Abstract
Purpose
This study aims to investigate aspects related to the changing trends of the rainfall extremes in the entire Mekong Delta in the period of 32 years (1984-2015) applying rainfall extreme indices. First, the homogeneity tests were applied to assess the quality of observed rainfall data series. The authors, then, investigated three rainfall indices including the number of very heavy rainfall days 20 mm (R20), number of days above 50 mm (R50) and number of days above 100 mm (R100) applying the Mann-Kendall test and Sen’s slope estimate.
Design/methodology/approach
First, the homogeneity tests were applied to assess the quality of observed rainfall data series. The authors, then, investigated three rainfall indices including the number of very heavy rainfall days 20 mm (R20), number of days above 50 mm (R50) and number of days above 100 mm (R100) applying the Mann-Kendall test and Sen’s slope estimate.
Findings
The results of R20 pointed out that an insignificant upward tendency was found in the coastal provinces, whereas an insignificant downward tendency was also recorded in the inland provinces. Regarding the number of R50, a similar trend to R20 was recorded with five stations slightly increased and five stations slightly decreased. For the number of R100, the results recorded an absence of significant trends over the entire study area. Approximately 58.5% of stations show a slightly decreasing trend, while 41.5% of the remaining stations recorded a slightly increasing trend.
Originality/value
For the number of R100, the results recorded an absence of the significant trends over the entire study area. Approximately 58.5% of stations show a slightly decreasing trend, while 41.5% of the remaining stations recorded a slightly increasing trend. Of note is the fact that the number of R100 occurred more frequently in the northern provinces, which means the northern region is facing a high risk of flooding.

The purpose of this study was to evaluate how higher tax on tobacco would influence output and employment in Vietnam.
Abstract
Purpose
The purpose of this study was to evaluate how higher tax on tobacco would influence output and employment in Vietnam.
Design/methodology/approach
The authors used micro-simulation techniques proposed by Walbeeck (2010). Both national data (from Input–Output Table) and household data (Vietnam Household Living Standard Survey) were utilized.
Findings
The results showed that any increase in the excise tax for tobacco would have positive net impacts on both national output and employment. The tobacco industry would not be significantly affected due to its small contribution to national economy and employment. More importantly, money released from reduced tobacco consumption would be reallocated to other goods and services, and thus outputs and jobs in nontobacco sectors would increase.
Research limitations/implications
The key limitation of this study was due to unavailability of updated data, especially Input–Output Table as well as household living standard survey.
Practical implications
This study concluded that government should increase tax on cigarette along with a well-planned roadmap to avoid unexpected consequences on income and employment of laborers in this sector.
Originality/value
This study replicated a popular approach in order to verify an important government policy (i.e. effect of tax on tobacco on output and employment) under Vietnamese context.

The purpose of this paper is to estimate the impact of credit rationing on the amount of capital allocated to inputs used by rice farmers in the Mekong River Delta (MRD).
Abstract
Purpose
The purpose of this paper is to estimate the impact of credit rationing on the amount of capital allocated to inputs used by rice farmers in the Mekong River Delta (MRD).
Design/methodology/approach
Based on the literature review, the authors propose nine hypotheses on the determinants of access of rice farmers to credit and four hypotheses on the impact of credit rationing on the amount of capital allocated to inputs used by rice farmers in the MRD. Data were collected from 1,168 farmer households randomly selected out of 10 provinces (city) in the MRD.
Findings
Step 1 of propensity score matching (PSM) with probit regression shows that land value, income, education, gender of household head and geographical distance to the nearest credit institution affect the degree of credit rationing facing rice farmers. Step 2 of PSM estimator identifies that the amount of capital allocated to inputs such as fertilizer and hired labour increases when credit rationing decreases while that allocated to seed and pesticide is not influenced by credit rationing because rice farmers use these inputs adamantly regardless of effectiveness.
Originality/value
This paper sheds light on the impact of credit rationing on the amount of capital allocated to inputs used by rice farmers, which is largely different from the main focus of the extant literature just on the determinants of credit rationing facing farmers in general and rice farmers in particular.

