NATIONAL ACCOUNTS, INCLUDING
BASIC IDENTITIES
Short Course on National Accounts
IARIW-conference, August 23 – 24, 2014

Head of National Accounts
OECD
A general introduction
• Why national accounts?
• Definition and objectives
• The Value Added of national accounts?
• Circular flow of income
• Main subsystems of national accounts
• Macro-economic aggregates
• Production cycle and revision of national accounts
2
Why national accounts?
Relevance:
• Monitoring the performance of an economy with a consistent set
of indicators
• Basis for economic theory
• Model building
• Coherent policy formulation (and evaluation)
Consistency and reliability:
• National accounts is a system with identities (definitional
equations)
• Checking data with the help of identities (transaction identity;
budget identity; and balance sheet identity
3
• Complete
description of the national economy
Why national accounts?
Efficiency:
• No overlaps/gaps in the statistical programme
• Reduce administrative burden of respondents
• Uniform concepts, definitions and accounting rules (SNA 2008
and ESA 2010)
4
Definition and objectives
A comprehensive and consistent, quantitative description of
economic phenomena in a country, related to a certain
period of time
• Provides an overall picture of an economy
• Compute summary indicators for measuring performance
• Provide data for monitoring and forecasting the effects of socioeconomic policies
• Provide data within an analytical framework useful to economic
research
• Provide data for international comparison
• Provide data for administrative purposes
5
The Value Added of national accounts?
Closed and consistent framework:
• Allows for systematic analysis of the economy, but …
• … also allows for a rigorous quality check of economic
data, …
• … and provides an excellent tool for compiling consistent
data …
• … by making use of the various identities!
6
The Value Added of national accounts?
Transaction identity
•
For each product: Total supply = Total demand, or P +
M = C + I + E + IC
•
For each transaction: Total payments = Total receipts
Budget identity
•
Balance of non-financial transactions = Balance of
financial transactions (double bookkeeping)
7
The Value Added of national accounts?
Balance sheet identity
•
For each balance sheet item (non-financial as well as
financial): change in stock between two years =
transactions + holding gains/losses + other changes in
volume
•
Also true for Net Worth: change in in the balance sheet
item Net Worth = changes in net worth (CNW) due to
savings and capital transfers + CNW due to holding
gains and losses + CNW due to other changes in
volume

Circular flow of income, and …
• Exchanges with other systems:
– other countries (imports, exports, transfers)
– other periods (saving, investment,
depreciation)
• Financial transactions
• Other changes in assets and liabilities, such as
holding gains/losses and other changes in
volume
• Balance sheets

Main subsystems of national accounts
Sector accounts
• Units classified in institutional sectors
• Complete description of economic transactions and
stocks of institutional sectors
• Transactions classified in accounts representing a
specific economic process (e.g. production, income
distribution, use of income, accumulation)
• Derivation of relevant balancing items (e.g. gross
domestic product, net national income)
17
Main subsystems of national accounts
Main institutional sectors
• Non-financial Corporations
• Financial Corporations
• General Government
• Households
• Non-profit Institutions serving Households
• Rest of the World
18
Main subsystems of national accounts
Main accounts distinguished (including balancing item):
1. Production
2. Primary distribution of income
3. Secondary distribution of income
4. Use of income
5. Capital account
6. Financial account
7. Other changes in assets
8. Balance sheets

Main subsystems of national accounts
Supply and Use Tables
• Detailed description of production process
• Description of supply and use of goods and services
• Units classified in industries
• Supply table: row gives supply of specific product groups
• Supply table: column gives total production by industry
• Use table: row gives destination of specific product group
• Use table: column gives use of products in production
process
and resulting value added by industry

Main subsystems of national accounts
Labour accounts:
• Integrated dataset on labour and wages
• Consistency with corresponding data in sector accounts
and supply and use tables
• Examples: data on population and labour force,
employment (hours worked, number of jobs, number of
employees/self employed), compensation of employees
24
Macro-economic aggregates
1. GROSS DOMESTIC PRODUCT (GDP)
=
output - intermediate consumption
=
compensation of employees +
gross operating surplus +
net taxes on production
=
final consumption expenditure +
gross fixed capital formation +
25
exports – imports
Macro-economic aggregates
Thus also three methods for estimating GDP:
1. Production approach
2. Income approach
3. Expenditure approach
1 and 3 combined in Supply and Use Tables
26
Macro-economic aggregates
2. NET NATIONAL INCOME (NNI) =
gross domestic product (GDP)
+ primary income received from the rest of the world
- primary income paid to the rest of the world
- consumption of fixed capital
27
Macro-economic aggregates
3. NET NATIONAL DISPOSABLE INCOME =
net national income (NNI)
+ current transfers received from the rest of the world
- current transfers paid to the rest of the world
28
Macro-economic aggregates
4. NET NATIONAL SAVING =
net national disposable income
- final consumption expenditure
29
Macro-economic aggregates
5. NET LENDING/BORROWING =
net national saving
+ capital transfers received from the ROW
- capital transfers paid to the ROW
- fixed capital formation, net
30
Macro-economic aggregates
5-7.
TOTAL CHANGES IN NET NATIONAL WORTH =
net national saving
+ capital transfers received from the ROW
- capital transfers paid to the ROW
+ net other volume changes in national assets and
liabilities
+ net nominal holding gains of national assets and
liabilities
31
Macro-economic aggregates
8. NET NATIONAL WORTH =
national non-financial assets
+ national financial assets
- national financial liabilities
32
Production cycle and revision process
Typical production cycle
• Quarterly data
- Flash estimates for GDP (t + 30/45 days)
- Regular estimates, including sector accounts (t+90 days)
- Remark: quarterly data need to be adjusted to new annual data
• Annual data
- Provisional data (t + 6-9 months)
- Improved provisional data (t + 18-21 months)
- Final data (t + 30-33 months)
- May slightly differ by country
33
Production cycle and revision process
Benchmark revisions
- Comparability in time: growth rates versus level estimates
Reasons
- Changes in international standards
- New/adjusted sources and methodologies
- Problems with ‘reconciliation’ of the data
- Consistency between national accounts subsystems
Frequency
-
