About the Author
The author of this research study is the student of Post Graduate Diploma in
Public Administration (PGDAP-2013-14) and this research has been carry
out to fulfill the requirement of the PGDPA degree program.
The aim of the research is to provide complete understanding about the
Gross Domestic Product (GDP) as an economic indicator. First it has been
describe that how the GDP of a country has been calculated and what factors
are the part of the GDP and how the GDP explains the economic growth of a
country.
Furthermore, it has been try to find out the economic indicators other than
the GDP which provides more effective understanding of the economic well
being.

Abstract
Gross Domestic Product (GDP) is the value of aggregate production in a
country during a given period (usually a year). The concept of GDP is based
on the distinction between stocks and flows and the circular flow of
expenditure and income.
Capital is the key macroeconomic stock, and investment is the flow that
increases the stock of capital. Wealth is also a stock, and saving-income
minus consumption expenditure-increases the stock wealth.
The circular flow of income and expenditure arises from the expenditures
of households, firms, governments, and the rest of the world and the payment
of factors incomes by firms. Aggregate expenditure on goods and services
equals to aggregate income. The value of aggregate production-GDP-is equal
to aggregate expenditure or aggregate income in an economy. Because
aggregate expenditure, aggregate income, and the value of aggregate
production are equal, national income accountants can measure the GDP by
using one of two approaches:
 The Expenditure Approach
 The Factor Incomes Approach
Inflation is measured by the rate of change of the GDP deflator. GDP
deflator gives an upward biased measure of inflation because some goods
disappear and new goods become available, and the quality of goods and
services change overtime.
Real GDP is not a perfect measure of either aggregate production or
economic welfare. It excludes quality improvements, household production,
and the underground economy, environmental damage, the contribution to
economic welfare of health and life expectancy leisure time, and political
freedom and social justice. But the growth rate of real GDP gives a good
indication of the phases of the business cycle. The change in real GDP also
reflects the changes in the unemployment rate in an economy.
This pilot study provides a concrete understanding of the topic and
base for the further research to intricate the topic.

Introduction
Back Ground of the Study:
Economic development involves growth in the economic wealth of an
economy. Government policy in many countries generally aims for continuous
and sustained economic growth, so that their economies expand and become
more developed. Many less developed countries lack the capital required to
invest in modern infrastructure such as road and power networks, and they
also lack the consumer demand required to stimulate investments in an
industrial base and service sector. Instead, less developed countries tend to
depend heavily on agriculture for employment and incomes. It is the one of
the reason of slow economic growth in these countries.
Problem Statement:
Is the Gross Domestic Product (GDP) the only and the authentic
economic indicator to measure the economic development of a country? And
the difference between the less developed and developed economies are their
GDP growth or the government should consider other economic indicators for
the sustainable economic growth and development?
Significance of Study:
The study reveals that how the economic growth of the countries can
be measured. And, how the other economic indicator describes the social
well-being of the people of the country.
Research Methodology:
The Literature review method has been used to define the hypothesis.
Which includes the review of books, previous research work on the same
topic or related to the topic and references from the authentic web sites?
We try to explore the actual facts regarding economic development or the
real factors which contributes in the development of an economy. For the
same, we try to get the answers of the questions (See Appendix).

Qualitative Method:
The data collected for this research is secondary in nature. It is
collected with the idea to add personal in-depth introspective opinions and
meaningful to the study.
Hypothesis:
Ho: Gross Domestic Product (GDP) is the authentic economic indicator
to measure the economic well being of the country in addition to people
of the country.
HĄ: Gross Domestic Product (GDP) is not the authentic economic
indicator to measure the economic well being of the country in addition
to people of the country.
What is Gross Domestic Product (GDP)?
Gross Domestic Product (GDP) is the value of aggregate or total
production of goods and services in a country during a given time period-
usually one year.
How it is calculated? Two fundamental concepts from the foundation on
which GDP measurements are based:
 The distinction between stocks and flows,
 The equality of income, expenditure, and the value of production.

Page 7 of 41
Stock and Flows:
To keep track of our personal economic transactions and the economic
transactions of a country, we distinguish between stocks and flows.
Stock:
A stock is a quantity that exists at a point in time. The water in a
bathtub is a stock. So are the numbers of the current deposits (CDs)
that are you own and the amount of money in your savings accounts.
Flow:
A flow is a quantity per unit of time. The water that is running from an
open faucet into a bathtub is a flow. So are the number of current
deposits (CDs) that you buy during a month and the amount of income
that you earn during a month.
GDP has another flow, it is the value of the goods and services
produced in a country during a given time period usually a year.
Capital and Investment:
Capital:
The key macroeconomic stock is Capital. Capital is the plant,
equipments, buildings, and inventories of raw materials and semi
finished goods and services. The amount of capital in the economy is
crucial factors that influence GDP. Two macroeconomic flows changes
the stock of capital: Investments and depreciations.
Investment:
Investment is the purchase of new plant, equipment, and buildings and
the additions to inventories. Investment increases the stock of capital.
Depreciation:
Deprecation is the decrease in the stock of capital that results from
wear and tear and the passage of time. Another name for depreciation
is capital consumption.

