GNP as a measure of Economic
Welfare Since goods and services satisfy wants, GNP has been
often used as a measure of economic welfare of thepeople
Recent economists believe that NY or GNP (as it isusually defined) cannot be used as a satisfactory
measure
Adjustments, both in form of additions andsubtractions have to be made to the aggregate NY

Things that should be added LEISURE : People enjoy leisure as much as goods and
services. If the average working hours are reduced, itmay reduce NY or National Output but the welfare ofthe people will increase
NON-MARKETED PERSONAL SERVICES : Like
services of a housewife. Services rendered to oneselflike gardening, painting your own house, etc.

NEW - Not a true indicator of
economic welfare
4) Improvement in Quality of product NY does
not reflect this
5) Method of Production If NY is increased bymaking the workers work for longer hours or by
introducing labour-saving machinery (causingunemployment)

Human Development Index (HDI) Human development is the process ofenlarging
peoples choices as well as raising the levels of wellbeing achieved
The United Nations Development Programme(UNDP) prepared the HDI in 1990
HDI focuses on How the people of the country arefaring rather than How much a nation is producing

Construction of HDI HDI has three dimensions:
A) Life expectancy at birth
B) Educational Attainment
i) Adult Literacy Rate
ii) Combined Gross Enrolment Ratio
C) Real GDP per capita (PPP$)

Construction of HDI Step 2: Computing Individual Indices
Performance in each field is expressed as a value
between 0 and 1 0 for worst performance
1 for best performance
Index= Actual Value Minimum Value
Maximum Value - Minimum Value

Construction of HDIA) Life Expectancy Index
For example according to Human DevelopmentReport, 2005 the Life Expectancy at birth in India in2003 was 63.3 years
Thus:
LEI = 63.3 25 = 38.3 = 0.638 85 - 25 60.0

Construction of HDI B) Educational Attainment Index : It has 2 variables
i) Adult Literacy Rate : The %age of people (agegroup 15 years and above) who can read and write. Thisis given 2/3rd weightage
ii) Gross Enrolment Ratio : No. of students enrolledat different levels of education ( primary, secondaryand tertiary). This is given 1/3rdweightage

Construction of HDI For example, according to the Human Development
Report, 2005, in India in 2003, the adult literacy ratefor age 15 and above was 61 and the gross enrolmentratio was 55
Adult Literacy Rate = 61 0 = 0.61
100 0
Gross Enrolment Ratio = 55 0 = 0.55
100 - 0

Construction of HDI EAI = 2/3 (0.61) + 1/3 (0.55)
= 0.4026 + 0.1815
= 0.5841

Construction of HDI C) Standard of Living Index or Real GDP Per Capita
Index This reflects the quality of life of people they need
resources PCI is the simplest measure of resources at the command
of the people GDP per capita is calculated at constant prices show
changes in physical production in real terms
Real PCI = GDP at constant pricesPopulation To facilitate comparison, PCI of different nations are
converted into PPP US $

Construction of HDI For example, according to Human Development
Report, 2005, per capita GDP of India was $2892 in2003
SLI = 2892 100 = 2792 = 0.71
4000 100 3900

Construction of HDI Step 3 : Calculating the HDI
A simple average of the 3 indices is to be taken
HDI = LEI + EAI + SLI
3
HDI = 0.638 + 0.5841 + 0.71
3
= 0.644

Interpreting HDI values Countries are ranked on Human Development on the
following basis:
HDI value > 0.8 High Human Development
HDI value between 0.5 and 0.8 Medium HumanDevelopment (India falls in this category)
HDI value < 0.5 Low Human Development
Out of 177 countries, India ranks 127th ( HumanDevelopment Report, 2005)
In India, Kerala ranks 1st and Bihar at the bottom
