Exports on Economic Growth: The Case of Selected Southeast Asia Countries ABSTRACT The thesis aims to answer the question that how is exports affect on the economic growth in the five selected Southeast Asia countries, including Indonesia, Malaysia, Singapore, Thailand and Vietnam, during the period of 1991-2010 by using the neoclassical growth model established by Romer (1986) and Lucas (1988) In the period of 1991-2010, economic growth of the five Southeast Asia countries were growing very fast in tandem with the strong growth of exports This is because the economies of the five Southeast Asia countries largely relied on trade activities, especially exports, with developed countries such as USA, Japan, and European countries, etc… Therefore, determining and examining the impact of exports on economic growth are important to help these countries keep their growth sustainable In this paper, the augmented Solow Growth Model was adopted to find the impact of exports on growth Also, the key model employed to run regression is Linear Exports-Growth Model with a panel data of the five Southeast Asia countries To capture the different impact of exports on growth over the selected countries, fixed effect regression model is chosen to apply in the paper The main findings of the paper point out that only Malaysia, Singapore and Thailand of which exports have statistically significant positive impacts on economic growth at the levels of significance of 1%, 1% and 10%, respectively Oppositely, Indonesia and Vietnam showed a negative impact on economic growth, however, these impacts were not statistically significant In addition, to measure and compare the different impacts of exports on growth over the selected countries, the fixed effect regression model is employed The results showed that the more developed the economy is, the stronger impact of exports on economic growth is More specifically, the impact levels of exports on growth at the five selected Southeast Asia countries are ascendingly arranged based on development of the economy as follows: Vietnam (-0.029%), Indonesia (-0.016%), Thailand (0.151%), Malaysia (0.196%) and Singapore (0.495%) Chapter INTRODUCTION 1.1 PROBLEM STATEMENT Economic growth is often the final goal of the economy To accelerate economic growth, it is vital to know where sources of economic growth come from and this is subject of controversy amongst economists One side, economists such as Solow (1957), Romer (1986), and Lucas (1988) reckoned that TFP laying residual brings about growth in long term Romer (1986) emphasized research and development while Lucas (1988) stressed on role of human capital formulation as significant cause of growth Trade far ago was an effective way that human being used to exchange products they had and received other essential products that they were unable to produce to meet their daily life Trade at that time played a vital role as a blood vent in a human body and was the best way that human being had in daily life, production activities and social development Nowadays, the importance role of trade in modern society and economy is significantly increasing, especially exports Exports have helped many countries reach impressive economic growths and become very rich and powerful countries such as Japan, China, Korea and Taiwan, etc From the origin of theories of reputable economists with classical school thoughts in hundreds of years ago such as: Adam Smith (1776) and David Ricardo (1817), and being connected recently by a series of theoretical works of other well-known economists Misselden (1623) Chapter CONCLUSIONS, POLICY RECOMMENDATIONS AND LIMITATIONS 6.1 CONCLUSION This paper aims to examine the hypothesis if exports will increase economic growth and it also makes clear how different will exports affect on economic growth over the selected Southeast Asia countries It complements the previous literature by focusing on exports and by considering a more representative sample of variety of economies in Southeast Asia From the result of descriptive statistics and regression methods, this paper has examined and measured the impact of exports on economic growth using the Fixed Effects approach with a pooled data set of the five Southeast Asia countries including Indonesia, Malaysia, Singapore, Thailand and Vietnam By using descriptive statistics and regression analysis method, the paper found out that exports have unequal impacts on the five Southeast Asia countries’ economic growth More specifically, there are obviously two groups of countries that the impact of exports is oppositely different: Group comprises of three countries: Malaysia, Singapore and Thailand of which economies are more developed than the two remaining countries Group contains the two Indonesia and Vietnam of which economies are less developed In Group 1, export growth is statistically significant and has positive impact on these countries’ economies The paper concludes that export growth and capital growth are two important factors on long term positively impacting on the development of these countries’ economies Besides, labor growth 59 is also to have positive contribution on Singapore’s economic growth, but has no impact on Malaysia and Thailand This result is considered as quite reasonable with the current development of the three countries’ economies In that, Singapore with a very highly developed economy largely depends on export activities of capital-intensive and high value added products Additionally, Singapore’s economy shows that it is very sensitive to labor growth and labor growth brings a very good growth for its economy by 0.476% for each percent of growth in labor force This is thanks to Singapore’s good policy in training labor as well as attracting qualified labor that help it have high skilled labor and bring positive growth for the economy However, capital growth causes an unremarkable contribution to this economy This proves that Singapore’s economy is becoming less efficient in investing capital that has led to a wave of investing capital to foreign countries because of higher efficiency Malaysia and Thailand have also achieved a relatively developed economy by focusing on export-oriented policies and capital to invest in major industries for export, for example IT industry with Malaysia and automobile industry with Thailand In contrast, the result for Group shows that exports are both statistically insignificant and bring negative sign In the two countries of this group, unexpectedly export growth has no meaning in their economic growth In term of impact of other variables, capital growth of Indonesia has better contribution to economic growth than Vietnam More particularly, except exports capital growth have statistical meaning and positive impact on Indonesia’s economic growth, especially the strong contribution of capital growth at 0.402% growth for percent growth of capital This evidences that Indonesia is efficient in attracting and using capital for economic development The most special case is Vietnam with all variables bringing negative values and being insignificant that show that capital, export and labor growth has no meaning in Vietnam’s economic growth in all 60 6.2 POLICY RECOMMENDATIONS 6.2.1 For The Selected Southeast Asia Countries The study result has pointed out that in the five studied countries; exports show its importance and positive impact of on economic growth at countries of which economies are more developed including Malaysia, Singapore and Thailand This is thanks to good policies and appropriate supports from these countries’ government for export industries They have specialized and focussed on key export industries that bring high value added products, for example ship building, electronic