Page 8 of 41
The total amount spent on adding to the stock of capital and on
replacing depreciated capital is called Gross Investment.
The amount spent an adding to the stock of capital is called Net
Investment equals Gross Investment minus Depreciation.
Net investment = Gross Investment - Depreciation
Wealth and Saving:
Wealth:
Another macroeconomic stock is wealth, which is the value of all the
things that people own. What people own, a stock, is related to what
they earn a flow. People earn an income, which is the amount they
receive during a given time period from supplying the services of
factors of production. Income can be either consumed or saved.
Consumption Expenditure is the amount spent on consumption goods
and services.
Saving:
Saving is the amount of income remaining after meeting consumption
expenditures. Saving adds to wealth and dissaving (negative saving)
decreases wealth.
National wealth and national saving work just like personal savings.
The wealth of a nation at the start of a year equals its wealth at the start of
the previous year plus its saving during the year. Its saving equals its income
minus its consumption expenditure.
Nation’s saving = Income - Consumption Expenditure
The Equality of Income, Expenditure and Value of Production:
The circular flow of income and expenditure helps us to see the
economy as whole income equals to expenditure and also equals the value of
production.
To keep track of the different types of flows that make up the circular
flow of income and expenditure, they are color-coded.

In the circular flow of income and expenditure, households receive
incomes (Y) from firms (blue flows) and make consumption expenditures (C),
firms make investment (I), governments purchase goods and services (G), the
rest of the world purchase net exports (NX) – (red flows). Aggregate income
(blue flow) equals aggregate expenditure (red flows).
Households’ savings (S) and net taxes (NT) leak from the circular flow.
Firms borrow to finance their investment expenditures, and governments and
the rest of the world borrow to finance their deficits or lend their surpluses
(green flows).

Firm’s Borrowing
In the circular flow of income and expenditure consists of four sectors:
 Households,
 Firms,
 Governments and
 Rest of the world.
It has been three aggregate markets:
 Factors Markets,
 Goods and Services Markets, and
 Financial Markets.
Household and Firms:
Households sell and firms buy the services of labor, capital, land and
entrepreneurship in factor markets. For these factors services, firms pay
income to households: wages for labor services, interest for the use of
capital, rent for the use of land, and profits for entrepreneurship. Firm’s
retained earnings –profits that are not distributed to households-are also part
of the household sector’s income.
The total income received by all households in payment for the
services of factors of production is aggregate income. In diagram aggregate
income denote by ‘Y”.
Firms sell and households buy consumer goods and services in the
markets. The aggregate payment that households make for these goods and
services is consumption expenditure. In circular flow ‘C’ represents the
consumption expenditure.
Firms buy and sell new capital equipment in the goods market. The
purchase of new plant, equipment, and buildings and the additions to
inventories are investment.
The circular flow diagram shows investment by the red dots labeled ‘I’.
Notice that in the figure, investment flows from firms through the goods
markets and back to firms.

Page 11 of 41
Some firms produce capital goods, and other firms buy them (and firms
‘buy’ inventories form themselves).
Firms finance their investment by borrowing from households in
financial markets. Household’s saving flows into financial markets and firm’s
borrowing flows out of financial markets. The circular flow diagram shows
these flows by the green dots labeled “Households’ saving” or ‘S’ and “firms
borrowing. These flows are neither income nor expenditure. Income is a
payment for the services of factor of production, and expenditure is a
payment for goods or services.
Governments:
Governments buy goods and services, called government purchases,
from firms. In the circular flow diagram, these government purchases are
shown as the red flow ‘G’. Governments use taxes to pay for their purchases.
In diagram, green dots labeled ‘NT’ shows taxes as net taxes. Net taxes are
equal to taxes paid to governments minus transfer payments received from
governments.
Net Taxes = Total Taxes Received by the Governments –
Transfer Payment paid by Governments
Transfer payments are cash transfers payments received from
governments. Transfer payments are cash transfer payments are cash
transfers from governments to households and firms such as social benefits,
society developments, unemployment and other subsidies.
When government purchases ‘G’ exceed net taxes ‘NT’, the
government sector has a budget deficit, which is finance by borrowing in
financial markets. This borrowing is shown by the green dots labeled
“Government Borrowing”.
Rest of World Sector:
Firms export goods and services to the rest of the world and import
goods and services from the rest of the world. The value of exports minus
the values of imports is called net exports. It is the red flow ‘NX’.
Net Export = Exports - Import
If value of exports exceeds the value of imports, net exports are
positive and flow from the rest of the world to firms. But if the value of

Page 12 of 41
exports is less than the value of imports, net exports are negative and flow
from firms to the rest of the world.
When net exports are positive, the rest of the world either borrows
from the domestic economy or sells domestic assets that it has bought
previously. These transactions take place in financial markets and they are
shown by the green place in financial markets and they are shown by the
green flow labeled “Foreign Borrowing”. When net exports are negative, the
domestic economy either borrows from the rest of the world or sells foreign
assets that it had previously acquired. Again, these transactions take place in
the figure; we would reserve the directions of the flows of net exports and
foreign borrowing.
Measuring Gross Domestic Product (GDP)
Gross Domestic product (GDP) is the value of aggregate production in a
country during a year. Production can be valued in two ways:
1. By what buyers pay for it,
2. By what it costs producers to make it.
From the view-point of buyers, goods are worth the prices paid for
them.
It will be a real nuisance if these two values are different because we
will then have two different measures of GDP. But if these two values are
always equal, we will have a unique concept of GDP regardless of which one
we use.
Fortunately, the two concepts of value do give the same answer. Let’s
see, why it’s happen?
Expenditure Equals Income:
The total amount that buyers pay for the goods and services produced
is aggregate expenditure. Let’s analyze the aggregate expenditure in circular
flow diagram. The expenditure on goods and services are shown by the red
flows. Firm’s revenues from the sale of goods and services equal
consumption expenditure (C) plus investment (I) plus government purchases
of goods and services (G) plus net exports (NX). The sum of these four flows
in the economy equal to aggregate expenditure on goods and services.

