TOKYO
India KLEMS research team
To generate time series on output and inputs in various sectors of
the economy consistent with the National Accounts.
To create a productivity database for India that would be
comprehensive.
To undertake research on India’s productivity growth at the
economy and sectoral level through creation of a database on
indicators of economic performance.
2
Consistency with NAS.
Large part of the database utilized for series construction comes from NAS and related data
series (input-output tables).
Interpolation done for constructing annual time series wherever required (labour
input, intermediate input, GVO of services sectors)
Annual Series is formed because It would help in checking consistency among different input/output series.
It would be useful for other users who require data for specific years.
Comparability is maintained in the concept used for data construction.
Objective is to get a comparable data set for India and other countries.
Choice of sector classification is such that it is by and large comparable to the
classification being used in similar studies or undertaken in other countries

GVO obtained from NAS both at current and constant prices from 1980-08.
The NAS 1999-00 series is used up to 2004-05 and then the new NAS series is spliced.
GVO for Total Manufacturing obtained by Aggregating Registered and Unregistered segments of
Manufacturing.
For 7 out of 13 industries GVO directly picked up from NAS
Manufacturing
sectors
For other 6 industries ASI ratios( for registered industries) and interpolated NSSO ratios(for unregistered
industries) are used to split output of NAS industries to concord with KLEMS industries.
Prior to 1999 GVO is not available in NAS for unregistered industries .Thus,
GVO to GVA ratios is obtained from NSSO survey reports, for 1984-85(40th Round),
1989- 90 (45th round ) and 1994-95 (51st round )
GVO to GVA ratio from 1999, is directly picked up from NAS.
Ratios are linearly interpolated between four data points 1984,1989, 1994 and 1999. and
applied to Time Series of GVA of NAS to obtain time series on GVO consistent with NAS
from 1984 -98.The ratio of 40th round is taken backward to estimate output of 1980 to 1983.
The current price estimates have been deflated using WPI deflators to obtain constant price estimates.

Major tasks in creating a Data Base on Labour
Make a Time series of Employment [number of persons]
from 1980 to 2008[A]
Prepare a Labour Quality Index from 1980 to 2008 [B]
Make a Time series of Labour Input from 1980 to
2008[=A*B]
Data sources
Employment and Unemployment Surveys 38th (1983) to
66th (2009-10) Round by National Sample Survey Office
(NSSO), and
Population Census.
11
Employment has been computed as follows:
Work Participation Rates (WPRs) by UPSS from EUS are applied to the corresponding
period’s census population of Rural Male, Rural Female, Urban Male and Urban
Female to find out the number of workers in the four segments
The 26-industry distribution of Employment from EUS is applied to the number of
workers in step I to obtain Lij for each industry where i=1 for rural and 2 for urban
sectors, and j=1 for male and 2 for female
Total persons in a year were obtained for each industry as the sum of the Lij over
gender and sectors, ΣiΣjLij
The estimates of employment for all the sectors are first obtained
for the major rounds.
Then interpolation between the two nearest major rounds has
been done for the period 1980-81 to 2008-09.
For extrapolation backward to 1980-81 to 1982-83, the interpolation of the broad
industrial classification of 32nd round and 38th round is used. So the estimates
from 32nd round are mainly used as control numbers.
12
The methodology given by Jorgenson, D.W. et. al. (1987),
Productivity and US Economic Growth, uses the Tornqvist
translog index and it incorporates all compositional changes in
the labour force; e.g. age, sex, education, etc and uses earnings*
as the weights.
But due to data limitations only educational composition of
workers has been considered in the current study.
* The use of current or real earnings does not affect the index.
The labour composition index has been computed using 5 educational categories namely :
1) up to primary, 2 ) primary , 3) middle,4) secondary and higher secondary, and 5) above
higher secondary
13
NSSO’s EUS provides earnings data mainly for regular- salaried
workers and casual workers
The issue was how to estimate earnings of self employed?
The present study has used two approaches:
First, a Mincer Wage equation has been estimated and sample
selection bias has been corrected for by using Heckman's two step
procedure – the equation is then used to get an estimate of the
earning of each self-employed person in the sample.
Secondly, earning of self employed has also been estimated from the
monthly consumption expenditure of these households.
The lower of the two alternate estimates of earnings is taken to be the
earnings of a self employed person.

