INDIAN INCOME INEQUALITY, 1922-2014: FROM BRITISH RAJ TO BILLIONAIRE RAJ ?

Abstract

We combine household surveys and national accounts, as well as recently released tax data in a systematic way to track the dynamics of Indian income inequality from 1922 to 2014. According to our benchmark estimates, the share of national income accruing to the top 1% income earners is now at its highest level since the creation of the Indian Income tax in 1922. The top 1% of earners captured less than 21% of total income in the late 1930s, before dropping to 6% in the early 1980s and rising to 22% today. Over the 1951-1980 period, the bottom 50% group captured 28% of total growth and incomes of this group grew faster than the average, while the top 0.1% incomes decreased. Over the 1980-2014 period, the situation was reversed; the top 0.1% of earners captured a higher share of total growth than the bottom 50% (12% vs. 11%), while the top 1% received a higher share of total growth than the middle 40% (29% vs. 23%). These findings suggest that much can be done to promote more inclusive growth in India. Our results also appear to be robust to a range of alternative assumptions seeking to address data limitations. Most importantly, we stress the need for more democratic transparency on income and wealth statistics to avoid another "black decade" similar to the 2000s, during which India entered the digital age but stopped publishing tax statistics. Such data sources are key to track the long run evolution of inequality and to allow an informed democratic debate on inequality.

This version: September 7, 2017 Abstract. We combine household surveys and national accounts, as well as recently released tax data in a systematic way to track the dynamics of Indian income inequality from 1922 to 2014. According to our benchmark estimates, the share of national income accruing to the top 1% income earners is now at its highest level since the creation of the Indian Income tax in 1922. The top 1% of earners captured less than 21% of total income in the late 1930s, before dropping to 6% in the early 1980s and rising to 22% today. Over the 1951-1980 period, the bottom 50% group captured 28% of total growth and incomes of this group grew faster than the average, while the top 0.1% incomes decreased. Over the 1980-2014 period, the situation was reversed; the top 0.1% of earners captured a higher share of total growth than the bottom 50% (12% vs. 11%), while the top 1% received a higher share of total growth than the middle 40% (29% vs. 23%). These findings suggest that much can be done to promote more inclusive growth in India. Our results also appear to be robust to a range of alternative assumptions seeking to address data limitations. Most importantly, we stress the need for more democratic transparency on income and wealth statistics to avoid another "black decade" similar to the 2000s, during which India entered the digital age but stopped publishing tax statistics. Such data sources are key to track the long run evolution of inequality and to allow an informed democratic debate on inequality. 1 World Inequality Lab, Paris School of Economics 2 IDDRI - Sciences Po 3 Ecole des Hautes Etudes en Sciences Sociales Corresponding author : lucas.chancel@psemail.eu We thank Nitin Bharti for extremely valuable research assistance.

India introduced an individual income tax with the Income Tax Act of 1922, under the British colonial administration. From this date, up to the turn of the 20th century, the Indian Income Tax Department produced income tax tabulations, making it possible to track the long-run evolution of top incomes in a systematic manner. Using this data, Banerjee and Piketty (2005) showed that the share of fiscal income accruing to the top 1% earners shrank substantially from the mid-1950s to the mid-1980s, from about 13% of fiscal income, to less than 5% in the early 1980s. The trend was reversed in the mid-1980s, when pro-business, market deregulation policies were implemented. The share of fiscal held of the top 1% doubled from approximately 5% to 10% in 2000.

According to National Accounts estimates, post-2000 income growth has been substantially higher than in the previous decades. Average annual real income growth was below 2% in the 1960 and 1970s, it reached 2.5% in the 1980s and 2% in the 1990s1. Since 2000s it is of 4.4% on average since 2000 (Figure 1). Little is known however on the distributional impacts of economic policies in India after 2000 in part because the Income Tax Department stopped publishing income tax statistics in 2000, and also because self-reported survey data does not provide adequate information concerning the top of the distribution (fiscal data is not perfect either, but it delivers higher and more plausible income levels for the top). In 2016, the Income Tax Department released tax tabulations for recent years (2011- 12, 2012-13 and 2013-14), making it possible to revise and update previously published top income estimates and better inform public debates on growth and income inequality. We find that the bottom 50% group grew at a substantially lower rate than average growth (Figure 1a) since the 1980s. Middle 40% grew at a slower rate than the average (Figure 1b). On the contrary, top 10% and top 1% grew substantially faster than the average since 1980 (Figure 1c).

