Value-added disaggregated social accounting matrix for the Indian economy of the year 2007–2008


India is pioneer in constructing the social account matrices for its economy for various years, but limited efforts have been made to construct a SAM for India with detailed description about types labour input employed in various economic activities and subsequently the distribution of labour income across various households groups. To bridge this gap, we have constructed a 78-sector SAM for India which takes into account 48 types of labour input for economic activities and 80 types of households classes in India. Integrating the existing input–output database of the year 2007–2008, a 78-sector SAM of the year 2007–2008 and unit-level data published by National Sample Survey Office of India. This SAM differs from the existing 78-sector SAM in terms of its sectoral classification and especially the level of disaggregation of value-added and households account. Further, in this study we have illustrated some applicability of this SAM in analysing income inequality across various social groups of households in India and their contribution to the national income of India. It is observed from this SAM that the rural other social category of households constituted 17% of total population in India and contributed 13% of its net national income, whereas the special social category households of rural areas (SC, ST and OBC) contributed significantly lower in India’s NNP than their share in population. Hence, these categories of households in rural India remain unproductive than the other social category of households. Contrary to this fact, the urban counterparts of these social groups of households are more productive in India. We have also estimated the Gini coefficients corresponding to each social group of households as a measure of level of income inequality. Further, the SAM multiplier model has been applied to observe the impact of agricultural growth on rural income and income equality. The estimated Gini coefficients revealed the facts that the growth in paddy crops will lead to high increase with low income inequality among the SC and ST households, whereas for the OBC and other category households the same phenomena is observed corresponding to livestock sector.


The Indian economy is growing fast since the introduction of the economic reform process has been recognized by policy analysts and policy makers (Kotwal et al. 2011; Ahluwalia 2002). However, the poverty and income distributional implications of economic policy reforms have often been the subject of policy debate in India. In order to examine such implications of economic policy reforms, an economy-wide database such as a social accounting matrix (SAM) that includes a detailed component of household income distribution of different socio-economic groups is required. Furthermore, an economy-wide model based on such a detailed database is required to examine the impact of policy reforms on different socio-economic groups in the Indian economy. Therefore, the purpose of this paper is to outline a detailed framework for the construction of an Indian SAM for the year 2007–2008. The main contribution of the proposed SAM is the disaggregation of the value-added component of each sector in Indian economy in a detailed manner.

The structure of the rest of the paper is as follows. The section 2 provides a brief overview of a SAM and its historical evolution. The section 3 describes steps involved in extending the exisitng SAM of the year 2007-08 into a value added disaggregated SAM of the same year for India. Subsequently the consistency of the SAM has been validated using data on key macro economic indicators and this is described in the section 4. The section 5 briefly described the application of this SAM in analysing income inequality in India. In this section also we have applied the SAM multiplier analysis to assess the impact of sector specific growth on income inequality across various social groups. At the end the section 6 concludes this paper by citing the key limitiation of this SAM as well.

A brief overview of SAMs and historical evolution of compiling SAMs for India

A social accounting matrix is simply defined as a single-entry accounting system whereby each macroeconomic account is represented by a column for outgoings (payments) and a row for incomings (receipts) (Hayden and Round 1982). It is represented in the form of a square matrix with rows and columns, which brings together data on production, income generation, consumption, investment and external transaction. In a SAM, incomings are indicated as receipts for the row accounts in which they are located and outgoings are indicated as expenditure for their column accounts. Since all incomings must be, in a SAM, accounted for the outgoings, the total of rows and columns must be equal for each account. Taylor and Adelman (1996) sees the SAM as a tabular presentation of the accounting identities, stating that incomings must be equal to outgoings for all sectors of the economy.

The SAM is a data system, including both social and economic data for an economy. The data sources for a SAM come from input–output table, national income statistics, and household income and expenditure statistics. Therefore, a SAM is broader than an input–output table and typical national account, showing more detail about all kinds of transactions within an economy. However, an input–output table records economic transactions alone irrespective of the social background of the transactors. A SAM, on the contrary the national accounts, “… attempts to classify various institutions to their socio-economic backgrounds instead of their economic or functional activities” (Chowdhury and Kirkpatrick 1994: 58).

