Economics of School Choice via Ray Perryman. The Intel Byte to Cogitate:

The operating expenses of a school, roughly $9000 per student, do not decrease by $9,000 if a student leaves the school.

In Ray Perryman words “Thus, the funding that follows a student can have a proportionally larger impact on the public school left behind, depending on the amount of that funding.”
