Chapter 07. What to Make in India?
Manufacturing or Services?

7.1 INTRODUCTION
Echoing the Sage of Singapore, Prime Minister Narendra Modi has elevated the revival of Indian manufacturing to a key policy objective of the new government, identifying this sector as the engine of long-run growth. “Make in India” is now a flagship initiative not to mention a catchy campaign. But the question arises “What should India make?” Early development thinking, exemplified most famously (though not exclusively) in the two-sector model of Lewis (1954) was fixated on the idea of sectoral transformation: moving resources from the agricultural/traditional sector to the manufacturing/ non-traditional sector. There was never any doubt about the hierarchy (the latter was unquestionably superior) and hence no doubt about the desirability of the structural transformation.

Although development thinking over the last two decades has moved away from discussions about sectoral transformation and towards a more explicit growth perspective, the importance of structural transformation is starting to be rehabilitated – but without abandoning the growth perspective. Rodrik (2013 and 2014) provides the clearest exposition of this marriage of the two perspectives.

7.2 DESIRABLE FEATURES OF SECTORS THAT CAN SERVE AS ENGINES OF STRUCTURAL TRANSFORMATION

India is taken up as a case study for addressing this question due to the poor performance of manufacturing in India and the relatively strong performance of services – which in some ways mirrors the performance of many Sub-Saharan African countries (Ghani and O’Connell, 2014).

Lee Kuan Yew was clearly on to something when he challenged the Indian model of development. Historically, there have been three modes of escape from under-development: geology, geography, and “jeans” (code for low-skilled manufacturing). In recent years West Asia, Botswana and Chile, and further back in time Australia and Canada, exploited their natural resources endowed by geology to improve their standards of living. Some of the island successes (Barbados, Mauritius, and others in the Caribbean) have exploited their geography by developing tourism to achieve high rates of growth. In the early stages of their success, East Asian countries (China, Thailand, Indonesia, Malaysia etc) relied on relatively low-skilled manufacturing, typically textiles and clothing, to motor economic growth. Later on they diversified into more sophisticated manufacturing but “jeans” offered the vehicle for prosperity early on. No country has escaped from underdevelopment using relatively skill-intensive activities as the launching pad for sustained growth as India seems to be attempting.

Put differently, India seems to have defied its “natural” comparative advantage, which probably lay in the “jeans” mode of escape because of its abundant unskilled and low-skilled labor. Instead, it found or created—thanks to historical policy choices and technological accidents—such advantage in relatively skilled activities such as information technologies and business process outsourcing (Kochhar et. al., 2007). The Indian experience, still a work-in-progress, raises the question of whether structural transformation necessarily requires manufacturing to be the engine of growth. But before we compare manufacturing with alternative sectors in terms of their potential for structural transformation, it is worth elaborating on the desirable attributes of such sectors.

In fact, building upon the Rodrik (2013) framework, it is argued that there are five attributes that allow a sector to serve as an engine of structural transformation and thereby lead an economy to rapid, sustained and inclusive growth:

1. High level of productivity: As described above, economic development is about moving from low productivity to high productivity activities.

2. Unconditional Convergence (i.e. faster productivity growth in lower productivity areas):
This too has been discussed earlier. Recall that convergence ensures that the relevant sector acts as an “escalator” which automatically leads to higher levels of sectoral and economy-wide productivity. In fact one can distinguish between two types of unconditional convergence:
A. Domestic convergence: In large countries such as India, China, Brazil, and Indonesia, one would ideally like to see convergence within a country.
That is, productivity growth should be faster in richer than poorer parts.
Otherwise severe within-country regional inequality may arise.
B. International convergence: whereby less-productive economic units (firms, sectors or entire economies) in all countries catch-up with units at the international frontier (i.e. those in the most productive countries).
3. Expansion: To ensure that the dynamic productivity gains from convergence spread through the economy, it is necessary that the sector experiencing convergence absorbs resources.
Convergence accompanied by contraction will fail to ensure economy-wide benefits, because the country’s resources that are outside the sector in question will not experience higher, convergent productivity growth. Convergence, in the case of the industrial sector, should be accompanied by natural industrialisation and not premature deindustrialisation, if it is to lead to truly inclusive growth.
4. Alignment with comparative advantage: To ensure that expansion occurs and the benefits of fast-growing sectors are widely shared across the labor force, there should be a match between the skill requirements of the expanding sector and the skill endowment of the country. For example, in a labour abundant country such as India, the converging sector should be a relatively low-skilled activity so that more individuals can benefit from convergence.
5. Tradability: Historically, countries that had growth spurts enjoyed rapid growth in exports, typically manufacturing exports (Johnson, Ostry and Subramanian (2010)). Rapid growth has seldom been based on the domestic market. Part of the reason for this might be that trade serves as a mechanism for technology transfer and learning, which may have spillovers on related industries (Hausmann, Hwang, and Rodrik (2007)). Perhaps a more important part is that trade and exports in particular provide a source of unconstrained demand for the expanding sector. This is particularly important for a country of India’s size because of the possibility that its expansion can run up against the limited political and economic ability of trading countries to absorb Indian exports and/or to turn the terms of trade against itself.
The two sectors—manufacturing and services (including services disaggregated by subsector)— are now evaluated, in succession, along these five dimensions in the Indian context.3

