Zadeh Faculty of Agricultural Economics and Development, University of Tehran Journal Article 2011 04 20 AbstractThis correlational-survery research was conducted with the main objective of investigating viewpoints of farmers of Markazi district of Karaj towards participation in community supported agriculture. The statistical population of the study consisted of farmers in Markazi district of Karaj (N=1598) out of which 117 people were selected as sample using Cochran Formula. In order to enhance the representativeness of the sample, finally the sample size was increased upto 130 farmers. simple random sampling was apllied for the study. The tool of study was a questionnaire which was validated by getting judgment of some experts (faculty members of the Department of agricultural Extension and Education in the university of Tehran). In order to estimate the reliability of the different scales of the questionnaire, Cronbach Alpha coefficient was used. The values ranged from 0.7 to 0.9 which indicated that the tool of study was reliable. The data were analyzed by SPSS-Win. The findings showed that the main motivation of the farmers for participation in community-supported agriculture was to securing financial sources and marketing of their produces. The results of correlation analysis revealed that there were significant positive relationships between the level of interest to receive citizen's financial support with the variables viz., annual income, family labor use and the numbers of citizens' visits to farms at 1 percent level. The same variable was significantly and positively correlated with dependency to residential area and educational level at 5 % level. In addition, the results of Kruskal Wallis test indicated that there were significance differences among different categories of farmers from various residential areas in terms of interest to receive citizen's financial support and tendency to cooperate with citizens of diverse income level, satisfaction level of farming income and the length of plantation at 5 % level.

Sabouhi Agricultural Economics Department, Faculty of Agricultural, University of Zabol 0000-0002-0454-0368 Journal Article 2011 04 20 AbstractIn current study, an irrigation examination and acquisition of environmental water in Kor-river fields, that is dominated from Doroudzan dam to Bakhtegan Lake, was done by an integrated economy-environmental model. The model was considered by economic, hydrologic and agronomic components. In the economic component, an optimal harvesting of water was done using non-linear programming in two scenarios; with and without environmental water constraint. Solutions from simulation of environmental data in the hydrologic component, was used as initial data in the economic component. In the agronomic component, actual crop yield in wet, normal and dry years was determined using the relationship between crop yield and irrigation water amount. Results showed that, the current allocation pattern of surface water in wet, normal and dry years in Kor-river basin is different from the optimal pattern. Water pricing without considering demand and supply and the absence of water markets in the region can be the causes of this difference. Additionally, optimal cropping pattern of the region was determined by the model that can be taken into account for preservation of surface water resources.

In this research the marketing margin and the marketing efficiency of poultry market in different level of the market in Karaj was calculated. The results showed that slaughter houses gain the main part of marketing margin and marking profit. The share of slaughter house was more that 50 percent. The results also indicated that the share of producers from marketing profit was less than 10 percent. Whereas the ratio of producer price to consumer price was 68 percent. This implies that the production cost is relatively high. Market efficiency was also computed and it was less than one. This means that chicken meat market is operating inefficiently. It was suggested that some policy issues should be taken to improve market efficiency. Abstract The main aim of the paper is to determine the marketing efficiency of poultry industry in Karaj.

The minimization of changes in dead weight loss function is used in this study. By using boot strop method and on base of normal distribution for supply elasticity and demand elasticity, statistical properties of optimum combination of the policy instruments and the welfare outcomes were analyzed. The results of the welfare outcomes in wheat market show that government protects consumers more than producers by using consumption subsidy and guarantee price simultaneously. The optimizations of governments’ policy in wheat market reduce governments’ cost and dead weight loss by reduction in protection from consumers. Results also show that per capita consumption and the share of bread in food cost of families change considerably after using optimum combination policy instruments and the effect of using optimum combination policy instruments on the share of bread in food cost of rural families is more than urban families and for low income classes is more than high income classes.

Productivity promotion and bridging the gap between actual and potential production can lead to control of agricultural prices.JEL classification: C22-E2-E3 Productivity shocks Vector Error Correction Hodrick Prescott Filter Kalman filter Production Gap https://jead.um.ac.ir/article_27340_6e1bee0c59ef09e191d26ade686dacf8.pdf

Motameni Department of Industrial Management, Faculty of Management and Accounting, Shahid Beheshti University of Tehran H. Moradi Faculty of Management and Economics, Semnan University M. Moradi Faculty of Agriculture, Tabriz University Journal Article 2011 04 20 AbstractAwareness of consumer reasons during nutrition choice is very important, because this decision directly affect their health. Since beef is one of the essential goods in consumer basket of goods of Iranian households, Exploring of factors that influence consumers purchase decisions and intentions toward imported frozen beefs in East Azerbaijan province – Tabriz city is the purpose of this survey. Present research through identifying affective factors in two categories surveying internal and external factor at conceptual model. Consumers’ viewpoints were collected using probability cluster sampling. Proposed hypotheses are tested using structural equation modeling. Results show that external factor has direct and significant influence on consumer perceived quality; also consumer perceived value effect on purchase intention are positive and significant. Factors prioritizing result show importance of slaughter type, price and regarding of sanitary standards, and country of manufacture didn’t gain needed supports.

Monjezi f Agricultural Economic, Islamic Azad University, Scince and Research Branch Khoozestan S. Ghobadi Islamic Azad University of Ahwaz S.M. Afghah Department of Agricultural Economics, Shahid Chamran University of Ahwaz Journal Article 2011 04 20 AbstractThe Present research accomplished to determination of the trade liberalization effects on Import function of Iran’s wheat crop using time series data from 1357 to 1387 that earn from sources such as agricultural and aerology statistics annual letter, customhouse and Iran central bank website.In this investigation, at first, wheat liberalization index was measured by using Level of International Trade (LIT) and then the effects of LIT was evaluated on mentioned function.In order to checking short run and long run relations between function variables, utilize from Auto Regressive Distributed Lag (ARDL) and method of Error Correction Model (ECM).The estimate of wheat import demand function shows that when trade liberalization occurred, demand for import increased; This increase in long run is more than in short run. Technology advance cause decrease in wheat import request in both long run and short run.
