Q

What are the advantages and disadvantages of the simple aggregate index?

A

Advantage:
- The method is very easy to apply

Disadvantages:
- It does NOT take into account the appropriate importance of the various commodities
- It gives greater importance to simple relatives with large bases
- The particular units in the magnitude like liters, kilos, and sacks can affect the value of the index

19
Q

A type of weighted index number where it is based on the assumption that the amount purchased by a typical family does not change from the base year amount

A

Laspeyres’ Index or Base-Year Method (LI)

20
Q

A type of weighted index number that uses quantities as weights and is convenient to use on a continuing basis since the weights remain fixed from one period to the next

A

Laspeyres’ Index or Base-Year Method (LI)

21
Q

A type of weighted index number where it requires a new set of weights every year since the quantities for year n are used as weights

A

Paasche’s Index or Current Year Method (PI)

22
Q

The weighted index number used far more often than the Paasche’s Index for measuring price changes and is larger than Paasche’s Index in general

A

Laspeyres’ Index or Base-Year Method (LI)

23
Q

The ___________ tends toward an upward bias, while ____________ tends to underestimate the true changes in price

A

Laspeyres’ Index; Paasche’s Index

24
Q

A type of weighted index number where it is a practical compromise between the use of a constant base year weights and year n by using the average of the two weights and

A

Edgeworth-Marshall’s Index (EMI)

25
Q

A type of weighted index number that is another compromise between the use of a constant base year and current period weights and combines the information summarized by the Laspeyres’ Index and Paasche’s Index by averaging them using the geometric mean

A

Fisher’s Ideal Index (FII)

26
Q

The Fisher’s Ideal Index uses which mathematical properties that make it ideal?

A
  • Time Reversal Property
  • Factor Reversal Property
27
Q

What are needed to be considered in constructing index numbers?

A
  • coverage or items to be included
  • the base or reference period to be used
  • the weights to be assigned to each item included
28
Q

What are the factors considered in the selection of items to be included?

A
  • Completeness
  • Availability of Reliable Date on the Variables
  • Quantity and Length of the Series
29
Q

The factor considered in the selection of items to be included in which all important items and variables that are necessary to compute the index number should be included and can include those items that can show the typical changes as a whole

A

Completeness

30
Q

The factor considered in the selection of items to be included in which the basic data on the variables must be reliable and should be representative of the true scenario so that the intended index number can be measured accurately

A

Availability of Reliable Data on the Variables

31
Q

The factor considered in the selection of items to be included in which a lengthy series should be examined to demonstrate characteristics and variation over time

A

Quantity and Length of the Series

32
Q

What are the factors in selecting of base period?

A
  • Time Criterion
  • Normal
  • Comparability
  • Availability of Data
33
Q

The factor in selecting of base period in which the base period must be fairly recent enough that person making the comparison can remember what conditions were like during the base period

A

Time Criterion

34
Q

The factor in selecting of base period in which the base period should in some sense be a period of normal activity for the series whose index is sought

A

Normal

35
Q

The factor in selecting of base period in which one wishes to compare one index with another and so the indexes must have the same base period

A

Comparability

36
Q

The factor in selecting of base period in which the base period should be a period for which accurate and complete data are available

A

Availability of Data

37
Q

In availability of data, the best procedure is to use what type of years as base years?

A

census years

38
Q

A measure of change in the average retail prices of goods and services commonly purchased by a particular group of people in a particular area

A

Consumer Price Index (CPI)

39
Q

The CPI of the Philippines is computed by the…

A

Philippine Statistics Authority (PSA)

40

It is a survey in which the sample households are asked the commodities and services most commonly consumed and purchased and the type of outlets where these commodities are commonly purchased or availed of and is what the market basket is based on

A

Commodity and Outlet Survey (COS)

41
Q

What are the two different income levels determined in the market basket?

A
  • the upper 70%
  • the lower 30%
42
Q

What are the four different questionnaires used for the survey of retail prices?

A

2) Survey of retail prices of processed food items, beverages and tobacco
3) Survey of retail prices of nonfood items
4) Survey or costs of fuel, light, water, house rentals, and services

43
Q

The CPI is computed using…

A

Laspeyres’ Method

45
Q

Is the minimum wage deflated by the current CPI

A

Real minimum wage rate