7.3 THE MANUFACTURING SCORECARD
7.3.1 Productivity Level
Table 7.1 compares productivity (measured simply as value added per worker) levels in the various Indian sectors – including manufacturing – for two time periods: 1984 and 2010. Several features stand out. First, in India it is highly misleading to speak generally of manufacturing because of the clear difference between unregistered manufacturing – which is a very low productivity activity – and registered manufacturing – which is an order of magnitude (7.2 times) more productive.
It is registered manufacturing, not manufacturing in general, which has the potential for structural transformation.
Second, the level of productivity in registered manufacturing is not only high relative to unregistered manufacturing, it is high compared to most other sectors of the economy and it is even high in an absolute sense, at US$ 7800 at market exchange rates and nearly three times as much at PPP exchange rates. If the entire Indian economy were employed in registered manufacturing, India would be as rich as say Korea.
Third, these differentials between registered manufacturing and the rest of the economy were alreadly prevalent (if not to the same extent) in 1984 – fast productivity growth over the period (about 5 percent per year) has only exacerbated the differences.
Thus, on the first criterion of high levels of productivity, registered manufacturing scores spectacularly well.

7.3.2 Domestic convergence
Figure 7.1 provides evidence that registered manufacturing is characterised by unconditional domestic convergence. Here the unit of observation is the State-Industry level, but almost identical results are derived when looking at more aggregated levels (across major states in India) and less aggregated levels (across factories). Broadly a regression coefficient on log of initial productivity of about (-) 2.5 percent suggests that a state that is twice as rich as another has an average growth rate of productivity that is 2.5 percent slower – a considerable amount given that the average growth rate of productivity over the period 1984-2010 was about 4.4 percent.

