The aim of the present study is to measurement and analysis of food price inflation due to implementation of Targeted Subsidy Reform program on urban households in Sistan and Baluchestan province. For this purpose, firstly to evaluate composition and changes in household consumption basket Engel functions for food and non-food items in years 2009 and 2012 were estimated. In the next step Quadratic Almost Ideal Demand System (QUAIDS) for all food groups in mentioned years was estimated, Then, Compensating Variation (CV) criterion was computed to measuring the consumer’s welfare changes based on Taylor series expansion method and using the results from the estimated QUAIDS model. Income elasticities of Engel Functions showed that after the implementation of Targeted Subsidy Reform program by the end of 2012, none of the food and non-food products consumption status has not changed. The results of the CV computing indicated that in this period, the urban Sistan and Baluchestan households on average were lost 11,008,222 Rials of their income due to rising food prices after the implementation of the first phase of Targeted Subsidy Reform program. This amount is equivalent to 61.73 percent of the food budget and 19.94 percent of their total income.

Address to increasing demand for wood products and limited domestic resources, wood and wood products imports as one of the easily available and widespread ways in international context, is very important. Among the policy on the imported wood market that is evident, apply a tariff and non-tariff barriers. Know the reaction importers against the change priced is important to be determined and applied or reduction of these barriers. The objective of this paper is an empirical investigation of the QUAIDS for unprocessed, half-processed and processed wood imports and unprocessed domestic wood during 1982-2011. Also we calculate the Compensating Variation cause by reduction in tariffs. The results of study shows a substitution relation between imported woods and substitution relation between domestic and imported unprocessed wood as well as complementary relation between domestic unprocessed wood and imported half-processed wood and processed wood. Also Compensating Variation index shows by tariff reduction, change in Appliers expenditure for half-processed wood is higher than those of two others groups. Due to the use of the excessive harvesting of forests and assist tariff reduction to reduce the pressure on domestic forests, is recommended to reduce the tariffs based on temporal plan. This temporal plan is necessary be considered the possibility of compliance related industries. Also the tariff reduction according to requirements of WTO is important which IRAN is trying to join the organization. Thus it is proposed that the wood products as a whole to be managed by the same administrative system expecting to take into consideration the whole of wood market.

The objective of the study is to measure welfare effects of food price on Iranian urban households within 10 income deciles between 2009 and 2012. Food consumption behavior in Iran is analyzed by estimating a complete food demand system using Quadratic Almost Ideal Demand System (QUAIDS) with considering homogeneity and symmetric conditionsfor 9 major food groups for each income deciles.The elasticity coefficients derived from QUAIDS were used to evaluate the distributional impacts of the relative food price changes in terms of Compensated Variations (CV). Based on our estimates, the food groups of cereals, dairy products, vegetable and pulses, Potables and Spices are necessary goods, as their budget elasticity is positive and below one at the same time. Meat, edible oils, fruits and dried fruits and Sugary products are luxury goods, with income elasticity above one. Results showed that all urban households groups, suffered welfare loses from rise in the food prices during 2009 and 2012. In addition for households in the lower deciles need the greatest relative amount of new income to return to pre-reform consumption levels and, indeed, this amount declines monotonically as household expenditures increase. Also the relative loss of poorest urban households is about threefold than the loss of richest households, which demonstrates the vulnerability of these households to food price increases. Consequently, it is essential that the policy makers support the poor households.

Pisciculture, especially in countries which are unable to develop their marine resources, is a desired to provide part of their food and protein needs. This study aims at investigating welfare impacts of energy subsidy removal on fish producers in Fars province. To achieve the objective, cross-sectional data obtained from fish producers of Fars Province in 2010 was used. Cost, input demand and production functions were estimated using the collected data. The findings showed that in Fars Province removing fuel subsidies is led to decreased demand for fuel and production as well as a reduction in producer's revenue. As a result of that, in Fars Province benefits from fish are reduced by0.16 percent. The results also showed that food is the most important input in the fish production.a10 percent increases in food consumption is expected to raise the fish production by 4.8 percent. On the other hand, a 50 percent increase in the energy price will reduce the energy consumption by 9.5 percent, and as a result of that, the production and the benefit will be reduced by 0.057% (0.036 tons) and 0.06%, respectively. Regarding the importance of food in production, it is suggested to focus on improving the food productivity.

Maize production accounts for the agricultural economic pivot of Fars province and any fluctuation in its production is expected to influence the household welfare. The chemical inputs are highly important in increment of agricultural products and especially in maize production increment. Regarding the necessity of optimal use of the inputs in production, in order to decrease farmers production costs as well as to saving the subsidies, this study attempts to analysis the welfare impacts of fertilizer subsidy elimination in maize production in Fars province (as the maize pivot). To get the objective of study cross section data set obtained throughout the Fras province selected farmers in 1387-88 were applied. Then profit, inputs demand and production functions were estimated and some analysis was developed. The results showed that fertilizer subsidy elimination results in increase in production cost and lower profit about 24.88 and 15.55 respectively since the fertilizer demand is inelastic with respect to its price changes. This means that price polices are not able to develop a solution to optimize the input use and complementary and compensatory polices are needed.
