20201225日下午, 经济管理研究中心(CEFMS)第79期学术研讨会在水上教学楼210室顺利举行,中南财经政法大学工商管理学院助理教授王萍老师应CEFMS的邀请报告了工作论文“Spatial and Temporal Patterns of Consumption of Animal-source Foods in Tanzania”。王萍老师毕业于奥本大学,其主要研究方向为农业国际贸易、粮食市场与粮食消费、发展经济学,研究成果发表于《Applied Economics》《Marine Resource Economics》等期刊。

该研究旨在探索坦桑尼亚动物源性食品(Animal-source Foods,简称为“ASF”)的家庭消费模式及其地区与动态变化趋势,并采用Quadratic Almost-Ideal Demand System (QUAIDS) 模型估算了多种ASF的需求弹性。具体来说,ASF包括鱼类、牛肉、鸡肉、羊肉、猪肉。利用坦桑尼亚2008-2015年全国面板数据,该研究发现ASF消费在此期间呈稳定增长态势,其消费模式存在明显的地区差异,其中收入及人口背景变量是家庭ASF消费的重要决定因素。此外,研究结果表明不同ASF的价格弹性存在明显差异,其中仅羊肉与猪肉的价格弹性大于1

CEFMS师生就论文模型设定、价格弹性估算结果合理性、家庭人均消费与整体消费的相对重要性、研究极端贫困人口消费问题重要性等诸多问题与王萍老师进行了深入探讨。

 

[Seminar 79 Spotlight] Assistant Professor Ping Wang (Zhongnan University of Economics and Law): Spatial and Temporal Patterns of Consumption of Animal-source Foods in Tanzania

On December 25th, 2020, Center for Economics, Finance and Management Studies (CEFMS) held the 79th seminar in classroom 210, Shuishang Teaching Building. Assistant Professor Ping Wang from Zhongnan University of Economics and Law gave a speech about her working paper, “Spatial and Temporal Patterns of Consumption of Animal-source Foods in Tanzania”. Dr. Ping Wang graduated from Auburn University, and her research field of interests includes agricultural international trade, food market and consumption, and development economics. She has published research on international journals like Applied Economics, Marine Resource Economics.

The paper aims to study the pattern of household level Animal-source Foods (ASFs) consumption in Tanzania, identifying spatial and temporal trends of consumption changes. At the same time, the paper applies the censored Quadratic Almost-Ideal Demand System (QUAIDS) model to estimate price and expenditure elasticities. In particular, the ASFs refers to fish, beef, chicken, lamb and pork. Making use of the Tanzania National Panel Data from 2008-2015, the paper finds that consumption of ASFs has been increasing steadily, and the consumption pattern is spatially different. Income and demographic variables affect the likelihood of household food consumption of fish and meat products. Additionally, the paper suggests there is evident difference in the price elasticities of different ASFs, e.g., only the price elasticities for lamb and pork is higher than 1.

In the Q&A part, faculties and students from CEFMS discussed with Dr. Ping Wang about a series of issues, for example, the importance to zoom in the sample to the extremely poor cohort and the comparative importance of individual level consumption with the household level consumption.
