In the December 1988 issue of this Review, John Chubb and Terry Moe presented data comparing public and private schools, and made an argument concerning “politics, markets, and the organization of schools.” Chubb and Moe argue that private schools outperform public schools because they are more autonomous, advantaged by market forces rather than democratic political control. Jack Tweedie takes vigorous exception to this conclusion, arguing that the evidence does not support Chubb and Moe's conclusions about the efficacy of market forces. Dennis Riley directly attacks the virtues of market control of institutional choices in educational policy making. Chubb and Moe find their critics unconvincing.
