Effect of information and communications technology on stock market development: evidence from emerging markets and high-income economies.
Ngassam, Christopher ; Gani, Azmat
Abstract
This paper investigates the links between information and
communications technology (ICT) and stock market development in a sample
comprising of high-income and emerging market economies. The empirical
results of the least squares dummy variable model confirms that personal
computers and internet hosts as the two ICT variables having strong
positive effects on stock market development. The results also revealed
strong positive effects of market capitalization and credit to the
private sector as non-ICT contributors to stock market development.
Controlling for income and technological differences, our results lead
us to conclude that emerging market economies have already seized an
opportunity to leap frog the high-income countries that is, by going
straight from underdeveloped networks to fully digitized networks,
bypassing the traditional analog technology. As such this leap frogging
is positively enhancing their stock markets. Some policy implications
are drawn.
1. Introduction
Numerous studies pertaining to the literature on stock market
development have emphasized the impact of several financial and economic
variable (see for example, Levine, 1991, p. 1445; Bhide, 1993, p. 2;
Atje and Javanovic, 1993, p. 632-38; Harris, 1997, p. 139-140; Levine
and Zervos, 1998, p.3-4; Beck, Levine and Norman, 2000, p. 195-93;
Arestis, Demetriades and Luintel, 2001, p. 20). A factor that in recent
times seems to have a possible strong impact on growth and development
of stock markets is the new information and communications technology
(ICT): mobile phones, personal computers and internet hosts. At the
theoretical level, some studies have presented arguments in favor of the
possible beneficial effects of information technology on an
economy's financial sector. For example, Levine (1997, p. 942-43)
notes that changes in telecommunications and computers, among other
factors, influence the quality of financial services and the structure
of the financial systems. In additions, the World Bank (1998, p.12)
notes that advancements in communication have for long been a major
driving force bringing about positive economic changes to many
countries. Further, the Human Development Report 2001 (UNDP, 2001,
chapters 2 and 3) gives a comprehensive account of how new technologies,
including information and communication technology, work for the
betterment of an economy. The rapid pace in dissemination of vast
amounts of vital information on the performance of stock and financial
markets is possibly contributing to the speed of the development of
stock markets.
However, at the empirical level, the literature is still rare
particularly in terms that support the theoretical contention as
indicated above. One reason for this rarity is the lack of long-term
time data series particularly on the modern instruments of ICT (mobile
phones, personal computers and Internet hosts) necessary to validate the
theoretical contention. While some data have recently been made
available on some of the modern instruments of ICT, an empirical
investigation into ICT and stock market relationships would perhaps be a
modest start to ascertain the impact of new information technology on
the growth of stock markets. Such useful attempts would also complement
the current discussions on information technology and its role in
spreading financial knowledge.
Thus, the primary aim of this paper is to examine the contribution
of ICT on stock market development in emerging markets and high-income
economies. To that end, in section two, we discuss some theoretical
arguments on information technology and stock market knowledge linkages.
A discussion of the estimation methodology, data and empirical findings
are presented in section three. A conclusion and policy implications are
provided in section four.
2. An Overview of ICT and Stock Market Developments
One of the support systems of a country's financial market is
the stock market. The stock market certainly is important to every
individual and firm and the economy in general. Research confirms that
countries with more developed financial institutions grow faster, and
countries with weak ones are likely to have financial crises, with
adverse effects on long-term growth and development. John Hicks (1969,
p. 36) argued that the financial system played a critical role in
boosting industrialization in England by facilitating the mobilization
of capital for immerse works. Several researchers have shown positive
evidence of finance-growth relationships. Among the notable works are
Goldsmith (1969, p. 1-12), Levine and Renelt, (1992, p. 960-63), Roubine
and Sala-I-Martin (1992, p. 5), King and Levine (1993, p. 538-40),
Easterly (1993, p. 187), Levine and Zervos (1996, p. 1-3), Levine (1997,
p. 723) and Ndikumana (2000, p. 381).
For long, stock markets were largely concentrated in high-income
countries. The transition towards the global economy saw many newer
economies developing their own stock markets and making them globally
competitive. Many countries around the world are now recognizing the
potential benefits of stock markets to their growth and development
process. In recent times, stock markets have emerged in some of the low
and middle-income economies.