Abstract
Purpose
Recognition that not every climate adaptation policy is a good one has shifted attention to new tools and methods to measure the adequacy and effectiveness of adaptation policies. This study aims to propose and apply and applies an innovative adaptation policy assessment framework to identify the extent to which climate adaptation policies in Vietnam exhibit conditions that are likely to ensure a sufficient, credible and effective adaptation.
Design/methodology/approach
In total, 21 conditions, categorized under five normative principles and covering critical issue areas in adaptation domain, form the climate adaptation policy assessment framework. The principles were double-checked and tested in case studies through observations and analyses of policy documents to ensure that each condition should be distinct and not overlapping across principles. To see if the principles and attendant conditions were able to capture all relevant aspects of adaptation, the authors used structured expert judgment. In total, 39 policy documents pertaining to climate change adaptation were selected for qualitative document analysis. In-depth interviews with local officials and experts were conducted to address data gaps.
Findings
The study reveals major weaknesses constituting a reasonably worrisome picture of the adaptation policies in Vietnam since several critical conditions were underrepresented. These results shed new light on why some adaptation policies falter or are posing adverse impacts. The findings suggest that a sound policy assessment framework can provide evidence on what effective adaptation policy looks like and how it can be enabled. The framework for climate adaptation policy assessment in this study can be easily adjusted and used for different socio-environmental contexts in which new conditions for policy assessment might emerge.
Social implications
The findings show underlying weaknesses constituting a reasonably worrisome picture of the adaptation regime in Vietnam. In the absence of mechanisms and measures for accountability and transparency in policy processes, adaptation in Vietnam appears more likely to be prone to maladaptation and corruption. While solving these problems will not be easy for Vietnam, the government needs to evaluate whether the short-term gains in sustaining the existing adaptation policies really make progress and serve its long-term climate-adaptive development goals.
Originality/value
Although interpretations of adaptation effectiveness may be very divergent in different normative views on adaptation outcomes, the authors argue that a common, agreed-upon effectiveness can be reached if it is clearly defined and measurable in adaptation policies. Thus, the climate adaptation policy assessment framework proposed in this study is critical for policymakers, practitioners, donors and stakeholders dealing with adaptation to better understand the weaknesses in policymaking processes, pinpoint priority areas of action and timely prevent or prepare for possible adverse impacts of policies.

Abstract
Purpose
The purpose of this paper is to employ the computable general equilibrium (CGE) approach to examine how the European–Vietnam Free Trade Agreement (EVFTA) impacts on the Vietnamese economy in the case of the removal of industrial tariffs.
Design/methodology/approach
The authors construct a social accounting matrix based on the latest data of the Vietnam input-output Table for the year 2012 and then apply the CGE model to simulate the economic scenarios when the tariff rate of the industrial sector reduces to 0 percent.
Findings
The first simulation results demonstrate that the elimination of tariffs in the industrial sector will lead to a 9.13 percent increase in household consumption, together with an increase in the factors of production of the agricultural, industrial and service sectors by 9.61, 9.74 and 8.21 percent, respectively. The EVFTA also causes a deficit in the trade balance because the value of imports increases by 12.54 percent, while exports’ value slightly increases by 2.71 percent. Furthermore, there has been a drop of 2.29 percent in the total government income; nevertheless, social welfare witnesses a gain of 9.13 percent. The second scenario simulation draws crucial attention to policymakers that a small fluctuation in the production tax rate will cause a significant change in the economy.
Practical implications
The reduction of tariff in the industrial sector will increase the social welfare and strengthen the whole economy regarding the growth of household consumption, factors of production and trade value. On the unfavorable side, the EVFTA causes a national budget deficit and puts pressure on domestic production. This paper is a valuable reference for governments and policymakers when they decide to reduce tariffs or adjust production taxes once Vietnam integrates into the world economy.
Originality/value
This study differs from previous research works by utilizing a static CGE model to investigate the impact of removing the industrial tariff on the economy under EVFTA.

