We simulate the impact of actual food price increase between June 2006 and June 2008 on poverty across different areas and whether the household’s main income source is agricultural activities. We explicitly treat heterogeneity in food price changes and the patterns of consumption and production by merging a expenditure survey dataset and a price dataset at the provincial level or lower. While the increase of head count index is larger for non-agricultural households than agricultural households, the opposite is true for the poverty gap and poverty severity measures, because poor agricultural households are particularly vulnerable to food inflation.