Table 1 presents aggregate data on stock markets in a variety of
income categories. Between 1990 and 1999 stock markets grew rapidly in
low and high-income economies. For example, stock market capitalization
of listed companies as a share of gross domestic product (GDP) increased
from almost 10 to 32 in low-income countries and from 55 to 139 in
high-income countries. On the other hand, the number of listed domestic
companies showed tremendous increase in the lower-middle-income group of
countries during 1990-99 (Table 1).
Although several factors have been identified in previous studies
that contribute to stock market development, to the best of our
knowledge, no empirical study has attempted to investigate the
relationship between information technology and stock market
development. In a recent study Levine (1997, p. 725) concluded that the
financial system is shaped by non-financial developments. Changes in
telecommunications and computers, among other factors, influence the
quality of financial services and the structure of the financial systems
(Levine, 1997, p. 68890). In a similar vain, the World Bank (1998, p.16)
notes that advancements in communication have long been a major driving
force bringing about positive economic and social changes to many
countries.
Following past breakthroughs in communication modes, for example,
telephone, telegraph, radio, and television, such instruments have
brought profound changes to the conduct of business in many countries
globally. The continual advances in communication evident today, for
example, fully digitized wireless networks, are bringing about rapid
economic and social change in many countries. These new technologies are
contributing to the creation of global market place and are also
actively contributing to globalization. Many countries are also taking
advantage of such technologies and developing their own markets.
Although new technologies are being applied to several disciplines, for
example, education, environment, income generation and research and
development, the financial sector is the one growth area in many
countries that is making major use of new technologies in a vast range
of financial activities.
For example, with the growth in worldwide stock markets, many
people are getting educated about stock markets and are now investing in
stocks traded in a country's stock markets. Investors on the other
hand are in a dire need of information about companies, markets and
opportunities available to them. Newspapers have for long been the main
providers of stock market information. Given the rapid pace of
developments taking place in the business sector as well as the
increasing demand for vital information by financial markets
participants, this mode of communication may not suffice for information
hungry investors seeking stock market updates. Thus, the role of new
ICT: mobile phones, personal computers and the Internet provide easy and
cheap access to the daily performance of markets. New technologies have
a wider reach, are time saving and cost effective. For example,
inhabitants of remote areas typically lack information about current
stock markets or development of new ones. ICT is a powerful instrument
for remedying such information deficiencies.
Data on the distribution of worldwide information technology
instruments is presented in Table 2. The means of using information
technology in the new global economy are very unequally distributed as
revealed in Table 2. High-income economies are the dominant users of new
information technology. The average high-income economy has over 100
times more computers per capita than the average low-income country (The
World Bank, 1998, p. 27).
The world-wide information technology market--whose products
include personal computers and work stations, multi user computer
systems, data communications equipment and packaged software, grew by
about 12.2 percent a year in real terms between 1985 and 1995(The World
Bank, 1998, p. 57). Although the production of information technology
remains highly concentrated largely in OECD countries, the use of modern
communications media is expanding rapidly in other countries,
particularly in the lower and upper middle-income economies as shown in
Table 2. However, large gaps exist for line phones, mobile phones,
computers and Internet hosts between low and high-income countries.
Several factors contribute to these low numbers in low-income economies:
inadequate human capital, low purchasing power, and poor competition and
regulation. The number of cellular phones per fixed line in some low and
middle-income countries is already as high as in some industrial
countries, notable in Latin America and Africa. By the same token,
several developing countries in these regions with low density in both
traditional telephone service and cellular phones are now investing in
cellular technology at a very fast rate (UNDP 2001, Chapter 1).
3. Estimation Methodology, Data and Results
The theoretical arguments relating to ICT and stock market
development can be traced from economic growth literature emphasizing
the role of technology. Solow (1956, p. 65-70) clarifies the role of the
accumulation of physical capital and emphasizes the importance of
technological progress as the ultimate driving-force behind sustained
economic growth. Following several years of ongoing work within the
confinements of the Solow model, Mankiw, Romer and Weil (1992, p.
434-36) evaluate the empirical implications of the Solow model and note
that the fit could be improved by extending it to include human capital.