The history of SAMs goes back to Stone’s (Stone 1962) pioneering work for the UK. Since the 1970s, Pyatt, Thorbeck and their associates (Pyatt and Roe 1978; Thorbecke and Jung 1996; Pyatt and Round 1979) have extended Stone’s work to developing countries to address distribution issues of economic reforms. As a result, early SAMs were constructed for a number of developing countries such as Sri Lanka (Pyatt and Round 1979), Malaysia (Chander et al. 1980), Botswana (Hayden and Round 1982) and Indonesia (Thorbecke and Jung 1996). As summarized by Hayden and Rounds (1982), three principle motivations underlie compilation of SAMs. Firstly, a SAM assists us to bring together different sources of information to describe the main structural characteristics of an economy. Secondly, a SAM provides a proper accounting framework to identify the link between income distribution and different sectors of an economy. Thirdly, a SAM provides a detailed and comprehensive database to construct a computable general equilibrium (CGE) as a benchmark database.

The popularity of SAM has also been recognized in many South Asian countries such as Sri Lanka (Bandara and Kelegama 2008), Pakistan and India (Pal et al. 2012). India was an early leader in compiling SAMs and developing models based on SAMs. To our best knowledge, Sarkar and Subbarao (1981) of National Council of Applied Economic Research (NCAER) constructed the first SAM for India way back in the 1980s, which provided the consistent database for their computable general equilibrium (CGE) model. Subsequently a number of SAMs were constructed over the years for Indian economy by different researchers. Table 1 provides a brief overview of the published SAMs and their salient features.

Table 1 Stylized facts of SAMs of India.

It is apparent from the above table that most of the SAMs for India have taken into account the aggregate labour and capital as primary factor input. But the labours are paid according to their level of skill and wage rates also vary across sectors. Again the factor income is key source of income for the households; disaggregation of labours and households will give detailed picture about the income distribution and source of income inequality in India. For example, the income distribution across different social groups of households depends on the amount of capital they are endowed with and the level of skilled labour they supply to different economic activities. Therefore, if a SAM can take into account more disaggregated level of factor income and its distribution across various social groups of households, it will be of intense use for understanding the causes of income inequality and poverty in the Indian economy. Moreover, if we can understand the sectorwise share of income received by various types of labour and their relationship with various types of households, it will help government to prioritize interventions for poverty alleviation in India. However, the available SAMs for India as listed in Table 1 are not able to explain this phenomenon.

In this regard, the only evidence is obtained from the draft report on “Policy Dilemmas in India: The impact of Agricultural Prices on Rural and Urban Poverty” prepared by Polaski et al. (2008). In this study, the authors have constructed a Micro SAM for India consisting of 115 sectors, 49 primary factors and 352 households. The factors of production are classified into 49 groups according to their social group (SC/ST/OBC), their education level and their sex (male/female). But the base year of this SAM is 1998–1999 which is too old as compared to current structure of the Indian economy.

Given the backdrop of above-mentioned SAM constructed for India, we have decided to construct a latest SAM for India which will take into account detailed structure of value-added income by various sources of labour. As the latest available IO table for India is 2007–2008, we have constructed the proposed SAM for the year 2007–2008. The following section describes in detail about the method construction and data sources.

Steps involved in constructing value-added disaggregated SAM for the year 2007–2008

The latest official input–output (IO) table of Indian economy is available for the year 2007–2008 which consists of 130 sectors (CSO 2012). Further, this IO table has been used by Pradhan et al. (2013) to construct a SAM for India for the year 2007–2008 which consists of 78 sectors. Therefore, we have considered the 130-sector IO table, the 2007–2008 SAM, as the basis of our proposed disaggregated SAM for India for the year 2007–2008. Although the basis of our proposed SAM is the available SAM of the Indian economy for the year 2007–2008, they are significantly different in terms of the value-added disaggregation and the household classification. Our proposed SAM is an extension of the existing SAM of the year 2007–2008. As in compiling any SAM, the construction of our proposed disaggregated SAM involves a number of steps and these are explained as follows.

