sugar beet is an important crop from the point of production and consumption. in this case, fars province is one of the largest producers iniran. the purpose of this study was to determine the effective factors on sugar beet supply. accordingly, time series information of the crop was collected from 1990 to 2004 infarsprovince and were analyzed through nerlove partially adjustment model that is...

Regional output per worker has converged across Chinese provinces in 19791989. The estimated rate of convergence is 2.2 percent. This rate of convergence can be explained by neoclassical growth model conditional on assumptions about factor mobility and production elasticities. My empirical results show that capital mobility has been high across Chinese provinces and that the production elastici...

having observed the costly failures of different cutoff walls, that had been constructed according to the mix design specified by reputable consultants in iran, a research programme was conducted to study the effects of constituent materials on the properties of plastic concrete. the main properties, such as compressive strength, biaxial and triaxial strains, permeability, and modulus of elasti...

While numerous studies assess the impact of healthcare spending on health outcomes, typically reporting multiple estimates of the elasticity of health outcomes (most often measured by a mortality rate or life expectancy) with respect to healthcare spending, the extent to which study attributes influence these elasticity estimates is unclear. Accordingly, we utilize a meta-data set (consisting o...

the effects of cutting subsidy on broiler production in kerman province were investigated after privitization. in this regard a random sample of 32 poultry farms in kerman were chosen and the farmers were interviewed. the unit- output - price profit function model was used to determine the supply and demand elasticity of broider products. the results show that the profit of poultry farms increa...

due to the being in the desert bar and ecosystem sensitivity to water , water management in the agricultural sector of the iran is one of the priorities of managers and planners of this section. therefore accurate modeling of the production function, for policies to increase efficiency and reduce the use of inputs, as well as forecasts for the timely supply with low cost, is of utmost importanc...

Normalising CES production functions in the calibration of basic dynamic models allows to choose technology parameters in an economically plausible way. When variations in the elasticity of substitution are considered, normalisation is necessary in order to exclude arbitrary effects. As an illustration, the effect of the elasticity of substitution on the speed of convergence in the Ramsey model...

In this section, I will apply plant-level input price variation and materials usage to provide an alternate set of estimates of εQ. To do so, I pursue the following two-part strategy. For each industry, I estimate how easily individual plants substitute across their factors of production, by relating plants’ materials purchases to their materials prices. Then, I apply the methods developed in O...
