Abstract
Implementation of a new technology generally affects the economy indices including production costs and
employment. Although the implementation of nanotechnology may influence the economy in several ways, this
paper focuses on its impact by processing the production. Hence, it is attempted to measure its effects on the
production costs and labour force employment. Using the Input-Output table of Iran for the year 2001, the results of
simulation by an extension in Input-Output model demonstrates that the nanotechnology implementation will reduce
the cost of production and labour force employment through technical coefficients, labour, capital consumption, and
the imports shares in supply.

1. Introduction
Recently, people witnessed the emergence of a new phenomenon, called nanotechnology,
in different parts of their lives. Many investigations like Anson et al. (2008) were carried out,
focusing on the importance of this phenomenon as holding the potential to significantly alter the
structure of production across many industrial settings in the future. With respect to its
capabilities, nanotechnology is anticipated to be the cause of the next economic revolution of the
world which will affect all different aspects of people's lives (Roco 2001, Compa and Hullmann
2002, Tegart 2004 and Al-Mutaz 2009).
As the key driver for economic success in the future, nanotechnology is the first priority
of science and technology in countries such as US and UK. So its development is supported by
the government of these countries through especial programmes (Roco 2001 and Pitkethly 2008).
For the reason that this phenomenon started in the last decade of the 20th century, it is too early
to judge the results of its implementation in any part of life accurately. However, a few aspects
of the results can be anticipated to some degree.
Since the implementation of nanotechnology affects the production process, it seems this
phenomenon leads to several changes in the economic and social affairs of people. Among many
effects, a decrease in the costs of production and in the employment of labour force generally are
said to be two positive and negative results of implementation of a new technology, respectively.
There are some studies that are concerned with the effects of nanotechnology
implementation on cost efficiency in the production process. For example, Greg (2004)
attempted to provide a strategic policy intelligence to enable economies to improve their
strategic planning so as to deal with the future changes stemming from nanotechnology. The
balance between the potential benefits and risks of nanotechnology were verified by Roco
and Bainbridge (2005) in various themes including economic impacts and quality of life.
Hullmann (2007) analysed the economic effects of nanotechnology on markets, funding,
companies, patents, and publications. Siripala et al. (2009) demonstrated, through
electrodeposited Cu2O films, that it is possible to prepare low cost solar cells that have nano-
structures. Implementation of nano-engineered materials for sustainable and cost effective water
was studied by Likodimos et al. (2010). Finally, considering the quantitative analysis of public
value in science and innovation, using nano-scale science and engineering to provide a credible
and robust basis for policy analysis was proposed by Fisher et al. (2010).
In addition there are some studies on the effect of nanotechnology implementation on
employment of labour force. It is notable that most of these studies focused on the composition
and level of labour force qualification or new fields for labour force employment. For instance,
Abicht et al. (2006) notified in the case of nanotechnology implementation, demand for staff
with qualifications below university level is presently at a low level, so a nanotechnology
qualification is required for employees. However, it also is possible to find some new fields of
activities in areas such as marketing and sales for a qualification below university level. In
addition, based on the estimation by National Science Foundation of the United States, about 2
million nanotechnology workers will be needed worldwide by 2015. It is notable that, along with
new companies, many already well-established companies such as Bayer, BASF, General
Electrics, Philips, all of which were founded before 1900, have now expanded their technology
portfolio to nanotechnology in order to remain in this hot competition (Hullmann 2007). The
relationship between human capital levels and nanotechnology development was investigated
through the number of graduates in the field of science and engineering and the number of
patents in Burnett and Tyshenko (2010) study..