goods, sea port services for Singapore, IT for Malaysia and automobile making for Thailand They have selectively invested in high-tech production and modern technologies At the same time, they have built up a good and perfect infrastructure to support export industries They have also led their economies to be export-oriented for many years ago Thus, to continue having good economic growth, these countries should continue promoting and supporting exports, continue purchasing policies to keep an export-oriented economy They should keep their trade surplus achievements and always be the pioneer in technology and technology innovation They also need subsidy policies for export enterprises to find new markets, partners and expand market for export With the two remaining countries including Indonesia and Vietnam of which economies are less developed than the above counties, exports have no meaning on economic growth and exports not yet play obvious important role in these countries economies This is due to trade deficit, behind-time technology, weak competitive ability, inefficient and expansive investment and low value-added products Therefore, a policy to encourage exports and lead the economy growing under export-oriented base is recommended This proper policy will help increase international trade surplus, increase export value and national accumulation As a result, export growth will have a positive impact on economic growth and will be a good basement for an economy to grow For example, a country with an export surplus will help increase its national resource accumulation to produce more goods and services and make the economy grows 61 6.2.2 For The Case of Vietnam In particular, for the case of Vietnam, Vietnam’s economy is still developing and the export industry is quite weak Exports still have no impact on economic growth This is due to many reasons: Firstly, Vietnam export products mainly are mainly raw, agricultural products and natural resources; Vietnam also does not have high value-added or high-tech products Typically, Vietnam only exports raw products with low value added for example non-processed agricultural products and crude, non-refined oil This makes exports not bring high value surplus to Vietnam’s economic growth Meanwhile, Vietnam imports processed agricultural products and refined oil from foreign countries with a very high cost As such, it is a bitter fact that Vietnam is selling its natural resources with low price and buying those products back with high price As a result, it will lead to trade deficit and make Vietnam exports have no positive impact on growth Secondly, technique and technology of Vietnamese export enterprises are weak, old and mostly are backward technologies This leads to low value of export product and low comparative ability of Vietnam export enterprises One more reason is that Vietnam lacks of key products with its own well-known brand-name and high-tech products for export Typically, in garment and IT industries, Vietnam has no its own well-known brand-names for export and almost focuses on processing products for other countries to be paid a very low processing cost While processed products from Vietnam will be brought brand-names of other countries and sold at a very high price of which gainers are other countries Therefore, in order to help make Vietnam become a country with a developed economy as Malaysia, Singapore and Thailand, it should have economic policies focusing on the following determinants: Policies to lead the economy becoming an export-oriented economy are very necessary for Vietnam Encourage and promote exports should be made with products and industries that have high comparative advantage for export Besides, it is an effective way to utilize all 62 resources for developing industries and fields bringing high value-added and high comparative advantage products for export Policies to limit and stop trade deficit by imposing high tax barriers to import products that Vietnam can produce or luxurious products This will benefit the economy trade surplus and make exports positively contribute to economic growth Policies should also have subsidies or supports to encourage export enterprises to find as many trading partners as possible, this will help expand and develop new markets In term of destination, policies should encourage to find new market out of traditional Asia market to diversify "destination" and avoid or reduce locally risks because export is the most important foreign exchange source in supporting import for domestic production The government can this by providing domestic and international market information for entrepreneurs to reduce problems of asymmetric information (this is considered as new failure of market that the government must play a considerable role in solving this problem (Stiglitz, 2002) and stepping up commercial promotion Besides, the government can support domestic entrepreneurs by building good soft and hard infrastructures to reduce costs and time to enter and exit market as well as costs and time of production At the same time, it is very necessary to build high-tech industry zones to specialize in manufacturing products for export Technology innovation and improvement are very necessary to the economy to help enterprises improve competiveness and product quality for export Building and supporting processing industries will help to create more value-added for export products Avoiding and minimizing to export rude goods with low value and non-processed natural resources will make economic growth more sustainable and balanced One more factor is capital, a very important factor for growth So, it is necessary for growth to attract investment capital However, it is evidenced that capital from national saving and internal sources is safer for economic growth than external debt Government expenditure and private investment are determinants for growth As a result, Vietnam should make investment environment better by infrastructure improvement, simplifying administrative bureaucracies and formations At the same time, Vietnam should have more preferential tax policies and 63 subsidies to encourage domestic investment Controlling well and tightly investment capital is very vital to help using capital efficiently and avoid waste and loss of capital by corruption and bribe Finally, quality of labor force is very important Vietnam should have more supports for training and enhance in both quantity and quality of labor force In addition, Government should also have proper policies of vocational education and training focusing on key high technical and technological industries for exports This will help and benefit Vietnam to have a skilled and talented manpower to develop and get sustainable growth 6.3 LIMITATIONS OF THE THESIS There is a limitation that the paper have not obtained regarding the second objective: comparison of the impact of exports on growth crosss the selected countries That is because both export growth and labor growth of Indonesia and Vietnam are insignificant and have no statiscal meaning, therefore the measure impact of these countries met difficulty and the comparison cross the selected countries are limited Not enough data for Vietnam has made the study choose the panel data of five ASEAN countries including Indonesia, Malaysia, Singapore, Thailand and Vietnam in order to reach a more reliable outcome It is expected to conduct a study on impact of exports on economic growth only for the case of Vietnam later At the same time, the causal relationship between exports and growth and thresholds effect between exports and growth are also recommended for the future studies 64 REFERENCES Aghion, D., and Howitt, P 1992 A Model of Growth through Creative Destruction