The first objective of this paper is to mobilize this newly released set of tax data in order to track the evolution of income inequality from 1922 to 2014. The second objective is to go beyond top income shares and produce estimates of income dynamics throughout the entire distribution using concepts that are consistent with National Accounts (following, as much as possible, the Distributional National Accounts Methodology, see Alvaredo et al., 2016).

To do so, we combine in a systematic manner household survey, fiscal and national accounts data. Such an exercise is fraught with methodological and conceptual difficulties given the lack of consistent historical income inequality data in India. Indeed, the tax data available only covers the very top of the distribution of Indian earners (more than 6% of total population in 2014). In addition, the National Sample Survey Organization (NSSO) household surveys measure consumption rather than income. We repeatedly stress that there are strong limitations to available data sources, and that more democratic transparency on income and wealth statistics is highly needed in India. That said, we find that our key results are robust to a large set of alternative assumptions made to address data gaps. The present paper should be viewed as an exercise in transparency: we propose a method to combine the different available sources (in particular national accounts, tax and survey data) in the most possible transparent way, and we very much hope that new data sources will become available in the future so that more refined estimates can be constructed. All our computer codes are available on-line so that everybody can use them and contribute to improve the methods.

The rest of this paper is organized as follows. Section 1 discusses the Indian income inequality data gap of the past two decades, section 2 describes our

1 ENTERING THE DIGITAL AGE WITHOUT INEQUALITY DATA

1.1 Economic policy shifts since the 1980s

Over the past thirty years, the Indian economy went through profound evolutions. In the late seventies, India was recognized as a highly regulated economy with socialist planning. From the 1980s onwards, a large set of liberalization and deregulation reforms were implemented. In this context, it is unfortunate that Indian authorities stopped in 2000 publishing income tax tabulations, which represent a key source of data to track consistently the evolution of top incomes.

Under Prime Minister Jawaharlal Nehru (in power from 1947 to 1964), India was a statist, centrally directed and regulated economy. Transport, agriculture and construction sectors were owned and administered by the Central Government, commodity prices were regulated and the country had important trade barriers. Nehru's followers, including Indira Gandhi's (1966-77 and 1980- 1984) prolonged these policies and implemented a highly progressive tax system. In the early 1970s, the top marginal income tax rate reached record high levels (up to 97.5%).

From the mid 1980s onwards, liberalization and trade openness became recurrent themes among Indian policymakers. The Seventh Plan (1985-1990), led by Rajiv Gandhi (1984-1989), promoted the relaxation of market regulation, with increased external borrowing and increased imports. The tax system was also gradually transformed, with top marginal income tax rates falling to 50% in the mid-1980s. In the late 1980s, when India faced a balance of payment crisis, it called for International Monetary Fund assistance. Financial support was conditioned to structural reforms which pushed forward the deregulation and liberalization agenda.

What came to be known as the first set of economic reforms (1991-2000) placed the promotion of the private sector at the heart of economic policies, via denationalizations, disinvestment of the public sector, deregulation (dereservation and delicencing of public companies and industries)2. These reforms were implemented both by the Congress government of N. Rao (1991-1996) and its successors, including the conservative Janata Party government of A. Vajpayee (1998-2004). The reforms were prolonged after 2000, under the 10th and

subsequent five-year plans. These plans ended government fixation of petrol, sugar or fertilizer prices and led to further privatizations, in the agricultural sector in particular.

The impacts of these reforms in terms of growth has been praised by public authorities. Real per adult national income growth, which has more sense from the point of view of individual incomes than commonly used GDP3, significantly increased after the reforms. It was 0.7% in the 1970s, 2.5% in the 1980s, 2.0% in the 1990s and 4.4% since 2000 (Figure 1). However, little is known on the distributional characteristics of post-2000 growth.

