AD VALOREM TARIFF: A tax on imports that is specified as a percentage of the value of the good or service being taxed. This is one form of trade barrier that's intended to restrict imports into a country. Unlike nontariff barriers and quotas, which increase prices and thus revenue received by domestic producers, an 'ad valorem tariff' generates revenue for the government. For example: a 15 percent ad valorem tariff on a TV set worth $100 would pay a tariff of $15. One advantage of an ad valorem tariff is that it keeps up with changes in prices (mostly inflation).

DEMAND INCREASE AND SUPPLY DECREASE: A simultaneous increase in the willingness and ability of buyers to purchase a good at the existing price, illustrated by a rightward shift of the demand curve, and a decrease in the willingness and ability of sellers to sell a good at the existing price, illustrated by a leftward shift of the supply curve. When combined, both shifts result in an indeterminant change in equilibrium quantity and an increase in equilibrium price.