To analyse the effect of nanotechnology implementation in manufacturing process,
although this research failed to find any trace in I-O studies, in similar cases, there are some
studies in which the effect of a new technology is investigated using the I-O technique. Leontief
and Duchin (1986) investigated the impact of computer-based automation on the demand for
various types of labour in the US from 1963-2000. A dynamic input-output framework with a
capital requirement matrix was employed to show how the new technology affects input-output
coefficient. Some changes were considered in technical parameters, capital expansion due to
sectors’ capacity increment, and in replacement requirements and labour inputs. In another study,
the effect of the diffusion of micro-electronic-based new technologies on the level and
composition of employment in West Germany was investigated based on modification in
Leontief and Duchin (1986) model, by Kalmbach and Kurz (1990). To this end, a dynamic I-O
model focuses on investment attempted to investigate the effect of change diffusion on
endogenous final demand over time. The explicit-new-technology approach as a tool for
analyzing spontaneous market forces and direct planning from prototype economies to that of the
UK was used by Ryaboshlyk (2006) study. To use the model for planning affair, the future value
of private consumption was maximized with respect to constraints in capital stock, land, and
employment required due to change in the technology of some sectors. And finally, the result of
a long term specific technology change on economic structure was simulated using a dynamic I-
O model in which the technical progress and development were endogenous (Pan 2006). The
model was implemented to modify the Leontief (1970) open dynamic I-O price model with
respect to specific depreciation rate, obsolescence rate and idle rate of capital.
Thus, although similar to other new technologies such as machines, computer and
internet, it is possible that a considerable number of new jobs be created in the countries, it
seems the reduction in production costs due to less raw materials and energy in implementation
of nanotechnology leads to a reduction in job creation for labour force. Therefore, this paper
intends to investigate the results of changes in this technology in production process upon
production cost and employment in the economy.
It is notable in the above studies a dynamic input-output model reveals the process of
changes over time. It would consider the result of technology changes on equipments through a
period. But this paper employed a comparative static analysis to measure the effect of
nanotechnology implementation in production process in two points of time. It would release the
effect of technology changes in production process on production cost and employment from
change in final demand items that can be due to any reason like capital formation.
The second contribution of the paper is to consider any change in the share of imports
that is important in employment and ignored in the previous studies. To this end, an extended I-O
model is developed to meet these purposes. Since it is too early to see the result of this
phenomenon on the production cost and unemployment crisis, the model is employed to simulate
the implementation of nanotechnology in all sectors on these indices.
This paper includes six sections. The following section is devoted to a general overview
of the nanotechnology impacts upon an economy. A theoretical study of technological changes is
presented in the third section. The fourth section covers methodology of the research. The
specification of database and the result of using the methodology and database are discussed in
the fifth section. And finally, the conclusion of the research will end the paper.
2. A general overview of the nanotechnology
Nano, meaning the small in Greek language, is frequently used to refer to one billionth of
a quantity in many sciences, as in Physics. Since dimensions of an atom are about 10 nano
meters, this word is popular in studying atoms and molecules as well. It is used in the field of
sciences and was originated by Richard P Feynman’s classic talk on December 29th 1959 at the
annual meeting of the American Physical Society at the California Institute of technology
(Carotenuto (2004), Greg (2004) and Whitman (2007)).
Later, this idea was adopted by others, and as a result, the carbon tubes as the first
products of nanotechnology implementation in the production process were obtained in 1991.
Since 1991, several products have been generated using nanotechnology implementation in food
products, clothes, transistor motors, and in many other goods and services. Recently, the nano-
scale sciences and engineering have provided new ways for engineering materials so the
resultant materials are expected to enable technologies to advance in the development and
application of nano-medicine (Venugopal et al.(2008)).
In a very simple definition, nanotechnology is the engineering of functional systems by
control of materials at a molecular scale. The main difference between nanotechnology
compared with others lies in the material scale and structure of this technology. Thus, it is related
to the production process which is an important effect of implementation of this phenomenon
(Roco 2001).