Detailss
Manufacturing Sector: computations based on ASI and NSSO
Labour Share = Emoluments/GVA, computed for organized and unorganized
manufacturing separately
Combined on the basis of weights of share of GVA in Registered and unregistered Manufacturing sector
Non-Manufacturing Sector: computations based on NAS, NSSO and
Estimated GVA
Labour Share = [Compensation of Employees (CE) + Labour income of Selfemployed ]/GVA
NDP at factor cost= CE+OS+MI [available from NAS]
Self-employed wages = (wage per day) * (employment in terms of number of days
employed)
Note: labour income of self employed is based on estimated wage
equations and data on consumption expenditure of such households
15
India KLEMS uses measures of capital services rather than capital stock
WHY capital services?
Accounts for the heterogeneity of various assets
o A computer is added to a truck, only after adjusting for their
differences in marginal productivities
Does it make a difference
Increasing share of fast depreciating assets, which are expected to
deliver more capital services in short time, will increase the capital
service growth rates faster than capital stock
Effect on measured TFPG: TFPG will be overestimated when measured
using capital stock, if share of fast-depreciating assets are increasing

DATA SOURCE :
National Accounts Statistics 2011,2009, 2007 and Back Series
WPI, Office of the Economic Advisor, Ministry of Commerce and Industry
Supply and Use Tables (known as the Input Output Transaction Tables) for Benchmark Years: 1978,
1983, 1989, 1993, 1998 and 2003
METHODOLOGY :
Step 1 : Concordance is done between Input Output Transactions Table and India KLEMS
industries
Step 2 : Estimates of inputs from IOTT, for 26 KLEMS industries are aggregated into Material,
Energy and Service Inputs .
Step 3: Projecting a time series of intermediate input vector from 1980 to 2008, for 26 KLEMS
Industries
Obtaining E,M , S for benchmark years :
Concordance matched between IOTT tables and study industries.
Estimates of inputs from IOTT are aggregated into E,M,S
(continued…..)
19
Obtaining E MS for intervening years :
For the Benchmark I/0 years proportions of Material Inputs, Energy Inputs, and Service Inputs in Total
Intermediate Inputs are calculated.
Similar proportions for intervening years are projected by linear interpolation of the benchmark proportions.
This gives a time series of proportions of Material, Energy and Service Inputs from 1980 to 2008
The projected input vector in has been proportionately adjusted to match this gap between value added and
gross output in NAS to maintain consistency with NAS
Detailss
Step 5: Constructing Deflators of Materials, Energy and Service Inputs for 26 India KLEMS Industries
separately
o
Deflators are obtained for each of the 115 commodity inputs( WPI deflators for Energy, Material inputs, GDP deflator for
service inputs)
o
Deflators obtained for different IO sectors have been combined using weights(Two IOTT has been used for this purpose 1989 and 1998. )
Step 6 : The deflators for Material, Energy and Service Inputs for each KLEMS Industry have been used to
deflate the Current prices Intermediate Input series to Constant prices
Step 7 : The time series of Intermediate Input at constant prices for 26 KLEMS industries have been
aggregated
( Tornqvist)to form higher level estimates for the broad sectors.

Interpolation of Data

Estimating employment series in our Study :
Employment is based on UPSS from 38th (1983) to 66th (2009-10) round, adjusted for population census, and
various NIC concordances with KLEMS industries.
The estimates of employment for all the sectors are first obtained for the major rounds.
For non-survey years, employment numbers are intra/extrapolated to create time series for the period 1980 to
2008
Methodology used in other KLEMS Study
Jorgenson ,Ho and Stiroh (2007)
Uses decanal Census population data, Current population survey annual demographic survey
data(sample size is about 1/10th of population Census)
First step is to scale employment data based on CPS so that economy totals equals to Bureau of labour statistics
(BLS) annual tabulation based on monthly CPS.
This scaled matrices are then taken as marginal totals to interpolate and extrapolate the Census benchmarks.
The inter censal years is derived from the nearest two censuses and made consistent with these marginal totals
The census based matrices are calibrated to the BLS in order to provide a smooth series.
Ren and Sun (2007) for China, due to data limitation starts with estimate of labour input on several benchmark
years and eventually by interpolation/extrapolation completes time series for labour input for the whole period.
Pyo et.al (2005) for Korea relies on employment tables which is published as a supporting table to IO ,
available at an interval of 5 years and uses interpolation/extrapolation to create the employment series.
22
Although annual series is being constructed, conclusion drawn are based on trend growth rates which are
not much sensitive to the assumption underlying interpolation of input-output coefficients.
Methodology used in other KLEMS studies
Jorgenson, Ho and Stiroh (2007) for US uses official benchmark Inter Industry
transaction tables and generates a time series of inter industry transaction tables for two
sub periods : 1977 -82 and 1983-2000 . To make the two sets comparable 1977-82 tables
are adjusted to the new set by iterative proportional fitting (RAS) method.
Timmer et.al ( 2010) for EU KlEMS countries uses shares in intermediate inputs from
NA. IO tables as available at regular intervals , which necessities interpolation and
assumption of constant shares to build time series of E,M.S
Ren and Sun (2007) for China , uses the current price benchmark I/O tables
1981,1987,192,1997 and constructs a time series of Use tables based on the adjusted
comparable benchmark tables using interpolation .
Pyo et .al (2005) for Korea, uses benchmark I/O tables published by Bank of Korea and
estimates time series of input output by interpolation of I/O coefficients
Liang (2005) for Taiwan , have constructed the time series of value shares of each
intermediate inputs by interpolating between the IO tables available in benchmark years