7.3.3 International Convergence
With respect to registered manufacturing, it seems that states and firms within India are converging to the Indian frontier but that could mean little unless they are also converging to the international manufacturing frontier. Are they? Rodrik (2013) shows that there is unconditional convergence across countries and sectors in manufacturing. But India is a negative outlier in the relationship in two senses: first, on average, manufacturing sectors in India exhibit labour productivity growth that is 14 percent less than the average country’s manufacturing sector. Second, Indian industries converge at a much slower rate than average (0.005 percent)—almost not at all. In contrast, China is a positive outlier, posting faster labour productivity growth than average and converging faster to the global frontier. Registered manufacturing in India has thus not been a strong performer.
7.3.4 Expansion or Pre-mature non-Industrialisation?
It is a stylised fact that the process of development includes stages of industrialisation followed by deindustrialisation: a country first experiences a rising share of resources – especially labour – devoted to the industrial sector, after which the services sector becomes more important, so that the share
of employment in the industrial sector declines from
its peak. In recent years, however, “deindustrialisation”
seems to be taking place
prematurely. That is, poor countries seem to be
reaching their peak levels of industrialisation at
lower levels of industrialisation and income
(Rodrik, 2014; Amirapu and Subramanian, 2015).
What about India? The phenomenon of deindustrialisation
is particularly salient for India for
three reasons. Looming ahead is the demographic
bulge, which will disgorge a million youth every
month into the economy in search of employment
opportunities. Rising labour costs in China create
opportunities for low-skilled countries such as
India as replacement destinations for investment
that is leaving China. And a new government that
has assumed power offers the prospect of
refashioning India in the image of Gujarat—one of
the few manufacturing successes.
But the sobering fact is that India seems to be deindustrialising
too. In fact, to call the Indian
phenomenon de-industrialisation is to dignify the
Indian experience, which is more aptly referred to
as premature non-industrialisation because India
never industrialised sufficiently in the first place.
To make the point first consider Figure 7.2, which
plots the share of manufacturing in total
employment over time for South Korea, a poster
child for manufacturing-led growth. South Korea’s
GDP per capita in 2005 PPP dollars is also shown
alongside the series for several years. The figure
displays the typical shape: share of employment in
manufacturing starts very low at around 5 percent
and rises over time to almost 30 percent before
starting to decline after a fairly high level of GDP
has been reached.
In contrast, Figure 7.3 illustrates the Indian
experience. The Figure shows India’s share of
registered manufacturing in total output and
employment over time (on the same axes as the
graph for Korea). The general trend is constant
with a downward trend over the last few years for
which data are available. In other words, the
pronounced inverted U shape that characterises
the cross-section and Korea is notably absent in
India.
But what has been the counterpart development
among Indian states? Tables 7.2A and 7.2B show
the year in which the share of registered
manufacturing peaked (in first value added and
then employment terms), the peak share of
registered manufacturing (in value added or
employment), and the per capita GDP associated
with peak registered manufacturing levels.
From the tables, a few points are striking. Gujarat
has been the only state in which registered
manufacturing as a share of GDP surpassed 20
percent and came anywhere close to levels
achieved by the major manufacturing successes in
East Asia. Even in Maharashtra and Tamil Nadu,
manufacturing at its peak accounted for only about
18-19 percent of state GDP. The peak shares in
employment terms are even less significant: no
major Indian state has achieved more than 6.2
percent of employment from registered
manufacturing in the last 30 years, and many major
states peaked at less than half that. Even in Gujarat,
employment in registered manufacturing has only
been about 5 percent of total employment, while
annual growth in registered manufacturing
employment has been 1.8 percent between 1984
and 2010 (slower than the growth rate of total
employment over the period: 2.4 percent).
Second, in nearly all states (with the exception of
Himachal Pradesh and Gujarat), registered
manufacturing as a share of value added is now
declining and, for most states, has been doing so
for a long time. The peak share of manufacturing
in output for many states was reached in the 1990s
(Andhra Pradesh and Tamil Nadu) or even in the
1980s (Maharashtra). Interestingly, peak
employment shares seem to be following a slightly
different story, with less marked declines
observable for most states. Nevertheless, most
states have not been experiencing secular growth
in employment shares over time (the only
exceptions are Himachal Pradesh, Tamil Nadu,
Haryana and – possibly – Karnataka). Many of
the states that do exhibit peak years in 2010 (such
as Andhra Pradesh, Rajasthan and Orissa) seem
to have employment shares that have been mostly
flat, reflecting neither relative growth nor decline.
Third, and this is perhaps the most sobering of
facts, manufacturing has even been declining in the
poorer states: states that never effectively
industrialised (West Bengal and Bihar) have started
de-industrialising.
Some comparisons are illuminating. Take India’s
largest state Uttar Pradesh. It reached its peak
