Det smala egenintresset

Jag snubblar över en viktig text:

Behaviorists also argue that the summation of individual choices, in totality, cannot be relied upon to ensure the progress of mankind and the enhancement of the public good. The aggregate does not necessarily produce rationality; rather, it is more likely to result in inefficiency and inequality.6 The behaviorists maintain that forces, riding the rationale of the grail of competition, tend to warp the public good causing both inefficiency and inequality. Put simply, the public good is more than the sum of individual preferences and choices. The public good is beyond the exercise of self-interests. It is a great misunderstanding, indeed, a fallacy, to assume that people acting individually in their own self-interest can achieve the public good.7 We have known this since it was explained to us by Rousseau in 1758, as a cornerstone of democratic thought, that “personal interest is always in inverse ratio” to the common interest.8 Thus, a system where parents take public money and indulge their self-interests is highly problematic for the education policy of a state or nation.

Slutklämmen summerar diskussionen om friskolor:

Stiglitz quotes Alexis de Tocqueville who said that the main element of the “peculiar genius of American society” is “self-interest properly understood.” The last two words, “properly understood,” are the key, says Stiglitz. According to Stiglitz, everyone possesses self-interest in the “narrow sense.” This “narrow sense” with regard to educational choice is usually exercised for reasons other than educational quality, the chief reasons being race, religion, economic and social status, and similarity with persons with comparable information, biases and prejudices. But Stiglitz interprets Tocqueville’s “properly understood” to mean a much broader and more desirable and moral objective, that of “appreciating” and paying attention to everyone else’s self-interest. In other words, the common welfare is, in fact, “a precondition for one’s own ultimate well being.”17 Such commonality in the advancement of the public good is lost by the narrow self-interest. School tuition vouchers and charter schools are the operational models for implementation of the “narrow self-interest.” It is easy to recognize, but difficult to justify.

Jag har svårigheter att tolka Stiglitz.

Long-Run Benefits from Universal High-Quality Pre-Schooling

This paper investigates the role of pre-school quality for children’s cognitive development at the end of elementary schooling (age 16). We use a unique dataset based on Danish admini- strative registers where pre-school children are linked to their pre-school and its pre-school teachers. Based on this, we generate five main quality indicators of pre-schools. Child out- comes are language test scores from final (9th grade) elementary school exams. Controlling for child background factors, we find that a higher number of staff members per child, a higher share of male staff, a higher share of staff with a pedagogic education, and a higher share of teachers with non-Danish ethnic background lead to significant improvements in children’s test results in Danish at the end of the 9th grade. Boys benefit more from pre-school quality than girls. We address possible selectivity by using instrumental variables estimation. For two of the quality indicators, i.e. the share of male staff and the share of non-native staff, IV estimates show significant positive effects which are numerically higher than OLS estimates.

Min vän professorn antyder resultaten bör tolkas “varsamt”. Annars tycker jag det låter som något för kvällstidningarna.