Nanotechnology offers ways to create smaller, cheaper, lighter, and faster devices that
can do more things, act more accurately, use fewer raw materials and consequently consume less
energy. It vastly improves the manufacturing process. This improvement leads to a reduction in
the production cost of commodities. It is expected nanotechnology have an important impact on
the economy and society in the 21st century (Roco 2001, Compa and Hullmann 2002, Greg
2004, Al-Mutaz et al. (2009).
Several studies about nanotechnology have been carried out in assessing its economic
benefits in production process. For instance, using the nano-imprint lithography techniques,
Luesebrink et al. (2005) presented low-cost, high throughput micro- and nano-devices
fabrication. Wegner and Jones (2006) advised the R&D investments must be made in the science
and engineering at the nano-scale as to produce advanced and cost-competitive cellulose and
lignocelluloses-based products. Venugopal et al. (2008) referred to Electro spinning technique as
simple and cost-effective in preparation of nano-fibers and macro porous scaffolds for drug
delivery and tissue engineering applications. Effective reduction in water production cost was
emphasised in Al-Mutaz et al. (2009).
In addition, Center for Responsible Nanotechnology (not dated. a) referred to nano-
manufactured extremely low cost water in a condition where approximately half of the world's
population lacks access to basic sanitation, and almost 1.5 billion people have no access to clean
water. Moreover, thanks to nano-technology, an entire supercomputer can now fit into a cubic
millimeter and cost a small fraction of a cent. Environment and mines are two other areas
wherein a more compact and cheaper manufacturing allows for improvements that make possible
a faster development at a lower cost. West (2008) notified the nano-products can be prepared and
applied with higher cost efficiency and will conduct electricity at a higher rate than it is currently
possible. It can also bring down the farm production costs and make possible a more efficient use
of inputs like water, fertiliser nutrients by eliminating wastes. There are also many other
researches like Bowers and Cernac (2008) that reported nanotechnologies reduce production cost
through more effective use of inputs.
Another result of nanotechnology implementation concerns the high quality of its
products. It generally concerns producing new and/or improved materials. In addition to many
high-quality products at a very low cost, it will make possible creating new nano-factories at the
same low cost and at the same rapid speed. For example, nano-factories can create products
vastly more powerful than they already are. Electrical power can flow with 10 times the
efficiency and about 108 times the density. Computers can be 1012 times smaller and use 106
times less power. Materials can be about 100 times stronger. This means that most human-scale
products would consist almost entirely of empty space, reducing weight, material requirements,
and the cost (Center for Responsible Nanotechnology, not dated. b).
It is notable that apart from many typical characteristics such as durability, hardiness, and
strength, as well as non-harm environmental effects of nano products that are related to the
quality of nano products, implementation of the nanotechnology has a considerable effect on the
production procedure too. On the other hand, it is expected that the implementation of this
phenomenon lead to a new relationship among the production factors.
3. A theoretical study
3.1. The input-output analysis of nanotechnology
The demand for product is classified into intermediate and final parts in an ordinary I-O
table. Whereas the intermediate demand is placed as to produce new commodities, the final
demand originates from domestic or foreign institutes. Note that, in fact, all products are
demanded by final demand directly or in the form of other products, indirectly.
In a similar classification, the effects of implementation of nanotechnology on an
economy can be classified into two categories. A part of its implementation effects could be
traced back to the technological changes of production sectors in the production process of
commodities. Since any change in the production procedure generally affects the economic
factors’ relationship, it is expected the implementation of this phenomenon lead to a new
interrelationship among production factors.
Note that it is expected the new technology have different effects on the relationship of
production factors. As the first effect, it is expected the new technology affect the relationship of
production factors through types and amount of raw materials that are required for a certain level
of production. The second effect of implementation of a new technology is related to the level
and the composition of primary factors that are required for a certain level of production.
Another effect of the new technology relies on the share of primary factors and intermediate
goods and services in the inputs that are required for the products. And finally, the new
technology affects the ratio of imported goods and services to the intermediate inputs for
products.
