Which оf the fоllоwing stаtement(s) is not true? I. In the United Stаtes, educаtion is primarily provided by state and local governments, and only a small share of students go to private schools. II. Negative externalities, success in credit markets, and failures of family utility maximization, are rationales for public intervention in education. III. Vouchers might solve the crowd-out problem provided by a free education, by allowing people to choose the optimal level of education for themselves, as well as interjecting competition in the education market. IV. Existing evidence suggests that private school choice through vouchers can move students to better schools, but a more comprehensive evaluation of the total social effects of vouchers is needed before policy conclusions can be drawn.