  • Step 1 Identify types of factor input and relevant data for every selected sector of SAM.

  • Step 2 Identify households’ classes and their source of income from various primary factors.

  • Step 3 Itemwise consumption expenditure of various households groups.

  • Step 4 Estimate sources of income other than factor income for various categories of Indian households.

  • Step 5 Balancing the database and consistency checks.

The detailed description of these steps is given in the subsequent paragraphs of this paper.

Step 1: identify types of factor input and relevant data for every selected sector of SAM

For the proposed disaggregated SAM, we have disaggregated only the labour input into 48 various types of labour. Here we have used region, social class, education and gender as four indicators to classify the labour input. The detail about these indicators is given in Table 2.

Table 2 Description of indicators to classify labour input

Once we classify the types of labour according to their location, social status, level of education and gender, our next task is to obtain data on payment for these types of labour by different sectors. In this case, we have estimated the distribution of labour payment across the SAM sectors by using the unit-level households survey data on employment and unemployment situation in India. The National Sample Survey Organization (NSSO) of India conducts detailed household survey in every 5 years separately for consumption expenditure and employment unemployment situation in India. The 68th round survey data for the year 2011–2012 are latest available quinquennial survey data for both consumption expenditure and employment–unemployment situation in India. Prior to the 68th round survey, immediate latest quinquennial survey data are available for the year 2009–2010 (66th round) and for the year 2004–2005 (61st round). Therefore, it was challenging for us to select a database to fulfil the data need for this proposed SAM. It is also worth noting that the Indian economy has experienced 9% GDP growth during the periods from 2005–2006 to 2007–2008. Although the real GDP growth dipped down at 6.7% level in the year 2008–2009, it has reached more than 8% level and continued at that level till 2011–2012 (CSO 2012). Now with the faster economic growth between 2004–2005 and 2011–2012, structure of the economy has also changed and hence the structure of employment. Table 3 presents the compound annual growth rate (CAGR) of employment between the year 2004–2005 and 2011–2012. Table 3 shows that the employment in agriculture sector has fallen during this period at a rate of 1.55%, whereas it has increased significantly at a rate of 13% in the construction sector. Apart from that, other sectors also experience positive growth in employment between the year 2004–2005 and 2011–2012.

Table 3 Sector-specific employment growth between 2004–2005 and 2011–2012 (CAGR)

Now since the base year of our proposed SAM is 2007–2008, the NSSO 61st round data will not capture the structural change happened during the golden periods of Indian economy during post-2004–2005 periods. Again as there was severe drought in India in the year 2009–2010, the 66th round quinquennial survey has been updated with 68th round survey for the year 2011–2012. Therefore, to capture the structural change in Indian economy during post-2004–2005 period, we have selected NSSO 68th round data to estimate required data for our proposed SAM of India for the year 2007–2008.

The NSSO employment survey classifies industries at the 5-digit level as described in National Industrial Classification (NIC) guideline. The households demographic and social profile data of the same survey have been first organized to classify the types of labour according to the description as mentioned in Table 3. Further, we have aggregated the industries according to their map of concordance with the sectors of our proposed SAM. In this context, the map of concordance between the sectors of our proposed SAM and the NIC 5-digit classification of industries is given in “Appendix 1”.

Step 2: identify households’ classes and their relationship with various primary factors

To make our value-added disaggregated SAM useful for poverty analysis, understanding structure of consumption expenditure across various social classes of households is important. Therefore, we have classified households into 80 different classes. In Table 4, we have listed various indicators which have been used to classify households.

