as an industrial crop, sugar beet plays an important role in meeting domestic demand for sugar. given the higher level of imported sugar iniran, the application of protectionist policies is an approach for supplying required sugar. one of these policies is technological improvement. in order to study the effect of this policy, sugar beet supply and demand equations in 1971-2008 were fitted by t...

abstract the aim of this study was to selecting the suitable model for forecast land, production and price of sugar beet in iran. for this purpose, models applied to forecast are arima, single and double exponential smoothing, harmonic, artificial neural network and arch for period 1993-2008. results of durbin-watson tests, land, production and price of sugar beet series were found non stochast...

agricultural prices have a high fluctuation and forecasting may help decision making effectively. the aim of this study was to forecast the nominal and real prices of sugar beet and to recognize the appropriate forecasting model. initially the stationary of the series was tested. in order to investigate whether the series are stochastic, the nonparametric test of vald-wulfowitz and parametric t...

in this paper, productivity of and demand for water throughout eqlid’s sugar beet growers in 1385 were investigated. to address the objective 100 growers were selected using two-stage cluster sampling, then required dataset was obtained by interviewing and completing questionnaire. in order to study factors affecting sugar beet production, cobb-douglas production function was applied. based on ...

abstract marketing 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...

in this study the trend of technological change and its nature was studied in production of sugar beet in iran by using dual approach. this approach is useful for estimating the demand structure of the input price change and technology status. after estimating the various forms of flexible functions, by selection of translog cost function with cost share equations system is estimated using seem...

in this paper price and non- price factors affecting the area of sugar beet cultivation was been studied, using a logarithmic model and a cross sectional data on 195 producers of sugar beet in khorasan province in 2003 producers were selected based on stratified random sampling method. results of study showed that percent of  sugar (an impostor), type of seed, yield of sugar beet in the last ye...
