the objectives of this research were to investigate influences of energy inputs and energy forms on output levels and evaluation of co2 emissions for hazelnut production in guilan province of iran. moreover, the sensitivity analysis was done by marginal physical productivity (mpp) method for energy inputs and energy using linear regression. initial data were collected from 120 orchardists in se...
background determinants of health or health production function in health economics literature constitute noticeable issues in health promotion. this study aimed at estimating a health production function for east mediterranean region (emr) based on the grossman theoretical model. methods this ecological study was performed using the econometric methods. the panel data model was used in order...
The paper develops a theoretical background on the co-production approach as an extension of operations management principles, in which co-production function assumes well-defined functional form with the input presence of both firm and customers. The co-production approach not only views a customer as a co-producer, but also conducts strategic trade-offs between a firm and customers in service...
Nanoemulsion is an alternative and promising approach to overcome insolubility and bioavailability problems of bioactive compounds. In this study, the sonication parameter for preparing nanoemulsions with high α- tocopherol and linolenic acid content were optimized by using response surface methodology and their stability were evaluated during 2 months’ storage. The response surface analysis re...
Intermediate goods are another produced factor of production, like capital. Considering intermediate goods in production function makes multiplier be even larger than the one. In this paper, based on the approach of Jones (2007,2010) We computed multipliers by intermediate goods. For this purpose, we used Input – Output table of Statistical Center of Iran (base year: 2001). Finding show that 10...
Risk and uncertainty have an important role in determining farmers' goals and their decision making. Risk affects optimal use of inputs and production efficiency. Using production inputs especially new inputs is one of the effective factors in production risk hence, it is necessary to obtain information about inputs use risk in order to find solution to risk management. For investigating effect...
due to contiguous city of ravar with lut and dasht-e kavir desert, and weather conditions, water is one of the rarest agricultural inputs in this city. pistachio allocates 90% of garden and 73% of agricultural lands of the city and it is the most important agricultural product in this region. a major source of agricultural water supply in this area is groundwater. low price of water on one side...
This paper probes effects of the evolvement of labor resources on technical efficiency in crop production in rural China. Based on twelve years of data on crop production of 30 provinces in China, a stochastic frontier production function model is used to measure crop production efficiency in three crop-functional areas—the production area, the consumption area, and the balanced area. Then effe...