The second group of nanotechnology effects on an economy is due to the above-
mentioned ad hoc characteristics of nano-products. In fact, this category of features is a result of
the quality of products that influence the final demand part of an I-O table. On the other hand,
the second group characteristics of nanotechnology effects on an economy are related to the
quality of commodities that affect the economy through final demand that contains the
exogenous part of an I-O model.
3.2. A microeconomical analysis
Based on the Leontief production function technology that runs in the I-O model, the
production factors composition is fixed through all levels of products. Composition of the
production factors is valid for a certain technology. On the other hand, any change in the
production technology will bring about changes in the production function too.
In an I-O model, the new production function would have a Leontief form as well.
However, it would have a different curve and consequently a different isoquant curves. With
respect to the intermediate and primary factors, supposing that the price would remain stable, the
two groups of these curves can be shown simultaneously.
Figure 1 displays a very simple isoquant curves before and after the technological
change. Bringing the two cases together, the broken lines and solid lines are assumed to be
associated with the phase before and after a technology improvement, respectively. Each
function has its especial expansion path that its slope shows the composition of production
inputs. The diagonal parallel lines are the budget-income isoquant curves.
Fig. 1. Isoquant curves relating to technology change.
In Figure 1, items In1 and In2 denote the size of production costs and Q1 to Q4 the level of
products, in which In2 > In1 and suppose that Q4 ≥ Q3 and Q2 ≥ Q1. As it is shown, although In1 is
the same for the two isoquant curves, due to new technology implementation, Q2 ≥ Q1 and
although In2 is the same for the two isoquant curves, yet the implementation of the new
technology leads to Q4 ≥ Q3. On the other hand, with respect to production factors price
constancy, an improvement in the production technology leads to a new production function that
enables the producer to attain a higher level of production for a certain cost. This phenomenon is
available by a reduction in consumption of intermediate and primary factors or change in the
composition of production factors that are required for a certain level of production.
4. Methodology
A standard price model is employed to measure the results of a change in the production
technology. Irrespective of the alteration in the quality of products that may occur due to using a
higher technology, this paper focuses on the effect of the technology improvement on the price
of products and employment. To meet the mentioned effects of implementation of the new
technology, the standard price model is developed.
To this end, the following extended price model is employed to study different effects on
the price of products:
(1)
where P denotes the column vector of price indices for sectors, the transpose of A, the
technical coefficient matrix, the diagonal matrix of the share of imports in supplying the
sectors, Pm the column vector of price index for imports and the column vector of share of
primary factors in the production inputs.
To show the effects of new technology, as the first step, we start to study the effects of a
new technology on the decrease in the intermediate consumption of production sectors. Thus,
although a reduction in the intermediate consumption affects its share in total inputs, by ignoring
other changing, it is assumed the new technology only affects the technical coefficient elements
of the model.
The new technology can affect all intermediate inputs of sectors, so the transpose of
the technical coefficient of the relationship (1) changed to as the relationship (2). the
transpose of C, with the same dimension of in which its elements cijs show the effects of the
new technology on the corresponding technical coefficients of the related sector, is expected
mainly to be less or equal to 1. By a Hadamard Product , is calculated in the
relationship (2) as fallows: 1
1 The Hadamard Product of two matrices M=[mij] and N=[nij] with the same dimensions is the entry-wise product M°N=[ mij× nij] which has the same dimensions as M and N (Horn 1990).
(2)
Thus, with respect to this assumption, the relationship (1) changes as follows:
(3)
As the second step, it is assumed the new technology changes the share of domestic and
foreign goods and services in the supply of products. To consider this change, it is assumed bis
change into . With respect to the value of dis, the result of the new technology may lead
the country to become more self sufficient, , or more dependent, as , to the foreign
countries.
Thus, the second assumption of the model changes the relationship (3) as follows:
(4)
is the diagonal matrix of dis.
