CHAPTER TWO
STRUCTURE AND PERFORMANCE OF ELECTRONICS INDUSTRY
2.1 Introduction
One of the most important approaches to study industrial economics is the structure
conduct-performance approach. The structure-conduct-performance paradigm
recognizes that the overall performance of a firm is influenced by the structure and
conduct variables. It hypothesizes that the degree of market concentration is
inversely related to the degree of competition and positively related to profit. In this
model the main causality moves from industry structure (concentration ratio)
variable to firm conduct variables (strategy) and then performance (profit) variable.
The Structure conduct performance can be understood with the help of perfect
competition and monopoly. Perfect competition is based on existence of large
number of firms, equal size, free entry and exit. Here profit is at normal level,
because its equilibrium price is determined at price equals marginal cost and average
cost. However, under monopoly the structure is high barrier to entry, and profit is
super-normal because price is above marginal cost and marginal cost is equal to
marginal revenue. In other words, as the market moves from large number of firms to
a few firms in the industry, the profitability will rise from normal level towards the
super-normal level. However, these are two extreme cases; present study does not
fall under either of these markets. In other words it falls somewhere in between. It is
oligopoly or monopolistic market condition that generally prevails in the market.
To study performance generally Price-cost margin is used; the capital turnover,
employment, technical progressiveness etc., are some of other performance variables.
The structure of an industry covers factors like, seller concentration, buyer
concentration, product differentiation and entry barriers. The concentration indices
are grouped into absolute and relative concentration measures. The absolute measure
is the concentration ratio; it is measured by a given number of large firms share in
industry's size. The other method is Herfindahl index; it is obtained by squaring and
summing the share of industry size accounted for by every firm producing for the
industry. The relative concentration is measured through Lorenz curve. The generally
used structure variables are concentration ratio and the Herfindahl index. The Buyer
concentration is the ratio of movement of intermediate products from each seller
41
industry to each of its purchasing industries (using input-output statistics) (Guth et
al., 1977). The Product differentiation is said to prevail when the buyers are not able
to identify products as perfect substitutes. Many of the study's used advertisement
intensity as the proxy for product differentiation. Barriers to entry are obstacle for
new firms to enter in market for sales and production. It may be in the form of legal
obstacles, buyer loyalty, absolute cost advantages, economies of scale etc. The
conduct of firms covers the price-setting behaviour and the behaviour of rivals. The
commonly-used conduct variables are Research and Development, product
differentiation (advertisement), capital intensity, age of the firm, export intensity,
capital import intensity etc.
The Structure conduct performance model was initiated by S. Mason of Harvard in
1939 and elaborated by numerous scholars in the field of industrial organization
(Scherer and Ross, 1990; Sarah, 2003)1• Mason's study was focused on behaviour of
firms; latter it was shifted to industrial behaviour. Some of these concepts were
already found during 1925-40. Bain's has contributed to carrying forward of
scientific analysis and introduction of a proper shape. His seminal paper (1951) was
based on an analysis of the performance of US firms in 42 industries in the latter half
of the 1930; it found abnormal profits in relatively more concentrated industries than
those of relatively un-concentrated industries. This has helped to form the structure
conduct and performance paradigm. His articles 'Barriers to new competition' (1956)
and 'Industrial organisation' (1959) has strengthened structure conduct performance
paradigm. He emphasized that concentration is an important determinant of market
power and profitability.
During the 1960s, the structure conduct performance was modified and improved by
Mann (1966) and Wilson and Commonor (1967). Their results support Bain's
hypothesis. They modified and tested it by incorporating various variables of market
structure and conduct (Joseph, 1997). However, Demsetz (1973 and 1974) of
Chicago school approach has presented alternative explanation for abnormal
performance presented by Bain (1951). He stated that the abnormal result was due to

42
efficiency of firms, not the presence of collusive behaviour and pricing.2 Another
study by Brozen ( 1970, 1971) argued that Bain' s analysis was static and data may
have depicted diseq~ilibrium situa.tion. His analysis found that the level of abnormal
profit declined over the period; he therefore emphasised his disequilibrium argument.
Esposito and Esposito (1971) improved the model by incorporating import and
export variables. Porter (1979) also contributed by incorporating some of strategic
variables. Later studies, notably Bothwell, Cooley and Hall's (1984), have
introduced risk adjustment variables to the rates of profit of firms in different
industries.
Criticism
The structure-conduct-performance approach is a short-run static one. With
particular structure firms are seeking to maximize profit, subject to a constraint of
limiting entry into the industry. Caves (1967) argued that there is a causation
relation, i.e. market structure determines the behaviour of firms, and behaviour
determines the performance of firms. However, the performance of firms may be
determined by outside the influence of participating firms. The omission and mis
specification of variables may lead to mis-interpretation of result.
Demsets (1973 and 1974) argues that the abnormal profits may be the result of the
higher level of efficiency of firms, not the collusive behaviour or pricing. Brozen
(1970, 1971) argued that Bain's analysis was static and that Bain's data may have
reflected a disequilibrium situation. He found that the level of abnormal performance
declined over time.
Some of the variables of structure of industry, viz., advertisement, number of firms
etc., are determined by a series of historic accidents, which are not directly relevant
to current conduct and performance. The past conduct and performance of firms may
act as barriers for new firms. Maximization of profit and reinvesting in research and
development activity and advertisement heightens the existing barrier.
Contrary to the SCP hypothesis, the performance may influence structure of firm.
High profitability and expansion of sales would increases the size of firms. The
conduct variables may smoothen the entry of a firm into the industry influencing
2 He suggested testing the relation between structure and performance between firms of different sizes and their rates of return relative to industry average. He argued that larger size firms are more efficient than the smaller firms.
43
structure of industry. Departures from profit maximization may arise from
managerial strategies such as sales revenue maximization.
Technical factors determine the industrial structure, particularly the size of plant,
number of firms, the degree of concentration etc. The minimum efficient scale of
production (technical factors) plays a major role in moulding the structure of the
industry. Some of the variables are elements of structure, of conduct and of
performance; they may cause simultaneous equation problem, i.e. Advertisement.