Page 13 of 41
The total amount it costs producers to make goods and services is
equal to the incomes paid for factor services. This amount is shown is
circular flow by the blue.
The sum of the red flows equals the blue flow. The reason is that
everything a firm receives from the sale of its output is paid out as incomes
to the owners of the factors of production that it employs. That is,
Y = C + I + G + NX
Or
Aggregate income (Y) equals to (=) Aggregate expenditure (C + I + G + NX)
The buyers of aggregate production pay an amount equal to aggregate
expenditure, and the sellers of aggregate production pay on amount equal to
aggregate income, these two methods of valuing aggregate production, GDP,
equals aggregate expenditure or aggregate income.
The circular flow income and expenditure is the foundation for
measuring GDP. At the same time, it is foundation for understanding how the
finance investment flows and translate into growing capital stock.
How investment is financed in The Economy:
Investment is financed by national saving and by borrowing from the
rest of the world. National Savings equal household saving plus government
savings. Borrowing from the rest of the world equals the value of imports
minus the value of experts (or the negative of net exports). Let’s analyze how
these sources of funds combine to finance investment.
National Savings:
The flows into and out of households in circular flow diagram shows,
aggregate income (Y) flows in, and consumption expenditure (C), saving (S),
and net taxes (NT) flow out. Everything received by households is either
spent on consumption goods and services, saved, or paid in net taxes, so:
Y = C + S + NT
And household saving is:
S = (Y – NT) – C

Page 14 of 41
Aggregate income minus net taxes (Y – NT) is called disposable
income, so household saving equals disposable income minus consumption
expenditure.
Government saving equals net taxes minus government purchases,
(NT – G), which is the government budget surplus. If net taxes exceed
government purchases that is (NT – G) is positive, the government has a
budget surplus and this surplus is added to household saving as an additional
source of finance for investment.
But if net taxes are less than government purchases, this is, if (NT – G)
is negative, the government has a budget deficit and has to finance the
government deficit.
National Savings equals household savings plus government savings:
National Savings = S + (NT – G)
But because household savings equal disposable income minus
consumption expenditure:
National Savings = (Y – NT) – C + (NT – G)
Now we can say that net taxes cancel in the above equation. Household
pay then and government’s receive them, so when we add household saving
and government saving together, they wash out and we are left with:
National Savings = Y – C – G
National Savings equals aggregate income (GDP) minus consumption
expenditure minus government purchases.
Borrowing From The Rest Of The World:
If rest of the world spends more on our goods and services than we
spend on theirs, they must borrow to pay the difference.
That is, if the value of exports (EX) exceeds the value of imports (IM),
then we can lend to the rest of the world an amount equal to (EX – IM). In this
situation, part of national saving flows to the rest of the world and is not
available to finance investment.

Page 15 of 41
Conversely, if we spend more on foreign goods and services than the
rest of the world spends on our, we must borrow from the rest of the world to
pay the difference. That is, if the value of imports (IM) exceeds the value of
exports (EX), then we must borrow from the rest of the world an amount
equal to (IM – EX). In this case, part of the rest of the world’s saving flows
into the economy and becomes available to finance investment.
Investment Financing:
The total funds available to finance investment equals national saving,
S + (NT – G), plus borrowing from the rest of the world, (IM – EX). This
amount equals investment. That is,
I = S + (NT – G) + (IM – EX)
That is, investment (I) equals household saving (S) plus government
saving (NT – G) plus borrowing from the rest of the world (IM – EX).
Injection And Leakages:
The circular flow of income and expenditure as a system of tubes with
liquid flowing through them. The flow of factor incomes equals the flow of
expenditures. But some liquid leaks from the circular flow. The leakages from
the circular flow are saving, net taxes, and imports. For the flows to not run
dry there must also be some injections into circular flow. The injections are
investment, government purchases of goods and services, and exports.
I = S + (NT – G) + (IM – EX)
Add government purchases (G) and export (EX) to both sides of this
equation and we get:
=
INJECTIONS LEAKAGES
The left side is injections into the circular flow of income and
expenditure, and the right side is leakages from the circular flow.
I + G + EX
S + NT + IM

Page 16 of 41
Now, we analyze that how Economic Staticians of country use the
circular flow of income and expenditure to measure GDP.
Measuring The GDP of Country
To measure the GDP of a country, economic statician uses two
approaches:
 Expenditure Approach
 Factor Approach
The Expenditure Approach:
The expenditure approach measures GDP by collecting data on
consumption expenditure (C), investment (I), government purchases of goods
and services (G), and net exports (NX). It can be explain in tabular form:

The amounts can be shown in billions. The name of the item used in the
National Income appears in first column, and symbol we have used in our GDP
equations appears in the next column.
To measure GDP using the expenditure approach, we add together
personal consumption expenditures (C), gross private domestic investment