Construction of Time Series on Gross OutputMETHODOLOGY
METHODOLOGY :
STEP 1 Measuring Gross Output of Agricultural Sector: (KLEMS Industry No:
1)
NAS provides nominal and real GVO series for
• Crops and plantation
•Animal Husbandry
•Forestry and Lodging
•Fishing
Aggregating GVO of these 4 subsectors we derive GVO of Agricultural Sector
Step 2Measuring Gross Output of Mining & Quarrying and
Construction: (KLEMS Industry No: 2and 17)

Jorgenson’s Approach
-The methodology given by Jorgenson, et al (1987) uses the Tornqvist
translog index and it incorporates all compositional changes in the labour
force; e.g. age, sex, education, etc and uses earnings* as the weights.
- But due to data limitations only educational composition of workers has
been considered in the current study.
* The use of current or real earnings does not affect the index.
The labour composition index has been computed using 5 educational catagories namely :
1) up to primary, 2 ) primary , 3) middle,4) secondary and higher secondary, and 5) above
higher secondary

Some Key Findings
Labor productivity growth has been computed by as the difference
of growth rate of real value of gross output and growth rate of
persons employed.
The median for the 26 industries is 4.1 percent per annum.
Labor productivity growth rates vary widely across industries for
the given periods. Post and Telecommunication, Electrical and
Optical equipment, Electricity Gas and Water, textile and Leather
products are some of the industries which record high rates of
growth in labor productivity.
As regards the sources of labor productivity growth, we find that
the median contribution of intermediate inputs is 1.8 percentage
points out of 4.1 percentage points followed by 1.1 percentage
points by capital deepening.

Existing measures of capital in India
◦ NAS estimates of gross and net capital stock
GFCSt = GFCFt + GFCSt-1 - GFCFt-L ; t > L; GFCSt = GFCFt + GFCSt-1 ; t<=L;
GFCS=Gross fixed capital stock; GFCF=Gross fixed capital formation; t=year; L =
average life time of asset (one-hoss-shay depreciation; light bulb depreciation)
NFCSt=GFCSt - CCFCt ; NFCS=Net fixed capital stock; CCFC=cumulative
consumption of fixed capital, where consumption of fixed capital is measured as
GFCSt/L.
Past academic attempts
◦ TFPG studies, in particular in organized manufacturing sector used aggregate
capital stock using perpetual inventory method, disregarding the asset
composition (e.g. Ahluwalia, 1986 and 1991; Goldar, 1986; Rao,1996; Balakrishnan and
Pushpangadan, 1994; Das, 2004)
◦ Often no depreciation, or a common depreciation rate (e.g. Goldar, 1985, Timmer,
1999, but still capital stock) for all assets is used
◦ Timmer, 1999 shows an overestimation of capital stock of more than 50% in other
studies, when no allowance for depreciation is given

