CHAPTER 6 THE NATIONAL INCOME ACCOUNTS
LESSON 1 MEASUREMENT OF NATIONAL INCOME
OVERVIEW • THE INCOME OF THE NATION IS MEASURED BY THE TOTAL EARNINGS OF THE FACTORS OF PRODUCTION OWNED BY ITS CITIZENS OR BY THE TOTAL MARKET VALUE OF ALL FINAL GOODS AND SERVICES PRODUCED BY THE CITIZENS. • SUCH EARNINGS OR MARKET VALUE OF FINAL GOODS AND SERVICES ARE ESTIMATED ON A YEARLY BASIS. SUCH MEASUREMENTS REFLECT THE PERFORMANCE OF THE ECONOMY.
THE GROSS NATIONAL PRODUCT • The Gross National Product or GNP refers to the market value of all the final products produced by the resources of the economy during na specified period of time. • GNP reflects the value of the products flowing in the circular flow, the production of which entails the use of the economy’s economic resources.
THREE MAJOR TYPES OF GOODS IN THE GNP 1. Goods and services which enter into the channel of trade and commerce; 2. Products which are produced and consumed by the producers; and
3. Imputed value in rentals. Note: 1. GNP excludes second-hand items as they merely represent a change in ownership of a good produced earlier, unless there is capital gain. 2. Final product is merely an attempt to avoid double counting – a problems that makes the determination of the gross national product very difficult.

Final product is merely an attempt to avoid double counting – a problems that makes the determination of the gross national product very difficult.
LIMITATION OF GNP 1. The national income in less developed countries is understated insofar as many products which have been produced and consumed are excluded (small-scale industries whose products are only used for family consumption, various trade transactions, some of which are not place in the market).
2. Inadequacy and inaccuracy of statistics. 3. GNP only measures the number of goods and services but not the quality of goods and services. 4. GNP does not reflect the distribution of income among members of society. Income of the rich and poor are combined to come up with an average per capita income (PCI). 5. Per Capital Income (PCI) is income per head.
LIMITATION OF GNP 5. Per Capital Income (PCI) is income per head. The formula is: PCI = National Income Population
SO, IF THE NATIONAL INCOME IS PHP 950,000,000,000.00 AND THE POPULATION IS 100,000,000, PCI IS PHP 9,500.00.
THE GROSS DOMESTIC PRODUCT (GDP) • The Gross Domestic Product (GDP) is comprised of final goods and services produced with national boundaries. • The GDP is a tool that measures the value of all locallyproduced goods and services at market price.
• GDP does not include the earnings of Filipino factors of production abroad as they are part of GNP.
THE DIFFERENCE BETWEEN GDP AND GNP • The difference between GDP and GNP is called net factor income from abroad (NFIA). • It regards earnings of banking system as inflows and repatriation to foreign factors of production as outflows.
• NFIA is added to GDP to arrive at GNP. • A simple formula is: GNP = GDP + NET FACTOR INCOME FROM ABROAD.
THE DIFFERENCE BETWEEN GDP AND GNP
MEASURING THE GNP • The GNP can be measured in two (2) ways: 1. CURRENT GNP 2. REAL GNP CURRENT GNP = PcQc Where: Pc = Current Price Qc = Current Volume of Goods and Services
• At current price, GNP could not be exactly determined. An increase in prices of goods and services will automatically increase the GNP even if there is no actual increase in the volume of production.
MEASURING THE GNP • If GNP is really made to measure the market value of total production, the effect of price changes must be eliminated so as to show GNP values which reflect only changes in quantity. REAL GNP • The measurement using a base or constant price. • This means expressing GNP for several years at prices of a single year. • In real GNP, the effect of price changes is eliminated so as to show GNP values which reflect only changes in quantity. • Real GNP is computed from current GNP using a price coefficient known as the PRICE INDEX or GNP deflator. • A price index is needed to divided the GNP current prizes in order to reexpress it at constant peso terms. • The price index must reflect well the average increase of prices of all goods and services using the price of a given year as the point of comparison.
MEASURING THE GNP REAL GNP • Formula: REAL GNP = CURRENT GNP PURE NO. INDEX WHERE: PURE NO. INDEX = PRICE OF CURRENT YEAR BASE YEAR PRICE
MEASURING THE GNP REAL GNP PURE NO. INDEX = PRICE OF CURRENT YEAR BASE YEAR PRICE

