Our study examines factors affecting children's cognitive ability in Vietnam for the period 2006–2016. We find that conditional wealth has a positive association with the cognitive capacity of 15-year-old children, manifested in all three methods of measurement: vocabulary points, math scores and reading comprehension scores in Vietnamese. Notably, the finding implies that improving household wealth after the children's first 1,000 days still plays an important role in the cognitive development of 5–12-year-olds. Also, it suggests that using conditional wealth enables us to capture the impact of economic shocks, thereby having a significant effect on the cognitive ability of children.

更大的家庭财富是否会让年幼的孩子表现更好？越南的情况

我们的研究调查了 2006 年至 2016 年期间影响越南儿童认知能力的因素。我们发现条件财富与 15 岁儿童的认知能力呈正相关，表现在所有三种测量方法中：越南语词汇分数、数学分数和阅读理解分数。值得注意的是，这一发现表明，在孩子出生 1000 天后改善家庭财富仍然对 5-12 岁儿童的认知发展起着重要作用。此外，它还表明，使用有条件的财富使我们能够捕捉经济冲击的影响，从而对儿童的认知能力产生重大影响。
