This paper explores inequalities in the use of modern family planning methods among married women of reproductive age (MWRA) in rural Nepal. Data from the 2012 Nepal Household Survey (HHS) were utilized, which employed a stratified, three-stage cluster design to obtain a representative sample of 9,016 households from rural Nepal. Within the sampled households, one woman of reproductive age was ...
In pig (Sus Scrofa) production, within-batch variation in bw gain of piglets during the nursery period (up to 10 wk of age) can be high and is of high economic importance. Homogeneity of BW within batches of animals is important as it influences the efficiency of use of the grower and finisher facilities, and provides an extra value for the fattening farms. In the current study, factors for a l...
This paper contributes to the discussion on the effects of the number of children on female employment in Europe. Most previous research has either (1) compared these effects across countries, assuming an exogeneity of family size; or (2) used methods that dealt with endogeneity of family size, but that focused on single countries. We combine these two approaches by taking a cross-country compa...

The first is the potential for omitted variable bias caused by the fact that fertility treatments are linked to twin births and are typically unobserved. We present estimates corrected for this bias and find...
