题目：FDA拒绝进口我国农产品的贸易保护动机探究——基于面板结构VAR的分析。

主讲人：茅锐副教授

时间与地点：4月26日（周五）14：00-16：00，浙江大学紫金港校区启真大厦1213

摘要：本文从技术性贸易措施的实际执行水平出发，整合行业层面下中美农产品贸易数据、美国进口拒绝及就业数据，运用面板结构化向量自回归模型对2002-2017年间影响美国对中国出口农产品边境执行力度的因素进行了探究。结果表明，在面临相同的进口数量和产品质量时，美国国内就业减少将导致中短期内拒绝数量增加，尤其体现在金融危机后及非抽检拒绝数的增加，表明具有较大自由裁量空间的进口监管已成为美国实施贸易保护的一种手段。与此同时，产品的历史风险水平、进口冲击规模和质量竞争程度也影响了美国的拒绝决策。相比于整体经济，单个产业的特异性冲击是导致产品拒绝数增加的主要组分；在不同产业中，进口拒绝的形成机制和演变特征存在明显差异。基于本文的研究结果，我国在应对美国隐性贸易保护措施时应充分考虑不同产业的异质性，在改善出口农产品质量安全水平、积极应对贸易壁垒的同时，也应密切关注国外重点敏感产业经济形势，做好预判预警工作。

题目：The Number and Gender of Children and Rural Parents’ Health: Evidence from China

主讲人：李梦华博士生

时间与地点：4月26日（周五）14：00-16：00，浙江大学紫金港校区启真大厦1213

摘要：Middle-aged and elderly people in China are vulnerable groups in terms of physical health. Their health status is not easily affected by individual characteristics, self-behavior, chronic diseases and intergenerational support, and socio-economic environment, etc.This paper presents a new analysis of the China Health and Pension Tracking Survey (CHARLS) data in 2015 that indicates the Chinese parents’ health are causally linked to the number and gender of children. We confirm that “more children more blessings” in China, as the number of children rises, Chinese parents are healthier. But “nurturing boys to prevent elder” is not been found. Chinese parents with a son are significantly unhealthier than those with a daughter, especially when children at marriage and childbirth stage.

题目：Farmers’ Preferences for Attributes of Rice Varieties: Implication for Improved Variety Development

主讲人：Bashiru Mansaray, PhD student

摘要：Farmers’ preferences and needs have been shown to be crucial in improving the development of rice. However, research on farmers’ preferences for crop attributes is scarce in Africa. This study intends to bridge this gap by focusing on farmers’ preferences for rice variety attributes based on a nation-wide survey conducted in Sierra Leone. Results from a Best-Worst Scaling analysis revealed that potential yield, maturity, pest and disease resistance, and seed longevity, are the four most-preferred attributes of a rice variety, while the least preferred attributes are ease of threshing, fertilizer response and shattering. After applying a latent class model, farmers were found to align with six distinct classes: majority farmers, price-sensitive, conservationist farmer, rational farmer, maximum output, and subsistence. These segments showed differences in terms of the farmers’ characteristics (e.g. gender, education, income, farm farming experience, and farmland size) and in the importance given to extrinsic factors (e.g. access to market, extension services, and membership to farmers’ organizations). Among these classes, the majority farmers are more likely to have relatively more farmland, easier access to other farm resources (e.g. chemical fertilizers and market information) and are more likely to prefer potential yield. The price-sensitive class places high importance on seed price and consists of farmers who are low-income, have better access to extension services and membership to farming organizations. Furthermore, preferences are distinct for conservationist farmers who have environmental and sustenance concerns.

题目：Risk aversion and pesticides use decision of vegetable farmers in rural Pakistan

主讲人：Mohammad sohailNazar, PhD student

摘要：The high pesticides residues in the vegetables, primarily due to excessive pesticides use, is a major challenge facing the consumer's health and international trade in Pakistan. This study use survey data of 360 tomato farmers from rural Pakistan to study the impact of risk aversion and various socio demographic factors on the pesticides use decisions of the farmers. The ordinary Least square (OLS) model to measure the impact of risk aversion and demographic factors on the pesticides use have been employed. We find pesticides overuse is significantly influenced by the farmer's selection of the marketing channels, whole sale and local markets compared to the dealers, and farmer's perception of the appearance of the vegetables. Moreover, marital status, pesticides price, discourage pesticide use in a statistically significant manner. The risk aversion significantly increased the vegetable farmers 'pesticide use. These findings imply risk mitigation strategies like agricultural insurance may encourage farmers to use the judicious amounts of the pesticides, thus reduction in the pesticides use and improving the food safety situation of the fresh produce in Pakistan.
