A. Gross domestic product
as defined for ICP-purposes
- The ICP, from the beginning, has
focused on comparisons of gross domestic product from the expenditure side.
GDP is a basic concept in the United Nations System of National Accounts
(SNA). Most participating countries base their national accounting system
on the recommendations of the SNA, and the SNA gives a detailed description
of the content of the gross domestic product. Therefore, the basic conditions
in respect of the comparability of this concept are relatively easy to
meet by participating countries. Nevertheless, country practices may differ
to some extent from international recommendations and, if these differences
are not recognized and corrected, they could lead to incompatibilities
in the ICP results. Therefore, a thorough scrutiny of the content of GDP
is required.
- As the present Handbook is prepared,
the 1968 SNA, the so-called Blue Book, is being revised. At this stage,
most of the recommendations for the revised SNA are known, though they
will not be formally considered by the Statistical Commission until 1993.
Where no special mention is made, it may be assumed that references in
this chapter refer to both the old and the new SNA. Where changes recommended
for the new SNA are likely to be accepted, as in the case of health and
education expenditures, references will be to the new system. Where the
final outcome is uncertain, this will be indicated in the text.
- For the ICP, GDP is compared across
countries by expenditure category breakdowns, that is, household consumption,
government, capital formation and net exports. The principles on which
the accounts are sectored are discussed in part I of this section, while
the four sectors are discussed in parts 2 to 5. This section concludes
with a discussion of the timing of the collection of expenditures, while
sections B and C treat other expenditure aggregates and the basic expenditure
headings.
1. Sectoring of the
expenditure accounts
- Four basic sets of expenditure data
are necessary for the ICP: household consumption, government, capital formation
and net exports. Under the 1968 SNA, the coverage in household consumption
could vary from country to country because of differing institutional relationships,
especially as they applied to health and education. Largely as a result
of the ICP work, an alternative presentation of consumption will be introduced
in the new SNA.
- The basic distinction that the new
SNA introduces is between consumption expenditures and actual consumption.
This is illustrated in the diagram below:
|
Consumption
expenditures |
Actual
consumption |
of households |
of government |
Individual consumption |
IC |
TC |
Households = IC + TC |
Collective consumption |
|
CC |
Government = CC |
Consumption expenditures |
IC |
CC + TC |
IC + CC + TC |
In this tableau, IC represents individual
consumption purchased by households, TC represents individual consumption
of households that is purchased or financed by government and CC is collective
consumption of government purchased by government. In the ICP, then, household
consumption is actual consumption of households.
- Non-profit institutions will continue
to be a separate sector in the new SNA. In principle, actual consumption
of households for the ICP should include expenditures by non-profit institutions,
such as for education, under the headings where they are actually consumed.
2. Household consumption
- Household consumption, as defined in the ICP and
in the proposed new SNA concept of "actual total consumption of households" consists
of:
- Goods and services purchased
by households;
- Goods produced by households
for their own consumption or received as remuneration in kind;
- Goods and services accruing
to households free of charge or at a substantially reduced rate,
financed by
government or non-profit institutions serving households.
- Items (a) and (b) above were also
covered by the household consumption expenditure concept of the 1968 SNA.
However, the third item, goods and services accruing to households free
of charge or at a very reduced rate, was either included in the final consumption
of the financing sector (government or non-profit institutions serving
households) or was missing entirely from the gross domestic product. As
mentioned above, the 1968 SNA does not have a concept of actual consumption
of households (or, in earlier terminology, total consumption of the population).
- Some consumption boundaries
- Goods and services purchased by households
should cover everything that households buy, if these items are designed
for consumption. Goods purchased by households primarily for use in production
(e.g., tools purchased by members of households to be used in an unincorporated
enterprise owned by them) should be excluded from household consumption
and should be treated as intermediate consumption. In principle, also,
goods that are used both for consumption and production purposes, for example,
a physician's car, which is used for both private and business purposes,
should be apportioned between household consumption and intermediate consumption
according to estimated use.
- Purchases of household durable goods
(such as television sets, cars) should be included in household consumption
of the accounting year in which they are purchased, in spite of the fact
that these goods serve consumption purposes over several years and may
also be paid for in installments over several years. Dwellings and similar
structures (such as holiday homes) are the only exceptions; they have to
be treated as capital formation of the period when they are purchased.
For these items, consumption of the reference period consists of the imputed
rent, that is, the rent the household would pay for the same dwelling if
it was rented rather than owned.
- Household consumption is the consumption
of resident households (as opposed to the consumption of resident and non-resident
households on the domestic market). Thus, purchases of goods and services
abroad by resident households are included, and purchases by non-resident
households (e.g., by foreign tourists) on the resident market are excluded.
