This is the children quantity-quality trade-off in family support of elderly parents.
This is in line with the children quantity-quality trade-off rule (Wu 2012; Ye and Wu 2011).
According to Becker's "children quantity-quality tradeoff model," there is a positive relationship between family income and fertility as income increases, the demand for children increases, and so does the demand for the quality of children.
In Sato's formulation, the higher wages in larger, more expensive cities could induce women to substitute more market work for less household work, and possibly away from child quantity and more towards child quality.
However, the substitution effect dominates the income effect under the usual assumption that parents with higher income prefer to invest more in each child (quantity-quality tradeoff).
This dimension is designed to adapt to the precision of the children's quantity representation, and to push children to progressively increase this precision.
Our comparison task included varying levels of numerical distance, thus allowing the software to adapt to the current level of precision of the child's quantity representation.
In baby foods for infants and young children, the quantities of total carbohydrate shall not exceed 10 g/100 ml for vegetable juices and drinks based on them, 15 g/100 ml for fruit juices, nectars and drinks based on them, 20 g/100 g for fruit-only dishes, 25 g/100 g for desserts and puddings and 5 g/100 g for other non-milk-based drinks.
Both intervention and control group children consumed similar quantity of milk, and milk in both groups was iso-energic, with identical macronutrient quality and quantity as well as quantity of vitamins and minerals.