share of manufacturing in output at 10 percent of
GDP in 1996 at a per capita state domestic
product of about $1200 (measured in 2005
purchasing power parity dollars). A country like
Indonesia attained a manufacturing peak share
of 29 percent at a per capita GDP of $5800.
Brazil attained its peak share of 31 percent at a
per capita GDP of $7100. So, Uttar Pradesh’s
maximum level of industrialization was about onethird
that in Brazil and Indonesia; and the decline
began at 15-20 percent of the income levels of
these countries.
Thus far, we have shown that, for all but a few states, Indian manufacturing is certainly not growing and is probably shrinking. One possible consequence of manufacturing failing to satisfy requirements 2b and 3 is that, in contrast to China, there is no evidence of convergence between states in India in overall per capita GDP. For Chinese provinces, the poorer the initial level of per capita GDP, the faster the subsequent growth, so that poorer provinces start catching up with richer ones. In India, there is no convergence, because poorer states are not likely to grow faster than richer ones on average (Amirapu and Subramanian 2015).
Regional disparities have thus persisted within India.
Had manufacturing attracted resources while exhibiting domestic convergence in productivity, the sector would have expanded in poorer states increasing overall levels of income in these states and contributing to a narrowing of the income distribution across India. Instead it seems that manufacturing has failed to be such an escalatorof progress.
Several explanations are possible for why manufacturing has not been this escalator in India.
They fall under four broad categories: distortions in labour markets; distortions in capital markets; distortions in land markets; and inappropriate specialisation away from India’s natural comparative advantage and toward skill intensive activities. Amirapu and Subramanian (2015) provides some evidence in support of the last explanation.
7.3.5 Alignment with Comparative
Advantage
As argued earlier, in order for a sector to offer transformational possibilities, it must not only be characterised by high levels and growth rates of productivity, it must also absorb resources from the rest of the economy. But in order to do so, the sector’s use of inputs must be aligned with the country’s comparative advantage. That will allow the abundant factor of production (usually unskilled labour) to benefit from productivity growth and convergence, and in so doing make growth not only rapid and sustainable but also inclusive. In other words, the dynamic sector must at least initially be relatively unskilled labour intensive. Is this true of India manufacturing? Kochhar et. al. (2006) found that Indian manufacturing was
unusually skill labour intensive. Another simple
metric for assessing the alignment of dynamism with
comparative advantage is the relative skill intensity
of manufacturing relative to other sectors. Table
7.3 presents some numbers. From the 2004/5
NSSO Employment and Unemployment Survey,
the share of employees with at least primary and
secondary education for major sectors (and
subsectors) of the Indian economy is computed.
It turns out that registered manufacturing is a sector
that is relatively skilled labor intensive. As table
7.3 shows, the share of workers with at least
secondary education is substantially higher in
registered manufacturing than in agriculture, mining
or unregistered manufacturing and also greater than
in several of the service subsectors. In some ways,
this should not be surprising. High labour
productivity in this sector (Table 7.1) is at least in
part a consequence of higher skills in the work
force. What it does suggest, however, is that
registered manufacturing does not really satisfy
requirement number four. The skill intensity of the
sector is not quite aligned with India’s comparative
advantage.
7.4 THE SERVICES SCORECARD
The scorecard analysis can be repeated for the
services sector in India. But before that is done, it
is important to recognise that services in the
aggregate is not a useful category of analysis
because it is an amalgam of different and disparate
species of economic activity, from government
services and construction that are non-tradable to
finance and business services that largely are
tradable; from certain activities that are labour
intensive and others such as telecommunications
that are highly capital and skill labor intensive. Any
meaningful analysis of services must distinguish
between different service subsectors—although
the degree of disaggregation will of course be
determined by data availability.
We work with the six different subsectors shown
in Table 7.4 and repeat the analysis undertaken
above for registered manufacturing.
7.4.1 Productivity Level
Table 7.4 provides comparative data on the level
of productivity for these service subsectors as well
as for manufacturing (both registered and
unregistered). The first point to note is the
astounding variation within services, reinforcing the
case for disaggregation. In 1984 for example, the
level of productivity in the real estate and business
services sectors was 25 times as much as in public
administration (essentially government) and close
to 20 times as much as in retail. The productivity
levels in two—financial services and business
services—out of six service subsectors exceed that
of registered manufacturing.
7.4.2 Domestic convergence
The issue of whether there was unconditional
convergence within India for service subsectors
over the last 3 decades is now examined. Notably,
unconditional domestic convergence is found in
nearly all the service subsectors, and across many
time horizons (not reported here). In fact, the speed
of domestic convergence for most service
