International Remittances – A proposal how to test hypotheses about determinants of remittances with macroeconomic time series

We study the determinants of remittances to developing countries at different time horizons. Remittances to developing countries nowadays exceed official development assistance and constitute a significant fraction of the disposable income of many households in developing countries. Different hypotheses suggest that remittances are often sent to compensate for low incomes, which may impose a downw

Explicit local exchange-correlation potentials

The possibilities of the Hohenberg-Kohn-Sham local density theory are explored in view of recent advances in the theory of the interacting electron gas. The authors discuss and provide numerical data for the effective exchange-correlation potentials μxc for ground state problems and Vxc for excitation spectra. The potential μxc(r) is written as a factor β(ρ(r)), which depends on the local density
