1.2.

The price of product X is reduced from $100 to $90 and, as a result, the quantity demanded increases from 50 to 60 units. Therefore, demand for X in this price range:

is elastic.

The supply of product X is perfectly inelastic if the price of X rises by:

10 percent and quantity supplied stays the same.

The greater the ease of shifting resources from product X to product Y in the production process, the greater is the elasticity of supply of product Y.

False

In which of the following instances will total revenue decline?

False

Which type of goods is most adversely affected by recessions?

Goods for which the income elasticity coefficient is relatively high and positive.

A perfectly inelastic demand curve:

For a linear demand curve:

demand is elastic at high prices.

relatively inelastic.

Compared to coffee, we would expect the cross elasticity of demand for:

Compared to coffee, we would expect the cross elasticity of demand for:

Suppose the price elasticity coefficients of demand are 1.43, 0.67, 1.11, and 0.29 for products W, X, Y, and Z respectively. A 1 percent decrease in price will increase total revenue in the case(s) of:

W and Y.

Refer to the table. Over the $10-$8 price range, the elasticity coefficient of supply is:

less than 1.

If demand for a product is elastic, the value of the price elasticity coefficient is:

greater than one.

If the demand for bacon is relatively elastic, a 10 percent decline in the price of bacon will:

increase the amount demanded by more than 10 percent.

increase the amount demanded by more than 10 percent.

the greater will be the price elasticity of demand.

In which of the following cases will total revenue increase?

Price rises and demand is inelastic.

The price elasticity of demand is generally:

negative, but the minus sign is ignored.

It takes a considerable amount of time to increase the production of pork. This implies that:

the short-run supply curve for pork is less elastic than the long-run supply curve for pork.

A cross elasticity of demand coefficient of +2.5 indicates that the two products are substitutes.

True

Antiques tend to have highly inelastic supply curves.

True

A perfectly inelastic demand schedule:

can be represented by a line parallel to the vertical axis.

Refer to the diagrams. In which case would the coefficient of cross elasticity of demand be negative?

C

Which of the following goods (with their respective income elasticity coefficients in parentheses) will most likely suffer a decline in demand during a recession?

Plasma screen and LCD TVs (+4.2)

The narrower the definition of a product:

the larger the number of substitutes and the greater the price elasticity of demand.

A manufacturer of frozen pizzas found that total revenue decreased when price was lowered from $5 to $4. It was also found that total revenue decreased when price was raised from $5 to $6. Thus,

the demand for pizza is elastic above $5 and inelastic below $5.

The supply of known Monet paintings is:

perfectly inelastic.

Refer to the diagram. If price falls from P1 to P2, total revenue will become area(s):

B + D.

The larger the positive cross elasticity coefficient of demand between products X and Y, the:

greater their substitutability.

A linear demand curve has a constant elasticity over the full range of the curve.

False

(Consider This) The supply of higher education in the United States is:

highly price inelastic.

Most demand curves are relatively elastic in the upper-left portion because the original price:

from which the percentage price change is calculated is large and the original quantity from which the percentage change in quantity is calculated is small.

Refer to the table. Over the $6-$4 price range, supply is:

inelastic.

Refer to the diagram. Between prices of $5.70 and $6.30:

D1 is more elastic than D2.

relatively price inelastic.

Suppose Aiyanna’s Pizzeria currently faces a linear demand curve and is charging a very high price per pizza and doing very little business. Aiyanna now decides to lower pizza prices by 5 percent per week for an indefinite period of time. We can expect that each successive week:

demand will become less price elastic.

If the elasticity coefficient of supply is 0.7, supply is elastic.

False

The price elasticity of demand for widgets is 0.80. Assuming no change in the demand curve for widgets, a 16 percent increase in sales implies a:

20 percent reduction in price.

Assume that a 6 percent increase in income in the economy produces a 3 percent increase in the quantity demanded of good X. The coefficient of income elasticity of demand is:

positive and therefore X is a normal good.