Table 4 List of indicators to classify households

After classifying households according to the above-mentioned categories of classes, we have estimated sources of income of these households from different types of labour and capital. It is also important to note that household’s typewise data on capital stocks are not readily available for Indian economy. Therefore, we have used the income of self-employed and own account category of households as proxy of the capital income. Now to estimate the capital income this way, we have cross-tabulated the NSSO 68th round employment–unemployment survey data between households categories (using demographic profile) and types of labour (using status of work profile of the households). Again to obtain the income of the households from different types of labour, we have prepared another cross-table between the household categories and the types of labour we have defined for our study purpose.

Step 3: itemwise consumption expenditure of various households groups

To complete the construction of consumption block of this proposed SAM, we have used National sample survey (NSS) 68th round data on households’ consumption expenditure. But the descriptions of commodities in these databases are different than the sectors of our proposed SAM. So to overcome this problem also, we have used the map of concordance between the NSSO items and SAM sectors as given by Pradhan et al. (2013).

Step 4 and Step 5: estimating households income from other sources and balancing the SAM

In the above-mentioned steps, we have estimated the required data for our proposed SAM especially for those accounts which make this SAM significantly different from others. Now in this step, we have completed the construction by obtaining data on households’ income other than factor income. This includes transfer income from government, interest receive from public bonds and remittances from the abroad. To obtain these data corresponding to the different category of households, we have first taken the aggregate data from 2007 to 2008 SAM and then distributed it among the different class of households according to their share in aggregate consumption expenditure as obtained in the previous step.

Therefore, by following above-mentioned steps we have constructed a value-added disaggregated SAM for India for the year 2007–2008 which consists of 171 rows and column. The entire SAM is given as the supporting document along with this paper (Additional file 1: Appendix S1). But construction of proposed accounts for this SAM with NSSO data does not ensure that this SAM is balanced. This implies the row total is not equal to corresponding column total, because the NSSO data are obtained through primary sample survey and are available in market price, whereas data presented in IO table are based on factor price. Therefore, to make this SAM balanced we have followed following two steps. First, estimate the distribution patterns for households factor income from different types of labour and itemwise consumption expenditure and sector wise labour payment using the NSSO data. Secondly, a pro-rata adjustment method has been applied to distribute the aggregated data of existing 2007–2008 SAM according the distribution pattern. Thus, we have adjusted the NSSO data with the aggregate-level data on household income, consumption expenditure and sectorwise labour payment as obtained from the existing SAM of the year 2007–2008 to complete the construction procedure.

Validation of the value-added disaggregated SAM

The construction of value-added disaggregated SAM, as described above sections, requires data from different secondary sources. For example, the National Accounts Statistics (NAS) provides aggregated data for most of the macroeconomics indicators such as gross domestic product (GDP), private final consumption expenditure, households’ savings, government savings, corporate savings, savings of the public non-departmental enterprises and net factor income from abroad. The IO table provides data on inter-industry transaction as factor price for the year 2007–2008. The available SAM of the year 2007–2008 also gives data on macroeconomic indicators in factor price. Finally the detailed consumption expenditure data are obtained from NSSO unit-level survey data of the year 2011–2012. Since we have adjusted the NSSO data to fit into our proposed SAM framework, it is also necessary to check whether the SAM loses its viability to represent the macroeconomic situation of the Indian economy for the year 2007–2008. Therefore, to validate the SAM we have extracted the data for key macroeconomic indicators and compared it with the officially available data for macroeconomic indicators of Indian economy for the year 2007–2008. The detail is given in Table 5.

Table 5 Key macroeconomic aggregates from SAM and NAS data (trillion rupees)

As we observe from the above table that for most of the macroeconomic indicators the data obtained from our disaggregated SAM do not differ much with the official data available for Indian economy for the year 2007–2008. Again the maximum error is observed by 6% for net domestic transfer account. Apart from that, the exports and households savings data obtained from SAM recorded 5 and 3% error, respectively. However, the overall presentation of the above tables ensures that the disaggregated SAM is not only a balanced data set, but it represents the current macroeconomic situation of the economy for the year of estimation.

