CHAPTER I: INTRODUCTION 1.1 Problem statement There are many debates about the sources of economic growth from supply side and demand side On the supply side, economic growth can be explained by the consolidation of factors such as inputs, productivities, research and technology Krugman (1989) believes that each country has its own growth rate because of different growth of total factor productivity Solow (1957) states that total factor productivity in the Solow residual brings growth rate in the long term On the demand-led growth, Keynesian (1936) considers effects of factors in aggregate demand on growth through multipliers Thirlwall (1979), a post-Keynesian economist, considers demand, especially international trade, as a principal cause of accelerating or constraining growth in the long run, in other words, growth rate in open economies can be constrained by external demand The author also suggests that the dominant constraint upon demand is balance of payments in an open economy and his model is so called balance of payments constrained economic growth model (BPCG) However, his first generation of BPCG model has many limitations in explaining growth performance in developing countries As a result, the extended model was later developed by Thirlwall and Hussain (1982), which is also known as the second generation of BPCG model, considering the impacts of foreign capital flows The Balance of Payment constrained growth model with basic concepts that actual economic growth rate cannot be higher than the estimated rates used by BOP model except for having capability to finance the deficit Current account would be in deficit if import is larger than export, and thus sources of finance must be sought to meet the need of shortfall by either from borrowing abroad, and/or from net transfer, DFI, i.e via growing of capital inflows Total income or aggregate demand mentioned above is defined as a function of consumption, investments, government expenditure, and exports In contrast to the case that all other components of aggregate demand depend on the country total income, export depends on the world total income Assuming that there is no export and no capital inflow, aggregate demand would be repressed certain elements of aggregate demand because of insufficient foreign currency For example, if there is no foreign currency to support for importing modern machinery and equipment which are used for domestic production, it would lead to several issues such as increase in unemployment, or resources underutilization More easily, if we still have export but rate of growth of imports is higher than exports, capital inflow can initially abate aggregate demand repression in the short term However, trade deficits, in reality, cannot be financed endlessly by capital inflow and this would lead to aggregate demand will be constrained by BOP Balance of payment constraint can affect aggregate demand in the short term or long term; or this will slow down economic growth In other words, economic growth has to be run in balance of payments constraint Beside that we cannot deny the role of factors supply and technological progress in economic growth but it is very precious to bear in mind that "in most countries demand constraints tend to bite long before supply constraints are ever reached" (Thirlwall, 2002) Considering the period from 1990 to 2010, Vietnam achieved very high annual economic growth rates, except three years 1998 (5.8%), 1999 (4.8%) after Asian financial crisis and 2009 (5.32%) after global financial crisis This is considered as one of achievements of appropriate “open door” policies by relaxing exchange rate controls, internal and external trade impediments As a result, export growth and import growth increase, except for 1996 and few years later when government decided to establish restrictions on import due to alarming current account deficit(1996:-11.5% of GDP) Although export growth rate is sometimes higher than import growth rate, but it is still smaller than import growth in absolute values in most of the years in the period of 1990-2010, trade deficit therefore still exists Furthermore, trade deficit is a chronic issue in Vietnam because of imports-exports structure, as less of competiveness in exporting sector as it mainly comprises of low value-added goods, raw materials and intermediate products Current account is in deficit as a consequence of deficit in trade balance Figure 1: GDP growth 1990-2010 12.00 10.00 8.00 6.00 4.00 2.00 2010 2009 2008

accordingly because this may be compensated by capital account surplus Obstinate current account deficit following by capital account surplus, for example, borrow from aboard, FDI, is not sustainable in the long run because one country cannot infinitely borrow abroad to finance current account deficit Financing the deficit by FDI can help the BOP balance and keep the economic growth in the short term, but in the long term this also makes unsustainable growth as it relies on the external sources The fluctuation in FDI flow would lead to negative impacts on domestic economy such as uncontrollable production, unemployment rate and therefore economic growth Balance of payments problems may happen not only with developing countries but also with developed countries However, it is often referred to the developing world The aim of this paper is to re-apply the Thirwall’s law of balance of a payments constraint on economic growth on the Vietnam economy with the new scenario recently by comparing it with potential growth rate by using time series data extending over two decades with the period 1990-2010 1.2 Research questions This study is to examine Whether balance of payments in Vietnam constrained economic growth or not? Which factors behind balance of payments restrict economic growth? What policy implications are for the balance of payments constrained economic growth in Vietnam? 