The SCP model was initially developed in the United States, where the private sector
dominates the market. The same model may not be applicable in developing
countries or in mixed economies, where industrial activities are determined and
planned by the government. Government also determines foreign direct investment,
foreign participation, industrial licensing that moulds the structure of industry. India
consists of large-scale public sectors, whose objective is employment generation
rather than profit maximization. So, performance of firms is not completely
determined by market. Therefore, profit level may stabilize or decline at high level of
concentration through fear of government intervention.
The objective of this chapter is to study performance (price-cost margin) and
determinants of performance. To study this various conduct variables and structure
variable are used.
It has extended to study in detail structure (Herfindahl index) of electronics industry
both at aggregate and disaggregate level viz. consumer, industry, computer,
communication and component electronics. Further, attempt has been made to
analyse the relation between price-cost margin, wage share and excise duty.
The plan of the chapter is as follows. Section 2.2 opens with the relevant hypothesis
of factors affecting performance (price-cost margin) in electronics industry. This is
followed by specification of the model and source of data in Section 2.3. In Section
2.4, empirical findings of performance and structure have been analysed. Electronics
industry's concentration ratio (Herfindahl index) has been analysed both aggregate as
well as disaggregate level in Section 2.5.
It is followed by analysis of relation between price-cost margin, wage share and
excise duty in Section 2.6. Finally, the summary of findings is given in Section 2.7.

2.2 Factors Affecting Performance (price-cost margin): Hypotheses
It hypothesizes that the degree of market concentration is inversely related to the
degree of competition and positively related to profit. In this model the main
causality moves from industry structure (concentration ratio) variable to firm conduct
variables (strategy) and then performance (profit) variable. To study performance
(price-cost margin) and its relation with structure and conduct, various conduct
variables and structure v.ariable are used. Therefore the factors that are considered to
explain performance of firm are discussed below:
Firm Size
Larger firms with considerable resource bases (both financial and real) will have a
resource and scale advantage in investing in Information Technqlogy industry (Lal
K, 1995). The larger firms are more efficient than the smaller firms because the
former has comparative advantages over the latter in terms of technical factors,
managerial factors, marketing factors, financial factors etc. The Electronics industry
is capital intensive in nature and the larger firms are better suited than the smaller
firms. The larger the firm the more the division of labour in the production process,
which enhances the productivity and reduces the cost of production. Firms gain from
the arrangement of having different heterogeneous processes housed under the same
roof. It does away with certain vital costs like marketing costs, transportation costs,
heating and cooling costs and packaging costs etc. The potential management cadre
in the large size firms can handle the market problems more efficiently. The vast
majority of the companies in developing countries are small and they face problems
in raising capital. Many of the public sector companies are large in size. Large
companies appear to have relatively greater reliance on the capital market. Large
companies' access to sources of finance may have greater implication on structure
and competition of industry, and it enables to squeeze smaller companies particularly
in times of financial problems. The larger firm can handle sudden or unforeseen
demands or emergencies by maintaining equipment, stocks, cash, labour etc. The big
firms have power over suppliers, competitors and customers. It can force the
suppliers to charge lower input prices than those which are justified by the cost of
production. The larger firms can make use of their waste products economically
because of being available in greater quantities. It may use such products themselves
or make them available for others in some ancillary trade.
45
Singh and Whittington (1975) have classified separately twenty-one industry groups
and all firms together and found that the degree of dispersion of profitability
decreased with size of firm. Devine et al. (1985) found that the larger firms in
general experience less variability of profit rates than do smaller firms. Samuels
(1965) has examined a sample of 400 firms quoted on the London Stock Exchange
over the period 1950-51 to 1959-60 and found that larger firms grew at a
significantly faster rate than smaller firms, and that the degree of variability of
growth within a given size class did not differ between larger and smaller firms.
Hymer and Pashigian (1962) has examined the relationship between firm size and
growth rate for the 1000 largest US manufacturing firms over the period 1946-55,
and they found that the average growth rates did not differ for firms of different sizes
but that there was a systematic tendency for variance to decrease with size. On the
basis of the above explanation the Price-Cost margin of Indian electronics industry is
postulated to be positively related to the firm size.
Research and Development
Inventions are made because there is need for them. Radio, television and computer
are made with some purpose. Through invention, innovation and commercial
exploitation man controls the environment. Invention, innovation and imitation are
the successive stages in industrial research and development activity. Invention as
'an idea, a sketch or a model for a new or improved device, product, process or
system and an innovation in the economic sense is accomplished only with the first
commercial transaction involving the new product, process, system or device'
(Freeman, 1982). The cost associated with Innovation is much more than the cost
associated with the invention. Lloyd (1970) indicates that costs associated with
invention are only of the order of 10 per cent of the total costs of innovation and
invention. Invention and innovation are risky and important part of the industrial
activity. An invention provides an opportunity to gain more profit for those firms
which adopt it. But once the other firms use this innovation, it may become obsolete,
so many of the firms do not sell their invention. For those firms which do not
innovate, demand for those products may disappear; this may put pressure on the
firms to engage in research and development activity. Innovation has some character
of public goods; once it is introduced, it is difficult to prevent other firms from
46
getting access to it. So, the inventors are protected through patent laws, which give
certain rights over the use of their invention for a specified period.
The large firm favours research and development because of its economies of scale.
The firms often may become large because of research and development activity; in
other words, research and development investment and profits are positively
associated. Freeman (1982) concludes that R&D programmes are highly
concentrated in a relatively few firms. In the study, firms with over 5000 employees
accounted for 90 per cent of all industrial R&D expenditure in the USA and for
around 75 per cent in West Germany and the UK. In contrast, the vast majority
(around 95 per cent) of small firms (with less than 200 employees) do not have any
specialized research programme. Scherer (1965) finds some tendency for research
intensity to first rase and then fall with firm size. But Soete (1979), examining data
for the USA in the 1970s, found some tendency for R&D intensity to continue to"
increase with firm size even amongst the largest firms. Empirical study by Kamien et
al. (1982) over fifteen years have shown that, although there may sometimes be
certain advantages of size in exploiting the fruits of R&D, it is more efficiently done
in small or medium-size firms than the large ones. Blair (1972) has found some
evidence based on American lawsuits that some large firms have tried to withhold
inventions, because new inventions threaten the viability of existing products. This
evidence shows large laboratories tend to produce minor inventions. Profit generates
funds for R&D expenditure and R&D expenditure generates profit and provokes
market position (Lall, 1980; Manfield, 1969; Galbraith, 1972; Grabowski, 1968).