Page 17 of 41
(I), government purchases of goods and services (G), and net exports of
goods and services (NX).
Personal Consumption Expenditures:
Personal consumption expenditures are the expenditures by households
on goods and services produced in the rest of the world. They include
all goods and services but do not include the purchase of new
residential houses, which is counted as part of investment.
Gross Private Domestic Investment:
Gross private domestic investment is expenditure on capital equipment
and buildings by firms and expenditure on new residential houses by
households. It also includes the change in firms’ inventories.
Government Purchase of Goods and Services:
Government purchases of goods and services are the purchases of
goods and services by all levels of governments. This item of
expenditure includes the cost of providing national defense, law and
order, street lighting, garbage collection, and so on. It does not include
transfer payments. Such payments do not represent purchases of goods
and services but rather transfers of funds from government to
households.
Net exports of goods and services are the value of exports minus the
value of imports.
Net Exports = Net Exports- Net Imports
Expenditures Not In GDP:
Aggregate expenditure, which equals GDP, does not include all the
things that people and businesses buy. To distinguish total expenditure
on GDP from other items of spending, we call the expenditure included
in GDP final expenditure. Spending that is not part of final expenditure
and not part of GDP include the purchases of:
 Intermediate Goods and Services
 Use Goods,
 Financial Assets

Page 18 of 41
Intermediate Goods and Services:
These are the goods and services that firms buy from each other and
use as inputs in the goods and services that they eventually sell to final
users.
To count the expenditure in intermediate goods and services as well as
the expenditure on the final good involves counting the same thing
twice-called double counting.
Some goods are sometimes intermediate goods and sometimes final
goods. Whether a good is intermediate or final depends on what it is
used for, not on what it is.
Expenditure on Used Goods is not a part of GDP because these goods
were counted as a part of GDP in the period in which they were
produced and in which they were produced and in which they were new
goods.
Firms often sell financial assets such as bonds and stocks to finance
purchases of newly produced capital goods. The expenditure on newly
produced capital goods is part of GDP, but the expenditure on financial
securities is not. GDP includes the amount spent on new capital, not the
amount spent on pieces of paper.
Now we try to understand the other way of measuring GDP of a country.
The Factor Incomes Approach:
The factor incomes approach measures GDP by adding together all the
incomes paid by firms to households for the services of the factors of
production they hire--wages for Labor, interest of capital, rent for land and
profits paid for entrepreneurship. Let’s elaborate how the factor incomes
approach works.
The National Income divides factor incomes into five categories:
1. Compensation of Employees
2. Net Interest

5. Proprietors’ Income

Compensation of Employees:
Consumption of employees is the total payments by firms for labor
services. This item includes the net wages and salaries (called “take-
home pay”) that workers receive each week or month plus taxes with
held on earnings plus fringe benefits such as social benefits and
pension fund contributions.
Net Interest:
Net interest is the total interest payments received by households on
loans made by them minus the interest payments made by households
on their own borrowing. This item includes, on the plus side, payments
of interest by firms to households on bonds and, on the minus side,
households’ interest payments on the outstanding balances on their
credit cards.
Rental Income:

Page 20 of 41
Rental income is the payment for the use of land and rental inputs. It
includes payments for rental housing and imputed rent for owner-
occupied housing. (Imputed rent is an estimate of what homeowners
would pay to rent the housing they own and use themselves. By
including income accounts, we measure the total value of housing
service, whether they are owned or rental.)
Corporate Profits:
Corporate profits are the profits made by corporations. Some of these
profits are paid to household in the form of dividends, and some are
retained by corporations as undistributed profits.
Proprietors’ Income:
Proprietors’ income is a mixture of the elements that we have just
reviewed. The proprietor of an owner-operated business supplies
labor, capital and perhaps land and buildings to the business. It is
difficult to split the income earned by an owner-operator into
compensation for labor, payment for the use of capital, rent payments
for the use of land or buildings and profit, so the national income
accounts lump all these separate incomes into a single category.
The sum of these five components of factor incomes is called net
domestic income at factor cost. It is not GDP. Two further adjustments
are needed to get to GDP, one from factor cost to market price and
another from net to gross.
Factor Cost To Market Price:
When we add up all the final expenditures on goods and services, we
arrive at a total called domestic product at market price. These
expenditures are valued at the market prices that people pay for the
various goods and services.
Another way of valuing goods and services is at factor cost. Factor
cost is the value of a good or service measured by cost. Factor cost is
the value of a good or service measured by adding together the costs
of all the factors of production used to produce it. If the only economic
transaction is between households and firms – if there are no
government taxes or subsidies – the market price and factor cost

Page 21 of 41
values would be same. But the presence of indirect taxes and subsidies
makes these two methods of valuation differ.
An indirect tax is a tax paid by consumers when they buy goods and
services. (In contrast, a direct tax is tax on income.) State sales tax
and taxes on products (gasoline, tobacco, etc.) are indirect taxes.
Because of indirect taxes, consumers pay more for some goods and
services then the factor cost.
A subsidiary is a payment by the government to producer. Payments
made to gain growers and dairy farmers are subsidies. Because of
subsidies, consumers pay less for same goods and services than
producers receive. The market price is less than the factor cost.
To use the factor incomes approach to measure GDP, we must add
indirect taxes to total factor incomes and subtract subsidies. Making
this adjustment brings us are step closer to GDP, but it does not quite
get us there. To achieve the GDP, we have to make another
adjustment.
Net Domestic Product To Gross Domestic Product:
If we total all the factor incomes and then add indirect taxes and
subtract subsidies, we arrive at net domestic product at market price.
What do the words Gross and Net mean?
The word Gross means before subtracting depreciation - the decrease
in the value of the capital stock that results from wear and tear and the
passage of time. Similarly, the word Net means after subtracting
depreciation.
A component of aggregate expenditure is gross investment – the
purchase of new capital and the replacement of depreciated capital. So
when we total all the expenditures, we arrive at a number that includes
that amount of depreciation, a gross measure.
A component of aggregate factor income is the net profit of business
-profit after subtracting the deprecation of capital. So, when we total
all the factor incomes, we arrive at a number that excludes
depreciation, a net measure.

