The June 24 edition of The Commercial Appeal reported that Shelby County Schools Superintendent Bobby Webb, who retired the following week, has been among those holding back the tide of charter schools. It also quoted county school board chairman David Pickler, who said that charter schools are still an unproven entity and that people should [b]e aware of the trend generating here.
Their reservations are not surprising, given that school choice threatens traditional public schools, but evidence suggests that more competition means better schools.
Education monopolies restrict dissatisfied parents most effective weapon: the exit option. Restrictions on competition reduce pressure on schools to perform, and students lose.
Under the current version of the Tennessee charter bill, schools must fail a federal benchmark two years in a row before students are allowed to switch to charter schools. This is two years too long. Parents should not need government permission to try to improve their kids education.
Evidence suggests that competition increases quality. In a 2008 study published in the Journal of Urban Economics, economists Keven Booker, Scott Gilpatric, Timothy Gronberg and Dennis Jansen found that Texas charter schools improved educational outcomes for students in traditional public schools.
Competition increased quality: It wasnt just students who attended charter schools who were better off. Students who remained in the traditional schools improved their test scores as well.
The authors were able to control for possible charter school cream-skimming and isolate the effect of competition on quality. This is of particular importance because one criticism of school choice is that privately operated schools will skim off the high-quality students and leave everyone else behind.
The effects the authors estimate are admittedly small, but they suggest that at the very least we can get the same quality at a lower price, or higher quality at the same price.
Webb asked whether we should allow private entities trying to get their hands on millions and millions of public dollars to operate schools.
A 2007 study of Arizona charter schools by Kerry A. King published in the Journal of Economic Issues found that students in for-profit charter schools perform no worse than students in nonprofit charter schools (she actually found higher test scores, but the differences were statistically insignificant).
If anything, taxpayers and parents should be concerned about interest groups fighting to protect their privileged access to millions and millions of public dollars.
Webb complained that charter schools take resources from traditional public schools. To borrow a phrase from economist David Friedman, however, this is a feature of charter schools, not a bug. When a private firm fails to provide what people want at prices they are willing to pay, it goes out of business (at least it should; politically powerful firms like Chrysler and GM are another story).
Resources should go from schools that dont perform up to parents expectations to schools that perform better.
Perhaps governments should subsidize education because of positive spillover benefits from basic literacy and numeracy, but this does not imply that governments should operate the schools themselves. A growing body of empirical evidence suggests that privately operated schools are more productive than government-operated schools, and we are not aware of any evidence that government-operated schools are more productive than privately operated schools.
Economist Thomas Sowell is fond of saying that there are no solutions; there are only tradeoffs. There is no way to know which tradeoffs are wise and unwise without the information that only competition provides.
Webb also asked, If its not broken, what needs to be fixed? Thats a fair question, but we shudder to think about how much progress would have been stopped if government officials could have stifled innovation and competition every time they thought something was good enough.
Pickler said charter schools are unproven, but the evidence suggests otherwise. In our opinion, the burden of proof is on opponents of choice to show that monopoly is better than competition. Memphis history of innovation deserves better. Firms that originated in Memphisfirms like Piggly Wiggly, FedEx and Holiday Innhave been trailblazers, and Memphis place in the history of American popular music speaks for itself. It would be fitting for Memphians to embrace school choice.
