A vision into the economic structure of India
EFFECT ON DIFFERENT ECONOMIC FACTORS ON NDP(NATIONAL DOMESTIC PRODUCT)
Motivation Of The Project.The global economic structure of India is changing from the post independence era. Though it mainly relies on Agriculture in the beginning , but nowadays it relies more on other economic factors. The main objective of my project is to see how the different factors incomes impact the Net Domestic Product of Our Country and also predict some future values. Also we will see that How much the factor incomes effect NDP in the future.
Methodology for the Analysis
For the analysis we shall follow the following process:
Data Collection Data Representation
Data AnalysisBring out our Inferences
Data Collection:
For this Analysis we collected the data on factor Incomes from different websites. Some of Them are given below:
• http://mospi.nic.in / (Indian Planning Commission)• http://www.rbi.org.in/ (Reserve Bank Of India Website)• http://databank.worldbank.org/(World Bank Data Website)
Data Analysis:
For the Analysis we shall use statistical techniques like1. Time Series Analysis: This includes fitting of time series models (like ARIMA,GARCH,etc) and predicting future values through this model.2. Multivariate Time Series Analysis: This method helps in seeing the effects of the time series covariates all at a time.
Before Carrying Our Usual Analysis we have to get in aquaintance with the following terms.
Definition Of Certain Terms: GDP (Gross Domestic Product):It is defined as an aggregate measure of production equal to the sum of the gross values added of all resident, institutional units engaged in production (plus any taxes, and minus any subsidies, on products not included in the value of their outputs).It is measured in three different approaches:
GDP
Product Approach
Income Approach
Expenditure Approach
But we will use the Income Approach
• GDP: Income Approach: It is the sum of primary incomes distributed by resident producer units .It is measured as
GDP = compensation of employees + gross operating surplus + gross mixed income+ taxes less subsidies on production and imports
Compensation of employees (COE) measures the total remuneration to employees for work done. It includes wages and salaries, as well as employer contributions to social security and other such programs.Gross operating surplus (GOS) is the surplus due to owners of incorporated businesses. Often called profits, although only a subset of total costs are subtracted from gross output to calculate GOS.Gross mixed income (GMI) is the same measure as GOS, but for unincorporated businesses. This often includes most small businesses.
The sum of COE, GOS and GMI is called total factor income. Adding taxes less subsidies on production and imports converts GDP at factor cost to GDP(I).Total factor income is also sometimes expressed as:
Total factor income = employee compensation + corporate profits + proprietor's income + rental income + net interest
Definition of certain terms
Definition of certain terms
NDP:The full form of NDP is National Domestic Product. It is the gross domestic product (GDP) minus depreciation on a country's capital goods.Net domestic product accounts for capital that has been consumed over the year in the form of housing, vehicle, or machinery deterioration. The depreciation accounted for is often referred to as "capital consumption allowance" and represents the amount of capital that would be needed to replace those depreciated assets.If the country is not able to replace the capital stock lost through depreciation, then GDP will fall. In addition, a growing gap between GDP and NDP indicates increasing obsolescence of capital goods, while a narrowing gap means that the condition of capital stock in the country is improving. It reduces the value of capital that is why it is separated from GDP to get NDP.
Factor Income Covariates:It includes Agriculture ,Manufacturing ,forestry ,logging , mining &fishing, Construction ,Electricity ,gas & watersupply, Finance, Real Estate, Insurance & Business Services, Social & Personal Services, Trade ,Hotels ,Transport & Communication.