Page 22 of 41
The above given table summarizes these calculations and explains how
the factor income leads to the same estimate of GDP as the expenditure
approach.
The Price Level And GDP
The price level is the average level of prices of products measured by
a price index. To construct a price index, we take a basket of goods and
services and calculate its value in the current period. The price index is the
value of the basket in the current period expressed as a percentage of the
value of the same basket in the base period. This change of prices is called
inflation.
The two main price indexes that are used to measure the price level are:
 The Consumer Price index
 The GDP Deflator
The Consumer Price Index (CPI):
We will discuss the Consumer Price index in brief. The consumer price
index can be defined as follows:
A consumer price index (CPI) measures changes in the price level of
market basket of consumer goods and services purchased by households.
Or
A measure of changes in the purchasing-power of a currency and
the rate of inflation. The consumer price index expresses
the current prices of a basket of goods and services in terms of the prices
during the same period in a previous year, to show effect
of inflation on purchasing power. It is one of the best known lagging
indicators.
Or
The consumer price index (CPI) is a measure that examines the
weighted average of prices of a basket of consumer goods and services, such
as transportation, food and medical care.

Page 23 of 41
The CPI is calculated by taking price changes for each item in the
predetermined basket of goods and averaging them; the goods are weighted
according to their importance. Changes in CPI are used to assess price
changes associated with the cost of living.
The CPI is a statistical estimate constructed using the prices of a
sample of representative items whose prices are collected periodically. Sub-
indexes and sub-sub-indexes are computed for different categories and sub-
categories of goods and services, being combined to produce the overall
index with weights reflecting their shares in the total of the consumer
expenditures covered by the index. It is one of several price
indices calculated by most national statistical agencies. The annual
percentage change in a CPI is used as a measure of inflation.
A CPI can be used to index (i.e., adjust for the effect of inflation) the
real value of wages, salaries, pensions, for regulating prices and for deflating
monetary magnitudes to show changes in real values. In most countries, the
CPI is, along with the population census and the National Income and Product
Accounts, one of the most closely watched national economic statistics.
What is 'Weighted Average'?
Weighted average is an average in which each quantity to be averaged
is assigned a weight. These weightings determine the relative
importance of each quantity on the average. Weightings are the
equivalent of having that many like items with the same value involved
in the average.
What are 'Consumer Goods'?
Consumer goods are products that are purchased for consumption by
the average consumer. Alternatively called final goods, consumer
goods are the end result of production and manufacturing and are what
a consumer will see on the store shelf. Clothing, food, automobiles and
jewelry are all examples of consumer goods. Basic materials such as
copper are not considered consumer goods because they must be
transformed into usable products.
What is a 'Price Change'?
A price change is the difference in the cost of an asset or security from
one period to another. While it can be computed for any length of time,
the most commonly cited price change in the financial media is the
"daily price change", which is the change in the price of a stock or

Page 24 of 41
security from the previous trading day's close to the current day's
close. Price change over a period of time such as year-to-date or past
12 months are also commonly used time periods, and is generally
computed as a percentage change.
What is a Basket Of Goods?
A relatively fixed set of consumer products and services valued and
used on an annual basis to track inflation in a specific market or
country. The goods in the basket are often adjusted periodically to
account for changes in consumer habits the basket of goods is used
primarily to calculate the Consumer Price Index (CPI).
What is Inflation?
Inflation is the rate at which the general level of prices for goods and
services is rising and, consequently, the purchasing power of currency
is falling. Central banks attempt to limit inflation, and avoid deflation, in
order to keep the economy running smoothly.
What is Annual basis Annual Basis?
The return earned by an investment over the course of a year.
Projections containing the phrase "on an annual basis" have usually
used less than a year's worth of data to project a full year's worth of
returns. For example, an investment might have returned 1.5% in one
month. By multiplying this return by 12, an 18% annual basis is the
result. The shorter the period of data used to determine an annual
return, the less accurate that projection is likely to be. Statements
about what an investment will return on an annual basis are always
estimates.
What is Cost of Living?
The amount of money needed to sustain a certain level of living,
including basic expenses such as housing, food, taxes, and healthcare.
Cost of living is often used when comparing how expensive it is to live
in one city versus another.
Calculating the CPI for a single item:

Nominal GDP
CPI = Updated Cost X 100
Base Period Cost
The GDP Deflator:
The GDP Deflator measures the average level of price of all the goods and
services that are included in GDP.
To calculate the GDP deflator, we use the formula:
GDP Deflator = Nominal GDP X 100
Real GDP
In this formula, nominal GDP is GDP valued in the current year’s price.
Real GDP in a base year scaled up by the growth rate of real GDP since the
base year.
With an estimate of real GDP, we can calculate GDP deflator by
dividing with nominal GDP. The answer will tell us that either the prices of
goods has been increased or decreased, with respect to the base year prices.

In the base year, nominal GDP equals real GDP and the GDP deflator is
100. In current year the real GDP has been increased due to growing
production and rising prices.
The red balloon for base year shows real GDP in that year. The green
balloon shows nominal GDP in current year. The red balloon for the current
year shows real GDP for the current year. To see the real GDP in current
year, we deflate nominal GDP using the GDP deflator.
Unemployment And GDP
Unemployment occurs when employed people losing or leaving their
jobs (job losers and job leavers) and from people entering the labor force
(entrants and reentrants).

