Opening the Black Box

Controversy over the aggregate impact of foreign aid has focused on reduced form estimates of the aid-growth link. The causal chain, through which aid affects developmental outcomes including growth, has received much less attention. We address this gap by: (i) specifying a structural model of the main relationships; (ii) estimating the impact of aid on a range of final and intermediate outcome...

Silver Isotope Fractionation in Chondrites

I n t r o d u c t i o n : The study of Ag isotopic compositions is of particular interest because of the extinct radionuclide Pd, which decays to Ag with a half-life of 6.5 Myrs. This chronometer has been successfully applied to unravel formation and differentiation processes of iron meteorites [1-3]. Compared to the early measurements by TIMS, the use of multi-collector inductively coupled pla...
