Establishing a quota—a limit on the number of offers that can be accepted from any one class—discriminates simply and effectively. The quota increas...

With rising oil prices, USA and many other countries have set long-term plans to electrify their transportation system and manufacture electric vehicles (EVs) to reduce their oil consumption. It is foreseen that by 2013, approximately 700,000 grid-enabled electric vehicles...
