Investigating the Economic Relationship between Provinces in Vietnam: A Spatial Regression Approach
Xuan Vinh Vo,Thi Tuan Anh Tran,Van Thang Nguyen 중앙대학교 경제연구소 2020 Journal of Economic Development Vol.45 No.1
To develop provincial economies, it is necessary to focus on not only the internal resources of a province but also the relationship among provinces which can lead to the spillover effect throughout the country. This paper examines the economic relationship and spillover effect between provinces in Vietnam by spatial regression approach with data collected from 2010 to 2017 from statistical yearbooks. The results show that there exists a spatial correlation between provinces in terms of provincial gross domestic product, capital investment and labor force. The results also demonstrate that capital and labor factors not only affect the gross domestic product of the host province but also affect the neighboring ones. The finding implies the significant spillover effect between provinces.

Objectives: The incidence of posttraumatic stress disorder (PTSD) has increased, particularly among individuals who have recovered from coronavirus disease 2019 (COVID-19) infection. Health literacy is considered a “social vaccine” that helps people respond effectively to the pandemic. We aimed to investigate the association between long COVID-19 and PTSD, and to examine the modifying role of health literacy in this association.Methods: A cross-sectional study was conducted at 18 hospitals and health centers in Vietnam from December 2021 to October 2022. We recruited 4,463 individuals who had recovered from COVID-19 infection for at least 4 weeks. Participants provided information about their sociodemographics, clinical parameters, health-related behaviors, health literacy (using the 12-item short-form health literacy scale), long COVID-19 symptoms and PTSD (Impact Event Scale-Revised score of 33 or higher). Logistic regression models were used to examine associations and interactions.Results: Out of the study sample, 55.9% had long COVID-19 symptoms, and 49.6% had PTSD. Individuals with long COVID-19 symptoms had a higher likelihood of PTSD (odds ratio [OR], 1.68; 95% confidence interval [CI], 1.63–2.12; p<0.001). Higher health literacy was associated with a lower likelihood of PTSD (OR, 0.98; 95% CI, 0.97–0.99; p=0.001). Compared to those with long COVID-19 symptoms and the lowest health literacy score, those with long COVID-19 symptoms and a 1-point health literacy increment had a 3% lower likelihood of PTSD (OR, 0.97; 95% CI, 0.96–0.99; p=0.001).Conclusion: Health literacy was found to be a protective factor against PTSD and modified the negative impact of long COVID-19 symptoms on PTSD.

Financing Decision and Labor Cost: Evidence from South Asian Countries
Thi Phuong Vy Le,Xuan Vinh Vo 중앙대학교 경제연구소 2020 Journal of Economic Development Vol.45 No.1
This study investigates the effect of financial leverage on labor costs using a data sample of listed companies from Southeast Asian countries covering the period from 2009 to 2015. Using several techniques for robust results, the results show that financial leverage has a negative effect on labor costs. In addition, the study finds that the negative impact of financial leverage on labor cost tends to be less in state-owned, foreign-owned, and large companies.

Accruals Quality, Stock Returns and Information Risk: Evidence from Vietnam
Thi Ngoc Lan Nguyen,Mai Nguyen,Viet Dzung Nguyen,Xuan Vinh Vo 중앙대학교 경제연구소 2024 Journal of Economic Development Vol.49 No.2
Prior studies on whether information risk is relevant for asset pricing have mixed findings across different countries. This study aims to re-examine this risk in an emerging market such as Vietnam. Using data from two stock exchanges in Vietnam, we investigate (1) if there are evidence of mispricing among accrual quality (AQ) portfolios and (2) whether the AQ factor is useful in explaining the time series portfolio returns. We further examine whether AQ measured by innate accruals and discretionary accruals is a priced risk factor by using the two-stage cross-sectional model suggested by Core et al. (2008). Our findings demonstrate that AQ does explain the time-series variation in returns of 06 size-BM portfolios, and AQ portfolios are overpriced in the Vietnamese stock market. However, we find no evidence that AQ is a priced risk factor in such inefficient Vietnamese. This might be because unprofessional investors are unaware of earnings management embedded in each component of AQ and the lack of transparency in the equity market.
