Essentially all empirical questions that are addressed with sample data require estimates of sampling variance. The econometrics and statistics literatures show that these estimates depend critically on the design of the sample. The sample for the U.S. Current Population Survey (CPS), which serves as the basis for official poverty, unemployment, and earnings estimates, results from a stratified...

We present the results of three large-scale randomized controlled trials (RCTs) carried out in Chicago, testing interventions to reduce crime and dropout by changing the decision making of economically disadvantaged youth. We study a program called Becoming a Man (BAM), developed by the nonprofit Youth Guidance, in two RCTs implemented in 2009-2010 and 2013-2015. In the two studies participatio...

The conventional unitary model of household behaviour has been tested in several recent studies using, mostly, data from developed countries. These are generally based on a test of the underlying hypothesis that household members pool their income between themselves so that the household acts as a single individual. There is another hypothesis, underlying the unitary model, that each individual...

While undernutrition among children is very pervasive both in SubSaharan Africa and South Asia, child mortality is rather low in South Asia. In contrast to that Sub-Saharan African countries suffer by far the worst from high rates of child mortality. This different pattern of child mortality and undernutrition in both regions is well known, but approaches using aggregated macro data have not be...

This paper explores some difficulties encountered in multi-dimensional measures of wellbeing. In particular, it highlights the need for such indices to (i) incorporate information on individual preferences, (ii) be robust with respect to estimation assumptions given the ‘curse of dimensionality’ problem, and (iii) reflect complementarities and substitutabilities between dimensions. The paper pr...

EK Cephei (HD 206821) is a unique candidate to test predictions based on stellar evolutionary models. It is a double-lined detached eclipsing binary system with accurate absolute dimensions available and a precise determination of the metallicity. Most importantly for our work, its low mass (1.12 M⊙) component appears to be in the pre-main sequence (PMS) phase. We have produced detailed evoluti...
