Economic analysis of the food system and food safety in aging society with fewer children

这项研究调查了一般食品系统，包括消费需求、农业生产和国际贸易，特别是出生率下降、人口老龄化和食品安全。将线性近似二次近理想需求系统应用于49个城市12个食品类的伪面板数据，该系统在单位标度下是闭合的，即使有额外的回归变量，并且在支出变化上比流行的线性近似几乎理想需求系统更灵活。其他分析包括农业生产的计量经济分析和国际贸易的应用微观经济分析。

This study investigates the general food system including consumer demand, agricultural production, and international trade, with special reference to the falling birth rate, aging population, and food safety. The linear approximate quadratic almost ideal demand system, which is closed under unit scaling even with additional regressors in it and is more flexible in expenditure variations than the popular linear approximate almost ideal demand system, is applied to pseudo panel data per household on 12 food groups in 49 cities for the period January 2000 through December 2008. Other analyses include econometric analysis of agricultural production and applied microeconomic analysis of international trade.
