The income elasticity of demand |
Is negative for normal goods
Is positive for normal goods
Equals the relative change in demand for a good divided by the relative change in the iincome of consumers all else being equal
Is correctly described by all of the above
|
2 |
If the income elasticity of demand is +4 |
The good is an inferior good
The good is an inelastic normal good
The good is an elastic normal good
the good is an elastic inferior good
|
3 |
The price elasticity of demand will increase with the length of the period to which the demand curve pertains because. |
Consumers incomes will increase
The demand curve will shift toward
All prices will increase over time
Consumers will be better able to find substitutes
|
4 |
The market demand for a product is found by |
Horizontally summing the individual demand curves
Vertically summing the induvial demand curves
Both horizontally and vertically summing the individual demand curve.
None of the above

The presence of substitutes for the good.
The importance of the commodity in consumers budgets
The cost of producing the commodity

The most important determinant of price elasticity is. |
The slope of the demand curve
The availability of substitutes
The price of other goods
The income of the consumer
|
8 |
An elasticity coefficient of -1 means that |
The demand curve is perfectly inelastic
The demand curve is parfectly elastic
The relative changes in price and quantity are equal
Expenditures on the good would increase if price were reduced.
|
9 |
The price elasticity of demand is teh same thing as the negative of the |
Slope
Reciprocal of slope
The first derivative of the demand function
Reciprocal of slope times the ratio of price to quantity
|
10 |
The arc elasticity formula is used to estimate elasticity when |
The product is thought to be inelastic
The product is thought to be elastic
The demand function is known
There are two observations of price and quantity
|
11 |
Price elasticity at a given price is not affected by. |
The price of complements
The price of substitutes
The consumer's income
A change in supply
|
12 |
Suppose that the price elasticity of demand for maple syrup has been estimated at-2 if quantity demanded increased by 10 precent, price must have changed by. |
5 percent lower
5 percent higher
10 percent lower
10 percent higher

A market demand curve can be derived by adding all the individual demand curves |
Vertically
Horizontally
In parallel
Any of the above as long as it is consistent
|
17 |
A price decrease and an increase in income are similar in that |
Both force the consumer to achieve a lower level of well being
Both force the consumer to reach a lower indifference curve
Both move the budget line outward
<sup>They are not similar at all</sup>
