CALL ME MAYBE: THE IMPACT
OF TELECOMMUNICATIONS
ON ECONOMIC GROWTH IN
THE ASEAN REGION
DLSU - SOE
MCREY BANDERLIPE II, MSc (CPA)
Introduction



Communication plays a very important role for
everyone. We cannot live without communicating
with one another.
The advent of new modes and technologies in
communications resulted to real-time transfer of
information to make relevant decision.
Economic activities are also affected by the ingress
of telecommunications.
Introduction

Increased realization of benefits of new
technologies in information and communications is
one of the targets towards attaining the UN
Millennium Development Goals due on 2015.
 Increased
telendensity of fixed line telephones
 Increased teledensity of mobile cellular phone
subscriptions
 Increased Internet users.
Introduction
Goals and Targets
(from the Millennium Declaration)
Indicators for Monitoring
Progress
Goal 8: Develop a global partnership for development
Target 8.F: In cooperation with the private sector,
make available the benefits of new technologies,
especially information and communications
1. Fixed telephone lines per 100
inhabitants
2. Mobile cellular subscriptions
per 100 inhabitants
3. Internet users per 100
inhabitants
Introduction


We focus our attention on ASEAN region.
Go Chok Tong (2003) iterated the need to redirect
the future of ICT
 To
promote economic recovery
 Job creation
 Sustained economic growth
 Bring more economies closer
Statement of the Problem
The need to embrace technology would support
continuous improvement in terms of productivity,
efficiency, competitiveness, and the quality of the lives
of people, for these are the true benefits of a
connected ASEAN Region. Thus, in this study, we seek
to answer this question:
Does teledensity/penetration rate of mobile and
fixed telecommunications affect economic growth
among countries in the ASEAN region?
Literature Review



Origin: Solow (1956) paper on neoclassical growth
theory, explained through labor, capital, and
knowledge (technological progress)
Convergence Theory and the Possible Sources of
Growth (Barro and Sala-I-Martin, 1992; Datta and
Agarwal, 2004; Chakraborty and Nandi, 2011)
Liberalization of trade and services towards
export-led growth, allocative efficiency and
technology transfer (Snow, 1989)
Literature Review



Landmark Paper: Roller and Waverman (2001)
Micro modelling with Macro Production Function
approach
Succeeding studies found association of
telecommunications and econ growth. (e.g.,
Waverman, Meschi, and Fuss (2005), Negash and
Patala (2006), Melamed (2007), Shiu and Lam
(2008), Sridhar and Sridhar (2009), Lam and Shiu
(2010), Biancini (2011), and Grouber and
Koutrompis (2011), among others).
Literature Review

Development initiatives in the ASEAN region
 1997:
ASEAN Vision 2020
 1998: Hanoi Plan of Action

ASEAN’s thrust
 Provision
of reliable ICT infrastructure
 Literacy and comfort in using ICT services
 Harmonize regulations in the telecom industry
 Linkages outside the region
 Embrace technology for improvement
 Protection from intentional harm and degradation
Note. Data obtained from the World Bank database (data.worldbank.org)
Note. Data obtained from the World Bank database (data.worldbank.org)
Framework of the Study

Growth (Solow, 1956)
 Knowledge
comes in many forms
 Knowledge accumulation is understood to contribute to
economic growth (Romer, 2006).

Network Externalities and Spillover Effects
 Telecommunications
create information superhighway
 Growth in the number of users increases the derived
utility from such use of infrastructure
 Low costs of doing business, benefiting businesses,
increasing productivity and growth.
Framework of the Study

Transaction Costs and Spillover Effects
 Reduced
transaction costs of acquiring and transmitting
information
 More efficient production mechanism that supports
growth.

Social Overhead Capital
 Expenditures
on economic and social services.
 Establishment of the New Economy with better
competition and enhanced production processes.
Working Model
ln GDPPCit  1  2 ln GNEPCit  3 LFPRit  4 PENRit  5ti   it
Where:
ln GDPPCit = ln of real GDP per capita (constant 2000 US$) of country i
at year t;
ln GNEPCit = proxy for expenditure (ln of gross national expenditure per
capita at constant 2000 US$) for country i at year t;
LFPRit
= labor force participation rate of country i at year t;
PENRit
= teledensity or penetration rate for country i at year t, and
= a variable that captures the essence of time trend for
ti
country i (1 = 1992, 2 = 1993,…, 19 = 2010).
Methodology

Balanced Panel Data Analysis of 7 ASEAN Countries
 (Brunei
Darussalam, Indonesia, Malaysia, Philippines,
Singapore, Thailand, Vietnam; indexed in order)
 Relevant data were obtained from 1992 – 2010.

Data Source
 World
Bank database (data.worldbank.org)
 Teledensity (No. of subscribers for every 100 inhabitants)
 Penetration Rate (Teledensity / 100) for fixed line
(FLPENR), mobile (CPPENR) and total penetration rate
(TPENR)
Results

Naïve Model
 lnGNEPC
and LFPR are identified to be significant at α
= 0.001
 High R-squared for all regressions
 Failure to account for unobserved heterogeneity makes
this model not suitable.
 This model failed the tests for plausibility and
robustness of econometric models.
