Question 1

i. To construct a special-purpose index designed to measure general business activity, the weights are based on the judgments of the statistician and assigned to each series. ii. The Consumer Price Index measures the change in prices of a fixed market basket of goods and services from one period to another.
iii. The CPI is not just one index, but includes a large number of groups, subgroups and selected items, such as a food index, a transportation index and a shelter index.

Accepted Answer

All statements are correct. Statement (i) describes the process of constructing a special-purpose index with weights assigned based on expert judgment. Statement (ii) accurately describes the Consumer Price Index (CPI) as a measure of price changes in a fixed basket of goods and services. Statement (iii) correctly expands on the CPI, noting it comprises various groups and subgroups, including food, transportation, and shelter indexes.

Question 2

i. To deflate sales, the actual sales are multiplied by the wholesale price index and the result multiplied by 100. ii. The CPI serves only one major function: as an economic indicator of the rate of inflation.
iii. To construct a special-purpose index designed to measure general business activity, the weights are based on the judgments of the statistician and assigned to each series.

Accepted Answer

Statement (iii) is correct as special-purpose indices often use subjective weights based on expert judgment. Statement (i) is incorrect because deflating sales typically involves dividing by a price index, not multiplying. Statement (ii) is incorrect because the CPI has multiple functions, including adjusting income payments and serving as a deflator for other economic series.

Question 3

i. The largest component of the Canadian CPI is Food. ii. Besides measuring change in the prices of goods and services, the consumer price indexes have a number of other applications. The CPI is used to determine real disposable personal income, deflate sales or other series, find the purchasing power of the dollar and establish cost of living increases.
iii. The concept of real income is sometimes called deflated income or income expressed in constant dollars and the CPI is called the deflator.

Accepted Answer

The largest component of the Canadian CPI is Shelter, not Food. Statements (ii) and (iii) correctly describe additional applications of the CPI and the concept of real income, respectively.

Question 4

Real income is computed by:

Accepted Answer

Real income is calculated by adjusting the nominal (or money) income for inflation to reflect the actual purchasing power. This is done by dividing the money income by the Consumer Price Index (CPI) and then multiplying by 100.

Question 5

i. When two or more series of index numbers to be compared do not have the same base period, we select a common base period for all series. Then we use the respective base numbers as the denominators and convert each base to the new base. ii. Canada pension plan payments and old age security pensions are periodically adjusted based on the Consumer Price Index.
iii. The largest component of the Canadian CPI is Food.

Accepted Answer

Statement (i) explains the method of converting index numbers to a common base period. Statement (ii) is correct as Canada uses the Consumer Price Index to adjust pension payments. However, statement (iii) is inaccurate as the largest component of the Canadian CPI is shelter, not food.

Question 6

i. Millions of employees in automobile, steel and other industries have their wages adjusted upward when the CPI increases. The specifics are in the management-union contracts. These clauses in the contracts are referred to as "cola clauses." ii. When two or more series of index numbers to be compared do not have the same base period, we select a common base period for all series. Then we use the respective base numbers as the denominators and convert each base to the new base.
iii. The largest component of the Canadian CPI is Food.

Accepted Answer

Statement (i) is correct as "cola clauses" are commonly included in management-union contracts to adjust employee wages based on CPI increases. Statement (ii) is correct as it is a standard practice to select a common base period for comparison when series of index numbers do not have the same base period. However, statement (iii) is incorrect as the largest component of the Canadian CPI is actually Shelter, not Food.

Question 7

i. The CPI serves only one major function: as an economic indicator of the rate of inflation. ii. To construct a special-purpose index designed to measure general business activity, the weights are based on the judgments of the statistician and assigned to each series.
iii. The Consumer Price Index measures the change in prices of a fixed market basket of goods and services from one period to another.

Accepted Answer

- Statement (i) is incorrect because the CPI has multiple functions beyond serving as an economic indicator of inflation; it is also used for indexing social security and other benefits, and for wage negotiation, among other purposes.- Statement (ii) is correct as special-purpose indices can indeed use weights based on the judgments of statisticians to measure various aspects of business activity.- Statement (iii) is correct as the CPI does measure the change in prices of a fixed market basket of goods and services over time, which is a fundamental aspect of how it tracks inflation.