Page 27 of 41
The Anatomy Of Unemployment:
People become unemployed if they:
1. Lose their jobs
2. Leave their jobs
3. Enter or reenter the labor force
People end a spell of unemployment:
1. Are Hired or recalled
2. Withdraw from the labor force
Let’s explore how much unemployment arises from the three different
ways in which people can become unemployed. The labor market flow shows
unemployment by reason for becoming unemployed. Job losers are the
biggest source of unemployment. Entrants and reentrants also are a large
component of the unemployed and their numbers fluctuates mildly. Job
leavers are the smallest and most stable source of unemployment.
Types Of Unemployment:
Unemployment is classified into three types that are based on its causes.
These are:
 Frictional
 Structural
 Cyclical
First two types of unemployment belong to normal labor turnover or due
to technological change or advancement. The third type of unemployment
directly belongs to country’s economic cycle. Let’s analyze the same.
Cyclical Unemployment:
Cyclical unemployment is the fluctuating unemployment that coincides with
economic / business cycle. Cyclical unemployment is a repeating short-

term problem. The amount of cyclical unemployment increases during a
recession and decreases during and expansion.

The diagrams illustrate the cyclical unemployment in an economy.
 Part (a) shows the fluctuations of Real GDP around “Potential GDP”.
 Part (b) shows fluctuations in unemployment rate around a line labeled
“Natural Rate of Unemployment”.
The Natural rate of unemployment is the unemployment rate when there is
no cyclical unemployment or equivalently, when all the unemployment is
frictional and structural. The divergence of the unemployment rate from the
natural rate is cyclical unemployment.
In the figures the unemployment rate fluctuates around the natural rate of
unemployment, just as real GDP fluctuates around potential GDP. When the
unemployment rate equals the natural rate of unemployment, real GDP is
greater than potential GDP. And when the unemployment rate is greater than
natural rate of unemployment, real GDP is less than potential GDP.
It has been clearly seen that the unemployment rate fluctuates with the
real GDP. When real GDP decreases the unemployment rate automatically
increases, and when the real GDP increases the unemployment rate
decreases. As the real GDP shows the performance of an economy, so the
increase in real GDP creates more employment opportunities in the labor
market. On the other hand the decrease in real GDP increases the
unemployment in the economy.
Economic Development And GDP
Economic Development involves growth in the economic wealth (can be
measure through GDP) of an economy. Government policy in many countries
generally aims for continuous and sustained economic growth, so that their
national economics expand and become more developed. A less developed
economy has a low level of economic development. Almost ninety percent
(90%) of the world population lives in less developed economies.
Development objectives therefore tend to include producing more necessities
(goods) as food, shelter and health-care, and making sure they reach more
people in need raising standards of living and expanding economic and social
choices.
However, different countries and even different regions with in the
same countries in the world today are at very different stages of economic
development. The countries with low GDP are considered less developed and
the countries with high GDP are supposed to be developed.

Page 30 of 41
Developed Economies:
A developed economy is generally thought of as having large modern
farms, many firms of different sizes producing and selling a variety of goods
and services, a well-developed road and rail network, modern communication
systems, stable government and a relatively healthy, wealthy and educated
population. Developed economies are also sometimes called industrialized
nations, but this is despite the great majority of their output, income and
employment now being created by their service sectors rather than
manufacturing industries.
However, according to the United Nations there is no general rule for
designating regions or countries as developed or developing, but the standard
of living of the people of the countries.
Developing Economies:
A less developed economy has a low level of economic development.
Farming methods are poor, sometimes providing scarley enough food for a
rapidly growing population to eat. There are very few firms producing and
selling foods and services. Road, rail and communication networks are
underdeveloped and most people are poor. They live in poor housing
conditions, receive little or no education, do not expect to live to old age may
even lack access to clean water to live to old age may even lack access to
clean water. Many countries in Africa are considered less developed.
Less developed countries (LDC’s) are also called developing
economies, suggesting that overtime they are becoming a little more
prosperous, that their industrial structure is developing and fewer people are
living in extreme poverty.
However, not all less developed countries are developing. Some are in
fact experiencing negative economic growth, meaning that incomes are falling
and levels of poverty, malnutrition and disease are rising. For example
between 1995 and 2004 the real GDP of Zimbabwe fell by forty percent
(40%). In contrast, some countries are developing rapidly, such as same
Eastern Europe countries such as Armenia, Georgia, but they have yet to
display the full range of characteristics of modern developed economies.
These are often grouped under the headings emerging economies or newly
industrialized countries.
Reasons For Low Economic Development (GDP):

Page 31 of 41
There are number of reasons suggested for why some economies have
remained less developed than others.
An Over-Dependence On Agriculture To Provide Jobs And Incomes:
More people in less developed economies work in farming than in
industry and services compared to developed nations. Many produce
only enough food for themselves and their families, to live on and very
little surplus they can sell to earn money. In some areas there has been
over farming which means the land is no longer any good for growing
corps. Failures of rains to arrive in some areas due to global climate
change have also meant crops can no longer be grown for people to
survive.
It is the main reason for low economic growth or low GDP of different
countries.
Domination Of International Trade By Developed Nations:
It is argued that rich nations have exploited many poorer nations by
buying up their natural resources and the food crops they produce at
very low prices, and then using these resources to produces goods and
services which they export back to the same less developed countries
at much higher prices.
Further, many rich countries have protected their own mining and
agricultural industries by paying them subsidies. These subsidies have
increased the global supply of these products and forced down world
prices. Producers in less developed countries have not been able to
complete and as a result, they lost sales, incomes and jobs.
Lack of Capital:
While incomes remain low in many less developed countries, they have
little can invest in building factories and the purchase of machinery and
equipment to develop an industrial base. Without these capital goods
less developed countries will not be able to produce more of the goods
and services they need and which they could also export to earn money
from overseas trade.
Insufficient Investment in Education, Skills and Healthcare:
Many people in many less developed countries do not have access to
basic education, training and healthcare which can help them become

