利用博洛尼亚日托系统的入院阈值，我们使用回归不连续（RD）设计表明，在相对富裕的人群中，0-2岁儿童多一个日托月会使8-14岁儿童的智商降低0.5%（标准差的4.7%）。这种负面影响的程度随着家庭收入的增加而增加。人格特质也有类似的负面影响。这些发现与心理学的假设一致，即日托中心的儿童与成年人一对一的互动较少，这种互动质量较高的家庭会产生负面影响。我们将这个假设嵌入到一个模型中，这个模型为我们的研发设计提供了结构。
Exploiting admission thresholds to the Bologna day care system, we show using a regression discontinuity (RD) design that one additional day care month at age 0-2 reduces intelligence quotient by 0.5% (4.7% of a standard deviation) at age 8-14 in a relatively affluent population. The magnitude of this negative effect increases with family income. Similar negative impacts are found for personality traits. These findings are consistent with the hypothesis from psychology that children in day care experience fewer one-to-one interactions with adults, with negative effects in families where such interactions are of higher quality. We embed this hypothesis in a model that lends structure to our RD design.