Question 8

What component(s) does the CPI include?

Accepted Answer

The CPI (Consumer Price Index) includes all four components: Recreation and Education, Food, Shelter, and Clothing. Therefore, the best choice is E, which includes all of these components.

Question 9

i. Millions of employees in automobile, steel and other industries have their wages adjusted upward when the CPI increases. The specifics are in the management-union contracts. These clauses in the contracts are referred to as "cola clauses." ii. If two or more series of index numbers have the same year as the base period, then they can be compared directly.
iii. When two or more series of index numbers to be compared do not have the same base period, we select a common base period for all series. Then we use the respective base numbers as the denominators and convert each base to the new base.

Accepted Answer

All three statements are correct. Statement (i) accurately describes cost-of-living adjustments (COLAs) in contracts, which are indeed often tied to the CPI. Statements (ii) and (iii) correctly describe the principles of comparing index numbers, including the direct comparison when base years are the same and the adjustment process when base years differ.

Question 10

i. If two or more series of index numbers have the same year as the base period, then they can be compared directly. ii. When two or more series of index numbers to be compared do not have the same base period, we select a common base period for all series. Then we use the respective base numbers as the denominators and convert each base to the new base.
iii. Canada pension plan payments and old age security pensions are periodically adjusted based on the Consumer Price Index.

Accepted Answer

All three statements are correct. Statement (i) is true because having the same base period allows for direct comparison of index numbers. Statement (ii) is accurate as it describes a method for comparing series with different base periods by converting them to a common base. Statement (iii) is correct because Canada does adjust pension payments based on the Consumer Price Index to reflect changes in the cost of living.

Question 11

i. Besides measuring change in the prices of goods and services, the consumer price indexes have a number of other applications. The CPI is used to determine real disposable personal income, deflate sales or other series, find the purchasing power of the dollar and establish cost of living increases. ii. The concept of real income is sometimes called deflated income or income expressed in constant dollars and the CPI is called the deflator.
iii. To deflate sales, the actual sales are multiplied by the wholesale price index and the result multiplied by 100.

Accepted Answer

Statement (i) is correct as it lists the various applications of consumer price indexes. Statement (ii) is also correct as it explains the concept of real income and the CPI's use as a deflator. However, statement (iii) is not entirely correct as to deflate sales, the actual sales are multiplied by the consumer price index (CPI) and the result divided by 100. Therefore, only (i) and (ii) are correct statements but not (iii).

Question 12

i. Social security, old-age pensions, many apartment leases and many labor contracts are tied to the change in the CPI. ii. Millions of employees in automobile, steel and other industries have their wages adjusted upward when the CPI increases. The specifics are in the management-union contracts.

Question 18

The CPI for "personal computers and peripheral equipment" in July of 2001 was 29.3 (1982-1984 = 100). Interpret this index.

Accepted Answer

The CPI for "personal computers and peripheral equipment" in July of 2001 was 29.3 (1982-1984 = 100). This means that the price of "personal computers and peripheral equipment" in July of 2001 was 29.3 times higher than the price of "personal computers and peripheral equipment" in 1982-1984. If the average price of a computer in 1982-1984 was $879.00, then the CPI for "personal computers and peripheral equipment" would predict that the price of a computer in July 2001 would be $879.00 x 29.3 = $3,000.00.

Question 19

i. An index is a convenient way of comparing changes for different variables, i.e., average income and food prices. ii. The concept of real income is sometimes called deflated income.
iii. Purchasing power of the dollar is the same as the CPI.

Accepted Answer

Statement (i) correctly describes the use of an index for comparing variables, and statement (ii) is accurate in identifying real income as deflated income. However, statement (iii) is incorrect because the purchasing power of the dollar is not the same as the CPI. The CPI measures changes in the prices of a basket of goods and services, while purchasing power refers to the amount of goods and services that can be purchased with a unit of currency.