While the role of human capital has received extensive attention in
recent times. Recent contributions to the endogenous growth literature,
pioneered by Romer (1986, p. 1103 and 1994, p. 3-4) and Lucas (1988),
provide new ways of conceptualizing how human capital might contribute
to self-sustaining growth. The endogenous growth theory has certainly
reawakened interest in the role of human capital providing ample
evidence that technology and human capital play an essential role in a
country's development (Barro, 1991, p. 438-41).
Because several factors contribute to higher levels of human
capital, this aspect is of prime importance. For example, the new-growth
theory gives significant weight to human capital--creating agents who
can become more productive through their acquisition of knowledge and
increased skills. In this study, we hypothesize that ICT technology
plays a vital role in enhancing financial and economic knowledge for
participants who deal with stock market as well as other markets. As
with human capital, technology including the new ICT is equally
important in nation building. The new-growth theory explains that
technical progress is determined by the "accumulation of knowledge
by forward-looking profit maximizing agents" (Romer, 1986).
Technological progress is considered to generate productivity gains, as
is an component behind sustained economic growth.
Although a country's level of achievement and development in
technology can be a result of advancements in several physical and
natural disciplines, the focus is narrowed to developments in
information technology and its vital role in accelerating the
dissemination of essential knowledge. Such knowledge may include
financial and stock market movements and developments, among others.
Communication instruments like newspapers, televisions and line phones
can play a vital role in improving financial markets in many countries
aiming to improve and achieve a higher level of development of stock
markets through transfer of essential financial information and
knowledge. The World Bank (1998, p.6) and UNDP (2001, p. 5-12) note that
advances in communication technology (referring largely to old
technology) have for too long been a major driving-force in bringing
about positive economic change in many countries. Developments including
line telephones, telegraph and radio and today's advancements in
wireless, fully digitized networks are likely to bring about profound
economic and financial changes in many countries.
The hypothesis concerning advances in digital information
technology, that is, mobile phones, personal computers and access to
internet, is that it allows the processing, dissemination and storage of
vast amounts of information together with fast, effective and cheap
distribution systems such as cellular telephones, personal computers and
Internet hosts. Thus digital communication networks are likely to have a
favorable impact on the economic and financial markets of many nations:
the creation of new opportunities for individuals to improve participate
in share markets, expand knowledge, speed business transactions and
enhances the development of the financial sector. This is achieved
through the use of cellular telephones, personal computers and Internet
hosts provide easy and cheap access to information, information dealing
with economic fundamentals and financial markets development. These
technologies have wide implications, are timesaving and cost-effective
as can be seen in Internet usage and in the ability of the World Wide
Web to deliver vital information to the poor at any locality, globally.
Our estimation procedure begins with a primary model that takes the
following general form:
[SMD.sub.it] [[PI].sub.0] + [[PI].sub.1] [X.sub.it] [[mu].sub.it]
(1)
Where, SMD is stock market development; X is a vector of stock
market control variables; Y is a vector of ICT variables; i is the
country identifier; and t is the time identifier. The error term follows
the classical assumptions, expressed as
E([[mu].sub.it]) ~ N(0, [[sigma].sup.2])
The variables that contribute to the primary model in equation (1)
is described by equation (2).
[vst.sub.it] = [[alpha].sub.0] + [[alpha].sub.1] [mc.sub.it] +
[[alpha].sub.2] [cps.sub.it] + [[alpha].sub.3][tml.sub.it] +
[[alpha].sub.4][tv.sub.it] + [[alpha].sub.5][mp.sub.it] +
[[alpha].sub.6][pc.sub.it] + [[alpha].sub.7][inet.sub.it] +
[[mu].sub.it] (2)
where,
vst = total value of stock traded as percent of gross domestic
product (GDP)
mc = market capitalization of listed domestic companies as a
percent of GDP. We define stock market capitalization as the sum of the
market capitalization of all firms on domestic stock exchanges, where
each firm's market capitalization is its share price at the end of
each year times the number of shares outstanding.
cps = credit to the private sector as a percent of GDP
tml = all telephone main lines that connect a customer's
equipment to the public switched telephone network, per thousand people.
mp = mobile phones, referring users of portable telephones
subscribing to an automatic public mobile telephone service using
cellular technology that provides access to the public switched
telephone network, per thousand people.
pc = personal computers. This is the estimated number of
self-contained computers designed to be used by a single person, per
thousand people.
in = Internet. This is the number of computers directly connected
to the worldwide network of interconnected computer systems, per
thousand people.
