If the potential employer makes an offer to a candidate and that candidate is in fact a gifted teacher, the home institution will make a counter offer. If the candidate is in fact a poor or average teacher, the home institution will not make a counter offer and the potential employer is likely to hire a poor or average teacher. This leads to what economists call “adverse selection” for job offers to potential teachers. Since the prospective employer knows it is likely to hire a poor or average teacher rather than an exceptional teacher, it does not make offers designed to attract exceptional teachers, and the market for exceptional teachers does not exist. Clearly, this problem is made worse by tenure, since tenure greatly increases the cost of making a bad hiring decision. In short, the “market for superior teaching” has unraveled due to insufficient information about teaching quality.