In general, as a first step in the calculation of the consumption of resident
households, the consumption on the domestic market is determined (since
no distinction can be made at the point of purchase as to whether the customer
is resident or not), and as a second step the estimated amount of the purchases
of resident 'households abroad is added and the estimated amount of the
purchases of non-residents on the domestic market is deducted. (However,
this is generally done only at the level of total household consumption.)
- Consumption of goods and services
connected with business travel expenses is treated as intermediate consumption
and excluded from household consumption.
- Interest payments by households on
borrowed funds or for consumer credit (installment) payments are treated
as transfers and excluded from household consumption. However, household
consumption includes payments for financial services of banks to households
for credit cards, checking accounts and so on. The new SNA will recommend
that a charge be included in household consumption for the imputed service
charge of financial intermediaries.
- The net difference between consumer
spending and winnings on lotteries or other legalized gambling are also
included in household consumption. For non-life insurance, the difference
between insurance premiums paid and claims received by households is included
in household consumption as representing a purchase of insurance services.
- Purchased consumption is to be valued
at the prices actually paid by the households. Thus, taxes (sales, excise,
value added) and delivery costs are included in household consumption.
Similarly, if the purchase price represents a reduction from the regular
price, because of a sale or discount, it is the purchase price that should
be used. Any interest charges resulting from late payment, as for example
with credit card purchases, are not included in the price.
- Consumption from own production by
households (e.g., potatoes, fruits, meat produced by farmers and consumed
by the same households) are valued at producer prices, that is, at prices
the households would receive if these products were sold at the nearest
market point. Processed own-produced products should be valued at the prices
of the processed products (e.g., as butter and cheese and not as milk);
however, this value should exclude the results of the service-type activities
carried out within the households (e.g., value created by cooking). As
already mentioned, the consumption of own dwellings should be valued at
imputed rents.
- When employers buy goods to supply
to their employees, these goods are to be valued at the cost to the employer,
as in the case, for example, of food consumed by members of the armed forces.
If the employer provides workers products of the firm itself, they are
to be valued at those prices at which such products could be sold by the
firm. Uniforms supplied by employers should be included in household consumption
only if it is usual to also wear them off duty.
- Consumption financed by other
sectors
- In earlier phases of the ICP, allocating
all medical and education expenditures to household consumption was presented
as a departure from the rules of the SNA. As discussed above, with the
introduction in the new SNA of the concept of actual consumption in addition
to the concept of consumption expenditures, this difference in presentation
between the ICP and the SNA will disappear.
- The concept "goods and services accruing
to households financed by other sectors" needs some elaboration. In particular,
the following should be made clear:
- What kind of goods and services
are involved;
- How the consumption of these goods
and services should be determined;
- What the term "other sectors" means;
- How those cases are to be treated
where the financing of the expenses is shared by households and other
sectors.
- As to the kind of goods and services
involved, not all goods and services financed by other sectors should be
allocated to actual household consumption. Only those goods and services
that are consumed by individuals (explicitly) rather than collectively
(implicitly) contribute to the consumption of households and that, in a
sense, are closely linked to the welfare of the population, should be so
allocated. As noted, these goods and services are referred to in the terminology
of the new SNA as "individual consumption", while that part of government
expenditures that should remain in government final consumption is termed "collective
consumption". Expenditure on health, education, welfare and housing belong
to individual consumption, while expenditures on public administration,
including administration of education and health programmes, defence, research
and community services belong to collective consumption.
- Consumption financed by sectors other
than households should be valued at the cost of these expenses. Cost in
this context means compensation of employees, intermediate consumption,
consumption of fixed capital and taxes on production, if any.
- The definition of "other sectors" in
this context means mostly government and private non-profit institutions
serving households (such as charity organizations, the Red Cross etc).
Expenses by enterprises, if they serve household consumption purposes directly,
are included in remuneration in kind and not in expenditure financed by
other sectors. Transfers in kind from abroad (gifts) also are covered by
the consumption of households financed by other sectors.
- In the new SNA, there will be no
consumer subsidies and in no case will any of these subsidies be treated
as government final expenditure. When goods and services are provided free
or at such nominal prices that they do not influence demand, then the items
are to be valued at cost. When goods and services are sold at a price that
is sufficient to influence the level of demand; then they will be valued
at that price regardless of the level of subsidy that may be involved.
- A comment should also be made about
the provision of radio and televis3on services to consumers. In those countries
in which these services are commercially provided, they show up in higher
prices of the items creating the advertising revenues, and as intermediate
costs to the firms. Where radio and television are provided to households
by government, they are usually treated in government. Where they are part
non-profit and part government, these services are in both consumption
and government. A consistent treatment would be to transfer these expenditures
where commercially financed from the products that finance them, or from
government and non-profit organizations, to household recreation expenditures.
Thus far, neither the SNA nor the ICP has attempted these difficult transfers.
