Question 6

Four sources of bias in the CPI may lead to it overstating the inflation rate

Question 7

measuring inflation

The producer price index (PPI):

Answer 7

§: An average of the prices received by producers of goods and services at all stages of the production process.
§Like the CPI, the PPI tracks the prices of a market basket of goods.

Question 8

calculate the inflation rate

Answer 8

CPI = expenditures in current yr/ expenditures in base yr x 100

CPI in 2011 = 314/314 x 100 = 100

CPI in 2015= 360/314 x 100 = 114.65

Inflation rate = CPI in current yr- CPI in base yr/ 100 x 100 = 114.65-100/100 x 100=

Question 38

4 biases that cause changes in the CPI to overstate the true inflation rate

Answer 38

1. Substitution bias 2. quality bias 3. new product bias: 4. outlet bias

Question 39

describe substitution bias

Answer 39

The substitution bias is a weakness in the Consumer Price Index that overstates inflation because it does not account for the substitution effect, when consumers choose to substitute one good for another after its price becomes cheaper than the good they normally buy. they likely substitute away from items that get disproportionately expensive to goods that got comparatively less expensive.

Question 40

describe quality bias

Answer 40

price from increase in quality overtime technological advancement increases the life and usefulness of products. CPI does not reflect this product improvements are under-counted) For example, an average computer today might cost about the same as an an average computer cost last year, but today's computer is better than last year's computer in a number of ways that the CPI doesn't account for.

Question 41

what is new product bias

Question 42

what is new product bias

Answer 42

new products are not introduced in the index until they become commonplace (new products are not counted for a while after the appear)

Question 43

what is outlet bias

Answer 43

the consumer shift to new outlets such as wholesale clubs and online retailers

Question 44

a severe drought reduces the production of tropical fruit, causing the price of tropical fruit to rise significantly

Answer 44

overestimate, substittion bias, becoming consumers would substitute cheaper foods for tropical fruit

Question 45

new tech signiicantly decreases the price of 3D televisions

Answer 45

accurately reflects a fall in price of consumer goods

Question 46

consumers switch to buying front loadin clothes washing machines instead of the less water efficient top-loading washing machines, even though the front loading washing machines are more expensive

Answer 46

overestimate, similar to new product bias or quality bias

Question 47

Both the inability of the CPI to incorporate technological progress and its failure to account for substitution in consumption decisions imply that, in most cases,

Answer 47

the Consumer Price Index likely overstates increases in the cost of living that households actually feel.