In this study R&D has been measured R&D expenditure over the sales. Adoption and
adaptation of the domestic technology is less expensive than the foreign technology.
This independent attitude boosts the confidence of domestic entrepreneurs. With the
help of domestic R & D firms can replace obsolete products with new products
according to the changing environment which ultimately helps to increase the profit.
Hence, holding other things constant it is postulated that higher the R & D
expenditure the more the Profit.
Technology Import
It is often discussed that developing countries import the technology from the
developed countries, resulting in a mismatch between the technological requirements
of the former and the available technology (Pack et al., 1969). Developed countries
47
are capital abundant and labour scarce; on the contrary developing countries are
labour abundant and capital scarce. Since, innovation of technology is capital
intensive, most of the invention and innovation takes place in developed countries.
To protect technology, they often resorted for Prohibitive tariff and patents. Gallini
(1984), Katz and Shapiro (1986), Kamien and Tauman (1986) and Muto (1990) have
studied technology licensing and its implication on the R & D of the potential
entrant. They emphasised that once the technological trade takes place then there
would be no difference among the firms. Some of other studies by Desai (1988),
Alam (1985) and Kabiraj (1990) have examined and found that the factors such as
small market size, low demand and payment constraints may result in trade of
second-hand know-how. As far as the technology leader and buyer are concerned,
they concluded that the reason for not selling advance technology to buyers is the
threat of the entry of technology buyers into their (technology leaders') existing
market network.
The liberalization and globalization policies have reduced tariff rate and import and
export of technology has become common phenomenon. This has encouraged
developing countries to purchase foreign technology from the developed countries
and helped to compete in the international market. Developing countries have their
own advantages in terms of availability of resources, abundant labour; by adopting
foreign technology it can produce the products at lower cost than the developed
countries. For the developing countries invention and innovation is a time
consuming process and products become obsolete as and when the new products are
invented. So, even developing countries resort to import of technology rather than
depending on domestic research and development.
Therefore, import of technology is postulated to be positively associated with profit.
Capital Intensity
The electronics industry is capital intensive in nature. Capital stock consists of
machinery, tools, factory buildings and all kinds of industrial plants, raw material
etc. Development of an industry depends on these factors. In the Pre-liberalization
period gross fixed capital formation was mainly public investment, so the public
sectors enjoyed a degree of autonomy and gained major share of profit. The public
sector electronics firms are large in size and so experiences economies of scale.
Liberalization of economy encouraged private sectors (including foreign firms) to
participate in the industry. This has resulted in the increase of the overall capital
stock of the economy. Any cost reduction achieved in the capital goods industry is
48
always capital saving for the economy as a whole. Studies by Rosenberg (1963) and
Lall (1995) suggest that the use of Information technology results in the saving of
capital per unit of output. Since Electronics firms are highly capital intensive, it
would result in lower cost of production, more amount of output and higher profit
margin. Thus, the capital intensity is predicted to have a positive impact on profit.
Advertising
Marketing can be broadly defined to include all aspects of selling the product once it
leaves the plant where it is made. The product may be differentiated by distinctive
packaging, distinctive taste, distinctive sales outlet, and distinctive after-sales
service. Advertising is a means to influence the tastes and opinions in the direction of
their prodl!cts. Consumers will not know about firms' products unless they are told
(Donald A Hay et al., 1991 ). It is an efficient means by which producer spread the
information that the products is introduced in the market. Consumers have different
tastes and preferences for the products and they are not aware of the location from
where the products are available, price of the product and other product
differentiation. Advertisement helps to solve these problems and provide for easy
access. There is a relation between the amount of advertisement the firm does and the
potential market who will receive the information (Stigler, 1961 ). In the monopolistic
market it is used as an instrument of barrier to the rival firms, thereby enabling firms
to fix higher price and reap high cost margin. The more the investment in
advertisement, the more the product differentiation; it helps to reduce the absolute
value of the elasticity of demand and increases the price-cost margin. In Structure
conduct Performance, advertisement is seen as an element of conduct, structure and
also performance variable. As a conduct variable it influences the profit; it can also
behave as a part of performance influenced by industrial structure. So, this variable
may create simultaneous equation problem. Here advertisement is taken as a conduct
variable, expecting that advertisement positively influence the price-cost margin.
Structure
Structure (Concentration) is regarded as an important element in the Structure
conduct and performance paradigm. The concentration ratio shows the market power
and explains whether the industry is highly concentrated or low in concentration. The
features of the structure have been suggested by Bain, viz., Degree of seller
concentration, Degree of buyer concentration, Degree of product differentiation and
height of barriers to entry into the market. Structure can be measured with
49
Concentration ratio, Herfindahl index and Lorenz curve. The structure-performance
model hypothesizes that particular types of market structure is associated with
particular type of behaviour and influences the performance of the industry.
The earlier empirical work of Profit and concentration is done by Prof.. Bain. Using
eight-firm concentration ratios (CR8) for a sample of 42 US four-digit industries, he
found that after-tax profits as a percentage of shareholders' equity averaged 11.8 per
cent for those sectors with a CR8 greater than 70 per cent, compared with an average
of 7.5 per cent for sectors with lower concentration. This implied the positive
relationship between concentration and profitability (Donald A Hay et al., 1991).
Schwartzman (1959) carried out a study ofUSA and Canadian industries using profit
margins as the dependent variable, and found them to be significantly higher in more
concentrated industries. Collins and Preston's (1968) study using data from 1956-60
and 1963 with price-cost margins as the dependent variable revealed a positive
relation between concentration and the price-cost margin. Weiss (1974) tabulated and
reviewed around 46 concentration-profitability studies; a majority of these, using
regression analysis, found concentration to be a statistically significant determinant
of profitability. But Weiss' further study shows the weakened relationship between
concentration-profits and justified that this relation may possible in the period of
accelerating inflation. However, the results were questioned by Curry and George
(1983) provide a summary of 17 studies in which 15 studies found to have a negative
impact on changes in concentration (i.e. faster growth led to lower rises in
concentration). Therefore, Concentration is postulated to be positively associated
with price-cost margin.
