EFFICIENCY AND SUPER-EFFICIENCY OF COMMERCIAL BANKS IN VIETNAM: PERFORMANCES AND DETERMINANTS

This paper estimates and compares efficiency performance of 32 commercial banks in Vietnam during 2001–2005, as well as identifies possible factors determining such efficiency performance. Efficiency is measured by a data envelopment analysis (DEA) model and super-efficiency measure through a slacks-based model (SBM) under the assumption of variable returns to scale (VRS). We find that there were a small number of efficient banks, and there would be room for these banks to improve their production efficiency. Moreover, in comparison with small banks, large banks do not guarantee high super efficiency scores. The results from a Tobit regression model provide such interesting findings as negative impact of state ownership, positive influence of bank size and market share, but no impact of labor quality.

Super Efficiency and Misallocation: Evidence from Vietnamese Electric-Computer Industry

Misallocation means that the source is not distributed efficiently. This leads to an important question of how the relationship between misallocation and efficiency is (see [1]). The purpose of this study is to address the empirical relationship between misallocation and efficiency in the electric and computer industry in Vietnam during the 2005-2015 periods. To do this, we built a model that allowed us to evaluate the impact of misallocation and other factors on efficiency. The slack-based measured efficiency (SBM) model (Tone [2]), and the super-efficient model (Tone [3]) are used to estimate the firms’ efficiency. The approach of Hsieh and Klenow [4] is used to measure misallocation in the study area. Estimated results of the model about the relationship between misallocation and efficiency show that the variable representing the misallocation has a negative sign and statistical significance in all models. In other words, the misallocation negatively affects efficiency. The bigger the misallocation, the lower the efficiency.

FDI and Efficiency Convergence, the Case of Vietnamese Manufacturing Industry

Aims: The scope of this study is twofold. We aim to test efficiency convergence hypothesis among firms in Vietnamese manufacturing industry, and to analyze the influence of foreign direct investment (FDI) on efficiency and efficiency convergence. Study Design: Case study Place and Duration of Study: Technical efficiency measures are derived for a sample of Vietnamese manufacturing firms during 2000-2012 Methodology: nonparametric data envelopment analysis (DEA). The approach to find the impacts of FDI on efficiency and efficiency convergence through horizontal and vertical spillover effects is to construct the linkages from dynamic input - output tables. The way to test unconditional convergence in the two technical efficiency measures from DEA is used the regression in the form