1.2 The income inequality data gap

Public debate over liberalization policies largely focused on their macroeconomic impacts (Ramaswami, Kotwal, Wadhwa, 2011) and on the impacts on poverty, with a substantial reduction in poverty rates4 (World Bank, 2017; Deaton & Dreze, 2002; Deaton & Kozel, 2005). How the Indian economy fared in terms of inequality has been arguably less discussed. This can partly be explained by a lack of consistent data on the distribution of incomes or wealth for the recent period. Some evidence suggesting a rise in income inequality in India after the turn of the century can however be found in NSSO surveys and other sources available in openly-available sources. Figure 2 presents the share of total consumption attributable to the top 20% of consumers, available online from the World Bank and United Nations WIDER World Income Inequality Database (UN-WIDER WIID). The data shows a decrease in top quintile consumption share from the fifties to the seventies from around 43% to 40% and an increase thereafter (in line with Banerjee and Piketty findings) to close to 44%. There are important irregularities with the data, but the overall "U-shape" trend seems relatively consistent5.

3 Net national income is equal to GDP minus depreciation of fixed capital plus net foreign incomes. 4 The share of Indians under the $1.9 poverty line went from 45.9% in 1993 to 21.2% in 2011 (PovcalNet, 2017) 5 As discussed below, income surveys sources exist for 2005 and later years; in particular data from the National Council for Applied Economic Research (NCAER) and from the Inter University Consortium for Applied Political and Social Sciences Research (ICPSR. These data sources however do not enable comparison before and after 2000.

and World Bank India Database (based upon NSSO surveys)

The shortcomings of household survey data in monitoring the evolution of

inequality are well known; because of underreporting and undersampling issues, surveys fail to properly capture inequality dynamics at the top of the distribution (Atkinson and Piketty, 2007, 2010). What is more, NSSO surveys only focus on consumption rather than income and the distributional dynamics of these two concepts can differ notably. In addition, the relatively limited magnitude of the changes observed in NSSO data calls for care in the interpretation of such results. Consumption data available through surveys constitutes part of the evidence, but are not sufficient to inform debates on Indian inequality.

Other data sources, such as Forbes' Indian Rich lists, suggest an important increase in the wealth of the richest Indians after 2000 (see

Figure 3). The wealth of the richest Indians reported in Forbes' India Rich List, amounted to less than 2% of National income in the 1990sn, but increased substantially throughout the 2000s, reaching 10% in 2015 and with a peak of 27% before the 2008-9 financial crisis. Such data suggests a rise in wealth inequality levels throughout the post-2000 period, but does not enable a consistent analysis of income inequality over the long run. This is confirmed by simple simulations using a fixed normalized wealth distribution and taking into account rising average nominal wealth over the period (unfortunately Indian wealth data is very limited so it is difficult to go further).

The recent release of income tax tabulations by the Income Tax Department

for the post 2011 period does, however, allow for a more consistent analysis of the dynamics of income in India since the turn of the century.

2 DATA SOURCES AND METHODOLOGY

We present the data used to produce series on the evolution of income for the entire distribution from 1951 to 2014 (period covered by both household surveys and tax data, as well as national accounts) and for the evolution of incomes of the top 1% share and above from 1922 to 2014 (period covered by tax data and national accounts only, with no survey data prior to 1951).

2.1 Description of the different data sources

2.1.1 Tax data

The Indian Income Tax Department released tax tabulations for the fiscal years 1922-1923 to 1998-1999, and interrupted the publication in 2000. After several public calls for more democratic transparency over Indian inequality data6, the ITA released tax tabulation for years 2011-12 to 2013-14. All these tabulations report the number of taxpayers and the gross and returned income for a large number of

income brackets7. Gross income corresponds to pre-tax income before certain deductions are applied to compute returned income8. Tax units are defined as individuals or Hindu Undivided Families (HUF, family clusters allowed to file their income jointly). The number of HUF represented roughly 20 % of tax returns in the interwar period, 5% in 1990 and less than 2.5% in 2011.9

The exact reason why Indian tax administration stopped publishing data in 2000 remains unknown. One potential explanation for this is the change in the sampling method employed in the late 1990s, with a resulting loss in the precision of estimates. Indeed, official tax tabulations were based on the entire population until the early 1990s - or based on stratified samples with sampling rates close to 100 percent for top incomes as is the case in most OECD countries, but seem to be based on uniform samples of all tax returns after this period and up to 2000 (Banerjee and Piketty, 2005). The latter method led to less precise results10. Another potential explanation for the halt in tax reporting could just be the lack of interest in income statistics and inequality (which given the rise in top income shares observed from mid 1980s to 2000 seems rather surprising).