Export Intensity
The promotion oflndia's export is an important objective of economic liberalization,
but India's export is not satisfactory in electronics hardware sector. Product cycle
theory (Vernon's 1966) explains that initially foreign production moved to other
countries because of cost competitiveness and servicing the host and third country
markets. Eventually, production shifted to the developing countries which may offer
competitive advantage as a production location. Most of the developing countries are
labour intensive and abundant in natural resources but scarce in capital. Foreign
participation in special economic zones and export processing zones increases cost
competitiveness which in tum strengthens export. According to Kojima (1978),
50
foreign investments are export-oriented and are designed to feed home country
demand. Cost of production is high in home (developed) country; this problem can
be sorted out by establishing a branch in developing country for supply of
intermediate goods. Ozawa (1992) emphasizes that the export-platform production
overseas by MNEs keeps moving from country to country on the basis of changing
factor costs. Frobel et al. (1980) emphasize foreign investment is intra industry
specification between the countries. MNEs locates certain types of manufacturing
operations away from home bases-especially to developing countries-to make use
of abundant supply of skilled and low wage labour (Kumar, 2002). LDCs enjoyed a
competitive advantage only in low and medium tech industries. However, enterprises
in medium tech industries with good R & D base networking with overseas firms for
technology imports and market information have been successful in their export
orientation (Willmore, 1992; Athukorala et al., 1995; Haddad et al., 1996;
Sidharthan, 2002).
The above theoretical explanation shows the importance of export and its
determinants, particularly foreign capital. It is interesting to expect relation between
greater export and profit in the electronics industry. India has strong competitors, viz.
East Asian and South East Asian countries which have liberalized much earlier. India
has all the advantages that these (East Asian) countries have; therefore, it can be
hypothesized that there is positive association between export and profit.
Impact of Liberalization
The argument for infant industry protection is an argument for temporary state
intervention to develop nation's industry and to protect from foreign competition.
However, the liberalization of the Indian economy has lead to reduction in the
protection of Indian industry; in other words it has been encouraging foreign
participation. Al-Saadon and Das (1996) refer to a situation where no-commitment
on the part of the local government turns out to be a better strategy than
commitmene. Planning should be made at central level and common policies should
be implemented all over the country without any hindrance from local government.
The ability of the local government to alter tax rates or reduce tax rates and
encourage joint venture (JV) agreement induces the MNC to offer a better share to
3 Here the author restricts government intervention to only in industrial activity. However, in social, security sector government participation is very much essential.
51
the local firm4• Grossman (1984) stated that very few countries would ever
consciously wish to specialize in unsi).illed labour, in other words they prefer for
skilled or trained labour. Foreign firms with a comparative advantage in
entrepreneurship, management, skilled labour and capital took over these functions,
replacing inferior 'local talent'. It may hinder employment growth but increase
output growth.
Above definitions emphasizes the importance of liberalization of the economy. The
learning process may be so long that the domestic entrepreneur may not be able to
catch up the foreign counterpart in the short period. Liberalisation helps in the
transfer of knowledge and its diffusion in the economy. This is very essential in the
electronics industry because it is technology intensive, and through knowledge
spillovers it can upgrade the existing technology. Hence, Liberalisation dummy is
expected to increase price-cost margin.
Central Excise Duty
Tax policies and incentives extended by the government have their impact on
production, employment, profit etc. The liberalization and globalization policies
reduced excise duty encouraged domestic private sector and attracted multinational
enterprises. The objective is to strengthen capital base, utilize domestic resources
optimally, generate employment and to be competitive in the international market.
India has skilled manpower but is scarce in capital resource unlike other developing
countries, viz. East and South East Asian countries. Though these countries were also
labour intensive, yet domestic policies have attracted foreign capital, making them
capital abundant countries. If electronics firms are to be competitive in the
international market domestic policies have to be in favour of private enterprises.
Thus, Central Excise Duty is hypothesized to be inversely associated with Profit.
Age of Firm
Age is an important factor for performance of firm. Age of firm is considered as a
proxy for learning by doing. The older companies are expected to have more
accumulated experience. The proportion of older capital dominates in the old firms;
new capital is less. The product quality of old firms are likely be poorer than the
product quality of new firms (Anita Kumari, 2008). However, it is value addition
4 Nirvikar singh and Sugata margit (eds.) Joint Ventures, International investment and Technology transfer, Oxford university press, New Delhi, 2003.
52
over the years that make the firms more competitive. The older firms maintain the
brand image by supplying qualitative products to the customers. As the demand for
the products increases, the profit margin also increases and surplus profit is re
invested for the expansion of the company, Research and Development, hiring
skilled labour, use of better technology etc. This results in the economies of scale and
given output can be produced at lower cost, which will increase the Price-Cost
margin.
Since, electronics industry is technology intensive, and technology becomes obsolete
very fast, Age of the firm is postulated to be negatively associated with profit.
Capital Import Intensity
Capital inte;nsity improves price-cost margm of firms, and profit performance
depends not only on quantity of capital but also quality of capital. Indian firms
collaborate with foreign companies with a view to strengthen existing capital.
Developed companies or branded companies refuse to extend their capital to
developing countries. However, the cost of production is low in developing countries
because of availability of resources and abundant labour. Developed countries can
exploit these resources and make profit by adopting their capital. So the capital
import fills the gap of capital scarcity and improves the economies of scale.
Therefore, capital import intensity is postulated to have a positive association with
profit performance of electronics industry.
Foreign Participation
As explained in literature, in the pre-reform period the infant industry argument was
adopted, allowing the state to intervene to develop the nation's industry and protect it
from foreign competition. However, economic reforms reduced the protection and
encouraged foreign participation. Foreign firms play a dominant role in the export
performance in developing countries (UNCTAD, 2002), which in turn increases
profit of firms. The ability of the local government to alter tax rates after the joint
venture (JV) agreement is signed induces the MNC to offer a better share to the local
firm (Nirvikar and Margit, 2003). Incentive for foreign participation ushers in a
competitive environment through entrepreneurship, management, skill labour, capital
stock and foreign technology. MNEs' market access and brand image improves
demand for the products. Several empirical studies emphasises foreign participation
for better performance (Sun, 2001; Liu and Shu, 2003). Other studies have shown
53
that foreign firms' p~icipation is to focus on host countries market rather than the
export.
