Although the theoretical trade-off between the quantity and quality of children is well-established, empirical evidence supporting such a causal relationship - particularly on child health - is limited. We use two measures of child health to asses the quantity-quality trade-off across the entire...

Although the theoretical trade-off between the quantity and quality of children is well established, empirical evidence supporting such a causal relationship is limited. This chapter applies a recently developed nonparametric estimator of the conditional local average treatment effect to assess...

It is difficult to detect the inner layer of the bimetallic tube and to describe its full-cross-section deformation, which affects its verification and utility negatively. To tackle this issue, a novel theory is proposed for fitting the full-cross-section deformation characterization of Cu/Al...
