Nucleon structure from 2+1-flavor domain-wall QCD

Nucleon-structure calculations of isovector vector- and axialvector-current form factors, transversity and scalar charge, and quark momentum and helicity fractions are reported from two recent 2+1-flavor dynamical domain-wall fermions lattice-QCD ensembles generated jointly by the RIKEN-BNL-Columbia and UKQCD Collaborations with Iwasaki $\times$ dislocation-suppressing-determinatn-ratio gauge action at inverse lattice spacing of 1.378(7) GeV and pion mass values of 249.4(3) and 172.3(3) MeV.Comment: 8 pages, 6 figure, a talk presented at the 35th International Symposium on Lattice Field Theory "Lattice 2017'

Emigration and wage inequality in a dual economy

We examine the effect of emigration of skilled and unskilled labor on pre-existing wage gap between the skilled-unskilled labor. The results by Marjit and Kar (2005) will be confirmed also in a dual economy setup.International factor mobility, Wage inequality, Unemployment, Harris-Todaro model

Emigration promotion and urban unemployment

Unemployment is present in many developing countries. Thus, the government of a country that suffers from chronic unemployment often wants to emigrate some workers to foreign countries. This paper investigates whether such a policy is successful for reducing domestic unemployment.Unemployment; Emigration; Harris-Todaro model