Hence, foreign participation is assumed to be have a positive association with profit
performance.
2.3 Specification of the model and Source of Data
2.3.1 Model
Price-Cost Margin= f(Capital intensity, Firm size, Research and Development, Age
of firm, Import of technology, Capital import intensity, Central excise duty,
Advertisement intensity, Concentration ratio, Liberalisation dummy, Foreign
dummy).
2.3.2 Source of Data
Our primary source of data is PROWESS, compiled by the Centre for Monitoring
Indian Economy (CMIE). This data set covers the period from 1989 to 2007. The
liberalization dummy takes 0 if it belongs to the period 1989 to 1993 as pre-reform
and 1 if it belongs to 1994 to 2007 as post-reform period. The Foreign firm dummy
takes 1 if it belongs to the foreign company and 0 otherwise.
2.4 Empirical Findings of Performance and Structure of Electronics
Industry
Capital Intensity
Capital intensity and Profit are positively related and it is statistically significant at
five per cent level. It implies that the Indian electronics firms' probability as well as
propensity to profit is greater among relatively higher capital intensive firms. The
above result could have resulted from the following factors. Higher capital intensity
is the result of long-term accumulation of capital and technology. Capital stock
consists of machinery, tools, factory buildings and all kinds of industrial plants, raw
material etc. During the pre-liberalization, period gross fixed capital formation was
mainly public investment; so the public sectors enjoyed a degree of autonomy and
gained major share of profit. Since the public sector electronics firms are large in
size, they experienced economies of scale. However, the post-reform period
encourages private sector including MNCs. This has resulted to increase the overall
54
capital stock of the economy. It results in higher product quality and reduction of
marginal cost of production and increased profit margin.
Export Intensity
The coefficient of export intensity is positive with the Price-Cost margin and
statistically significant at five percent level. The explanation possibly lies in the fact
that India may be increasing and expanding a number of world class infrastructures
like SEZ and EPZ (required for the electronics hardware sector). This has been
initiated to compete in the international market particularly with East and South East
Asian countries. Since SEZ and EPZ are exempted from tariff duties the whole of the
earnings goes to the entrepreneur. This increases profit margin and induces
reinvestment and expansion of capital base. India's liberalization policies are
attracting private sector and MNEs, which in tum is resolving the problem of capital
scarcity. Many of the MNCs are established in India to utilize resources that are
available at lower cost and to serve either the parent company or the world market
that results in the increase of export of electronics goods.

Technology Import
There is positive relationship between import of technology and profit and it is
statistically significant at five percent~ge level. The possible explanation would be
that domestic research and development is not sufficient to compete in international
market. For the developing countries invention and innovation is the time-consuming
process and products become obsolete as and when new products come into the
market. Import of technology from developed countries, fills the gap of technology
between the technological requirements of the developing countries and availability
of technology in developed countries. India has its own advantages in terms of
availability of resources, abundant labour, and by adopting foreign technology it can
produce the products at lower cost than the developed countries. This in turn
increases profit margin of electronics firms.
Excise Duty
Excise duty and profit margin comes out as strong in the empirical analysis. Tax
policies and incentives extended by the government have their impact on profit. The
liberalization and globalization po~icies reduced excise duty encouraged domestic
private sector and attracted multinational enterprises. The objective is to strengthen
capital base, utilize domestic resources optimally, and generate employment and to
be competitive in the international market. Further reduce in excise duty increases
profit margin of enterprises.
Structure
As expected, the relationship between profit and concentration is positive and
statistically significant at ten per cent level. This results supports Bain (1951 ),
Schwartzman (1959), Collins and Preston (1968) and Weiss (1974). The results
explain that barriers against new entry can be seen to play a crucial role in
determining profit of existing firms. When there are barriers to entry, existing firms
can raise profit above the average level without inducing new firms' entry into the
market. Existing firms prefer long run profits; so, they keep price at low level and
enjoy command over the production of goods. However, concentrated firms gain
profit above average.
56
Impact of Liberalization
The relationship between liberalisation and profit is positive and statistically
significant at five per cent level. This implies that during the post-reform period
profit margin is increasing in electronics industry. This explains that the
liberalization policy, by encouraging Special Economic Zones, Export Promotion
Zones, Research and Development hub, Import of technology, Capital etc., have
been playing a vital role to develop the Indian electronics industry and obtain more
profit. Liberalisation helps the transfer of knowledge and its diffusion in the
economy. India is a developing country; so, invention and innovation is a time
consuming process and it becomes obsolete as and when the new products are
introduced in the market. Economic liberalisation allows import of capital and
technology from developed countries and facilitates the filling of the gap between the
technological requirements of the developing countries and availability of technology
in developed countries. This has resulted for profit gain during the post-reform
period.
Foreign Participation
As expected, foreign firms' participation and price cost margm are positively
associated and significant at ten per cent level. Economic reforms reduced the
protection and encouraged foreign participation. Foreign firms are entering the
Indian market either through equity shares or establishing their own branches. Their
objectives differ: to serve their parent company, to capture host country market, or to
compete in international market. Some firms follow all the strategies with a objective
of profit maximisation. Joint ventures with MNCs facilitate obtaining of capital,
technology, skill, business strategy etc. MNEs' market access and brand image
improves demand for the products. These factors ultimately lead to increase of profit
margm.
Insignificant variables
Size
The relationship between firm size and profit in the Indian electronics industry
comes out as weak in the empirical analysis. Firm Size comes out with insignificant
coefficient. It shows that the firm size doesn't affect the profit margin. A firm,
whether large or small, has its own advantages. The larger firms can absorb the
57
economies' unforeseen emergencies by maintaining equipment, stocks, cash, labour
etc. The big firms have control over suppliers, competitors and customers. On the
other hand, smaller or moderate firms would be flexible enough to adjust to the
economic fluctuations and can change production strategy, skill base and resources
according to demand for the products.
