AbstractResearches of preservation valuation of natural resources and environment were done in order to create necessary awareness for making optimal decisions in the field of the ways of economic management of these resources and helping to establish sustainable regional development strategy. In this study, preservation value of Lilium ledebourii estimated using single bounded dichotomous choice contingent valuation method. Required data were obtained through face to face survey and gathered from 177 respondents. Results showed that respondent’s willingness to pay is equal to 6540.33 Rials annually using linear functional form and 9675.22 Rials annually for logarithmic functional form. Also, comparing confidence intervals of estimated willingness to pays showed that the estimated WTP using linear model is more precise. Present study can provide proper framework for precise estimation of preservation value through applying different functional forms and precise estimation of WTP, so the estimated WTP shows the importance of preservation of distinct plant varieties. It’s proposed that economic researchers to calculate the level of the significance of WTP in addition to using several functional forms in contingent valuation method. Also, it is proposed to policymakers that it is necessary to pay attention to society’s participation in preserving environment in addition to annual government budget.

AbstractPresent study used Translog cost function for determining break point of paddy farms. Requested data set include inputs’ prices and quantities, and production amounts had been acquired from 500 rice farmers of Guilan province at 2009. Model used in this study is seemingly unrelated regressions (SUR). The results showed that labor and pesticides had the highest and lowest share of production costs, respectively. Accordingly, increasing labor wages puts the greatest effect on rice prices. Estimated returns to scale measure (ES) showed that there are increasing returns to scale in investigated paddy farms. Accordingly, splitting paddy farm will increase the cost of rice production and by increasing price of rice competitiveness of farmers reduced in compare with foreign competitors. Present study showed that the break point of paddy farms was one hectare so farms less than one hectare will increase average production costs, significantly. A policy recommendation is that paddy farms less than one hectare should be integrated.

AbstractSuccessful presence of Indian and Pakistani rice in Iran’s market due to having similar quality with the domestic rice, extensive advertisement, and good packaging has faced rice production in Iran with a big challenge. Assuming that the attractions of Iranian consumers toward these imported rice varieties are a signal of changes in the preferences of the domestic consumers in favor of the imported rice and a kind of loyalty establishment towards these products, then the continuity of production of rice in Iran might be under serious question. The present study investigates this issue. It tries to test the structural break in preferences of rice consumption in Iran. To this end, the nonparametric WARP approach together with K-W statistical test are applied to time series data over 1990-2007. Results of WARP formation show a sort of structural changes in consumer preference in 1999. However, results of K-W test revealed that this change in the preferences is not a permanent structural change but is a temporary change due to a kind of nonlinear transitory shocks in the rice market in Iran. The stability of Iranian preferences towards domestic rice leads to the conclusion that the Iranian producers can use this opportunity and reestablish the position of the Iranian rice in the market by improving their competitiveness through improving the quality, advancing productivity and reducing the cost of production.

AbstractMarketing element’s contrastive behaviors toward price risk had considerable effect on marketing margin in a way that transferring increase in price to final consumer, reduces purchasing power and so consumption amounts of consumers. Present study evaluated effective parameters on marketing margin in 2 level of ranch-processing and processing- retail of beef and lamb with consideration of risk effect and risky behavior and also demand and supply sides variables from 1997 - 2003. The Results revealed that, Also, elasticity of price risk variable (price fluctuation) in slaughterhouse and retail levels respect to farm-slaughterhouse and slaughterhouse-retail marketing margin for beef, equal to 0.51 and 1.78, respectively and for lamb obtained 0.03 and 0.54.