subsectors is found to be similar to that in registered
manufacturing (about 2 percent) and, in some
cases, substantially higher. For example, real estate
and business services seem to converge at double
the rate at which registered manufacturing
converges.
7.4.3 International Convergence
Rodrik (2013) provides evidence using UNIDO
data that industries in the (organized) manufacturing
sector consistently exhibit global convergence in
labour productivities, although Indian
manufacturing industries converge to the global
frontier much more slowly than the average, if at
all. What about the service subsectors?
Using data on sectoral productivities from the
World Bank’s World Development Indicators
(WDIs), Ghani and O’Connell (2014) argue that
services in the aggregate have also exhibited
convergence to a similar or even greater degree
than manufacturing – at least for recent time periods
(approximately 1990 to 2005). This is an
interesting finding, but for this analysis in particular
services should be disaggregated as we might well
expect convergence behaviour to vary by subsector
due to significant differences in sectoral
characteristics such as tradability.
Table 7.5 reports international convergence results
by service subsectors over the period 1990 to
2005 using data from the Groningen Growth and
Development Centre (GGDC). Although the set
of countries in the analysis is severely limited due
to data availability,7 the results are still interesting.
We see that some service subsectors (Finance,
Insurance, and Real Estate; Community, Social and
Personal Services; and Construction) do seem to
exhibit strong international convergence, while
others (Trade, Hotels and Restaurants; Transport,
Storage and Communication) do not. Surprisingly,
the set of sectors exhibiting convergence seems to
include even some apparently non-tradable
sectors, such as construction.
The conclusion thus far seems to be that many–
but not all – service subsectors satisfy the
requirements of high productivity growth, domestic
convergence, and international convergence.
7.4.4 Expansion of Services?
Evidence that the share of output and employment
from manufacturing in India had hardly changed in
30 years has already been presented. In the Tables
below analogous evidence for services in India –
both in aggregate and for particular service
subsectors is presented.
In contrast to registered manufacturing – the share
of output from aggregate services rose dramatically
over the last 30 years, from about 35 percent to
more than 50 percent of GDP. The share of
aggregate services in employment, in contrast,
increased in a far more modest fashion (see Table
7.6). But there is nevertheless a distinct contrast
with registered manufacturing. Aggregate services
employment grew faster than that in registered
manufacturing and a number of service
subsectors—transport, real estate and
construction—registered substantially faster
employment growth. In other words, services are
becoming an ever more important source of wealth,
and while they have not delivered rapid employment
growth, a number of service sub-sectors have
generated more rapid employment growth than
manufacturing.
7.4.5 Alignment with comparative advantage?
We argued above that, in a low-skilled labour
abundant country like India, a sector must make
use of this dominant resource in order to offer the
greatest possibilities for expansion and structural
transformation. We also saw that registered
manufacturing was a fairly skill-intensive sector
with high average educational attainment.
The same table also shows that services in
aggregate are no less skill-intensive: on average,
78 percent of workers in the service sector have
at least a primary education (77 percent in
registered manufacturing), and 48 percent have at
least a secondary education (43 percent in
registered manufacturing). Furthermore, a large
number of service subsectors – including 1)
Banking and Insurance, 2) Real Estate and
Business Services, 3) Public Administration, 4)
Education, and 5) Health and Social Services –
have significantly higher educational attainment
(90 percent or more of workers have at least
primary education) than registered manufacturing.
What this implies is that most service subsectors
(precisely the high productivity, high growth
subsectors, for the most part), have a limited
capacity to make use of India’s most abundant
resource, unskilled labor. This may explain why
the share of employment from services has risen
so modestly, even while the share of output from
services has grown so spectacularly.
7.5 SUMMARY SCORECARD AND
CONCLUSIONS
Table 7.6 below provides a summary scorecard
comparing registered manufacturing and selected
service subsectors. Before proceeding further, let
us make clear a few important points. First, we
compare service sectors with only the registered
(i.e.: formal) manufacturing sector, because
unregistered manufacturing is one of the lowest
productivity sectors in the Indian economy– apart
from agriculture – and so offers little promise for
transformation. So, when there is talk on the
transformational potential of manufacturing in India
the focus must be exclusively on registered
manufacturing.
Second, another contribution of this chapter is to
offer an alternative way of thinking about
transformational sectors beyond the traditional
distinction based on manufacturing versus services.
We have taken the position of comparing sectors
based on their easily observable underlying
properties. To be sure, there may be less tangible
differences between manufacturing and services
that are left out in our analysis.
For example, our present analysis does not
consider the extent to which certain sectors (such
as registered manufacturing) may be more likely
to induce learning spillovers to other sectors of
the economy, which may be important. Other
