A few years ago, Jerry Hausman showed that Wal-Mart does a lot to benefit even consumers who don’t shop there. When a Wal-Mart opens, competitor local supermarkets cut their prices to keep customers. And poor customers reap most of the benefits.
Suppose your worry about school vouchers is that low social capital parents’ stick with a local underperforming school while kids whose parents have better social capital all flee with their vouchers to the better private schools. And suppose further that you care way more about the potential losses to the former than about the gains for the latter. You might then oppose voucher systems.
Figlio and Hart show that public schools facing competitive pressure from private schools under a new voucher system provided stronger student score improvements. All that concern about kids left behind as the private schools cream off the best voucher kids? Not much of an issue if the public schools facing the competitive pressures perform better as consequence. They find the biggest positive effects in public schools facing strong financial incentives to retain low-income students.
There has also been studies showing that charter schools not only improve the performance of students at those schools, but neighbouring public schools improve their performance also.
For some strange reason, this is seen as a bad thing because it clashes with an ideology that competition is bad.Tags: charter schools, Eric Crampton, vouchers
