Last fiscal year, I achieved my research objectives and had several research achievements, for example, 2 published papers, 1 international conference, and 2 awards (runner up prize at HIRAKU 3MT competition). The brief summary of my research results are presented as below.[1] The first research objective was to examine impacts of microfinance on household welfare of ethnic minorities. I conducted a survey in Bac Kan province, Vietnam to collect data of 289 ethnic minority households. I found positive impacts on total expenditure and educational expenditure, supporting the welfare effects of microfinance on ethnic minorities. This research was published at Progress in Development Studies.[2] The second research objective was to experimentally examine impacts of 50% price subsidy and information treatment on farmers’ adoption of organic fertilizer. The experiment involved 1287 small-scale tea farmers in Thai Nguyen province, Vietnam. My findings suggested the potential of information treatment to be a substitute for the subsidy to enhance farmers’ pro-environmental production. This research was presented at 2019 ESA North America Meeting.[3] The third research objective was to quantify the causal effect of awareness about land tenure security (LTS) on investments in agriculture. I used panel data from Viet Nam Access to Resources Household Survey. My findings highlighted the positive impacts of LTS awareness on farmers’ investments in soil fertility, supporting the promotion of sustainable agriculture. This research was accepted to publish at Land Use Policy.

上个财政年度，我实现了研究目标，并取得了几项研究成就，例如，有2篇发表论文，1个国际会议和2个奖项（在Hiraku 3MT比赛中获得亚军奖）。我的研究结果的简要摘要如下。[1]第一个研究目标是检查小额信贷对少数民族家庭福利的影响。我在越南Bac Kan Province进行了一项调查，以收集289个少数民族家庭的数据。我发现对总支出和教育支出的积极影响，支持小额信贷对少数民族的福利影响。这项研究发表在开发研究进展中。[2]第二个研究目标是实验研究50％的价格补贴和信息处理对农民采用有机肥料的影响。该实验涉及越南泰国尼古恩省的1287个小型茶农。我的发现表明，信息处理的潜力可以替代补贴，以增强农民的亲环境生产。这项研究是在2019年ESA北美会议上提出的。[3]第三个研究目标是量化对土地权限安全（LTS）对商定投资的认识的因果影响。我使用了来自越南访问资源家庭调查的面板数据。我的发现强调了LTS意识对农民对土壤生育的投资的积极影响，支持促进可持续农业。这项研究被接受在土地使用政策上发表。
