The Impact of the Global Food Crisis on Self-Assessed Food Security
基于盖洛普世界民意调查数据，研究了2007-08年全球粮食危机对自评食品安全的影响，发现全球平均指标未恶化，但各国差异显著。
We provide the first large-scale survey-based evidence on the impact of the global food crisis of 2007-08 using an indicator of self-assessed food security from the Gallup World Poll. For the sampled countries as a whole, this subjective indicator of food security remained the same or even improved, seemingly owing to a combination of strong economic growth and limited food inflation in some of the most populous countries, particularly India. However, these favorable global trends mask divergent trends at the national and regional levels, with a number of countries reporting substantial deterioration in food security. The impacts of the global crisis therefore appear to be highly context specific.