Research and Development
On contrary to expectation, there is insignificant and positive relation between R &
D intensity and Profit. It appears from the result that the Indian economy is not
emphasizing domestic technology (invention and innovation). Domestic research and
development is very essential to expand its base in the domestic market and then it
would not be difficult to compete in the international market. Many of the firms
established as hardware companies are involving in the software sector due to higher
profit margin. However, the large domestic market for hardware sector is inducing
companies to remain in hardware production. To be competitive in international
market research and development base is very important. The possible reasons for
insignificant relation between R & D investment and profit would be that only the
public sector companies established after independence are large-scale industries and
emphasized more on R & D activity. Indian science and technology institutions and
universities have been playing a major role in invention and innovation. However, it
has not been utilised optimally, because of import of technology would be available
at lower price than the domestic research and development. India has all the
advantages that China, East and South East Asian countries have, in terms of capital,
skilled labour, vast productive land, establishment of special economic zones and
export processing zones, but quality of infrastructure and suitable government policy
are not at par with these countries, to protect interest of private and foreign
entrepreneurs. Firms are gradually shifting from China to South East Asian countries
(Malyasia) and the development of R & D hub in India would atract these firms to
India.
Some of the other variables, viz. age, excise duty, advertisement intensity are
negatively related and firm size and R&D are positively associated but insignificant.
58
2.5 Electronics Industry's Concentration Ratio (Herfindahl Index)
The above analysis reveals that the price-cost margin is positive and significant with
structure (concentration ratio) capital intensity, export intensity, R&D, import of
technology, liberalization dummy and foreign dummy. However, Age, excise duty
and advertisement intensity are negatively associated but insignificant. Structure is
an important factor influencil)g performance of a firm. This section covers the
concentration (three firms) ratio of electronics industry at aggregate level as well as
at disaggregate level.
Market power permits higher levels of price-cost margin; it can be measured with
concentration ratio and the existence of barriers to entry (economies of scale, cost
advantages etc).5 Concentration may behave as a barrier against new entry. First,
high level of concentration may reflect as a high degree of firm-level economies of
scale. Therefore it functions as firm-level economies of scale. Second, new entry
firms may consider highly concentrated industry as more likely to take concerted
action against entry than a low concentration industry would.
2.5.1 Aggregate Electronics Industry
The Herfindahl index shows that the concentration of electronics industry has been
decreasing gradually due to the economic reforms. The pre-reform period saw
increase in the concentration in electronics industry. During the pre-reform period
the electronics industry was dominated by the public sector. During the post-reform
period till the year 1997 there was drastic decline; however, from 1998 it increased.
Immediate after reform the Indian private sector entered the electronics industry,
reducing the power of some of the large scale firms. Concentration ratio has recorded
slight declined thereafter except for the years 2001 and 2002. Further liberalization
of economy has encouraged MNEs, and their entry or establishing firm6 depends on
5 Impediments to entry into an industry can arise from factors specific to the industry concerned and from factors arising in the capital market.
6 MNEs' entry is properly panned. Initially they preferred to enter the industry through equity participation rather than establishing their own firms. Already existing firm has its own advantage in terms of R&D base, capital, market strategy etc. It helps foreign firms to capture domestic market in a short period. However, further liberalization of economy and establishment of SEZs, EPZs, EHP (Electronics hardware parks) etc., have been attracting foreign firms to establish their own branch.

the advantages they obtain. in India compared to other countries. In other words their
entry is properly planned7•

2.5.2 Electronics Industry Concentration at Disaggregate Level
The decline in the concentration in the communication electronics is much more than
the other electronics industry8. Decline in the concentration of communication
electronics is followed by the component, computer and the industrial electronics.
The consumer electronics industry is the only industry which is comparatively
constant; there is slight decrease during the 1990s and an increase thereafter at same
rate. During the pre-reform period the concentration has been increasing m
communication, component and computer electronics and a decline thereafter.
8 ITI {Indian Telecommunication Industry) was the largest industry in India. However, private sector participation particularly MNEs in the field of telecommunication has reduced its power and often loss is incurred. So, the competition has been increasing in the telecommunication industry.
60
Consumer and industrial electronics started declining during the pre-reform period;
the declining trend has continued during the post-reform period.

2.6 Relation between Price-Cost Margin, Wage Share and Central
Excise Duty
The above analysis reveals that the structure (Herfindahl index) has been decreasing;
in other words, electronics industry has been experiencing more competition. Here
we shall examine the relation between price-cost margin, wage share and central
excise duty.
In the previous section we have examined determinants of price-cost profit. Here
Profit is a dependent variable and independent variables are Capital intensity, Export
intensity, Firm size, R & D, Age of firm, Technology import, Capital import
intensity, Excise duty, Advertisement, Structure, Liberalisation dummy and Foreign
61
dummy. This section analyses relationship among Price-cost margin, Wage share and
Central excise duty. It begins with explanation of these concepts.
Price-Cost Margin
Profit is defined as the differences between total costs involved in making or buying
goods and the total income accruing from its sales. It may also be explained as price
per unit sold would be greater than the average or marginal cost. Accordig to Hawley
and A.C. Pigou, profit is a reward for risk and responsibility of entrepreneur9•
Disagreeing with this, Frank Knight (1922), stated that profit is a reward for
uncertainties rather than the risks which are known in advance. Similarly J.B. Clark
(1899) defines Profits as a dynamic surplus; the more the changes in the economy the
more the profit. In a stationary economy where no changes in conditions of demand
and supply occur, the prices paid to the factors of production on the basis of marginal
productivity would exhaust total value of production and no profit would accrue to
the entrepreneur. When the selling prices of goods exceed the cost of production the
profit increases. According to Stigler, Firms in a competitive industry can receive
profit because of a state of disequilibrium; these profits can arise even if all
entrepreneurs are identical, for disequilibrium can characterize a whole industry.
According to Joseph Schumpeter profit is a result of innovation. He has linked the
policy with the innovation. Any policy which reduces the cost of production and
increases the demand for the products is an innovat!on.
Strong case for profit occurrence is attributed to the monopoly, which is featured as
uneven size distribution, economies of scale, product diversification, patent, barriers
to entry, licensing, advertisement, etc. The opposite of monopoly is perfect
competition, where there is no scope for abnormal profit. As the market moves from
having a large number of firms to a few firms in the industry, the profitability will
rise from the normal level towards the super-normal profits. However, these are two
extreme cases; our study falls into neither of these markets. In other words it falls
somewhere in between. It is oligopoly or monopolistic market condition that
generally prevail in the market.
9 Here the author mentions risk factors, viz. holding of the assets, stock of materials and finished products, technological changes, price levels, marketing etc.