Interestingly enough, the number income tax payers in India has increased substantially over the past decades. Less than 0.5% of the population filing tax returns up to the 1950s, between 0.2 and 1% over the period between 1960 to 1990, before a substantial increase thereafter; from 1% to close to 3% in the late 1990s and more than 6% in the latest period (Figure 4)11. This increase over twenty years is impressive, yet comparatively, the current figure is similar to the levels observed in France and in the USA in the late 1910s, and much lower than the levels observed in the interwar period (about 10-15%) and in the decades following World War 2 (50% or more) in these two countries (Piketty, 2001; Piketty and Saez, 2003). With revenues from income tax equivalent to approximately 2% of GDP, India receives more revenue than China (1%), but significantly less than other emerging countries

7 According to the Income Tax Department, a number of tax payers paid their taxes but did not file returns in fiscal years 2011- 2013. In order to take into account these individuals, we assumed that they fell in the lower income tax brackets. We tested alternative assumptions: i) assuming they are fully representative of other income filers and ii) assuming they all fall in the lowest taxable bracket. These alternative assumptions have very limited impact on our final results. Minor corrections were also done to raw tax data and mainly pertain to the clubbing of brackets in some years as the average income was incompatible with the bracket they were categorized. In such rare cases, we club erroneous brackets in the lower bracket. Year 1997 was removed altogether, as data is erroneous. 8 Deductions are defined at chapter VI of the Income Tax Act. They include premiums of annuity plans, equity fund investments, medical or health insurance, certain forms of donations, etc. Focusing on gross income is more accurate in terms of pre-tax income and is also less impacted by changes in the definitions of deductions. Income losses (such as business income losses) have to be adjusted while computing Gross Total Income as per Income Tax law. Note that imputed rent for owner occupied dwellings were included in Income tax computations before 1986 and removed afterwards. More precisely, post 1986 tax data excludes imputed rent for first residence, but not for secondary residences. 9 One should note that the Indian income tax data is entirely based upon individual income. This corresponds to equal-split income (ie. income shared among spouses) only if we assume that all tax-payers are either single or married to other tax-payers falling in the same bracket, which strictly speaking cannot be true. This implies that our estimates tend to over-estimate inequality as compared to the equal-split benchmark and to under-estimate inequality as compared to the individualistic benchmark. If and when we access to micro-level Indian tax data, we will be able to refine this analysis and compute separate equal-split and individualistic series. 10 For year 1997, see Appendix 2. 11 This figure includes estimated tax payers who did not file returns post-2011. They represent approximately 30% of the number of tax payers, according to the Income Tax Department.

2.1.2 NSSO consumption data

The NSSO, led by the Ministry of Statistics and Program Implementation started an all-India consumer household expenditure survey (AIHS) after its independence in 1947. The first round of the AIHS was carried out in 1951 and surveys were then conducted on an annual basis. The size of rounds varies since the quinquennial AIHS has a larger sampling of about 120 000 households and five times less for smaller other rounds. The reach of the quinquennial survey is extensive in terms of consumption items (ranging from daily used food, clothing to durable goods and services such as construction, education and healthcare). NSSO surveys however do not measure individual or household incomes12, in part because agricultural and business incomes are judged to be volatile and assumed to be much less reliably measured than consumption.

12 The Employment Unemployment Surveys report wages for the working-age population, but other sources of income are not covered.

Since the first survey rounds, NSSO produced 30 days reference period estimates. This period is known as the Universal Reference Period. Post-1990, concerns were raised about the sensitivity of the reference period on the estimates and NSSO started publishing alternative reference periods (7 days and 365 days). As Deaton and Kozel (2005) note, shorter recall periods tend to lead to higher consumption estimates. However, experiments carried out with different reference periods by the NSSO working group concerned concluded that there is no clear superiority of a period over another. We thus use the Universal Reference Period. This choice is also motivated by the fact that the 30 days period is the only one that is consistent throughout the entire period of analysis (1951-2014).

For recent years (1983 to 2011) we use quinquennial rounds 38 (1983), 43 (1987-88), 50 (1993-94), 55 (1999-2000), 61(2004-05), 66 (2009-10). Micro data at the household level was obtained from the NSSO. For earlier rounds (rounds 3 to 32), for which we could not access micro data files, we use the Poverty and Growth in India Database of the World Bank (Ozler et al., 1996) which provides rural and urban per capita consumption tabulations for a dozen quantile groups for years 1951 to 1978. All rounds and corresponding years used are summarized in Appendix 3, along with the summary statistics of each round. We describe in section 2.2.2 the procedure used to infer the full distribution of income from these surveys and how we interpolate missing years.