In addition to the above-mentioned macroeconomic indicators, we have also taken into account per capita consumption expenditure to check consistency in terms of their economic status of various social groups of households taken into consideration in this SAM. Table 6 describes the monthly per capita consumption expenditure of various categories of households. Here we have compared the monthly per capita consumption expenditure (MPCE) data as can be obtained from SAM with the available NSSO data of the year 2011–2012. Table 6 shows that the MPCE obtained from SAM differs from that of obtained from NSSO data, but the relative positions of each households group are same in both the cases. This is because of the adjustment of the data and the time period taken into consideration to collect the original data through primary survey. The NSSO uses consumption expenditure of the households for the month of survey as the reference for their estimation, whereas the SAM data take into account annualized value of the private final consumption expenditure. Furthermore, the NSSO data are based on current price, whereas the SAM data are on factor costs. So due to difference in method and year of estimation, one can get difference in terms of absolute numbers, but the relative position of the households as obtained from the NSSO must not vary irrespective of data sources one is using for macroeconomic policy analysis. Therefore, we have adjusted the survey data in such a way that social and economic status of the Indian households does not change.

Table 6 Monthly per capita consumption expenditure obtained from SAM and NSSO 68th round survey (Rs.)

Application of value-added disaggregated SAM

The purpose of constructing or extending a SAM will not be fulfilled unless we demonstrate its applicability in policy making for that country of concern. Therefore, in this section we have described some analyses using the SAM database. First, we have estimated the contribution of various social groups of Indian households on net domestic product (NDP) of India of the year 2007–2008. Further we have compared their contribution to NDP with their contribution in total population of India in the year 2007–2008. The purpose of this estimate is to understand the average productivity of various social groups of households in India. If it is found that a particular category of households contributes smaller share in NDP but occupies larger share of population, it can be argued that this households group is lower productive than other group of households. Secondly, we have estimated types of labour supply by the various social groups of household to understand the causes of lower contribution in NNP. Thirdly, we have estimated the Gini coefficients for rural and urban households separately to understand the level of income inequality within each social group of households. Finally, we have applied SAM multiplier model to analyse the impact of agriculture sectors growth on rural income inequality.

Contribution of households in India’s national income

Figure 1 describes the contribution of various social groups of households in India’s NDP of the year 2007–2008. If we add the percentage contribution to NDP by the various social groups of households (including rural and urban), we find almost 87% of NDP is contributed by the households and rest is contributed by the government, private corporate and public non-departmental enterprises. In addition to estimating contribution to NDP by various households groups, we have also estimated the composition of various social groups in India’s total population and it is superimposed in Fig. 1. Figure 1 shows that urban area in India is residence of almost 30% of her total population and contributing almost 43% of her NDP. By contrast, the 70% population lives in rural area and contributing only 44% of total NNP which is almost 30% lower than their population contribution. This scenario is quite obvious as rural economy is dependent on agriculture sector which is lowest contributor to GDP in India as compared to manufacturing and service sector. Again, more than half of the Indian population is based on agriculture sector as their primary source of livelihood. Yet again, it is interesting to observe that the gap between percentage contribution towards population and NDP is lower for the households belong to other social group in rural. According to Fig. 1, the other social group of households occupies only 17% of total population and contributes almost 13% India’s NDP in the year 2007–2008, whereas the households belong to OBC social group occupy one-third of the India’s population and contribute only 21% of India’s NDP. Thus, it can be argued from this figure that the average productivities of the rural population that belong to the social groups schedule tribe (ST), schedule caste (SC) and other backward class (OBC) are lower than the rural population belong of other social group. On the other hand, in urban area the percentage share in population is lower than their contribution to NDP across every social group. Hence, it can also be argued that the urban households irrespective of their social belonging are more productive than their rural counterpart.

