Factors of Value Chain Affect Bank Efficiency

This paper aims to determine and estimate the factors in the value chain that affect the efficiency of state-owned commercial banks in Vietnam. The study employs a combination of qualitative techniques, such as conducting interviews with top executives, financial managers, chief accountants, and employee surveys, along with quantitative methods like ordinary least squares analysis. The outcomes reveal four critical segments within the value chain – the retail department, operation department, back office, and call center – all of which significantly influence the efficiency of the banks. Additionally, drawing upon value chain theory and Porter's model (1985), the author underscores the significance of implementing a robust value chain strategy. This strategic approach has the potential to substantially enhance the competitive advantages of state-owned commercial banks in Vietnam. Doi: 10.28991/ESJ-2023-07-06-010 Full Text: PD

Corporate Social Responsibility and Bank’s Performance under the Mediating Role of Customer Satisfaction and Bank Reputation

This paper aims to examine the indirect linkage between corporate social responsibility (CSR) and firm performance via the effects of customer satisfaction and bank reputation. The study applies Structural Equation Modelling (SEM) to a sample of top managers, finance managers, chief accountants, and employees in Vietnamese state-owned commercial banks. The findings explore the statistically significant effect of CSR on bank performance under the mediating role of customer satisfaction and bank reputation, which are not concerned by previous studies. Because CSR activities assist banks in maintaining their reputation by complying with a long-term commitment to stakeholders' interests and providing valuable customer benefits to increase their satisfaction. So, the research results show that customer satisfaction and the bank's reputation promote a positive relationship between CSR and bank performance. Doi: 10.28991/ESJ-2022-06-06-012 Full Text: PD

Does National Governance Affect the Capital Structure of Listed Firms during the COVID-19 Pandemic?

This study estimates the macro-economic factors affecting the listed small and medium enterprises' capital structures in Vietnam from 2010 to 2020. The author conducts the quantitative method (generalized method of moments—GMM) with valid instrument variables to solve the endogeneity in regression models, which refers to the determinants of capital structures. Based on the trade-off theory and the pecking order theory, the author provides evidence of macro-economic factors and firm-specific factors in explanations for the capital choices of the Vietnamese firms, including national governance, inflation, COVID-19, firm age, and asset structure. In particular, this study highlights how national governance and COVID-19 influence the capital structure of small and medium enterprises in Vietnam. Doi: 10.28991/ESJ-2023-SPER-04 Full Text: PD

Determinants of stock market modern development: Evidence from Vietnam

The paper estimates the macroeconomic variables affecting the stock price in Vietnam from 2009 to 2019. Based on the used autoregressive distributed lag (ARDL) model, the test shows a co-integration between stock prices and macroeconomic factors. The findings explore the optimal delay in the ARDL model as (1, 2, 1, 2, 0, 0, 2). Concretely, statistically significant evidence proves that the consumer price index, gross domestic product, interest rate, money supply, and oil price are the determinants of the stock price in Vietnam. In particular, the consumer price index and GDP have a direct relationship with the stock market, while interest rate, money supply, and oil price have opposite effects

Some Characteristics And Allopurinol Release Of Carrageenan/ Allopurinol Films Using Polyethylene Oxide As A Dispersion Aid Agent

This paper presents the effect of carrageenan (CG) on some characteristics and drug release of allopurinol in the presence of polyethylene oxide (PEO) as a dispersion aid agent. The samples were prepared in film shape by solution method, in which, the content of PEO was changed from 1 wt.% to 5 wt.% and the content of allopurinol was fixed at 10 wt.% in comparison with carrageenan weight. FTIR , FESEM, UV-Vis methods were used to evaluate characterizations and morphology of CG/PEO/allopurinol films

Trade Liberalization and Development in ICT Sector and its impact on household welfare in Viet Nam

The ICT sector in Viet Nam had not been developed until the 1980s. However, over the last decade of rapid growth, it has had a powerful impact on many aspects of life in this country. Although the ICT sector is still at an early stage of development and lags behind many other countries in the region, the government of Viet Nam made strong commitments to upgrade the nation’s ICT capability and implemented significant reforms in terms of trade and investment liberalization in ICT sector over the last decade.Trade Liberalization, ICT, Household welfare, Viet Nam

Performance of export-oriented small and medium-sized manufacturing enterprises in Viet Nam

The study recommends the formulation of policies that support the development of business linkages and networking, and which promote subcontracting arrangements between small and large enterprises or between domestic firms and foreign investment enterprises. It is also necessary to support and facilitate the direct involvement of SMMEs in exporting or indirectly through large manufacturing enterprises.Export-oriented, SME,SMME, Viet Nam

Multihop Decode-and-Forward Relay Networks: Secrecy Analysis and Relay Position Optimization

Relay communication has advantages over direct transmission in terms of secrecy capacity. In this paper, the performance of secrecy, offered by multihop decode-and-forward relaying, is investigated and compared to its counterpart in direct transmission. Three key performance measures are derived over Rayleigh fading channels: probability of non-zero secrecy capacity, secure outage probability and secrecy capacity, which are valid for an arbitrary number of hops. Based on the tractable form of the probability of non-zero secrecy capacity, the optimization problem of trusty relay replacement is also studied. Numerical results indicate that a proper relay replacement can increase the network security without extra network resources. The correctness of analytical results is confirmed by using a MATLAB-based independent simulation model