Page 32 of 41
healthier, more productive and more innovative workers. Better
education about family planning may also help to reduce birth rates and
improve living standards.
Low Levels of Investment In Infrastructure:
Road, rail and communication networks are often poor in many less
developed countries. This poor infrastructure makes travel and access
and the sharing of information to the rural areas very difficult.
Lack Of Efficient Production And Distribution For Goods And Services:
Many less developed countries lack industries and services. If incomes
are low there is little incentive for businesses to setup different shops
and retail centers. If transport is difficult outside of cities then people
from rural areas cannot travel to cities to shops, and it is also difficult
to take goods and services to rural communities. If workers are
uneducated and lack skills then industry may be unable to employ them.
High Population Growth:
Many underdeveloped countries have rapidly expanding populations
because birth rates remain high. This means available goods and
services have to be shared among more and more people overtime.
Other Factors:
Unstable and corrupt governments, and wars with neighboring
countries or between different tribes or religious groups, have often
blighted the development of some less developed countries. Money that
could have been used to invest in economic development has in some
cases been misused by corrupt officials or squandered on buying arms
and fighting wars.
Development Indicators And GDP
The most commonly used indicators of development and living
standards in different regions and countries in the world.
Gross Domestic Product (GDP) Per Capita:

Page 33 of 41
Gross Domestic Product (GDP) per capita or average income per
person is the most commonly used comparative measure of development.
Developed countries tend to have relatively high GDP per capita. In 2005,
Bermuda had the highest GDP per capita of US $ 69,900.
However, GDP is a narrow measure of economic development or
welfare in a country. For example, it does not take account of what people
can buy with their incomes, access to health and education, or other non-
economic aspects such as the amount of political and cultural freedom people
have, the quality of their environment, or level of security against crime and
violence.
Calculating average GDP of persons also tells us nothing about how
incomes are distributed between populations. For example, consider China
has a rapid economic growth and it had increased the number of millionaires
in the country almost 250,000 by 2006, but still around 47% percent of the
Chinese population had to survive on less than $2/= per day, with almost 17
percent on less than $ 1 per day.
Similarly, Saudi Arabia has a reasonably high income per head, around
$13,100/= in 2005, but most the wealth in the country is held by less than 3
percent of the population.
But even within highly developed countries such as the US there are
still big disparities rich and poor people. For example, in 2005 around 9
percent of us households had an annual income of $ 10,000 or less compared
to 6 percent of households with $ 150,000 or more.
Other countries such as Equatorial Guinea, Brunei or Triniland and
Tobago also have relatively high average incomes but are generally not
considered developed because their economies depend so much on the
production of oil. These countries also have very unequal distribution of
incomes. For example, in 2005 average income in Trinidad and Tobago was
$16,800/= but 39% (percent) of the population lived on less than $2/= per r
day.
Economic Indicators Other Than GDP:

Page 34 of 41
Population On Less Than $1 Per Day:
A better measure of level of poverty in a country is the proportion of
people living on very low income, usually $1 or $2 per day. In 2002,
around 19 percent of the population of developing economies was
estimated to be living on less than $1 per day. However, even in
developed regions some 6 percent of the population in 2005 still lived
in slum condition.
Life Expectancy At Birth:
People in developed countries tend to live longer than people in less
developed countries because they tend to have better standards of
living access to good food and healthcare.
Life expectancy from birth is therefore a good measure of economic
development in a country or region. On average, a bay born in the
developed countries in 2005 could expect to live to seventy five (75)
years of age, while a baby born in less developed world expect could
expect to live around Sixty Six (66) years. However, in some of the
poorest countries in Africa, average life expectancy from birth is less
than forty two (42) years.
Other health-related indicators of economic development include baby
and mother mortality rates, the proportion of children and adults
receiving inoculations against diseases, and death rates for various
diseases including tuberculosis and HIV / AIDS.
Adult Literacy Rate:
A good measure of education provision in an economy is the proportion
of the adult population that is able to read and write. For example, most
adults can read and write in developed countries such as the US,
Canada and those in Europe. In contrast, in 2004 only around 1 in 3

Page 35 of 41
adult living in developing countries such as Chad, Equatorial, Guinea,
Niger and Sierra Leone could read and write.
Other education-related indicators include school and college
enrolment and completion rates among children and young people.
Access To Safe Water Supplies And Sanitation:
Clean water is a necessity and safe, clean sanitation can help stop the
spread of diseases. These are generally available services to most
people living and working in developed countries.
Yet, only around half of all people in developing regions had access to
good sanitation in 2004, and just 80% percent to a safe and sustainable
water source. Access to improved is particularly poor in rural areas in
developing countries with only thirty three percent (33%) of rural
population having access compared to seventy three percent (73%)
living in the cities and urban areas.
Ownership Consumer Goods:
low incomes and the lack of an efficient production and distribution
system of goods and services in many less developed economies means
ownership of consumers goods such as washing machines, cars,
telephones and personal computer is low as compared to many
developed countries.
Proportion Of Workers In Agriculture Compared To Industry Or
Services:
As compare to the developed countries, most people are working in
agriculture sector.
Human Development Index:
To make international comparisons of economic development a little
easier the United Nations compiles the human development Index
(HDI). It combines a number of development indicators into one index
with a maximum possible value of 1. Changes in the index over time