62
Central Excise duty
Tax policies and incentives extended by the government have its impact on
production, employment, wage, profit etc. In other words, higher excise duty has
negative impact on profit, employment and wages of labour. The liberalization and
globalization policies reduced excise duty with a view to encourage domestic private
sector as well as to attract multinational enterprises. The other objectives are to
strengthen capital base, utilize domestic resources optimally, generate employment,
and be competitive in the international market.
India has skilled manpower but is scarce in capital resource unlike other developing
• countries, viz. East and South East Asian countries. Though these countries were also
labour intensive, yet their favourable domestic policies have attracted foreign capital;
in the process they have become capital abundant countries. To enable electronics
firms to be competitive in the international market, domestic policies must favour
private enterprises.
Wages
Firms are expected to increase employment if their unit labour costs are decreasing
rather than increasing (Sharma, 2006). 10 The cost of capital with respect to labour
cost determines the employment growth. Employers who use more fixed capital per
worker reduce the number of employment but as the demand for labour increases,
they prefer casual, contract (non-regular) workers. This is because non-regular labour
cost is considered to be lower than regular labour. So, wages play a major role in
determining the profit of an entrepreneur.
10 Alakh N Sharma's (2006) study shows that in the case of total employment, 49 per cent of the sample firms which reported either an increase or decrease in labour cost, increased manual employment and employment is inversely related to the fixed capital per worker.

Analysis of price-cost margin of electronics industry at the aggregate level reveals
that there is a rise in the price-cost margin after economic reforms which allowed
trade and industry to participate at international level. This is broadly in agreement
with the results of Srivastava et al. (2001) and Goldar (2004). The income share of
the labour in value added is also rising. On the other hand the central excise duty has
been continuously decreasing. This suggests that the fall in the central excise duty
has resulted in raising not only the price cost margin but also the wage share of the
labour. The trend shows the price-cost margin and the wage share together
decreasing till 1992, whereas after 1992 to 2005 both are increasing; later both then
start decreasing. The wage share remains higher than the profit during the pre-reform
period whereas profit is higher than wage share during the post-reform period and it
continues till 2003. During the post-reform period till 2003 the profit and wage share
are inversely related; it may be that the labour power in terms of bargaining power
was lower than the pre-liberalization period. This reveals that the economic
liberalisation through labour reform reduced the labour power. The Multinational
Enterprises' entry either through equity participation or establishing their companies
has led to the rise in the share of the labour wages and they kept their profit margin
low to compete in the Indian market. Electronics industry requires skilled labour; to
attract highly skilled or trained labour foreign firms paid high wages. Firms targeting
65
long-run profit keep their profit margin at low level. This is clearly borne out by the
present study.
After 2005 the profit margin declines; the wage share also follows same path. On the
other hand, central excise duty has been declining continuously.

Consumer Electronics
During the reform period the consumer electronics industry has been experiencing an
inverse relation between its profit and wage share. As the profit increases the wage
share decreases. On the other hand, during the pre-reform period though both were
66
continuously declining the wage share remains higper than the profit, and the profit
touches a low much earlier than the wage share. This clearly explains that the trade
unions were much stronger in the pre-reform period than in the post-reform period.
On the other hand, Central excise duty is declining continuously. The benefit from
the decline in the Central excise duty is reaped by the entrepreneurs alone. ·In other
words, it is not shared with the labourers. As the classical economists explain
entrepreneurs' surplus will be reinvested in industrial activity and the capital
accumulation takes place, and this will lead to the growth and development of the
industry. So there is possibility of growth and development of consumer electronics
industry in India.

The decline in the Central excise duty resulting to the increase in the Wage share.
This is a contrast to the consumer electronics industry. The increase in the wage
share is much more than the increase in the profit. Till 1998, the average wage share
is lower than the profit, but after 1998 the average wage share increases much more
than the profit. In other words, the overall increase in the wage share is much more
than the increase in the profit, though both increase. This implies that the benefit
67
obtained by decline in the central excise duty is shared by both the entrepreneur and
labour, though the labour share is much more than the profit of the entrepreneur.
During the pre lib~ralisation period both the profit and the wage share are declining.
During the post-reform period the wage share experience a increasing trend and
profit has declined after the year 2005. It implies that Industrial electronics industry's
labour union is much stronger than consumer electronics industry.

In the computer electronics industry, the profit and the wage share are inversely
related to the central excise duty. As the Central excise duty decreases the Profit and
the wage share are increasing. The profit share is much more than the wage share.
During the post-reform period the profit share and the wage share are almost
inversely related. In other words, as the profit share increases the labour share
decreases and vice versa. During the pre-reform period, the wage share remains high,
whereas in the post-reform period profit share remains higher than the labour share.
In the year 1995 the labour share recorded a low and the profit remains high. In the
computer industry the difference between labour share and the profit is very high, but
68
later it is reduced and convergence occurs. It reveals that since computer is a highly
competitive product and there is large domestic demand for it there exist an
understanding between the labours and the entrepreneur. This is very essential
because East and South East Asian countries are in a dominating position in this
industry. China and Malaysia have specialized in this industry; large scale electronics
hubs are located in these regions. India has all the advantages that these regions have;
so there are possibilities that these established MNEs will shift from China to
Malaysia and from Malaysia to India. Another important factor is that India is known
for its software sector; to develop the software sector, the hard ware sector is very
essential. The growth of software sector will be hindered by a complete dependence
on the import of hardware. So, hardware base is very essential and there should be
proper understanding between employer and labour in the sharing of the total
revenue.

The communication electronics industry has been experiencing an increase in profit
and wage share. There is slight decrease in the central excise duty. Pre-liberalization
period profit is higher than the wage share, and during the post-liberalization period
the wage share remained not only high but also increased drastically. This reveals
that the Profit and the wage share are almost inversely related. The increase in the
profit is very less compared to the increase in the wage share. It reveals that the
major share of the profit is taken away as the share of the labour. It also explains that
to be competitive at the global level, profit has to be kept at minimum level and
skilled labour maintained by paying high wage. This problem could be solved by
increasing the capital intensity through the import of capital and technology.

