the income effect
when the price of a product rises, consumers shift their purchases to other products whose prices are now relatively lower. This statement describes:
the substitution effect
the construction of demand and supply curves assumes that the primary variable influencing decisions to produce and purchase goods is.:
the demand curve for a product might shift as the result of a change in
consumer tastes, consumer incomes, & the prices of related goods
when an economist says that the demand for a product has increased, this means that:
consumers are now willing to purchase more or theis product at each possible price.
the law of supply indicates that
producers will offer more of a product at high prices than they will at low prices