Co-existence of multiple vintages
=Different vintages have different marginal productivities
=Each generation of capital assets will embody different levels of
technology, and are therefore not homogenous
And
Heterogeneity of Capital Assets
=Aggregating computers, machines, trucks and many more!
=Cambridge Controversy (aggregating money value vs.
impossibility of aggregation)
Back
55
Perpetual Inventory Method
◦ Aggregate money value of different assets (e.g. value of computers + value
of trucks) of different vintages (e.g pentium 3 + pentium 4)
Problems
Aggregation of vintages:
◦ Use efficiency weights (under the assumption that newer vintage embody
newer technology).
◦ Takes account of differences in vintages to some extent, given that
depreciation and asset prices are properly measured
Aggregation across assets:
◦ Aggregate money value of different assets. Takes no account of asset
heterogeneity
Back
56
Capital services using Jorgenson methodology:
Asset-wise capital stock growth rates are aggregated using compensation shares of each
asset as weights, so that differences in marginal productivities of these assets are
incorporated
Capital service growth rates are arrived at as the weighted growth rate of individual
capital stock, where the weights being the compensation share of each asset type, i.e.
ln K j

◦ The study provides new estimates of capital input for productivity analysis in Indian
economy and 26 sectors for the period 1980-2008.
◦ Compared to conventional measures of capital stock, measure of capital services are
theoretically pertinent, as it takes asset heterogeneity into account, while aggregating
capital services.
◦ This is of particular significance, given the importance of equipment investment for
economic growth, which is growing faster in the Indian economy.
◦ Measures of capital services are increasingly preferred in the international academic
sphere, over the conventional measures of capital stock.
◦ This study makes an important contribution by providing estimates of capital
services.
• Capital services grow faster than capital stock in almost all sectors, reflecting the
increasing share of equipment capital
• This will have serious implication for productivity measurement, as conventional
measure of capital stock will overestimate the contribution of TFPG to GDP growth.
65
The measure of capital service we use is constructed under somewhat
unrealistic neoclassical assumptions, and are subject to any criticisms to
standard neoclassical assumptions, that equate marginal cost with prices.
In addition, any limitations associated with the measurement of capital
stock using the perpetual inventory method, such as the assumption of
geometric depreciation rate and imputation of initial stock are also
applicable. This is because the estimation of the flow of capital services are
assumed to be proportional to capital stock at individual asset level.
At the individual asset level, the assumed depreciation rates are lower
than many cross-country studies and databases (e.g. Easterly and Levine,
2001; Penn World Tables, EU KLEMS). The assumed low depreciation might
overestimate our measure of capital input growth rate. This issue will be
addressed in the further revisions of the data.

METHODOLOGY :
Step 2: Obtaining estimates for Material, Energy and Service Inputs for 26
India KLEMS Industries, for benchmark years
Estimates of inputs from IOTT, for 26 KLEMS industries are aggregated into
Value of Energy Inputs
Value of Material Inputs
Value of Service Input
Value of Total Intermediate Inputs (summation of the above three)
Thus, for each benchmark year, estimates are obtained for Material, Energy
and Service Inputs in 26 India KLEMS Industries.

KLEMS Sector 24, Public Administration and Defense- A Special Case!
IOTT gives no information on Inputs for this Industry. The estimation of inputs for
Public Administration for years prior to 1999 has been done using Tables on ‘Final
consumption expenditure of Govt. administrative departments’ published in NAS and
for years post 1999, the ‘SNA’ tables have been used.
Statement 27, Final Consumption Expenditure of Administrative Departments, in
NAS provides figures on net Purchase of Commodities, by Administrative department.
This figure is taken for benchmark IOTT years 1978, 1983, 1989, 1993 and 1998
Statement 67, Cross Classification of Output/Value Added by Kind Of Economic
Activity, in SNA Table provides figures on Intermediate Consumption in Public
Administration and Defense, for the year 2003.
For each benchmark year thus, the total intermediate consumption has been distributed
across all IO sectors, using the GFCE proportion to get Material, Energy and Service
Inputs.

