Soil fertility conservation has become an increasing concern in Vietnamese agriculture owing to excessive use of agrochemicals. The use of organic fertilizers is considered an environment-friendly practice for sustainable agriculture. Although environmental awareness has emerged and production technologies of organic fertilizers have been introduced in recent years, their adoption remains limited among farming households. This study focuses on the causal effects of information acquisition on the use of organic fertilizers from agricultural extension services and from peers of farming households. The estimation results show that land size, land tenure, educational level, family labor endowment, and household wealth are significantly associated with the likelihood of using organic fertilizers. Information acquisition through both information sources positively affects the use of organic fertilizers. However, information acquisition from agricultural extension services has a greater marginal impact than that from peers. Despite its lower influence, information acquisition from peers plays a supplemental role in incentivizing farming households to use organic fertilizers as an environmentfriendly agricultural practice among rural communities in Vietnam.

This study explores factors associated with people’s willingness-to-pay (WTP) for family-based health insurance covering the whole family in central Vietnam. The amount of WTP was elicited by using a contingent value method in 2014 and the mean WTP was 2.27 percent of GDP per capita. Firstly, our study reveals that even the poor are willing to pay towards obtaining health insurance. Secondly, our regression analysis shows that the health insurance status of the household head, in addition to education, wealth level, and family size, is associated with WTP. Furthermore, our estimation results with restricted sample households whose designated health facility is the commune health station (CHS) confirm that healthcare service quality measures designed based on patients’ past experiences at the CHS are significant predictors of WTP as they can affect people’s valuation of the benefit of the health insurance.

To achieve the Sustainable Development Goals, particularly to promote healthy living and well-being for all ages, we must ensure a high quality of healthcare services at primary facilities. However, the shortage of healthcare workers in primary facilities is a problem in many countries, including Vietnam. Despite concerns about the low job satisfaction of health workers and value of altruism in this field, no existing research has thus far addressed its effect on job satisfaction. This study thus contributes to the body of knowledge on healthcare workers’ job satisfaction by observing the role of altruism.We conducted a quantitative analysis by using data collected from healthcare workers employed at primary facilities in central Vietnam in 2014. The survey administered to healthcare workers (n=241) included a hypothetical dictator game questionnaire to elicit their level of altruism. We then used an ordered probit model to examine the factors associated with healthcare workers’ job satisfaction, focusing particularly on altruism by controlling for both individual-level attributes and the condition of their workplaces.We found that a higher level of altruism is associated with lower job satisfaction. Further analysis revealed that more altruistic workers are also likely to have a stricter self-evaluation of healthcare quality, including the availability of drugs. Altruistic healthcare workers may be frustrated when working in environments in which resources are constrained and workers cannot perform to their full ability despite a wish to help others.

We evaluate the impact of agricultural credit program participation on children's school attendance in rural Malawi. Our paired-site sampling survey reveals that credit uptake decreased school attendance by young girl children. This finding raises concerns that young girl children are exploited as child labor, either at home or in the field, when working adults become more involved in income-generating activities financed by credit. The data, however, do not show clear evidence for young girls staying at home to do household chores or working in the fields in households that obtained credit, but instead find simultaneous occurrence between attending school and taking responsibilities for domestic chores by young children. It would appear, therefore, that credit uptake delays the realization of this concurrence among young girl children and leads to delayed school enrollment. (C) 2009 Elsevier Ltd. All rights reserved.

The introduction of health insurance has been one of the most important policy agenda in a growing number of newly emerging economies. This research project, in Vietnam where the government has exerted enormous efforts towards universal health insurance coverage, aims to implement empirical studies to draw valuable lessons for Vietnam and also other counties in the process of achieving universal health insurance coverage. During this research project, we analyzed statistical data obtained from several governmental organizations such as the General Statistics Office and the Ministry of Health of Vietnam as well as data collected by conducting our original household and health facility surveys in central Vietnam. The findings from our empirical analyses were presented at both domestic and international symposiums, seminars and workshops (16 presentations). In addition 6 academic papers have been published.
Under this research project, the following papers were written. First, one paper investigated the mechanism under which orphans in sub-Saharan Africa lagged behind in educational progression. Second, other two papers examined whether participation in microcredit programs in Malawi had a positive impact on child schooling, and also enhanced farmer’s coping abilities against risk. Another paper was written for the purpose of evaluating the impacts of microfinance programs in rural India.In addition, some other papers by using the data set collected in Indonesia tried to draw implications of infrastructure provision, particular irrigation and rural roads, for economic growth. All these papers aimed at making some policy suggestions for poverty alleviation.
本研究は、2015年に国連で採択されたSustainable Development Goals(SDGs)の第3重要課題に設定された「健康な暮らし及び厚生の促進」に関連した研究課題に対して、既存データならびに現地調査を通して収集する独自データを用いて取り組むことを目的としている。2020年度は、これまでに実施してきたベトナムにおける医療保険制度の変遷とその加入率の変化に関する研究を財務省財務総合政策研究所ASEANワークショップにて発表する機会を得ている。近年、急速な経済成長を遂げているASEAN諸国の筆頭であるベトナムにおける保健医療制度に対しては益々関心が高まっている。本ワークショップは有益な情報共有の場となった。ワークショップでは、ベトナムの近年の経済状況の概観から始まり、経済成長と共にどのように国民の健康状態が改善してきたかを示した。その後、ベトナムにおける医療サービスの提供体制(公的医療施設は中央レベル、省レベル、郡レベル、村落レベルの4階層の構造をしている)を示した上で、2020年度までの国民皆保険化を目指して、これまでにどのように医療保険制度が変遷してきたかを示し、1)皆保険化を妨げる要因は何か?2)全国での加入率が8割を越えるなかで医療保険市場の「情報の非対称性」の問題はいつまで残るのか?3)医療保険加入率の増加に伴い医療サービスの需要と供給はどのように変化してきたのか?4)医療保険の加入と企業利益や労働生産性の間にはどのような関係があるのか?について研究発表を行った。なお、本ワークショップでは、ベトナム政府がいかに新型コロナウィルス感染症の拡大を防ぐことができたかについても、特にベトナム政府の初動の速さに注目した発表を行った。そして、1)と2)をまとめた論文については国際開発学会の企画セッションでも発表を行っている。
The objective of this research is to make a new methodological proposal for program evaluation and policy simulation to examine the financial sustainability of the public health insurance system in Vietnam. This research implemented some field experiments regarding dissemination of sustainable agricultural practices utilizing previously wasted local resources to improve health conditions of people and ensure the sustainability of the public health insurance system. This research then evaluated the causal effects of the field experiments and tried to link their micro-level impacts to macro-level impacts. During the research period, one paper regarding a new chicken feeding technique was published in the field of natural science. In addition, three papers were published in the field of social science. One paper investigated the dissemination process of sustainable agricultural practices and the other two dealt with policy issues relating to health insurance.