missing dimensions include the political one: Dani
Rodrik has suggested that manufacturing may play
an indirect role in the political development of young
nations by providing a forum in which citizens learn
to practice compromise in a democratic context
through the struggle between labour and capital
“on the manufacturing shop floor” (Rodrik,
2013b). Though our analysis leaves out such
channels, we believe they are second-order in
comparison with the 5 desirable features laid out
earlier.
Proceeding to the comparison, there does not seem
to be anything distinctive or superior about
registered manufacturing when compared with
certain other service subsectors. Like
manufacturing, several of the service subsectors
also exhibit high productivity and convergence –
both domestic and international. However, they
also share the shortcoming that these sectors are
highly skill intensive in their resource requirements,
which is out of kilter with the skill profile of the
Indian labor force. Their potential to generate
widely shared or inclusive growth is thus likely to
be limited – and indeed seems to have been so
given the lack of expansion observed earlier (and
which is recorded in the scorecard).
One sector that markedly stands out from the
others in the table below is construction: it appears
to exhibit both types of convergence, does not
require high education levels and has grown
significantly in its resource use over the last three
decades. However, the sector is not tradable and
in any case is low productivity, so that moving labor
resources to the sector does not considerably
improve overall welfare.
So, in some ways, the choice for India is not
manufacturing versus services but comparative
advantage deifying (unskilled-intensive) sectors
versus comparative advantage defying (skillintensive)
sector development. This is both a
positive and a policy question.
While India’s skill-intensive pattern of development
has no doubt been costly, there has been a
significant upside. Myron Weiner, among others,
has drawn attention to the disappointing post-
Independence performance of the Indian state in
delivering education, reflected in very slow
improvements in literacy rates, especially amongst
women. While the supply of educational services
by the state was inadequate, the puzzle arose as
to why there was not greater demand for education
and hence greater pressure on the state to meet
this demand.
One answer to this puzzle is that the private returns
to literacy and basic education must have been
low. There is now evidence that the increasing
opportunities that are spurring economic growth
also contribute to raising these returns, leading to
a greater demand for educational services—public
and private—and hence improvements in
educational outcomes (Munshi and Rosenzweig,
2003). This has put pressure on the supply of
education. The government’s failures to provide
good schools are well-known, but growth has
changed the picture dramatically, largely because
it has increased the returns from education—and
hence the demand for it.
Evidence is provided by the work of economists
Kartik Muralidharan and Michael Kremer who
show that private schools are mushrooming in rural
India (many prominently advertising “English
Medium”) because of teacher absenteeism in
public schools. One also hears of companies
creating training centers to build skills in the cities
(such as the Infosys institute in Mysore) because
institutions of higher education are notoriously
inadequate. This endogenous increase in human
capital could be one of the offsetting benefits of
the comparative advantage-defying, skill-intensive
growth model.
The policy question is the following. Insofar as
the government retains influence over shaping
the pattern of development, should it try to
rehabilitate unskilled manufacturing or should
it accept that that is difficult to achieve, and
create the groundwork for sustaining the skill
intensive pattern of growth? Attempting the
former would be a history-defying achievement
because there are not many examples of significant
reversals of de-industrialisation. A lot would have
to change in India—from building the infrastructure
and logistics/connectivity that supports unskillintensive
manufacturing to reforming the panoply
of laws and regulations—or perhaps addressing
corruption in the manner of their enforcement—
that may discourage hiring unskilled labor and
achieving scale in the formal sector.
Sustaining a skill-intensive pattern on the other hand
would require a greater focus on education (and
skills development) so that the pattern of
development that has been evolving over time does
not run into shortages. The cost of this skill
intensive model is that one or two generations of
those who are currently unskilled will be left behind
without the opportunities to advance. But
emphasising skills will at least ensure that future
generations can take advantage of lost
opportunities.
In some ways, the choice confronting India is really
about how to make it a Lewisian economy that
has unlimited supplies of labor. India can either
create the conditions to ensure that its existing
unlimited supplies of unskilled labor are utilisable.
Or, it can make sure that the currently inelastic
supply of skilled labor is made more elastic. Both
are major challenges.
What the analysis suggests is that while Make in
India, which has occupied all the prominence, is
an important goal, the Prime Minister’s other goal
of “Skilling India” is no less important and perhaps
deserves as much attention. Make in India, if
successful, would make India a Lewisian economy
in relation to unskilled labor. But “Skilling India”
has the potential to make India a Lewisian
economy with respect to more skilled labor. The
future trajectory of Indian economic development
could depend on both.
