Estimating Dark Matter Distributions
Thanks to instrumental advances, new, very large kinematic datasets for nearby dwarf spheroidal (dSph) galaxies are on the horizon. A key aim of these datasets is to help determine the distribution of dark matter in these galaxies. Past analyses have generally relied on specific dynamical models or highly restrictive dynamical assumptions. We describe a new, non-parametric analysis of the kinem...
متن کاملWelfare Measures with Risk: Do Distributions Matter?
Mortality risks from exposure to many common environmental contaminants are often difficult to know with certainty, leading some people to form different perceptions of those risks. Recent work by Hurley and Shogren (2005) and Hill, Perry and Willis (2005) suggest that subjects often base their assessment of uncertain risks on the mode, rather than the mean, of the distribution pertaining to th...
متن کاملInstitutions Matter, but Which Ones?
In the last two decades institutional economics of development has been enriched by historical and, more recently, quantitative analysis of the effects of the quality of institutions on the pace and pattern of economic development. Following the leadership of Douglass North, this literature has shown how important secure property rights are in encouraging investment and innovations, allowing fo...
متن کاملWe Prefer Sons But Does It Matter
Highly imbalanced sex ratios suggest that Asian families prefer sons. This preference may be expressed as reduction in parental investment in daughters when a younger son is born. This study investigates the gender effect of a younger sibling on older daughter's schooling. We construct a unique dataset linking national administrative data on college entrance examinations (CET) to birth registry...
متن کامل0 . 1 Which distributions of matter diffract ? – Some answers
This review revolves around the question which general distribution of scatterers (in a Euclidean space) results in a pure point diffraction spectrum. Firstly, we treat mathematical diffration theory and state conditions under which such a distribution has pure point diffraction. We explain how a cut and project scheme naturally appears in this context and then turn our attention to the special...