In the component electronics industry the profit is not only inversely related to the
wage share but also with the central excise duty. In other words as the Central excise
70
duty is decreasing there is a slight decrease in the wage share and the increase in the
profit. During the pre-liberalization period the average profit is lower than the
average wage share; due to the impact of liber(!.lization, the average profit has been
increasing continuously and the wage share has been decreasing. The difference
between profit and wage share is quite hi'gh in the year 1995 and 2004. But the
difference in the year 2004 is much more than the remaining years.
It shows that the electronics industry's profit is inversely related to the wages and
Central excise duty. The trend of the profit and the wage share are reversed due to
the impact of liberalization policy.
Summary
In this chapter, the analysis focused on the electronics industry's market behaviour
through structure-conduct-performance paradigm, during pre- and post-reform
period. Further, analysis continues importance of structure (Herfindahl index)
variable at aggregate and disaggregate level. Disaggregate level consists of consumer
electronics, industrial electronics, computer electronics, communication electronics
and component electronics industry. Finally, the analysis continued to look at the
relation among price-cost margin, wage share and central excise duty. The main
findings of the study are summarized below:
Study of S-C-P paradigm or determinants of price-cost margin has been carried out
by estimating panel data regression equation, Random Effect, and GLS method. The
analysis shows that structure, capital intensity, export intensity, import technology,
liberalisation dummy and foreign dummy are positively significant. Central excise
duty is negatively significant. These results implies that the economic reforms leads
to increase in capital stock, import of technology, foreign participation, export
processing zones etc. Liberalisation of economy helps in the transfer of knowledge
and technology diffusion in the economy. It allows import of capital and technology
from developed countries and facilitates the filling of the technological gap. Joint
ventures with MNCs facilitate obtaining of capital, technology, skill, business
strategy etc. MNEs' market access and brand image improves demand for the
products. The structure (concentration ratio) is also found to be positively associated
with profit. These factors resulted in profit gain during the reform period.
71
Some of the other variables, viz. age, advertisement intensity are negatively related
and firm size and R&D are positively associated but insignificant.
The Herfindahl index shows that the concentration of electronics industry has been
decreasing gradually due to the economic reforms. The pre-reform period has
experienced increase in concentration in the electronics industry. During the pre
reform period electronics industry was dominated by public sector. During post
reform period till the year 1997, there has been a drastic decline; it increased in the
year 1998. Immediate after the reform period the Indian private sector entered the
electronics industry, reducing the power of some of the large scale firms.
Concentration ratio has recorded a slight decline thereafter except during the years
2001 and 2002. Further liberalization of economy has encouraged MNEs and their
entry or establishment of firms resulting in the further reduction of the concentration
ratio.
The decline in the concentration in the communication electronics is much more than
the other electronics industry. Decline in the concentration of communication
electronics is followed by the component, computer and the industrial electronics.
The consumer electronics industry is the only industry which, comparatively,
remained constant; there is a slight decrease during 1990s and an increase thereafter
at same rate. During the pre-reform period the concentration has been increasing in
communication, component and computer electronics and a decline thereafter.
Consumer and industrial electronics started declining during the pre-reform period
and the declining trend has continued even during the post-reform period.
Analysis of price-cost margin of the electronics industry at the aggregate level
reveals that there is a rise in the price-cost margin after economic reforms. The
income share of labour in value added is also rising. On the other hand, the central
excise duty has been continuously decreasing. This suggests that the fall in the
central excise duty has resulted in the rise not only of the price cost margin but also
the wage share of the labour. The trend shows the price-cost margin and the wage
share together decreasing till 1992, but from 1992 to 2005 both increase; later both
started decreasing. The wage share remains higher than the profit during the pre
reform period whereas profit is higher than wage share during the post-reform period
and it continues till 2003. During the post-reform period ti112003 the profit and wage
72
share are inversely related; may be the labour power in terms of bargaining power
was lower than the pre-liberalization period. This reveals that the economic
liberalisation, through labour reform reduced the labour power. The Multinational
Enterprises' entry may have led to the rise again the share of the labour wages; they
kept their profit margin low to compete in the Indian market.
Consumer Electronics
During the reform period the consumer electronics industry has been experiencing an
inverse relation between its profit and wage share. Though both were continuously
declining during the pre-reform period the wage share remains higher than the profit.
This clearly explains that the trade unions were much stronger in the pre-reform
period than in the post reform period. The benefit from the decline in the Central
excise duty is reaped by the entrepreneur alone.
Industrial Electronics
In contrast to the consumer electronics industry, decline in the Central excise duty
resulted in the increase in wage share. Till 1998, the average wage share is lower
than profit, but after 1998 the average wage shares increases much more than profit.
This implies that the benefit obtained by the decline in the central excise duty is
shared by both entrepreneur and labour, though the labour share is much more than
the profit of the entrepreneur. It implies that Industrial electronics industry's labour
union is much stronger than consumer electronics industry.
Computer Electronics
As the central excise duty decreases the Profit and the wage share increases. During
the pre-reform period, the wage share remains high, whereas in the post-reform
period the profit share remains higher than the labour share. Later the differences get
reduced and convergence takes place. It reveals that since computer is a highly
competitive product and there is large domestic demand for the computers, there is
an understanding between the labours and the entrepreneur. This is very essential
because East and South East Asian countries have a dominant position in this
industry. Another important factor is that India is known for software sector; to
develop the software sector, the hard ware sector is very essential. The growth of
software sector may be hindered by complete dependence on the import of hardware.
73
So, hardware base is very essential and there should be proper understanding
between employer and labour in sharing the total revenue.
Communication Electronics
There is slight decrease in the central excise duty. Pre-liberalization period profit is
higher than the wage share, and during the post-liberalization period the wage share
remained high. This reveals that the Profit and the wage share are almost inversely
related. The increase in profit is very less compared to increase in wage share. It
reveals that the major share of profit is taken away as the share of the labour. It also
explains that to be competitive in global level, profit has to be kept at minimum level
and skilled labour maintained by paying high wage. This problem could be solved by
increasing the capital intensity through the import of capital and technology.
Component Electronics
As the central excise duty decreases there is a slight decrease in the wage share and
increase in profit. During pre-liberalization period the average profit is lower than the
average wage share. Liberalization led to continuous increase in the average profit
and the decline in wage share. It shows that the electronics industry's profit is
inversely related to the wages and central excise duty.