For our analysis, we chose a sample of economies from emerging
markets and the high-income category based on data availability. The
sample of emerging market economies include: Argentina, Brazil, Chile,
China, Colombia, Egypt, Hong Kong, India, Indonesia, Israel, Malaysia,
Mexico, Peru, Philippines, Poland, Russia, Singapore, South Africa,
Thailand, Turkey, and Venezuela. The sample of high-income economies
include Australia, Austria, Belgium, Canada, Denmark, Finland, France,
Germany, Greece, Ireland, Italy, Japan, Netherlands, Norway, Portugal,
Spain, Sweden, Switzerland, United Kingdom, and United States of
America. The data source for all dependent and independent variables is
World Bank's World Development Indicators CD-ROM (2001).
Due to the unavailability of long-term data series on some of the
explanatory variables (mobile phones, personal computers and Internet
hosts), we adopted the common practice of pooling data for our chosen
sample countries. Since the data relates to countries over time, there
is bound to be heterogeneity in these sets. By combining time-series of
cross-section observations, panel data give more information data, more
variability, less collinearity among variables, more degrees of freedom
and more efficiency.
Based on equation (2), Table 3 presents the ordinary least squares
(OLS) estimates for the primary model. The reported results show that
the two stock market control variables carry the expected signs and are
statistically insignificant. Variables, pc and inet has the desired
positive effect but statistically insignificant. Variable mp has a
negative sign (opposite to the expected effect) indicating that it is
not a major factor contributing to stock market development.
The primary model estimated is considered to be simple as it
disregards the cross-sections and time dimensions. It is quite likely
that because of its simplicity, the true picture may be distorted.
Therefore, what is needed is to find a way to account for the specific
nature of different cross-sectional units among the countries in our
sample. Thus, we adopt the least squares dummy variable regression
(LSDV) model, also known as the fixed effects model (see for example,
Greene, 2000, p. 560). The assumption here is that there are differences
among the cross-sectional units, that is, our selected sample of
countries differ amongst each other. The LSDV model takes into account
the individuality of each country. As such we introduce two separate
dummy variables, dum1 and dum2. The hypothesis behind dum1 is that
countries in high-income category have an added advantage in stock
market development because of income differences. This matters more to
high-income countries than to emerging market economies, which are
largely, middle income categories secondly, we include dum2 to take into
account of technological advancements. Technologically advanced
countries have an edge in terms of ICT and stock market development than
those that are not. We consider the following countries to be more
technologically advanced: Australia, Austria, Belgium, Canada, Finland,
France, Germany, Ireland, Japan, Netherlands, Norway, United Kingdom and
United States of America. Thus, equation (3) represents the LSDV models.
[vst.sub.it] = [[delta].sub.1][mc.sub.it] +
[[delta].sub.2][cps.sub.it] + [[delta].sub.3][dum1.sub.it] +
[[delta].sub.4][dum2.sub.it] + [[delta].sub.5][tml.sub.it] +
[[delta].sub.6][tv.sub.it] + [[delta].sub.7][mp.sub.it] +
[[delta].sub.8][pc.sub.it] + [[delta].sub.9][inet.sub.it] +
[[mu].sub.it] (3)
We conduct a formal test of the primary and the LSDV model using
the restricted F test as follows
F = [R.sup.2.sub.UR] - [R.sup.2.sub.R]/m/(1 - [R.sup.2.sub.UR])/(n
- k) (4)
where [R.sup.2.sub.UR] and [R.sup.2.sub.R] are, respectively, the R
square values obtained from the unrestricted and restricted regressions.
It should be noted that
[R.sup.2.sub.UR] > [R.sup.2.sub.R] and
[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]
On the basis of equation (4), the F-value is 9.4, statistically
significant and therefore the restricted regression involving model
(equation 2) seems to be invalid.
Table 3 shows the empirical results of the LSDV model considered to
be more robust than the primary model. The stock market control
variables, mc and cps carry the expected signs and reveal statistically
significant effects on stock market development. The explanatory power
improves compared to the primary model. The results of the stock market
control and the ICT variables explain their contribution to stock market
development. The statistical significance of variable cps, pc and inet
improve too. While mc and cps have produced the desired effect, they are
also statistically highly significant. In general, the results of the
stock market control variables suggest their importance in the
development of stock market suggesting that market capitalization and
credit to the private sector are important in the growth and expansion
of stock markets.
