Volatility of stock exchange and its determinants always attract the attention of investors, researchers and exchange authorities. The research estimates the volatility of Vietnam stock market by measuring the conditional volatility of VN-Index and HNX-Index, and explores the relationship between the volatility of stock exchanges and the volatility of two instruments of monetary policy (overnight rate and exchange rate). Data are collected on a daily basis from Jan. 5, 2006 to March 31, 2014. The research found evidence of volatility of returns through the two indexes and two instruments, but it detected no relationship between the volatilities of these instruments and the stock indexes. Additionally, the research confirms the role of VN-Index as a market maker over HNX-Index.
Although Vietnam’s economic growth and poverty reduction for almost three decades have been remarkable, growth for poverty reduction is unequally distributed across the nation. The paper examines the cause of poverty and the impact of provincial economic growth on poverty alleviation, using the data of 63 provinces in Vietnam. The elasticity of poverty with respect to provincial economic growth is employed (the elasticities of headcount index, poverty gap index, and squared poverty index with respect to provincial economic growth) to identify the provinces where pro-poor growth has occurred. The elasticity of poverty with respect to provincial Gini coefficient is examined to identify the impact of expenditure inequality on poverty. The simultaneous equation system is estimated to analyze not only direct and indirect effects of the related variables, but also the causality effect between economic growth and the poverty elasticity with respect to both growth and the Gini coefficient.
The paper aims at exploring the relationship between bad debt and cost efficiency in Vietnamese commercial banks in the years 2007 – 2013. The research includes two stages: (i) Measuring the cost efficiency of banks by non-parameter Data Envelopment Analysis (DEA) method suggested by Coelli (2005); and (ii) Applying the Tobit model to identify two-way effects of bad debt and bank cost efficiency. The results show that the cost efficiency in Vietnamese commercial banks is 52.6% and there exists a direct relationship between bad debt and cost efficiency.
The paper is based on Resolution of CPV National Congress XI and Conclusion of the third conference of CPV Central Executive Committee of term XI on restructuring of the economy and innovation in growth model which has been institutionalized and implemented as a central task for the whole 5-year Socioeconomic Development Plan 2011-2015. The implementation of the plan has produced several important results along with certain shortcomings that should be dealt with in the coming years. This paper provides some general estimates of the socioeconomic development in recent years and offers some directions and solutions needed for promoting the restructuring of the economy and innovation in the growth model up to 2020.
Budgeting is widely advertised as an effective managerial accounting tool but has been criticized mainly for budgetary slack reason. The purpose of this article is therefore to empirically examine relationships between budget participation, budget emphasis, risk awareness, private knowledge and the propensity to create budgetary slack. This study also extends the previous research by testing the hypothesized effect of the nonfinancial managerial accounting information use on various factors associated with the propensity to create budgetary slack. A survey data from 243 Vietnamese enterprises was used to conduct a structural equation modeling analysis. The results indicate that budget participation and budget emphasis incrementally affect the propensity to create budgetary slack while nonfinancial managerial accounting information is fairly useful to limit human aspects of budgeting. In addition, no correlation between private knowledge and creation of budgetary slack by subordinates was found. Once again, the results of this research confirm the effects of human factors in budgeting, which measured in a Vietnamese business environment and extended the understanding of the role of nonfinancial managerial accounting information in improving the budgeting process.
Using disaster data from the emdat.be website and data for six regions in Vietnam, this paper investigates the impacts of natural disasters on the gross product per capita of the three rural sectors that have been affected the most by disasters―agriculture, fishery, and forestry―over the period 1995 to 2013. The preliminary tests reveal endogeneity and contemporaneous correlations among these three sectors. Hence, a combination of instrumental variable (IV) estimations and system seemingly unrelated regressions (SSUR) are employed. The results reveal that disasters have different impacts on different sectors of the rural Vietnam with agriculture suffering the heaviest losses, fishery second, and forestry suffers the least. We then analyze the effects of reforestation as a disaster prevention measure and provide forecasts on the forest development in Vietnam.
The research aims at identifying characteristics of teamwork that affect the teamwork effectiveness in management and exploitation of airports in Vietnam. Applying relevant theories adjusted to fit the specific conditions in Vietnam, the research finds 15 differences in characteristics of teamwork from the original model by Campion et al. (1993). Teamwork effectiveness is determined by two components: team productivity and employee satisfaction. The quantitative research employs proportionate stratified sampling to gather 434 samples and applies two multiple regression models. The results identify 14 characteristics that can help improve the team work effectiveness. The research contributes important evidence of impacts of characteristics of teamwork on teamwork effectiveness in the management and exploitation of airports.
The research aims to apply KMV-Merton model to calculate and forecast default probability (DP) among corporate customers of Vietcombank. Analyzing data from financial statements of 6,398 corporate customers in the years 2008–2012/2013, the research shows that the DP of the whole customer portfolio is 2.6%, equaling a loss of VND6,319 billion, or 3.8% of outstanding loans to the portfolio. The results also show that small-sized companies have smaller DP as compared to larger ones. Regarding industries, the lowest DP is found in road and waterway transport business, and the highest is in electricity (including production, transmission and distribution),
production of other kinds of power, and seafood processing business. Industries with high DP and outstanding loans may cause the greatest damage to banks. The research concludes that large-sized companies and seafood processing enterprises cause the greatest losses to banks.
