Since the reform of the economic system, important changes have taken place in the distribution setup of national income in China. The proportion of individual income has markedly increased and the proportion of government fiscal revenue has markedly diminished. Inequalities of income...

Using data from COPPS/PSID, we investigate the effects of different forms and sources of income (labor, asset, welfare, and other transfers) and wealth (home equity and other wealth) on household charitable donations (total, religious, secular, combined causes, and the needy). We find that it is...

Finding the optimal size and locations for Photovoltaic (PV) units has been a major challenge for distribution system planners and researchers. In this study, a framework is proposed to integrate Geographical Information Systems (GIS), mathematical optimization, and simulation modules to obtain...

It is widely believed that happiness is strongly correlated with wealth and income, but according to the happiness–income paradox, this is not always true. The paradox predicates that there is a strong positive correlation between income and happiness nationally, but the correlation is...

The spin-polarized transport properties of nonmagnetic (metallic Al and nonmetallic C) atomic chains adsorbed on zigzag graphene nanoribbons (ZGNRs) are investigated by the density functional theory (DFT) combined with the nonequilibrium Green’s function method. We find that the spin...

Volunteer labor is generally modeled as an individualistic pursuit, akin to leisure or to human capital accumulation. Some activities labeled as volunteering, however, may be more usefully thought of as quid pro quo time commitments that are part of securing services for family members. Parents...
