In this study, we use the UK Millennium Cohort Study to estimate a dynamic factor model of child development. Our model follows the children from birth until 7 years of age and allows for both cognitive and noncognitive abilities in children. We find a significant self-productivity effect in both cognitive and noncognitive development, as well as some evidence of dynamic dependence across different abilities. The activities that parents carry out with children at home (parental investment) have a significant effect on children's development; we find substantial evidence of two distinct latent parental investment variables with differential effects across the two abilities.
在本研究中,我们使用英国千禧世代研究来估计儿童发展的动态因素模型。我们的模型追踪儿童从出生到7岁的情况,并考虑了儿童的认知和非认知能力。我们发现认知和非认知发展中都存在显著的自我生产力效应,以及不同能力之间动态依赖的一些证据。父母在家中与孩子一起进行的活动(父母投入)对孩子的发展有显著影响;我们发现有大量证据表明存在两个不同的潜在父母投入变量,它们对两种能力有不同的影响。
