The findings of Millman (1984) and Rutstein (1991) suggest that Bangladesh and Zimbabwe also may be particularly affected by this bias. In 1994-1995 both countries conducted DHS-III surveys that include the calen- dar...

Such errors resulting from sensitivity may well be compounded by errors following from recall bias in cross-sectional surveys, which...

Recent evidence indicates that gender bias—measured by using juvenile sex ratios...

Using sibling fixed-effects models to account for selection bias, we find that relative to children in other low-income families, children in SNAP-recipient households have higher average adult BMI values. However, the effects of childhood SNAP usage...