2.1.3 National Accounts data

From 1950 to the present day, we use GDP data from WID.world, based on National Accounts Statistics (NAS) from 1971 to 2013, on World Bank (after 2013) and on Maddison (2007) from 1950 to 197013. WID.world then performs its own computations to infer Net Foreign Income and Consumption of Fixed Capital (Blanchet and Chancel, 2016). Before 1950, we use historical National Income growth rates from Sivasubramonian (2000).

A well know puzzle in Indian statistics (Deaton and Kozel, 2005; CSO, 2008) pertains to the difference in survey consumption growth rates and national accounts growth rates, particularly during the recent period. Figure 5 shows the total growth rate of Net National Income and Household Final Consumption Expenditure from NAS and personal consumption from NSSO, from 1983 to 2011. According to NAS, national income grew at 475% and household consumption grew at slightly more than 300%, while NSSO data indicates that household consumption grew at 200%.

13 In the 1990s we observe noticeable differences between real GDP growth estimates obtained from UN SNA and those reported by the World Bank (see Appendix 1).

12

Figure 5 - Cumulated growth rates according to NAS and NSSO

Source: Authors' computations using national accounts and NSSO data. Several reasons have been put forward to explain this gap, including (i) population coverage (it is different between NSSO and NAS, since Non Profit Institutions Serving Households and homeless individuals are not covered by NSSO surveys); (ii) valuation and integration of certain types of services in survey questionnaires (it was argued that the treatment of cooked meals served by employers to employees leads to underestimation of the total value of services consumed by households in the NSSO surveys (CSO, 2008) while other services such as financial intermediation that are particularly important among top earners, are not included in survey estimates (Sundaram and Tendulkar, 2005); (iii) imputed rents (while the NAS incorporates imputed rents, NSSO surveys do not14); (iv) consistency of National Accounts estimates (Kulshreshtha and Kar, 2005) ; (v) under-reporting and under-sampling of top incomes in survey data (Banerjee and Piketty, 2005). We should stress from the outset that we do not pretend to solve this complex issue. The divergence probably involves several, if not all of the factors above cited.

14 When correcting for imputed rents the Central Statistical Organization (2008) finds a large and growing share of total consumption remains unexplained.

Total real growth rate in India, 1983-2011

Household consumption (NSSO)

What we seek here is to better estimate the fraction of the difference that can be explained by the absence of top earners in survey data. We do not think that this factor alone can explain the entire gap, as it has sometime been suggested (Lakner and Milanovic, 2015).

2.1.4 IHDS income and consumption survey

The Inter University Consortium for Applied Political and Social Sciences Research (ICPSR), based at the University of Michigan, provides access to the India Human Development Survey (IHDS), conducted in 2005 and 2011-12 among more than 40 000 households from rural and urban areas. The survey provides information at the household level on both income and consumption. Consumption related questions were designed so as to match the NSSO questionnaire, using similar item categories and similar referencing periods. The definition of income in the IHDS survey includes all sources of income: labour income (wages and pensions), capital income (rents, interests, dividends, capital gains) as well as mixed (or business) incomes15. Government benefits, reported in the survey, are excluded from the analysis for consistency with tax tabulations; our focus is pre-tax income.

The IHDS is one of the very few surveys estimating both consumption and income in India. This is particularly useful as it enables a tentative reconstruction of NSSO unobserved income levels, using IHDS information. We describe this methodology in section 2.2.2. IHDS micro data is also openly available via the ICPSR website, which makes it particularly convenient16.

2.1.5 UN statistics population data

We define the theoretical population of tax payers as the total number of

adult individuals in India. We use adult population data from UN Population Prospects (2015) from 1950 to today. UN Population prospects provide 5-year age range annual population tables, based on national census and their own estimation procedures. The adult population is defined as the number of individuals over age 20. Before 1950, we use total population estimates from Sivasubramonian (2000) and reconstruct the adult population using total population growth rates given by the same author.

15 Imputed rents are not included in IHDS survey. They are not taken into account in NSSO data, nor in tax data after 1986. 16 We were not able to access the micro files of the National Council for Applied Economic Research's National Income and Expenditure Survey, done in 2004-5 and 2010-11.