WITH THE REAL GNP, WE ARE NOW SURE THAT THE INCREASE IN GNP IS DUE TO THE ACTUAL INCREASE IN THE VOLUME OF PRODUCTION, AND NOT DUE TO THE INCREASE IN PRICES OF GOODS AND SERVICES.
LESSON 2 OTHER APPROACHES OF MEASURING GNP
EXPENDITURE APPROACH 1. GNP IS MEASURED IN TERMS OF TOTAL SALES OF THE ECONOMY, WHICH ARE BASICALLY , THE TOTAL EXPENDITURES OF OUR ECONOMY. 2. GNP IS THE SUMMATION OF THE CONSUMPTION, INVESTMENT, GOVERNMENT EXPENDITURES AND EXPORT MINUS IMPORTS OR NET EXPORTS.
GNP = C + I + G + (X – M) Where: C
=
I G X–M
= = =
Consumption spending by household /Private Consumption Expenditures Investment Government Spending Exports minus Imports (Net Exports)

2.
NATIONAL INCOME IS THE SUM TOTAL OF ALL FACTOR INCOME OF PERSONS AND HOUSEHOLD (WAGES AND SALARIES, PROFITS AND DIVIDENDS, RENT AND INTEEST) AND GOVERNMENT INCOME DERIVED FROM CAPITAL AND UNDISTRIBUTED CORPORATE INCOME.
3.
NATIONAL INCOME IS INCLUSIVE ALSO OF INDIRECT TAX, A TAX PAID ON THE SALE OF PRODUCT USUALLY SHOULDERED BY THE CONSUMERS AND DEPRECIATION ALLOWANCE WHICH IS A FEE FOR THE PRESENT USE OF MACHINES AND BUILDINGS THAT HAS BEEN INSTALLED IN THE PAST.

LESSON 4 THE DISTRIBUTION OF NATIONAL INCOME
MEANING OF INCOME DISTRIBUTION INCOME DISTRIBUTION
•
THE ALLOCATION OF INCOME AMONG THE OWNERS OF THE FACTORS OF PRODUCTION
•
IT IS THROUGH THIS THAT INCOMES ARE APPORTIONED/ALLOCATED TO THE DIFFERENT MEMBERS OF SOCIETY.
•
ONE MAY RECEIVE MORE WHILE OTHERS RECEIVE LESS.
•
MOST OF THE PRODUCTIVE RESOURCES BELONG TO THE VERY FEW INDIVIDUALS, WHILE WORKERS AND EMPLOYEES ARE GIVEN LOW WAGES.
•
THE OTHER SOURCES OF INCOME LIKE RENTS, INTERESTS, AND PROFITS ARE MUCH HIGHER.
•
SUCH A DISMAL ECONOMIC CONDITION OF THE POOR HAS BEEN A PRODUCT OF OUR EXISTING SOCIO-ECONOMIC STRUCTURE.
MEANING OF INCOME DISTRIBUTION TYPES OF INCOME DISTRIBUTION
1.
PERSONAL DISTRIBUTION – DEALS WITH THE ALLOCATION OF INCOME AMONG PERSONS OR HOUSEHOLDS AND THE TOTAL INCOME THEY RECEIVE • THE DEGREE OF INCOME INEQUALITY AMONG HOUSEHOLDS OR FAMILIES IS SHOWN BY THE LORENZ CURVE.
% OF INCOME
• THE VERTICAL AXIX REPRESENTS “PERCENT OF INCOME” WHILE THE HORIZONTAL AXIS IS THE “PERCENT OF FAMILIES. • THE DIAGONAL LINE SHOWS PERFECT INCOME EQUALITY AMONG FAMILIES. • THE FURTHER THE LORENZ CURVE FROM THE LINE OF EQUALITY, THE GREATER IS INCOME INEQUALITY AMONG FAMILIES