3. Government consumption
- As defined above, government consumption
is collective consumption. The difference between household consumption
and actual consumption is matched by an adjustment between government consumption
expenditure and actual consumption. Put another way, the transfer of individual
consumption removed from government consumption expenditures is added to
household consumption expenditure to give actual consumption.
- Government consumption is to be valued
at cost, that is, compensation of employees, intermediate consumption,
consumption of fixed capital and taxes on production, if any. This value
should be netted by fees and sales of government to other sectors, for
example, the value of the postcards sold by museums, and any other small-scale
cost-offsetting recoveries from these sectors.
- There are only a few rules to which
special attention should be drawn. Government consumption on defence includes
not only current expenditures but also expenditure on military durables
that are offensive weapons and their means of delivery. Capital items that
are purchased by the military but that could have a civilian use will in
the new SNA be treated as capital equipment. If a military durable that
had originally been treated as government consumption is converted to civilian
use, for example, a military hospital is handed over to the government
for public use, or motor vehicles such as trucks are sold to commercial
operators, this should be treated as negative government consumption in
the given period and a corresponding increase in capital formation of government
for the hospital and of the household sector for trucks.
4. Capital formation
- While there was no difference in
the concept of capital formation between the 1968 SNA and the ICP, there
will be some important changes in the new SNA that will also affect the
ICP. Capital formation, according to the new SNA, will no longer be restricted
to material capital formation only, that is, the change in stocks and fixed
capital formation. Research and development (R and D) expenditures will
still not be part of capital formation but the payment of a licence for
R and D use will be treated as a fee for a service. Human capital will
still be excluded from capital formation. However, with respect to capital
formation, several important extensions will be recommended in the new
SNA.
- One change already noted is the treatment
of military durables. In the new SNA, all mineral exploration and development
will be treated as capital formation. Further, all improvements and developments
of land such as land reclamation or planting of forests will be capital
formation in the new SNA.
- Development of computer software
and databases, whether for internal use or commercial sale, will be treated
as part of capital formation. Under certain circumstances, this will also
be true for the development of literary and artistic works.
- These changes will not immediately
affect the ICP but in the future the ICP will want to follow the new SNA.
This is likely to have implications for the basic headings of expenditures
and the core commodity list in subsequent rounds of the ICP.
5. Net exports
- Net exports, that is, exports minus
imports, is the last expenditure category on the use side of the gross
domestic product. Exports and imports cover all transactions in goods and
services between resident and non-resident economic units. There is no
difference in this respect between the SNA and the ICP. From what has been
said earlier, it follows that exports and imports also cover direct exports/imports
by households (purchases by non-resident households on the domestic market
and purchases by resident households abroad), as well as direct exports
and imports by government.
- The ICP has chosen to work with net
exports rather than deal separately with exports and imports. The reason
for this is mainly that it would require major price collection to make
price comparisons separately for exports and imports since they include
both intermediate and final products. In the future, the current ICP treatment
of the net foreign trade balance is likely to be further reviewed.
6. Dating of expenditure
totals and details
- The ICP comparisons are on a calendar-year
basis. Many countries construct their national accounts on a year beginning
on some date other than 1 January. For these countries, it is necessary
to move their estimates to a calendar basis. Unless there is reason to
believe this change in dating would greatly affect the expenditure detail,
it is normally done at the level of consumption, government, capital formation
and net exports.
- Many countries derive their basic
GDP estimates from measures of output. In subsequent calculations estimates
of expenditure categories are made where consumption is often derived as
a residual. More detailed expenditure estimates may not be available for
the most recent year for GDP because the expenditure survey or a commodity
flow survey used to generate expenditure detail is either not done annually
or lags in time behind estimates of the GDP total. What is usually done
in such cases is to apply expenditure detail for the most recent year available
to obtain estimates for the ICP benchmark year.
- One advantage of the commodity flow
approach is that it allows for improvements in the estimates of the commodity
composition of household and government consumption. It has also proved
useful for countries to examine their resulting detailed expenditure distribution
in relation to countries at a similar level of income as a check on anomalies.
Where the expenditure weights for the consumer price index are only changed
on the basis of periodic surveys, the detailed expenditures generated for
the ICP from the commodity flow approach may also prove useful for price
index purposes.
- It often happens that countries have
GDP expenditures for an ICP benchmark year, and more detailed expenditures
may be available from one or more earlier years. In the absence of benchmark
year detailed expenditure or commodity flow surveys, the most recent data
should serve as control totals. For example, if the consumption total is
known for the benchmark year, but the food percentage distribution is available
for the previous year, then the food percentage of consumption for the
previous year would be applied to the benchmark year GDP to obtain an estimate
of food expenditures in the benchmark year. And if the best detailed breakdown
within food expenditures was for a still earlier year, then that distribution
would be applied to the estimated benchmark year food total.