2.2 Methodology

2.2.1 Estimation of top fiscal incomes

Following Banerjee and Piketty (2005), we first reconstruct top income thresholds and levels, using generalized Pareto interpolation techniques. The main methodological difference with Banerjee and Piketty lies in the use of generalized Pareto interpolation techniques (Blanchet, Fournier and Piketty, 2017) rather than standard Pareto distributions. Generalized Pareto interpolation17 allows for the recovery of the distribution based on tax tabulations without the need for parametric approximations. This method has demonstrated its ability to produce very precise results and also has the advantage of generating smooth estimates of the distribution, i.e. generating a differentiable quantile function and a continuous density, while other methods introduce kinks around the thresholds used as inputs for the tabulation.

The generalized Pareto interpolation procedure generates 127 generalized percentiles, namely p0p1, p1p2, ..., p99p100, corresponding to 100 fractiles of the distribution. The top fractile is split into 10 deciles (p99.0 p99.1, p99.1 p99.2,..., p99.9p100), its top decile itself split in ten deciles (p99.90 p99.91, p99.91 p99.92, ..., p99.99 p100), the tenth decile again split in ten deciles (p99.990p99.991, p99.991 p99.992, ..., p99.999p100). The top generalized percentile thus corresponds to the top 0.001% of the population. As shown in Figure 4, tax data in India is only reliable above the p94 threshold for the recent period and above the p99.9 threshold when we go backwards in time.

2.2.2 Estimation of bottom survey incomes

One of the main difficulties of our exercise is related to the fact that NSSO does not include questions on individual and/or household income. Our strategy consists of using observed income-consumption profiles in IHDS data to reconstruct income profiles from NSSO consumption data. We first estimate income and consumption levels for each generalized percentile of the distribution of income and consumption given by IHDS data. For each survey and each percentile of the distribution, we construct observed income-consumption ratios α1p=yp/cp, with yp and cp respectively with a mean income and consumption within quantile p. We call this strategy A1. To obtain a theoretical income-consumption profile over percentiles, we take average of years 2005 and 2011-12. In practice, the two profiles differ only marginally. We then construct two alternative ratios, α2p and α0p, referred to as strategies A2 and A0 respectively. In strategy A2, we assume 17 Available online at www.wid.world/gpinter

that α2p= 1 for α1p≤1 and α2p=α1p otherwise. This second strategy is equal to assuming no negative savings rates among the poor. In strategy A0, we define α0p=(α1p+α2p)/2 for α1p≤1. This strategy assumes that there can be negative savings rates, remittances or household transfers, but that the true αp value lies between strategy A1 and strategy A2. Income consumption ratios for the different strategies are presented in Appendix 4. We find that these different strategies have no effect on the trends we observe and a limited impact on top share estimates, as we show in section 3.4.

The choice of these different strategies indeed impacts on the estimated share of total savings in the economy. In strategy A1 total savings are close to 0, which seems too low compared to the current rate of savings in India (about 30%). This figure is close to 5% in strategy A0 and approximately 10% in strategy A2. These values are more or less constant throughout the entire period covered whereas in National accounts they move from about 10% in the 1960s to 30% today. However, using strategy A0 and factoring in top incomes in the analysis allows us to find an aggregate savings rate of the same order of magnitude as those observed today (see Appendix 5).

2.2.3 Interpolating survey and tax data for missing years.

Our objective is to produce yearly estimate for the full distribution from

1951 to 2014. Given that survey or tax data is not available for all years, it is necessary to interpolate tax and/or survey data for a certain number of years. In order to do so, we interpolate missing years using a constant growth rate between known intervals t and t+N18.

As described in sections 2.1.2 and 2.1.4, we have two available sources for the estimation of survey income for the years 2005 and 20010-11, NSSO and IHDS. However, the trends observed in the surveys are somehow divergent. The ratio of reconstructed NSSO total income to total personal income from national accounts decreases, while the ratio of IHDS total income to total personal income from national accounts is stable. The choice of one or the other source of data has implications on our final inequality statistics: using IHDS means for the estimation of the bottom of the distribution (strategy B1) yields a lower rise in top income shares than when using the NSSO survey (strategy B2). However, using NSSO mechanically accentuates the rise in top shares over the period and the strategy B1

18 In practice, for each average income at percentile p of the survey (or tax) distribution, we define ypt+1=ypt×g where g=(ypt+N/ypt)1/N, with g the growth rate, ypt+1 the average income at percentile p and year t+1.
