Iran has experienced high food prices in recent years. This paper examines the welfare impacts of rising major food groups' prices on Iranian urban households using Quadratic Almost Ideal Demand System (QUAIDS) approach. The elasticity coefficients derived from QUAIDS are used to estimate Compensated Variations (CV).The study uses Iranian Household Expenditure and Income Survey (HEIS) raw data,...

abstract comparison of food prices in different periods, indicates fluctuations and continually upward trend. any change in agricultural sector variables, as main food supplier, will affect food price. productivity shocks and production gap are examples of such variables. in this paper ,hodrick prescott and kalman filters are used as generators of productivity shocks and production gap series. ...

BACKGROUND Targeted food pricing policies may improve population diets. To assess their effects on inequalities, it is important to determine responsiveness to price changes across income levels and ethnic groups.

Food price fluctuations, which will be exacerbated by climate change, make West African food security even more tenuous.

Many studies conclude that the rise in global food prices due to higher demand from the development of biofuels, climate anomalies, and increased of oil prices. Not only the food commodity index rose more than 60 percent, nonfood commodity price index also rose over 60 percent and crude oil price index has increased even further above 60 percent. The purpose of this study is to analyze the impa...
