Figure 4-5 -Refer to Figure 4-5.As price falls from PA to PB,the quantity demanded increases most along D₁; therefore,

If the price elasticity of demand is unit-elastic,a 10 per cent increase in price will result in a 10 per cent increase in revenue.

If firms do not increase their quantity supplied when price changes,then supply is

If the slope of a demand curve is equal to -0.1,then

Consider a demand curve that has a constant elasticity value of 0.What happens to quantity demanded and total revenue when price increases?

If a 5 per cent increase in income leads to a 10 per cent decrease in quantity demanded for a product,this product is

Economists estimated that the price elasticity of beer is -0.30 and the income elasticity of beer is 0.09.This means that

Last year,Joan bought 50 kilograms of hamburger when her household income was $40 000.This year,her household income was only $30 000 and Joan bought 60 kilograms of hamburger.Holding everything else constant,Joan's income elasticity of demand for hamburger is

Cross-price elasticity of demand is calculated as the

Necessities tend to have more inelastic demands than luxuries.

When the price of tortilla chips rose by 10 per cent,the quantity of tortilla chips sold fell 4 per cent,and the sale of dips (like salsa and bean dip)fell 8 per cent.This set of facts indicates that