Fig. 1

Households categorywise share in population and net domestic product

Further, in Table 7 we have shown the distribution of worker across their skill. The number of workers is estimated using NSSO 68th round survey and their categorization according the level of skill is based on their level of education (see Table 7). Table 7 shows that in rural area 48% of total workers supplied by the ST category households are unskilled. In case of SC category households, the share of unskilled worker is 43% and it is 36% for the OBC category households. The share of unskilled worker in total worker for other social group households is lowest (i.e. 23%) in rural areas. However, in urban areas the share of unskilled worker in each category of social group is lower as compared to their rural counterpart. Therefore, it can be argued from the above discussion that the source of income of the socially marginalized group in India is largely dominated by the income from unskilled worker, and hence, the average productivity is lower for these categories of households in India as shown in Fig. 1.

Table 7 Distribution of employed population (PS + SS) across various types of skills.

Analysis of income inequality across various social groups

Again our value-added disaggregated SAM categorized households according to the expenditure deciles class. Therefore, the households income data presented in our value-added disaggregated SAM can be used to estimate the level of inequality across rural and urban households. In this study, we have estimated Gini coefficient as a measure of inequality and the results are shown in Fig. 2.

Fig. 2

Gini coefficients across various social groups of households

Figure 2 plots the Gini coefficients for different social groups of households across rural and urban area in India for the year 2007–2008. Higher value of Gini coefficients explains higher level of income inequality. Here, the highest level of inequality is observed for the urban households (0.44) than their rural (0.29) counterpart. In rural area, highest level of income inequality is observed among the other category households (0.63) which is 2.5 times higher than the OBC category households (0.24), 3 times higher than SC category households and 4 times than ST category of households. Therefore, the income inequality among the ST households (0.16) category is lowest in rural area. By contrast, the same is higher for the same social group (ST category) of households in the urban area, i.e. 0.34. The lowest income inequality in urban area is observed for the SC category households (0.22). Further, it is interesting to note that the Gini coefficients for urban area are higher for all social groups of households that the rural areas except the households belongs to other social group. The Gini coefficient for other category of households is 0.54 for urban area as compared to 0.63 in rural areas. Now if we relate these income inequality estimates to their corresponding per capita income as shown in Table 8, we see a direct relationship between the two indicators for each group of households. Therefore, it can be argued that with the increase in per capita income the level of income inequality increases irrespective of region and social status of the households. This issue corroborates the rising part of the Kuznets curve. But at what point this level of inequality will starts falling is a crucial research question. Using the SAM multiplier model, one can further simulate with various policy options to understand their impact on income inequality in India. Below we have described an illustrative example of SAM multiplier analysis on the impact of growth in various crop and food processing sectors on rural income and inequality.

Table 8 Impact of agriculture-related activities on rural income and inequality

Impact of agricultural growth in rural income and inequality: SAM multiplier analysis

In this section, we have presented the SAM multiplier analysis to see the impact of agricultural growth on rural and income and inequality. The following table describes the cropwise impact on rural income for different types of households. The impact on income is obtained from the SAM multiplier matrix corresponding to the interaction between rows of the households and column of the economic activities. Thus, the value 0.085 for ST category households corresponding to paddy crops explains the impact on income of that particular group of households due to growth in paddy crop sector by one unit. Similarly we can explain the rural income values for each household category corresponding to various agricultural activities. Using this multiplier value, we have estimated the Gini coefficient to observe how the increase in income will be distributed across various decile classes of households within each households class. Further we have also estimated the overall impact on rural income and rural income inequality. Again though we have ten various crop sectors in our SAM, we have selected few major crops for illustration purpose.

As it is observed from Table 8, if there is an increase in output of paddy crop sector by one unit, income of rural ST households will increase by 0.085 unit which is highest ever the increase as compared to other listed sectors in this table. Moreover, this increase in income will be distributed more equally among the ST households as compared to growth in income due to growth in other crop sectors. Similar fact is also observed for the SC households. However, the OBC category and other types households gain income more due to growth in livestock sector and this income growth is more equally distributed (lowest GINI coefficient, i.e. 0.17 and 0.37, respectively, for OBS and others) among the households of those classes than the growth in other sectors. In totality, the rural income inequality will be lower, i.e. 0.17, due to growth in paddy crops than the growth in other activities reacted to agriculture and listed in this above table.

