The quality-quantity trade-off among Australian children

- We evaluate the adverse effect of growing family size on four measures of children's cognitive and health outcomes using Australian data.
- We utilise semi-parametric tests of quantile treatment effects to evaluate potential heterogeneity in this 'quantity-quality trade-off' across the distribution of outcomes.
- Identification is achieved through two instruments that are heavily used in the literature.
- Our results demonstrate the existence of a trade-off among Australian children, which is robust across outcome measures, but stronger for cognitive outcomes.
- The impact is uniform and affects more or less all children irrespective of their position in the outcome distribution.