1.3 Structure of Study The thesis includes chapters starting with the introduction in Chapter 1.Chapter subsequently provides literature review for thesis Next, Chapter provides the overview economic growth and balance of payments of Vietnamese scenario Chapter shows the model specifications and the findings Chapter eventually shows the conclusion and further recommendation CHAPTER II: LITERATURE REVIEW 2.1 Theories The balance of payments constrained growth model, which was developed by Thirlwall’s (1979), identifies the long run the economic growth rate of open economy constrained by trade balance By Thrilwall, the growth rate equilibrium can be defined by the ratio of export growth rate and the income elasticity of demand for imports This model has been tested not only with a large sample of developing and developed countries around the world but also tested by many different techniques and methods With the first generation of BPCG, the author ignored international capital flows and interest payments However, capital flows and interest payments are an important part of the BOP As a result, Thirlwall and Hussain (1982) developed the extended model from the original model to allow trade deficits and capital inflow This model shows that in an open economy the growth rate may be constrained by capital inflows together with trade factors which mean that capital inflows tighten or loosen the balance of payment constrained growth To improve the capital inflows limitation, BPCG model was redefined by Moreno-Brid (1998, 1999) with the assumption that accumulating foreign debt has sufficient condition It combines interest payments from imports of goods with non-factor services in the analysis of debt accumulation In his research, McCombie (1997), the author tested with time series data for many nations in the short run He found that balance of payments equilibrium may delay the consistent growth rate with the exports and imports growth rate For example, if growth rates are higher than the consistent level with the external account equilibrium then the capital inflows will fulfill 10 Besides, there are problems with FDI, debt and financial investment portfolio As analyzed in previous chapter, FDI has negative effects on both current account and capital account, especially on trade balance since it may contain risks and can also easily get inflicted from adverse shocks in economic and political environments in Vietnam together with region, caused by expectation of foreign investors Other short term capital inflows such as portfolio investment and other types of international financial flows are more exposed to volatility in economy or political change than FDI therefore the risks are also considered higher Vietnam cannot have large capital inflows and trade deficit forever in order to achieve high economic growth Thus this creates a need some policy applications under balance of payments constraint to solve this problem 4.2 Recommendation In order to achieve high growth rate, Vietnam needs to reduce the balance of payments constraint therefore I propose a focus on trade balance that includes exports and imports, FDI and external debt which contribute to main parts in BOP of Vietnam First, I suggest a policy to promote exports by encouraging diversification of exports markets such as approaching and targeting new markets instead of traditional markets, and subsidize new export products as well to mitigate market risks Additionally, the government can play an important role to solve the new market failure problem (Stiglitz, 2002) by putting more efforts to reduce the asymmetric information problems in such a way of providing investors with more comprehensively and timely information regarding market conditions The structure of exports should target to improving productivity, moving domestic production structure to high value added products, terminating protection for inefficient industries and state owned enterprises Besides, the government can support domestic 42 entrepreneurs by building good infrastructures in order to reduce the costs and time of production, helping production firms enter and exit market more easily Second, I propose that government should support for production firms to produce intermediate goods domestically because Vietnam imports virtually capital and intermediate goods for production and exports On the other hand, if it fears large deficits in trade deficit and current account and restrict imports, this will hamper economic growth This measure is temporary one only In long-term, the government needs to encourage diversification in market and structure of exports to obtain foreign exchange for imports Moreover, the government should give suitable routes to open domestic market to pressurize protected industries into strengthening capacity of competitiveness Third, it is noticeable as analyzed above that capital flows in Vietnam are not only equity but also debt which raise the cost of financing the current account deficit In order to fill the gap of trade deficit and current account deficit, the government should attract inflow of FDI by focusing more on creating a transparent legal framework and create a good market environment for all foreign investors, aiming to reduce inefficient enterprises and increasing efficient enterprises to provide better allocation of resources The government should prioritize FDI producers which can manufacture intermediate goods for the production inputs By doing so, the country can reduce the imports which leads to decrease in trade deficit Furthermore, the government should encourage FDI producers to invest in high tech industries, which can improve the value added feature of domestic production goods including export goods It is also noteworthy to mention that a better legal framework also means an improved investment laws to meet the international standards, which is vital since Vietnam is effectively a member of WTO, creating fairer treatments between domestic and foreign investors and reducing corruption opportunities 43 Last but not least is the issue of external debt which includes risk and cost Although most of debts are concessionary, long maturity, no bunching for repayments (IMF, 2009), there is a steady increase in non-concessionary loans and the government should evaluate and consider the allocation of capital inflow to the most efficient projects and programs to make use of better financing 4.3 Limitation Just like any regular research project, although I have aimed at my best to address and mitigate the arisen issues, there are some aspects that could be improved such as in the data collecting stage The data is gathered from several sources and in some case it could mean lack of reliability It is notable that due yearly data is not enough for the length required for running regression even though it is better when using yearly data for this thesis Secondly, policy implications cannot be conducted with more details because of the limitations of model use It is recommended that government should make structure of export more diversify Within the areas discussed in this thesis, the question of how to change the structure still remains open Hopefully in the future, yearly data can be obtained and detailed of how to change would be addressed in more appropriate depth and details 44 APPENDIXES Appendix 1: OLS Regression