From the diagram given above we have the following observations:
• Here the Agriculture share decreases and falls steeply from 1996 till 2007 after wards becomes stable• The Forestry, logging and fishing share decreases suddenly after 2000-2003 and after that again
rises.• In case of Mining & Quarrying the share falls and rises quite frequently but it has an increasing
trend.• The manufacturing industry has steep rise and falls in the end finally falls steeply after 2007.• In case of Electricity, gas and water supply we see an increasing trend till 2000 and a decreasing
trend after 2000. • In case of Construction the percentage share curve has a steep rise so we can say that construction
industry has an increasing impact on Indian Economy .• Though there is a steep depression from the years 1990-2000 ,the trade ,hotels , transport and
communication industry has recovered from this phase and now has a great position. • The Banking , Finance ,Insurance , Real Estate and Business Services percentage share here
increases and we can interpret it by saying people are using banks and are interested in financial services which is a very good sign.
• In case of public administration , defence , social and personal services also we can see an upward trend with a boom in the year 2000.
Interpretation from the diagrams:
Analysis Of The Data
As far as the analysis is concerned we shall firstly use the usual time series analysis. We shall do it in the following steps:
Step-1Test for
stationarity using Augmented
Dickey Fueller Test
Removing Stationarity:We
shall remove stationarity by
differencing
Step-2Fitting ARMA
Model: We Shall Fit ARMA model on the data and check the goodness of fit
by AIC.
We shall check for the
volatility of the residuals
Step-3 Check For Volatility
If Volatility presents we shall
go for trhe GARCH modell
Step-4 PredictionUsing the given
time series predict for the next 5
years.

A Multivariate Approach to the Analysis
A multivariate analogue to our current analysis is to use the VAR model.The usual Vector Autoregressive model (VAR) of order p is given below:
𝑿 𝒕=𝑨𝟏∗𝑿 ( 𝒕−𝟏 )+𝑨𝟐∗ 𝑿 (𝒕−𝟐 )+…+𝑨𝒑∗𝑿 ( 𝒕−𝒑 )+∈𝒕
Where is the vector of time series variables and ’s are coefficient matrices.
A Second form of the model is the Error Correction Model which is given below:
+
Where π=G*H and H is the cointegrating matrix
Cointegration and VAR model fitting
Here we perform Johansen’s Test which gives the following results:

Since the rank of π is 8 <10 we can say that the model has unit roots and we have to fit an EC Model with Co integrating Matrix.

Forecasted percentage shares
• We can see that the share in the Agriculture decreases till 2015 ,rises from there and attains maximum in 2017 after which it again decreases.
• We see that Mining ,Forestry ,Manufacturing , Construction ,Trade & Hotels & Transport industry have a decreasing percentage shares and the government should look upon it in future
• We also find out that Financial Services and Electricity, Gas and water supply has an increasing percentage share and government should invest upon these factors as they provide them more incomes.
Findings from the forcasted figures:
• Here we have data on factor incomes like Agriculture , Forestry & logging & fishing , Mining & Quarrying ,Manufacturing Electricity , gas and water supply ,Construction ,Trade,Hotels,Transport ,Banking ,Finance ,Insurance , Real Estate and Business Services Public administration and Defence,social and personal services and we have to study its effects on NDP and see how these are effecting NDP in future
• Here we see though Agriculture was the main determinant of Income at the first few years but later we find that other factors have more effect at the succeeding years and these play important roles in future.
• We see that Public administration and Defence , social and personal services , Banking , Finance , Insurance, Real Estate and Business Services, Construction ,Mining & Quarrying , Electricity , gas and water supply has an increasing trend though they are harmonic rising in some years and falling in some years
• We see the remaining factors have a decreasing percentage share of incomes.
• We have fitted ARMA Models on the entire data see that the fitting is good except for some points
• We have tested for Volatility factor and find that we have to fit GARCH Model on the data
• Here the most appropriate model is the GARCH (1,1) model and see that the residuals after fitting is not volatile
• We have used Augmented Dickey Fuller test before ARMA fitting to remove trend component by finding the no of unit roots, Portmanteau tests for diagnostic checking (goodness of fit of the ARMA model),Lagrange's test for the volatility checking.
• In case of ADF test we found the presence of unit roots in all the covariates and have to difference to remove trend .
• We have also fitted a Multivariate model to see the effects of the covariates at the same time on different years. Since Johansen’s Test suggests the presence of cointegrating effects we used Error Correction Model form of the usual VAR model having cointegrated effects(i.e Cointegrating matrix)
• Now we get predictions from the fitted model and can infer that under the continuing conditions the share in the Agriculture decreases till 2015 ,rises from there and attains maximum in 2017 after which it again decreases. Mining ,Forestry ,Manufacturing , Construction ,Trade & Hotels & Transport industry have a decreasing percentage shares and Financial Services and Electricity, Gas and water supply has an increasing percentage share.