Page 36 of 41
can therefore show whether a country has improved or reduced the
economic well-being of its people in terms of their:
 Standard of Living, as measured by gross domestic product (GDP)
per capita.
 Access to education and knowledge, measured by the adult literacy
rate and school and college enrolment rates.
 Health, Diet and Life Style, measured by life expectancy at birth.
The World Human Development Index Values:
Countries can be ranked by their HDI.
High: 0.800 > 1.00
Medium: 0.500 > 0.799
Low: 0.300 > 0.499
In 2004, Norway had the highest HDI of 0.965 and Nigeria in
Africa the lowest at just 0.311. Countries with an HDI equal to or
greater than 0.800 are generally thought to have high human
development, while those with an index value less than 0.500 are
considered to have low human development. The regions and
countries of the world classified as developed, developing and
less developed according to their HDI value.
Human Poverty Index (HPI) by United Nations (UN):
The UN also used a Human Poverty Index (HPI) to rank developing
countries and developed countries. The indices for developing
countries (HPI-1) and developed countries (HPI-2) each combine a
number of measures for economic hardship.
HPI-1 Developing Countries:
o Probability at birth dying before the age of forty (40),
o Percentage of people unable to read or write,
o Population below income poverty line,
o Population without sustainable access to an improved water
source,
o Proportion of underweight children.

Page 37 of 41
HPI-2 Developed Countries:
o Probability at birth of dying before the age of sixty (60),
o Percentage of people unable to read or write very-well,
o Population with less than fifty (50) percent of average income,
o Proportion for people unemployed for 12 months or more.
In 2006, the Scandinavian countries of Sweden, Norway and Finland had
the lowest poverty values of the 17 developed countries, included in the
comparison. The United Kingdom (UK), Ireland and the United States of
America (USA) had the highest values, and therefore scored the worst in
terms of the poverty measure for developed economies.
Research Findings
From this research we find the GDP is a narrow measure of economic
development or welfare in a country. For example, it does not take account of
what people can buy with their incomes, access to health and education, or
other non-economic aspects such as the amount of political and cultural
freedom people have, the quality of their environment, or level of security
against crime and violence.
Calculating average GDP of persons also tells us nothing about how
incomes are distributed between populations. For example, consider China
has a rapid economic growth and it had increased the number of millionaires
in the country almost 250,000 by 2006, but still around 47% percent of the
Chinese population had to survive on less than $2/= per day, with almost 17
percent on less than $ 1 per day.
Similarly, Saudi Arabia has a reasonably high income per head, around
$13,100/= in 2005, but most the wealth in the country is held by less than 3
percent of the population.
But even within highly developed countries such as the US there are
still big disparities rich and poor people. For example, in 2005 around 9
percent of us households had an annual income of $ 10,000 or less compared
to 6 percent of households with $ 150,000 or more.
Other countries such as Equatorial Guinea, Brunei or Triniland and
Tobago also have relatively high average incomes but are generally not
considered developed because their economies depend so much on the
production of oil. These countries also have very unequal distribution of
incomes. For example, in 2005 average income in Trinidad and Tobago was

Page 38 of 41
$16,800/= but 39% (percent) of the population lived on less than $2/= per r
day.
The research reveals that the Gross Domestic Product (GDP) only
describes the wealth of an economy as whole but it does not reflect economic
wellbeing of the individuals of the country. Or, it is said that the GDP growth
of country does not provide accurate information that an increase in GDP will
guarantee to increase the standard of living of the people of the country.
It can be said that the GDP per capita is not sufficient to describe the
overall economic condition of the country. There are some other indicators
that must be considered while gauging the economic well being of a country.
Conclusion & Recommendations
From the whole discussion following conclusions has been extracted and
over and above some recommendations has been made:
The level of economic and human development in different economies
can be measured and compared using a range to indicators. Gross Domestic
Product (GDP) per capita, a measure of average income per person, is a most
commonly used economic indicator but it does not represent the economic
well-being and economic condition of whole population, due to unequal
distribution of wealth or income in many countries.
To analyze the economic well being of the people of the country, we can
use other development indicators, therefore, such as the adult literacy rate,
life expectancy at birth and the number of people earning less than 1$ per day.
Besides these, the UN defines HDI & HPI indices can be used to identify the
economic well being of the countries.
The above mentioned social economic indicators provide better
understanding about the standard of living of the individuals and it can be
easily understand that, up to what extent, an increase in overall GDP of a
country put an impact on the standard of living of the people.
The less developed economies have not to work for the size of their
economy in shape of GDP, but also have to invest in their infrastructure,
education, skills development of human and healthcare facilities. They have
to control the growth of the population through controlling the birth rate in
their counties.

Page 39 of 41
They should have to change their traditional agriculture system and have
to introduce modern technology in agriculture to increase their corps, which
not only fulfill their own needs but they can also export these and earn
income. They have to developed new base for the economy, which should be
based on industries. They can achieve this through more investment on
capital goods. The above all measures will help the less developed countries
to enhance their GDP per capita, but the true economic development will be
achieved through the human development and reduction of poverty in the
country.
