leukodystrophies are metabolic disorders of the brain, spinal cord and, in part, of the peripheral nerves that lead to degeneration of the white matter (myelin) of the brain. since mainly nerve tracts, which control voluntary movement, are embedded in myelin, patients with leukodystrophy suffer from progressive movement disorders and later also from mental deterioration. through a survey, we ca...

We introduce and study the extended-G geometric family of distributions, which contains as special models some important distributions such as the XTG (Xie et al. 2002) geometric, Weibull geometric, Chen (Chen 2000) geometric, Gompertz geometric, among others. This family not only includes distributions with bathtub and unimodal failure rate functions but provides a broader class of monotone fa...

We investigate partial insurance and group risk sharing in extended family networks. Our approach is based on decomposing income shocks into group aggregate and idiosyncratic components, allowing us to measure the extent to which each is insured, having accounted for public insurance programs. We apply our framework to extended family networks in the United States by exploiting the unique inter...
