The Vietnamese privatization programme, launched in 1992, differs from the usual Western privatization programmes in terms of the residual percentage of shares owned by the state and the portion of shares owned by insiders. This begs the question whether these differences influence the effects of the programme on firm performance. This study measures the impact of privatization on firm performance in Vietnam by comparing the pre-and post-privatization financial and operating performance of 121 former state-owned enterprises (SOEs). We find significant increases in profitability, sales revenues, efficiency and employee income. Results of applying the 'difference-in-difference' (DID) method, wherein a control group of firms is used to pick up the influence of other determinants of firm performance, suggest that the performance improvements may indeed be associated with equitization. Regression analyses reveal that firm size, residual state ownership, corporate governance and stock market listing are key determinants of performance improvements.

This study investigated the impact of the introduction of the VN30-Index futures contract on the daily returns anomaly for the Ho Chi Minh Stock Exchange (HOSE). Daily returns of the VN30-Index for the period 6 February 2012 through 31 December 2019 are used in this study to ascertain the new VN30-Index futures contract influence on the day-of-the-week anomaly observed in the HOSE. To test this effect, ordinary least square (OLS), generalized autoregressive conditional heteroskedasticity [GARCH (1,1)] and exponential generalized autoregressive conditional heteroskedasticity [EGARCH (1,1)] regression models were employed. The empirical results obtained from the models support the presence of the day-of-the-week effect for the HOSE during the study period. Specifically, a negative effect was observed for Monday. However, the analysis revealed that the day-of-the-week effect was only present in stock returns for the pre-index futures period, not for the post-index futures period. These findings suggest that the introduction of the VN30-Index futures contract had a significant impact on the daily returns anomaly in Vietnam’s HOSE, providing evidence that the introduction of the index futures contract facilitated market efficiency.

The objective of this study is to enrich the literature by investigating the impact of introduction of index future trading on spot market returns and trading volume in Vietnam. Data used in this study mainly consist of daily VN30-Index and market trading volume series during the period from February 6 th , 2012 to December 31 st , 2019. Using OLS, GARCH(1,1) and EGARCH(1,1) models, the empirical findings consistently confirm that the introduction of index future trading has no impact on the spot market returns. In addition, the results of the EGARCH(1,1) model indicate that the leverage effect on the spot market volatility is existence in HOSE. Specifically, bad news has a greater effect on the market volatility than good news of the same size. Moreover, our empirical findings reveal that the introduction of index future contracts has the positive impact on the underlying market trading volume. Specifically, the trading volume of the post-index futures introduction increases by 7.5 percent compared with the pre-index futures introduction. Finally, the results obtained from the Granger causality test for the relationship between the spot market returns and the future trading activity confirm that only uni-directional causality running from the market returns to the future trading activity exists in HOSE.

Purpose This study aims to investigate the moderating effects of subsidiary size on the association between institutional distance and subsidiary’s access to complementary local assets (ACLA) in a transition economy. Design/methodology/approach The data of 1,027 subsidiaries located in Vietnam were extracted from the survey of General Statistics Office of Vietnam. Hausman’s test shows that random effect model is appropriate to estimate the moderating effects of subsidiary size on the association between the institutional distance and subsidiary’s ACLA. Findings The findings revealed that the greater formal and informal institutional distances between home and host countries, the lower a subsidiary’s ACLA in a transition economy. In addition, larger subsidiaries’ ACLA in a more formal and informal institutional distant country are higher than smaller subsidiaries. Research limitations/implications Multinational enterprise (MNEs) have a continuous need to use their foreign subsidiaries operating in host countries, particularly those with transition economies, to overcome institutional differences to ACLA in a transition economy. In addition, subsidiaries should be invested with greater resources to collaborate with local partners to serve for accessing to complementary local assets in transition economy characterized by an uncertainty institutional environment. Originality/value By integrating the institutional theory and the resource-based view, the study developed a theoretical model about the moderating role of subsidiary size on the association between institutional distance and subsidiary’s ACLA in transition economy. The findings confirmed that simultaneously applying the institutional theory and the resource-based view to investigate location-specific advantages exploitation of subsidiaries is relevant not only in developed economies but also in a transition economies.
