The fact that you might have trouble identifying it is testament to the fact that the city is blessed with an abundance of natural forested parklands.
Of course Oregon in general is a beautiful place, and as someone who relishes the gray damp wonder that is the Oregon winter, I get a lot of utility from living here. Because of my strong preference for living in Oregon, I accepted a job that payed considerably less than competing offers I had - in the most dramatic case about 50% less than what a big midwestern state university was offering.
Economists call this a compensating wage differential: the extra money you have to pay to get people to accept unpleasant jobs or the lower salaries you have to offer to people for particularly pleasant jobs. You may have to pay more then for a person who pumps septic tanks all day than someone who delivers flowers. It is a simple idea, you have to compensate people for the difference in the disutility of doing different jobs.
Politicians love to say that it is okay that salaries in Oregon's state universities are much lower than other places because of this: Oregon is such a wonderful place to live that talented academics will come anyway. There is some truth to this statement, but Oregon isn't the only place to live and the population of people like me who are willing to accept much less to be here is pretty small. For instance I was offered quite a bit more to go to a university in a lovely seaside California town - I don't suspect many would have made the decision I did. So, yes, economic theory suggests that Oregon can get away with slightly lower salaries, but there is a limit.
As I talk to some OSU students who are graduating and who have more than one job prospect, I emphasize that they should look past raw salary differentials and think hard about how much they will enjoy the work they will do in each job and ask themselves, how much is the extra pleasure of working at a particular place worth in terms of salary? What I am telling them, in other words, is figure out your personal compensating wage differential.
Good luck grads!