Turning to the ICT variables, mp, pc and inet show consistent
patterns in their coefficient signs from the primary model. The
coefficient mp has a negative sign in both cases, contrary to our
theoretical exceptions. The result of this variable is not surprising as
mobile phones have a low diffusion rate largely in the emerging market
economies. On the other hand, pc and inet have the excepted positive
effect of stock market development and both are statistically
significant.
Our LSDV model is more relevant here as we control for the
cross-sectional effects in two ways: the income and technological
differences. Variable dum1 taking into account of the income differences
did not reveal any positive effect, thus, the results of this variable
indicated that country differences on the basis of income levels are not
a significant factor in terms of stock market development. When
technological achievement is controlled by variable dum2, it also did
not reveal any positive effect.
To provide some additional support to primary and the LSDV models,
we also adopt a third estimation procedure; the panel corrected standard
errors (PCSE). Equation (2) was reestimated using the PCSE procedure.
For example, it has been noted that in cross-country comparison, there
may be a variation in the scales of the variables in the model with
expected cross-section heteroskedastic -consistent covariance matrix of
pooled regression models where the covariance matrix estimates gives the
PCSE. The PCSE are obtained as the square roots of the diagonal matrix as follows:
cov(b) = [(X' X).sup.-1] [(X'([PHI] [cross products]
[I.sub.T]X) [(X' X).sup.1]
where [PHI] is an N x N matrix with the (i,j)th element estimated
by:
[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]
Results obtained for the PCSE model are reported in Table 3. The
expected effects are same as the LSDV model as discussed above.
Comparing the results of PSCE with the LSDV model, the LSDV model is
more robust.
The results revealed by the sample of high-income and emerging
market economies are quite unique. Theoretically, one would expect
high-income economies to be leaders of dominant in terms of stock market
development given their high-income levels and infrastructural
development in communications technology and industry. Our findings show
this aspect is not so important as emerging market economies with lower
levels of income and technological capacity are quickly seizing an
opportunity to leap frog the industrial or high-income countries, that
is, by going straight from underdeveloped networks to fully digitized
networks, bypassing the traditional analog technology that still forms
the backbone of the system in most industrialized countries. In fact in
1993 some two dozen or more developing countries already had fully
digitized networks, while the level of digitization in the OECD
countries averaged just 65 percent (The World Bank, 1998, p. 57).
We also noted in section two (see Table 1), that the upper
middle-income economies have experienced rapid growth in stock markets.
Our sample also revealed that several economies in the emerging market
category also fell in the upper middle-income category. Therefore, the
high level use of new information technology and rapid growth in stock
markets side by side adds more sense to the strength of the results
obtained.
Further, our results certainly support the views expressed by
Levine (1997, p. 723-25). Levine (1997, p. 688-89) argued that the
finance-growth link goes beyond the relationship between finance and
shorter-term fluctuations. He further notes that a financial system is
shaped by non-financial developments. Among other factors, changes in
telecommunications and the number of computers influence the quality of
financial services and the structure of financial systems. Our results
obtained here certainly provide additional support for Levine's
(1997, p. 688-89) arguments that are discussed above.
The results of our information technology measures, in particular,
personal computers and internet, are no doubt a part of the
non-financial sector that has a positive influence on growth and
development of the financial sector. This is allowing some emerging
markets to leapfrog their counterparts in high-income countries. Such
evidence is supported by the phenomenal increase in the magnitude of
equity flows in Asia (for example, China) and Latin America (for
example, Mexico). Information technology does certainly assist in the
flow of capital across borders. Private capital outflows are important
for emerging market economies and their importance continues to increase
over time, particularly in two of the emerging regions--Asia and Latin
America. International portfolios in these markets are more concentrated
in equities than in bonds. However, these regions have experienced
significant increases in portfolio investments (bonds and equity). The
relative importance of mutual funds has also grown substantially.
Emerging markets in Asia that capture large share of mutual funds are
Hong Kong, Korea, Taiwan and Malaysia while in Latin America, its Brazil
and Mexico. Kaminsky, Lyons, and Schmukler (2001, p. 25-36) note that in
absolute values, bond and equity flows since 1994 in Latin America.
