LITERATURE REVIEW AND RATIONALE FOR SAFTA 27<br />

The lack of trade complementarity in bilateral trade<br />

flow and the similarity of the pattern of comparative<br />

advantage in the region have been identified as some<br />

of the main constraints for the growth of intra-regional<br />

trade (Kemal et al. 2000).<br />

Daniel (2007) evaluates the SAFTA within the<br />

global structure of overlapping RTAs using modified<br />

gravity equation. First, it examines the effects of the<br />

Trade Liberalisation Program (TLP) which started in<br />

2006. SAFTA would have a minor effect on regional<br />

trade flows and the impact on custom duties would be<br />

a manageable fiscal shock for most members.<br />

However, there exist studies that argue in favour<br />

of SAFTA. Raihan and Razzaque (2007) using CGE<br />

modeling estimate the trade creation and trade diversion<br />

effects of SAFTA. They show that a full implementation<br />

of SAFTA will lead to welfare gains for India, Sri Lanka<br />

and rest of South Asian countries, though Bangladesh<br />

suffers from welfare loss. Bangladesh’s welfare loss is<br />

mainly driven by the negative trade diversion effect.<br />

Simulation results also suggest that the negative trade<br />

diversion effect can be undermined by some associated<br />

unilateral trade liberalisation measure. It is also<br />

important to note that trade diversion for Bangladesh<br />

and possibly for other LDCs under SAFTA is inevitable.<br />

Bangladesh and other LDCs in South Asia will have to<br />

raise their export share into the Indian market<br />

substantially in order to increase welfare through positive<br />

terms of trade effect. Export diversification in this<br />

regard is very important.<br />

World Bank Study (1997) analyses the static welfare<br />

consequences of preferential liberalisation. Using an<br />

integrated general equilibrium model of the world<br />

economy (Global Trade Analysis Project, GTAP) it<br />

shows that regional trade liberalisation would increase<br />

the welfare between 0.5% of GDP for India and one<br />

percent for the rest of South Asia. The welfare gains<br />

from regional liberalisation are the sum of trade<br />

creation effects (increased trade between countries in<br />

the region) from lower barriers minus trade diversion<br />

losses caused by replacing non-South Asian imports<br />

with now preferred South Asian goods plus the terms<br />

of trade gains associated with increased access to each<br />

other’s still protected markets. The benefits to the rest<br />

of South Asia are larger than to India because the former<br />

gains free access to many highly protected markets of<br />

latter which results in a significant improvement in<br />

terms of trade. The study does not, however, estimates<br />

individual country impacts except for India<br />

RIS (2004) reports the result of studies conducted<br />

in the framework of gravity model. It suggests that<br />

complete elimination of tariffs under SAFTA may<br />

increase the intra-regional trade 1.6 times. It further<br />

suggests that in the dynamic framework the gains from<br />

liberalisation are at least 25% higher than the static<br />

gains.<br />

Kumar and Saini (2007) estimate different scenarios<br />

for SAFTA and its implications welfare on each country.<br />

They find that a South Asian Free Trade Area, as<br />

envisaged under the SAFTA scenario, does not result<br />

in welfare gains for all the member countries. SAFTA<br />

results in small welfare gains for all the South Asian<br />

countries except Bangladesh. Rest of South Asia (RSA)<br />

gains most by about half a billion dollars, while India<br />

gains by about US $204 millions and Sri Lanka by just<br />

US$89 millions only. Bangladesh on the other hand<br />

suffers welfare loss of about US$225 millions. The gains<br />

in welfare for RSA, India and Sri Lanka are basically<br />

due to gains in terms of trade, and to a lesser extent<br />

from improvements in allocative efficiency in the case<br />

of RSA and Sri Lanka. Bangladesh loses out both in<br />

terms of allocation efficiency and terms of trade by<br />

US$104 and US$106 millions, respectively.<br />

In sum, there exists a debate in the literature on<br />

the possible gains of SAFTA. Studies using different<br />

methodologies arrive at different results. Most of the<br />

studies have examined the impact of lowering tariffs<br />

to zero under SAFTA though few studies have also<br />

examined the impacts under alternative scenarios. The<br />

main objective of this study is to give a holistic picture<br />

of the effects of SAFTA on trade, inward investments<br />

and welfare aspects. More importantly, the study has<br />

focused on the potential of trade in services in the region<br />

and explored the ways of harmonising the regulations<br />

existing in different modes of trade in the identified<br />

services sectors. Possibilities of arriving at MRAs in<br />

different services sectors are delved on.<br />

In arriving at the conclusions on impacts of SAFTA,<br />

the study adds to the existing literature in three<br />

important ways. First, it estimates the change in the<br />

extent of complementarity and competitiveness at SITC<br />

five-digit level of the South Asian region for the years<br />

1991 and 2004 to assess the change in the composition<br />

of competitiveness basket as well as their complementarities.<br />

The change in the complementarity and competitive<br />

baskets overtime to a large extent is able to resolve<br />

the differences arrived at by the studies estimating the<br />

impact of SAFTA using pre and post 2000 trade data.<br />

The impact on each country’s trade and welfare is<br />

analysed using CGE modeling which is followed by<br />

the estimates of trade creation and trade diversion<br />

following SAFTA using the gravity model. The study