Abstract
Purpose
This study aims to investigate the relationship between academic motivations and the risk of Not in Employment, Education or Training (NEET) among university undergraduates and Vocational Education and Training (VET) undergraduates.
Design/methodology/approach
The sample included 402 Vietnamese university undergraduates and 250 VET undergraduates in the southern region of Vietnam. Students took part in a survey, with all participants being informed about the study’s purpose and assured that their involvement was entirely voluntary. In addition to descriptive statistics, the study employed linear regression in SPSS to examine hypotheses.
Findings
The findings indicate that, for university students, intrinsic motivation and mastery approach motivation are associated with reduced NEET risk, while performance avoidance motivation is positively linked to this tendency. In contrast, for VET students, extrinsic motivation and performance approach motivation are negatively associated with NEET risk, but mastery approach motivation may exacerbate the risk.
Originality/value
Grounded in the principles of Self-Determination Theory (SDT) and Achievement Goal Theory (AGT), the study proposes that university students may prioritize competence improvement, knowledge acquisition and the satisfaction of their learning interests, which they believe will help them acquire valuable knowledge beneficial for their future careers. Conversely, VET students emphasize performance and external achievement, which may enhance their outcome and reduce NEET risk. These findings offer significant theoretical and practical insights into the adoption of SDT and AGT and also provide educators or policymakers with more detailed information regarding university and VET students’ learning and development.

Abstract
Purpose
This study aims to examine the premature deindustrialization risk in Vietnam.
Design/methodology/approach
This study uses a manufacturing–income relationship to conduct an empirical estimation. The latecomer index is adopted in the regression model to identify a downward shift of latecomer's relationship.
Findings
The empirical analysis indicates that there is a risk of premature deindustrialization in the Northern Midlands and Mountain Areas. The provinces with low trade openness or foreign direct investment may experience risk of premature deindustrialization.
Practical implications
This study proposes technology diffusion as a policy direction to prevent premature deindustrialization. Furthermore, the Vietnamese government should improve the business environment in the Northern Midlands and Mountain Areas by promoting and attracting export-oriented foreign direct investment.
Originality/value
This study is the first to examine premature deindustrialization in Vietnam based on provincial-level data.

Abstract
How prevalent is COVID-19 in Southeast Asia (SEA), and when will the region open its doors to foreign visitors? Following more than a year of global travel restrictions, these are the major concerns of potential visitors. The article examines border relations in SEA in the face of border restrictions during the COVID-19 pandemic. By 2020, the region had been successful in sustaining low COVID-19 rates. This began to change with the emergence of the delta strain, which forced numerous countries in the region to deal with large outbreaks. For this paper, we relied heavily on secondary data, including the most recent relevant literature and credible and reliable publications from reputable organizations, to ensure the data sources' validity, reliability, and quality.

Abstract
Purpose
In recent years, agricultural activities in the Mekong Delta have frequently faced the potential risks of drought, saline intrusion and unusually heavy rainfall because of climate change, leading to a decline in crop yield. Therefore, this study aimed to establish rice planting seasons in An Giang, an upper-located province in the Mekong Delta.
Design/methodology/approach
The impacts of seasonal variation on the key rice seasons were simulated using the Food and Agriculture Organization-crop model for the OM6976 rice variety grown in the study area. For the simulation, the model combined crop, soil, weather and crop management data.
Findings
The results show that seasonal variation because of changes in weather factors leads to alternation in crop yields across the study area. Specifically, the spring and summer rice planting seasons are advanced by one to two weeks compared with the baseline, and crop yield increased by 5.9% and 4.2%, respectively. Additionally, planting for the autumn–winter rice season on 3 August increased crop yield by up to 8.1%.
Originality/value
In general, rice planting seasons that account for weather factor changes effectively reduce production costs and optimise production.
