This paper examines the change in body mass index for a cohort of Irish children as they aged from 9 to 13 and decomposes the change into parts attributable to changes in observable characteristics and changes in returns to observable characteristics. The decomposition is carried out over the...

There is a well-established socioeconomic gradient in cognitive test scores for children. This gradient emerges at very early ages and there is also some evidence that it can widen as children age. We investigate this phenomenon with two longitudinal cohorts of Irish children who take such tests...

This paper examines anonymous and non-anonymous Growth Incidence Curves (GICs) for after-tax disposable income for Ireland during its recovery period after the Great Recession, 2012-19. In the absence of suitable panel data the non-anonymous GICs were constructed on a cohort basis with cohorts...

This paper examines multidimensional poverty for three waves of a cohort of Irish children ranging from ages 9 to 17. Poverty is measured over the dimensions of health, education and family resources and both unidimensional and multidimensional poverty is examined. Both show a clear gradient...

Sequence and cluster analysis is applied to measures of body mass index for mothers and children for four waves of the Growing up in Ireland longitudinal data set. Optimal matching analysis is used to construct a dissimilarity matrix to which cluster analysis is then applied. Distinct...

The age-specific body mass index (BMI) of adult Japanese women has steadily decreased over time, while that of Japanese men has increased. This study examines the long-term trend of age-specific BMI in Japan, by combining unique historical data sets and conducting nonparametric regression...