It is also interesting to observe that the growth in pulses crops will lead to overall growth in income by 0.807 unit which is lower than other farm-related activities but higher than the growth in food processing industry, i.e. 0.723. Yet again the growth in income due to growth in pulses crops leads to rise in rural income inequality (i.e. 0.38) than the growth in paddy (0.17), livestock (0.23) and even vegetables crop (0.32). Moreover, growth in pulses crop leads to rise in income inequality among various social groups of households.

The SAM multiplier is a static observation for the year 2007 and is highly influenced by the social and economic structure of the Indian economy. Cereals being a principal crop in Indian agriculture (especially paddy) and paddy being the major staple food for most of the India, a large share of agricultural land is employed for this crop cultivation. As a result, the growth in paddy crop leads less income inequality among the rural households in India. Further, the pulses crops are dominated in arid and dry agro-climatic zones in India, and due to such in equal distribution of pulses growers, the income effects also lead to rise in income inequality in Indian economy. Therefore, unless the area under pulses increases in other parts of the country the inequality in rural income cannot be reduced. In this context, Government of India has integrated pulses crop under national food security mission to promote pulses crops in India and rice fallow region of eastern India is also the prime focus for pulses production. Once achieved, we may expect reduction in income inequality within the rural area. It is also to be noted that the Indian economy has been moving through the structural transformation process since 1991, but to reduce the income inequality, a structural transformation is required within the agriculture sector with more focus towards livestock and pulses crops.


The SAM has been applied by various developed and developing countries since its inception in the academic literatures by the pioneer work by Stone (1962). India is not exception to this and it has been adopted as a policy planning tool for its government during decades of 1980s and 1990s. Despite this, limited effort has been made to extend the existing structure of a SAM with more detailed accounts so that more micro-level analyses can be done with the focus of inclusive growth. In this context, our attempt to construct a value-added disaggregated SAM for India fills the gap in macroeconomic database. Again the brief description about application of this SAM gives an overview of the social structure of the Indian economy and their contribution to the national income. Another important application of this SAM is that we have shown in this study by estimating Gini coefficient for each social group of households. It is also important to note here that the database presented in this SAM is robust as it is consistent with the official macroeconomic data of the Indian economy. Moreover, the analysis on income inequality, using this SAM data, does not diverge from theoretical foundation of Kuznets curve as well as the reality of the Indian economy.

Furthermore, this value-added disaggregated SAM can be applied as balanced data source for a computable general equilibrium (CGE) model especially to analyse various policy options on social inclusion and inclusive growth. The analysis can also be done to understand the impact on types of labour demand (skilled and unskilled) due to various policies. The demand of such types of analyses is crucial for the developing country such as India to guide her policy makers with suitable policy options to achieve sustainable goal. However, addressing this issue requires further research using this database.

However, constructing such a disaggregated level of SAM database is a tedious job and requires readily available data. Although we have made a challenging attempt to adjust the data obtained from different sources into a single matrix form, this task can be made more easily if Government of India can publish its IO table regularly corresponding to each NSSO rounds survey. Hence, the novelty of the SAM lies on its level of disaggregation and further research is needed to make the data available and their applicability in policy making. This issue is also important for the developing country as they are planning to move towards sustainable development goals.

Last but not the least, the SAM multiplier analysis can be extended by including more crops or economic economics to identify key economic activities to reduce rural income inequality as more than 70% population in India are living in rural areas. However, this analysis can be made more robust if we can have a SAM of the latest year, say, for the year 2014–2015. A latest available SAM will help us to observe the recent structural transformation and its impact on rural income inequality in India.