Step 6: Constructing Deflators of Materials, Energy and Service Inputs for 26 India
KLEMS Industries separately
Deflators are obtained for each of the 115 commodity inputs(each row of the IO
Matrix)
WPI for the period 1980 to 2008 is taken from Office of the Economic
Adviser, Ministry of Commerce and Industry.
For Electricity as an input entering into the production process of an
industry, depending on the nature of economic activity, the right price of
electricity has been chosen.
For Service Inputs, since WPI is not available hence implicit GDP deflators
from NAS are used.
Deflators obtained for different IO sectors have been combined using weights.
The weights are based on the column of the relevant KLEMS industry in the
IO table.
Two IOTT has been used for this purpose - 1989 and 1998.
The price series based on 1989 table has been used from 1980 to 1993 and
the 1998 table has been used for the price series from 1993 to 2008.
Once the two series have been formed, these have been spliced.
Back
76
Step 7 Computing Time Series on Intermediate Input for 26 India KLEMS
Industries from 1980-2008, Constant prices
The deflators for Material, Energy and Service Inputs for each KLEMS
Industry have been used to deflate the Current prices Intermediate Input
series to Constant prices.
Step 8: Computing Time Series on Intermediate Input for Broad Sectors of
Indian Economy from 1980-2008, Constant prices
The time series of Intermediate Input at constant prices for 26 KLEMS
industries have been aggregated to form higher level estimates for the broad
sectors.
Thus a time series of Intermediate Input at constant price is constructed for
KLEMS 26 Sectors and Broad Sectors.
Back
77
For certain INDIA KLEMS Sectors, there are huge year to year fluctuations in
Intermediate Inputs, especially in Energy Input and Service Inputs. This is primarily
because, in certain IOTT years, there is an abrupt increase or decrease in the
proportion of an input going into a KLEMS industry. Therefore such fluctuations have
been smoothened by excluding the particular year in which there is an unusually
high/low IOTT Input Proportion going into an Industry’s Production process.
The KLEMS sectors where such adjustment has been done are as follows:
Textiles, Textile Products, Leather and Footwear
Wood and Products of Wood
Machinery, nec
Manufacturing, nec; recycling
Electricity, Gas and Water Supply
Trade
Health and Social Work
Public Administration and Defense; Compulsory Social Security
Education
Other Services
Back
78
The Intermediate Input Series at constant prices is not consistent with the
Gross Output Series at Constant Prices i.e. the following equation does not
hold true at constant prices.
‘E + M + S’ at Constant Price = ‘GVO – GVA’ at Constant Price
However only for Agriculture since NAS gives double deflated value, hence the
Intermediate Input series is consistent with the Output series in constant
prices.

The labour income and capital income out of gross value added, is further
distributed into income share of labour in gross output and income share of
capital in gross output.
The individual shares of intermediate inputs, that is, Material, Energy and
Service in Gross Output is first calculated.
Thus we get the share of labour, capital, material, energy and service in Output.

There have been a good deal of research on productivity growth of Agriculture
sector.
Such studies include: Sivasubramaniam (2004), Pratt, Yu and Fan (2009) , Fuglie
(2008) Evenson et al (1999) , Bosworth, Collins and Virmani (2007), and Bosworth
and Maertens (2010)
Variation in results for different periods but all support the following broad
conclusions :
TFP growth faster in 1980’s to 1970’s. (ranges between 1.5 % to 2% per annum in
1980’s)
In 1990’s TFP growth is lower ( ranges between .7% to 1.2% per annum)
Growth rates of TFP further diminishes in 2000’s
Back
96
S. SivaSubramaniam(2000) :
Study distinguishes between TFP of residential and non residential sector.
Non residential is further subdivided into Sector A :Agriculture, Forestry and Fishing and
Sector Non A : non agriculture excluding dwellings.
Followed Denison methodology and gave a detailed account of data source and methods:
Data sources for Agriculture sector :
Variables: : Labour, GFCS, Inventories, Land
Coverage: 50 years period from 1950 to 2000
Land : Net cropped Area+ fallow land ( Ministry of Agriculture)
Cost shares : .56 to.45 for labour, .17 to .34 for GFCF, .045 to .01 for inventories and .25 to
.19 for land.
Back
97
Evenson ,et al (1999)
TFP measured as ratio of index of Aggregate output to an index of aggregate inputs .
Study uses Tornqvist –Theil TFP index
Estimates of TFP only for production crops ( 5 major and 13 minor) across 13 states and do not
include livestock.
Data sources for Agriculture sector
Variables : Unirrigated land, irrigated land, human labour, animal labour, tractors, fertilizer and
irrigation capital.
Land : Data form Directorate of Economics and statistics; Agriculture Situation report.
Farm harvest prices , Agricultural wages from Directorate of Economics and Statistics
Labour: decennial population census
Tractors : Interpolated data from census
Fertilizer : fertilizer statistics ; fertilizer association of India.
Factor shares from micro level studies

Apart from KLEMS Land is included as an input in Agriculture
Two alternative definition of land input for agriculture sector.
Definition 1: Land input= Net Cropped Area + fallow land
Definition 2: Land input= Gross Cropped Area + fallow land
As National Accounts Statistics (CSO) includes irrigation as part of capital stock, we have excluded land quality
as this will amount to double counting.
