A great deal of the debate surrounding public sector unions focus on how much public employees earn versus private workers. Every credible analysis – those that account for huge differences between public and private workers in terms of characteristics like profession, education, and experience – find that public compensation is competitive or lower than that of private-sector workers (for recent examples, see here, here, and here, or a review here).
I have, however, heard a few thoughtful observers make the point that virtually all these analyses include education workers, and that this might be a little misleading. It’s a fair point. Roughly one in five state/local government employees are in fact K-12 teachers, while another five percent are professors at public colleges and universities. This is important because analyses of public/private sector compensation essentially compare public employees with workers with similar characteristics (education being the most important one) in the private sector. The research above indicates that workers with more education pay a larger “price” for working in the public sector, whereas many lesser credentialed, lower-skilled government jobs actually pay more. Since many teachers have master’s degrees (and professors Ph.D.’s), and they are such a huge group, it’s reasonable to wonder if they might be skewing the overall estimates.
So, I decided to see if a comparison of public/private compensation that does not include teachers and professors would yield very different results. Let’s take a look.
