      abstract = {Although rising food prices have hit hard on a large  number of
households in many developing countries, the  vulnerability in terms of food
security varies across  different household sectors within a country. In this
study  we have developed a simple analytical model and used it to  examine
the food security vulnerability across different  households to a shock in food
prices by using three  commonly-known household sectors (urban, rural,
estate)in  Sri Lanka. In particular, we have estimated the combined  impact of
income and price rises on food security of these  sectors. Our empirical results
suggest that the overall  food security in all three household groups (measured
in  terms of real food consumption above the poverty line food  consumption)
has been marginally decreasing over time in  Sri Lanka. Furthermore, the
negative effect of rising food  prices has been partially offset by the positive
income  effect in all three household sectors. The results also  suggest that the
urban sector is highly vulnerable to a  food price shock than the other two
sectors. The least  vulnerable group is the rural sector, whilst the estate  sector
lies in the middle.},
