UNIVERSITY OF ECONOMICS ERASMUS UNVERSITY ROTTERDAM HO CHI MINH CITY VIETNAM INSTITUTE OF SOCIAL STUDIES THE NETHERLANDS VIETNAM – THE NETHERLANDS PROGRAMME FOR M.A IN DEVELOPMENT ECONOMICS AN ANALYSIS OF THE ECONOMIC EFFICIENCY OF THE BANKING SECTOR IN VIETNAM BY NGUYEN THI PHUONG THAO MASTER OF ARTS IN DEVELOPMENT ECONOMICS HO CHI MINH CITY, NOVEMBER 2015 i 123doc ABSTRACT This study measures economic efficiency of commercial banks in Viet Nam and its determinants The Stochastic Frontier Model is applied for a profit function We include internal factors (including price of fund, price of physical capital, price of labor, price of loan and price of other earning assets) and macroeconomic factors (economic growth, inflation rate, and other macroeconomic environment variables) in the profit function The empirical results show that the efficiency of Vietnamese commercial banks seems to be fluctuated steeply over the period 20082013 In terms of the efficiency of different groups of commercial banks, the profit efficiency of the State-owned commercial banks and Private commercial banks follow different trend Particularly, the state owned commercial bank’s group seems to have extremely higher profit efficiency score then private commercial bank ii 123doc LIST OF ABBREVIATION LSDV Least squares with dummy variables GLS Generalized least squares SFA Stochastic Frontier

the national economy operates smoothly Banking industry is widely considered as the backbone of an economy and highly regulated in many countries Banks usually has been considered as key players in providing capital and stimulating economic development In the study of Demirguc & Huizinga (2000), it showed that when an economy is developed at a certain level, it requires an intensive support from the stable and sustainable national financial system Prior studies in the body of literature indicate that there are a wide range of factors affecting the bank efficiency which can be classified into two main groups namely external factors (e.g macroeconomic factors and industrial factors) and internal factors of commercial banks (e.g size, losses, liquidity, and other factors) Particularly, Hasan and Marton (2003) examines the relationship between the development and efficiency of banking sector while Hou, Wang, and Zhang (2014) measure the linkages among market structure, risk taking and efficiency of commercial banks Due to their importance on the financial sector and their influence on the national economy, this sector requires a high regulation by the government However, in most developing countries like Vietnam, there is lacks of perfect regulation to support this sector to stabilize and develop Like other countries, the banking system in Vietnam provides many products from retail banking such as saving accounts, deposits, credit/debit card, mortgage, loans to commercial banking such as business loan, capital equity, risk management, and credit services As commercial banks have evolved in Vietnam before the investment banks, this service is one of the most sensitive business which suffers direct and indirect impacts on several intrinsic obstacles of the economy as well as the external effects, thus stabilizing the currency and the banking system play an important factor, primarily in the financial system stabilization Therefore, understanding the efficiency of the banking system as well those factors affecting the banking operations attracts a lot of attention from many economists and scholars all over the world In measuring efficiency, people usually choose between technical efficiency and economic efficiency We choose economic efficiency as this is more comprehensive In this thesis, the profit function is used to measure economic efficiency

Luan an Do an Vietnam – Netherlands Programme for M.A in Development Economics Research objective While the capital funds raised for the national economy from those commercial banks are enormous, limited research was carried out about how these banks operate and whether they operate efficiently With a proper measurement about banking efficiency together with a wealth of predictive determinants will help the public to indicate how well a certain commercial bank operate in the competitive market like Vietnam Secondly, by improving the performance of individual banks, the whole national banking system will function much more efficiently and effectively However, at the moment, most of studies focused on qualifying the efficiency of the commercial banks (Nguyen, Roca, & Sharma, 2004) or determining certain large-scale economic factors affecting commercial banks (Athanasoglou, Brissimis, & Delis, 2008) without quantifying these factors to rank these commercial banks in the global scale Hence, the aim of this thesis is to verify the connection between the current financial growth at the national scale and the efficiency performance of commercial banks in Vietnam In details, this thesis is to understand the connection between the economic efficiency and the economic growth of the banking system based on two following smaller objectives:  How efficient are commercial banks in Vietnam?  Which factors affect the economic efficiency of commercial banks? This is the research of Vietnamese banks efficiency that will convey the managers to identify the banks’ weakness as well as the causes of those weaknesses so that they can come up with the right strategies, which will bring the best result given the same level of resource inputted In addition, this will be a useful research to analyze inefficiencies and minimize it in order to improve the performance of Vietnamese banking industry Moreover, this research also demonstrates the reality of Vietnamese banking industry, which will be a useful guide for foreign investors to start financing their equity in this dynamic industry Stt.010.Mssv.BKD002ac.email.ninhd 77.99.44.45.67.22.55.77.C.37.99.44.45.67.22.55.77.77.99.44.45.67.22.55.77.C.37.99.44.45.67.22.55.77.77.99.44.45.67.22.55.77.C.37.99.44.45.67.22.55.77.77.99.44.45.67.22.55.77.C.37.99.44.45.67.22.55.77.77.99.44.45.67.22.55.77.C.37.99.44.45.67.22.55.77.77.99.44.45.67.22.55.77.C.37.99.44.45.67.22.55.77t@edu.gmail.com.vn.bkc19134.hmu.edu.vn.Stt.010.Mssv.BKD002ac.email.ninhddtt@edu.gmail.com.vn.bkc19134.hmu.edu.vn 123doc C.33.44.55.54.78.65.5.43.22.2.4 22.Tai lieu Luan 66.55.77.99 van Luan an.77.99.44.45.67.22.55.77.C.37.99.44.45.67.22.55.77.C.37.99.44.45.67.22.55.77.C.37.99.44.45.67.22.55.77.C.33.44.55.54.78.655.43.22.2.4.55.22 Do an.Tai lieu Luan van Luan an Do an.Tai lieu Luan van Luan an Do an Vietnam – Netherlands Programme for M.A in Development Economics Chortareas, G E., Garza-García, J G., and Girardone, C (2012) Competition, efficiency and interest rate margins in latin american banking International Review of Financial Analysis, 24(0), 93-103 Coelli, T J., Rao, D S P., O’Donnell, C J., and Battese, G E (2005) Data envelopment analysis An introduction to efficiency and productivity analysis (pp 161-181): Springer US Delis, M D (2012) Bank competition, financial reform, and institutions: The importance of being developed Journal of Development Economics, 97(2), 450-465 Economist Intelligence Unit (2005) Vietnam regulations: Banking sector is liberalising (pp n/a-n/a) New York, United States Färe, R., Grosskopf, S., and Lovell, C A K (1988) Scale elasticity and scale efficiency Journal of Institutional and Theoretical Economics (JITE) / Zeitschrift für die gesamte Staatswissenschaft, 144(4), 721-729 Farrell, M J (1957) The measurement of productive efficiency Journal of the Royal Statistical Society, 120(3), 253 -