In addition, the new technology affects the primary factors of production sectors. Its
implementation causes two different changes concerning the primary factors of the model. On
the one hand, it may change the ratio of primary factors to each other. On the other hand it
changes the share of primary factors in total input of the sectors. Thus, the third step stresses
these effects as well. To do so, let us decompose , the share of primary factors, into some
components:
(5)
ki and li denote the level of capital stock and labour force required for a unit product,
respectively. v and w refer to the prices of capital stock and labour force, respectively.
Using the new technology may affect the value of ki and li of the sectors. Let fi and ei
denote the coefficients to measure the change in these factors due to implementation of the new
technology. Consequently, and . Thus:
(6)
refers to the column vector of the share of primary factors after the new technology
implementation, including and the two column vectors in which and are the size of
capital stock and labour force of sectors after the new technology implementation, respectively. k
and l denote the two columns of in the relationship (5). Finally, and denote the diagonal
matrices of fi and ei, respectively.
Thus in the third step, the relationship (1) to measure the effect of new technology
implementation on the prices of sectors is as follows:
(7)
To examine the effects of the new technology on the prices of sectors for the given case
in which, for the sake of simplicity, for example all intermediate input of sectors plunge with the
same ratio, values of and should be specified. However, ignoring this presumption
leads to calculation of , , and after any technological improvement.
A similar process is required to measure the change in the level of employment for
sectors. To do so, we consider the share of imports in the supply of sectors in a general
employment relationship:
(8)
L denotes the column vector of Li, the level of employment in different sectors, the diagonal
matrix of direct employment coefficient of labour force, Q the column vector of total products of
sectors, and F the column vector of final demand of sectors.
Irrespective of the change that may happen in the construction of the final demand of
sectors, like the price model, implementation of a new technology can influence this relationship
in four ways. Considering the above mentioned effects, the relationship (8) changes into the
relationship (9) as follows:
(9)
where is a column vector that contains the size of labour force in sectors after the new
technology implementation.
5. Implementation of the model
The model is employed to study the effects of nanotechnology implementation in Iran. A
17 to 17 sectors I-O table of Iran for the year 2001 is used as database (Statistics Center of I. R.
Iran, 2006). Using the employment data of sectors for the years 1986, 1991 and 1996, the
number of labour force in sectors is estimated for the year 2001.
Results of the change in technical coefficients using the relationship (3) are simulated in
table 1. In the case where the new technology affects only the technical coefficient of sectors, a
certain reduction in intermediate inputs of all sectors leads to a reduction in the Producer Prices
Indices (PPI), calculated by Laspeyres method. In addition, although there is no evidence that
nanotechnology affects all sectors similarly, it is assumed c ijs for all i and j are equal to 1, 0.95,
0.90 to 0.05. However, the differences of PPI for different levels of cijs demonstrate that the
effect of reduction in the technical coefficient of sectors on the PPI decreases.

The relationship (4) enables the researcher to study the result of change in the share of
imports due to nanotechnology implementation. It is notable, although using a new technology
may increase or decrease the share of imports in supply, yet table 2 shows the effects of a new
technology implementation on PPI when the new technology leads to a reduction in technical
coefficient and imports shares in supply. It shows the effects of Reduction in the size of the
Imports Shares in Supply (RISS) on the PPI for three levels of cijs. The column differences
explore the reduction in PPI as a result of 0.05 RISS.
It is notable, though compared with the reduction in cijs, the RISS imposes negligible
effects on the PPI, and as it is expected, its effect is dependent on the size of cijs. Due to the
nonlinearity of in relationship (4), a 0.05 RISS has different effects on the PPI. As a result of
a comparison between the change in PPI through different columns of table 2, it is explored the
effects of RISS on the PPI has an inverse relationship with the level of imports shares. However,
although the size of cijs affects the impact of RISS on the PPI, as demonstrated in table 2, its
effect has no fixed trend on PPI. So an analysis of the amount of differences in PPI shows that a
reduction in the value of cijs from 0.95 to 0.50 leads to an increase in the effects of RISS on PPI,
whereas a reduction in the value of cijs from 0.50 to 0.05 leads to a considerable decrease in the
level of differences in similar cases of dis.

