In particular, if the household income is sufficiently low, only the corner solution exists and full subsidy is needed. The optimal food stamp subsidy scheme is identified and the subsidy efficiency rate is introduced to measure the impact on foo...

Recent laboratory and field experiments contradict these straightforward predictions of standard economic theory: subjects consistently make decisions that result in larger amounts going...

For the past 10 years, I have been working as an electrical engineer for Helixx, a recently established car-manufacturing company, on hybrid electric vehicles. The current project is a P2 hybrid, an expansion on the power-split hybrid model that could “provide 95 percent of the fuel efficiency benefits of an expensive two-motor system, like the one in the Toyota Prius, [a power-split hybrid], b...

Often, vaccination programs are carried out based on self-interest rather than being mandatory. Owing to the perceptions about risks associated with vaccines and the ‘herd immunity’ effect, it may provide suboptimal vaccination coverage for the population as a whole. In this case, some subsidy policies may be offered by the government to promote vaccination coverage. But, not all subsidy polici...