These authors further note that overall bond and equity flows to Latin
America declined between 1996 and 1998 from about $44 billion to about
$15 billion and bond and equity flows to Asia collapsed in 1998 to $9
billion from their peak in 1996 if #38 billion. In general, equity
investment in emerging markets has grown rapidly in the 1990s with large
proportion of equity flows channeled through mutual funds. Mutual funds
hold a sizeable share of market capitalization in emerging countries.
These funds in general have been experiencing rapid growth. Asian and
Latin American funds achieved the fastest growth but their size remain
small compared to domestic US international funds.
It is also worthy to note in regard to financial market
developments that over the past decade some developments in
international finance have been crucial particularly in China. Of
foremost importance is its dominant positioning receiving foreign direct
investment (FDI) in the world. According to UNCTAD (1998, p. 10-12),
accumulated FDI flows into China during 1992-97 were $196 billion,
constituting over 30% of total FDI into all developing countries closely
allied to the developments and progress in FDI flows, China in recent
times have also experienced phenomenal growths in its equities market.
Several factors seem to have contributed to this development. For
example, in regard to FDI boom, Zhang (2001, p. 336-38) notes that
China's liberalization of investment regime (for example, the
promulgation of Sino-Foreign Joint Venture Law), explosive growth of the
domestic economy and a stable political environment have all contributed
to its phenomenal growth in FDI inflows. These developments are also
likely to have significant spillover effects as evidenced by the case of
China.
4. Conclusion and Policy Implications
Using panel data from high-income and emerging market economies,
this paper carries out an empirical investigation of the links between
new information technology and stock market development in emerging and
high-income economies. Three different estimation procedures: a primary
OLS model n LSDV and a PSCE are adopted. The LSDV model produced the
most robust results. Based on this, personal computers and Internet
hosts are the two ICT variables that showed strong positive influence on
stock market development in our sample countries. The results also
revealed strong positive effects of market capitalization and credit to
private sector as a non-ICT contributor to stock market development.
Mobile phones did not show any positive effect. Controlling for income
and technological achievements, our results lead us to conclude that the
emerging market economies have already seized in an opportunity to leap
frog the industrial or high-income countries, that is, by going straight
from underdeveloped networks to fully digitized networks. Such a move is
having a tremendous positive effect on the financial sector of emerging
market economies. Our results also support some policy implications
particularly to the lesser-developed economies.
Financial systems are shaped indeed by non-financial developments.
Recent advancements in telecommunications, computers, electronic
communications, among other factors, are catalyst for stock market
development in emerging economies. Such developments are likely to add
further impetus to the growth and devilment of many emerging market
economies.opportunities are also great for many low and middle -income
countries to take advantage for the new information and communications
technologies in disseminating financial knowledge and expanding their
stock markets thus enhancing their financial growth and development
process.
The main policy implication for the lesser developed countries and
those with low levels of ICT diffusion is to act quickly to seize the
opportunity for information technology development by investing in the
physical as well as human capital infrastructure of a modern and perhaps
fully digitized communication networks. Such a move will certainly have
a favorable effect not only on promotion and development of stock
markets but also on overall economic growth.
Secondly, maintaining a robust economic environment is essential,
not only to promote stock market development but to create opportunities
for useful ICT innovations to be created and diffused. Growth and market
conditions leased to technology creation, which attracts domestic and
global corporations and enhances the growth and development of stock
markets. Therefore, greater ICT diffusion as well as stock market
development would require flexible, competitive and dynamic economic
environments. The implications for countries who are lagging behind in
terms of their stock market growth is to implement policy reforms that
emphasize openness to new investors, ideas, and products especially in
communications an information technology areas. Adherence to closed
market policies towards ICT and stock market development while promoting
policies that favor government monopolies will surely isolate countries
from foreign capital as well as global ICT networks.
Although the benefits of information technology for stock market
development are still in infancy in many lesser-developed economies,
tremendous potentials lie ahead. These will directly assist in extending
beneficial spillover effects in other areas of financial markets, for
example, banking, trade and foreign exchange. We conclude that
increasing the level of ICT diffusion is essential for productivity
gains and improvements economic performance in emerging
economies/markets. From a global business perspective high level of ICT
diffusion capability is indicative of its level of ICT infrastructural
development. This in turn serves as a positive signal to domestic and
foreign investors seeking to expand globally.
