in the present study, the energetic and economic modeling of lentil and chickpea production in esfahan province of iran was conducted using adaptive neuro-fuzzy inference system (anfis) and linear regression. data were taken by interviewing and visiting of 140 lentil farms and 110 chickpea farms during 2014-2015 production period. the results showed that the yield and total energy consumption w...

the energy efficiency, greenhouse gas (ghg) emissions, and carbon efficiency of paddy rice production were analysed in sari in the mazandaran province of iran during 2011–2012. data was collected through questionnaires and interviews with paddy producers. the results showed that the net energy gain was 27,932 mj ha-1 and energy efficiency was 1.83 during production. the results of the cobb-doug...

The subject of discussion is health care production functions. The parametric two-factor Cobb–Douglas and transcendental logarithmic (translog) production functions are frequently used. However, empirical and theoretical work has often questioned the validity of the parametric Cobb–Douglas and translog as a model for the production of health care. The aim of this study is to propose a new flexi...

The Cobb–Douglas function is today one of the most widely adopted assumptions in economic modeling, yet both its theoretical and empirical bases have long been under question. This paper builds an alternative function on very different (albeit also neoclassical) microfoundations aimed at both addressing those theoretical drawbacks and providing a better empirical fit than the Cobb–Douglas formu...

the current study assessed the climate change impacts on land productivity of major food and non-food grain crops in india. we compiled panel data for 30 years (1980-2009) using fifteen crops across thirteen agriculture intensive states. the value of production for each crop is estimated by farm harvest price (at constant prices, 1993-1994). aggregate value of production on per hectare land is ...

in this study, farm level technical efficiency (te) and its determinants were investigated. a stochastic cobb-douglas (cd) production frontier was used to provide estimates of input-oriented te for a sample of 100 rain fed farms in two palestinian governorates. empirical findings showed that the estimated te of the farms in the pooled sample ranged from 35.7 to 95.6%, with a mean value of 72.2%...

efficiency in agricultural production is indicative of the efficiency level of farm households in their farming activities. farmers in developing countries do not make use of all the potential technological resources, thus making inefficient decisions in their agricultural activities. herein, technical efficiency in relation with the production of three types of rice crop (boro, aus and aman) w...

Standard growth theory implies that steady-state growth in the presence of exponential declines in the prices of computers and other capital equipment requires a Cobb-Douglas production function. Conventional wisdom holds that capital shares are relatively constant, so that the Cobb-Douglas approach might be a good way to model growth. Unfortunately, this conventional wisdom is misguided. Capit...

Although a number of different models have been suggested for the process that brings workers and firms together in the labour market, none of these performs well in empirical studies of the aggregate matching function. Empirically, the most successful functional form is Cobb-Douglas, for which there are no microfoundations in the existing literature. I present a new model for the matching proc...