B. Breakdown of GDP
by aggregating of basic headings
- The task of the ICP is to compare
not only the levels of gross domestic product but also its structure. This
structure can be expressed in terms of more detailed aggregates, such as
bread and cereals, non-alcoholic beverages, or operating costs of transport,
as well as in larger aggregates, such as food or consumption of households.
These aggregate categories can be used for volume comparisons, or are equally
interesting in comparing purchasing-power parities, as was discussed above
for capital formation.
- There are several criteria that have
been used to break down GDP into the 55 aggregates given in table 2. The
breakdown starts with the main functions of the expenditure categories,
distinguishing household consumption, government consumption, capital formation
and net exports. The next criterion applied is the purpose/use of the goods
and services consumed; for example, food, clothing, transport and communication
are distinguished. Additional criteria are applied whenever feasible; these
distinguish goods from services, and, within goods, durable goods from
non-durable goods.

- Regional comparisons may adopt a
more detailed breakdown than the world comparison. However, this more detailed
breakdown must be compatible with the breakdown presented above, that is,
it should always be possible to arrive at the most detailed analytical
categories of the world breakdown by combining the analytical categories
of the regional breakdown.
C. Breakdown of GDP
by basic headings
- Each expenditure aggregate is divided
into one or more basic headings; however, the function of the two breakdowns
is quite different. The breakdown of GDP into aggregates serves data presentation
purposes: the organizers of the ICP would like to derive (interspatial)
quantity indexes and purchasing-power parities for each expenditure aggregate.
The basic heading breakdown, on the other hand, is a technical stratification
or classification, the main purpose of which is to permit better estimates
of the larger expenditure aggregates. As mentioned in chapter I, it is
not intended to publish the results at the level of the basic heading breakdown,
though they are made available to users for research purposes.
- In terms of the general theory of statistics, the
basic headings serve the purposes of stratification in order to improve
accuracy. This stems from three factors:
- It is expected that the dispersion
of the individual price ratios is smaller within the basic headings
than between the basic headings within large expenditure aggregates;
- The coverage of all expenditure
aggregates is ensured;
- The basic heading breakdown
enables weighting to be applied (i.e., to compile weighted instead
of unweighted averages of the parities) at a relatively detailed
level.
If no basic heading breakdown were applied and the
purchasing-power parities of an aggregation such as clothing were compiled
as an unweighted average of the purchasing power ratios within the category,
this would provide less accurate results because weights would to a large
extent be neglected.
- The point made in subparagraph (a)
above requires some qualification. Between basic headings of food, such
as vegetables and cereals, there may be less price variation than within
a basic heading such as recreational equipment. The point being made is
that within large aggregates such as food, price variation will be reduced
by sampling items at more detailed headings. Similarly, though overall
price variation for recreation may be quite large, by separating out basic
headings such as recreation equipment from entertainment, the price dispersion
for all of recreation will be reduced.
- In delineating basic headings from each other, two
principles have to be followed:
- The basic headings should be
as homogeneous as possible;
- Sufficiently reliable weights
(i.e., detailed expenditure data) should be available for each basic
heading.
- Homogeneity of basic headings should
be interpreted in terms of the dispersion of the individual price ratios
across countries. The smaller this dispersion, the more homogeneous a given
basic heading is considered. Of course, when basic headings are initially
delineated, no prior information is available on the dispersion of the
individual price ratios. Most of the basic headings used in the ICP correspond
to national accounting or survey divisions that have been devised for other
purposes. However, this delineation, which has been based on the kind,
type or function of the products in a basic heading, tends to produce relatively
homogeneous groupings, even in respect of the dispersion of the individual
price ratios. For instance, the dispersion of price ratios within the category "footwear" can
be expected to be smaller than within the broader category "clothing and
footwear", and within the category "men's footwear" it should be even smaller
than within the category "footwear".
- The expenditure data for basic headings
are used mainly as weights, but frequently very important weights. For
example, some countries find it difficult to separate government consumption
between wages and salaries and purchases of goods and services. However,
parities for these basic headings are different across countries. It is
therefore important to make the best possible estimate of the distribution
of collective consumption between these two headings. Even expenditure
weights for these headings of limited accuracy are likely to be more useful
than using no weights at all. This is because no weights at all would implicitly
assign equal weights in this example; only if it is not possible to improve
on that default option, should countries not attempt expenditure estimates
at the basic heading level.
- In all phases of the ICP, the number
of basic headings distinguished at the world level has been about 150,
although the number distinguished in some regional comparisons (especially
in the developed regions) has been substantially higher. The world expenditure
and basic heading list for phase VI of the ICP is provided in annex III
of the Handbook, along with a description of the types of goods and services
included under each heading.
