Role of Economic Ties in Group Loan Repayment: Impact of Agricultural Cooperatives with Field Experiments

上一财年，我完成了自己的研究目标，取得了论文发表2篇、国际会议1次、获奖2次（HIRAKU 3MT竞赛亚军）等多项研究成果。我的研究成果的简要总结如下：[1]第一个研究目标是考察小额信贷对少数民族家庭福利的影响。我在越南北坎省进行了一项调查，收集了289个少数民族家庭的数据。我发现小额信贷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效应。这项研究发表在《发展研究进展》杂志上第二个研究目的是通过实验考察50%价格补贴和信息处理对农民使用有机肥的影响。该实验涉及越南泰阮省的1287名小规模茶农。我的研究结果表明，信息处理可以替代补贴，提高农民的亲环境生产。这项研究在2019年欧空局北美会议上发表第三个研究目标是量化土地保有权安全（LTS）意识对农业投资的因果效应。我使用了来自越南资源获取户调查的面板数据。我的研究结果强调了LTS意识对农民土壤肥力投资的积极影响，支持促进可持续农业。该研究被《土地使用政策》杂志接受发表。

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.
