shared parking lot option. If my parking lot was dedicated to me, but the cost was shared by all employees i.e. paid on the company level, what would have been my motivation to give my dedicated parking lot for common good. 

TV white space introduction has the same dilemma. The TV broadcasters, mobile, fixed, and satellite operators have their own dedicated frequency bands. The promoters of TV white space technology request them to begin to share something that has been in their own control. As the neighboring channels and physical areas are dedicated to someone, whose telephone number I know, I can contact them when I notice interference on my channels. What would motivate the current license holders to share their spectrum allocations, when they do not need them themselves? The regulators may set a policy that no other type of spectrum is available but to share the spectrum. The other option are the economical incentives. Either the use of shared spectrum should be of a lower cost or the spectrum holder should be able get additional income by allowing other users on their frequencies. Many countries will use a combination of all of these, and finding a balance between them will take some time, especially when the dedicated users are fighting for their dedicated parking spaces.
