Differences between public and private administration can be viewed in terms of (1) constitutional arrangements, (2) the public interest, (3) markets, and (4) sovereignty. Assume for purposes of this question that you are an administrator who just left a position at a for-profit business to work in an agency of the federal government. Explain one factor in at least three of these four areas that will require you to adjust your point of view, your management style, and/or your interaction with "customers."
