| Summary/Abstract |
The general goal of the present study is to analyze whether children with siblings lag behind their only-child counterparts in terms of health and nutrition, cognition and educational performance, and non-cognitive outcomes. We draw on a dataset containing 25 871 observations constructed from three school-level surveys spanning four provinces in China. The analysis compares children with siblings and only children aged 9 to 14 years old in terms of eight different health, cognitive and non-cognitive indicators. We find that with the exception of the anemia rate, health outcomes of children with siblings are statistically indistinguishable from those of only children. In terms of cognition, children with siblings performed better than only children. Moreover, outcomes of children with siblings are statistically indistinguishable from those of only children in terms of the non-cognitive outcomes provided by measures of anxiety. According to our results, the same general findings are true regardless of whether the difference between children with and without siblings is disaggregated by gender.

| Summary/Abstract |
There is a great degree of heterogeneity among the studies that investigate whether computer technologies improve education and how students benefit from them – if at all. The overall goal of this study is to assess the effectiveness of computing technologies to raise educational performance and non-cognitive outcomes and identify what program components are most effective in doing so. To achieve this aim we pool the data sets of five separate studies about computer technology programs that include observations of 16,856 students from 171 primary schools across three provinces in China. We find that overall computing technologies have positive and significant impacts on student academic achievement in both math and in Chinese. The programs are found to be more effective if they are implemented out-of-school, avoiding what appear to be substitution effects when programs are run during school. The programs also have heterogeneous effects by gender. Specifically, boys gain more than girls in Chinese. We did not find heterogeneous effects by student initial achievement levels. We also found that the programs that help students learn math—but not Chinese—have positive impacts on student self-efficacy.