The effects of different factors are examined in relationship (7). With respect to its form,
it can be deduced that the effect of a new technology implementation on the PPI can be
decomposed into three parts. Table 3 demonstrates a case in which cijs and dis are equal to 1. In
addition, the new technology has affected only the eis or fis or both of them. As it can be seen,
due to the linear form of these factors in the model, firstly, the effect of a specified decrease in
the value of eis and fis are constant for any level of these factors. Secondly, the effects of a
specified reduction in the value of these factors on the PPI are independent of the others. So the
effect of a reduction in the value of eis along with fis on PPI is equal to the effect of eis and fis on
PPI separately.

To investigate the effects of reduction in technical coefficient and RISS as well as eis and
fis, table 4 demonstrates the effects of eis and fis on PPI in the case where cijs and dis are equal to
0.75, 0.5 and 0.25. As it is shown, implementation of a more efficient technology that leads to a
higher reduction in cijs and dis, leads to a higher level of reduction in PPI. This is due to cijs and
dis that are constant value and also because of the multiplier for eis and fis in the relationship (7),
where a reduction in the value of these parameters leads to a reduction in PPI and consequently
the size of their differences.

Table 5 measures the reduction in employment for labour force due to using a new
technology. As it is shown, the effects of a 5% Reduction in Labour Force Coefficient (RLFC)
due to the new technology implementation are displayed for different levels of cijs and dis.
Because of the linear relationship of eis with the value of labour force employment in
relationship (9), a 5% RLFC has a constant effect on employment reduction in different levels of
eis. However, the effects of RLFC on the reduction in labour force employment are dependent on
the values of cijs and dis.

And finally table 6 investigated the effects of a reduction in dis on labour force
employment. To do so, it is assumed eis are fixed at 1. As expected, cijs and dis have inverse
effects on the labour force employment. Thus, any decrease in the value of dis has a positive
effect on the number of labour force employment. Accordingly, in this case where eis are equal
to one, a decrease in dis will lead to an increment in the level of employment. In addition, if the
new technology does not change the technical coefficient, then any RISS would lead to an
increase in the level of employment. However, for the cases in which the new technology leads
to a reduction in the value of cijs to 0.75 or 0.50, the results of simulation showed that up to 50%
reduction in dis cannot compensate the reduction in employment for labour force.

6. Concluding remarks
It was assumed the world would witness some striking changes in future, when using the
nanotechnology well penetrates all industries. Irrespective of its making a change in the level of
consumption and the quality of commodities or environmental effects, like any other technology,
it is expected the implementation of nanotechnology will have some positive as well as negative
effects on the social and economic aspects of people's life, through the process of production.
However, among all impacts, this paper focused on employment and Producer Prices Indices.
Based on the results of the research, implementation of the nanotechnology affects the
production cost through several ways. It was demonstrated that an improvement as a result of
using this technology in the technical coefficients leads to a reduction in the PPI of the economy.
Implementation of the nanotechnology affects the PPI through the share of imports in the supply
of products that is dependent to the economies. However, like the technical coefficients it has
nonlinear relationship with PPI. Moreover, the result of the research demonstrates that the
change in labour and/or capital stock contribution, as a result of nanotechnology implementation,
has a direct linear relationship with PPI as well.
In addition, a related model was developed as to simulate the effects of nanotechnology
implementation on labour force employment. Like PPI, the results of simulation of the model
demonstrates, the change in the size of direct coefficients of labour force that imposes a linear
direct effect on the size of employment of labour force, is related to the values of cijs and dis.
However, unlike PPI, changes in cijs and dis have inverse effects on the amount of employment
for labour force.
