the aims of this study were to investigate the energy flow and its modeling in shablon cultivar of plum production in golestan province of iran. data were collected through questionnaires and also interviews with producers. cobb-douglass model and sensitivity analysis were used to determine the effects of energy inputs on plum yield. the results revealed that the total energy inputs and energy ...

In this paper we examine whether nonlinearities in the aggregate production function can explain parameter heterogeneity in the Solow (1956) growth regressions. Nonlinearities in the production technology are introduced by replacing the linear Cobb-Douglas specification with the more general CES specification. We justify our choice of production function by showing that in the context of cross-...

Enterprises are investing heavily in cloud data centers to meet the ever surging business demand. Data Center is a facility, which houses computer systems and associated components, such as telecommunications and storage systems. It generally includes power supply equipment, communication connections and cooling equipment. A large data center can use as much electricity as a small town. In toda...

Charles Cobb and Paul Douglas in 1928 used data from the US manufacturing sector for 1899-1922 to introduce what is known today as Cobb-Douglas production function that has been widely economic theory decades. We employ R programming language fit formulas parameters of generated by authors recently via bi-Hamiltonian approach same set utilized Douglas. conclude output elasticities total factor ...

The aim of this research was to study the energy flow and the modelling of energy use in broiler production in the Guilan Province of Iran. The data were gathered through interview with 25 broiler farm managers out of a total of 146 broiler producers in Rasht, the center of Guilan Province, Iran. The effect of broiler farm size at three levels—small (˂20,000 birds), medium (20,000–30,000 birds)...

Production is the most fundamental activity in our economy. In this paper, a Cobb-Douglas production function is used as the mathematical model to describe the relationship among production, labor and capital. Two reliable production optimal control problems are studied. Algorithms to find dynamic optimal control intervals are provided with interval parameter presentations and interval computat...

Many growth models assume that aggregate output is generated by a Cobb-Douglas production function. In this article we question the empirical relevance of this specification. We use a panel of 82 countries over a 28-year period to estimate a general constant-elasticity-of-substitution (CES) production function specification. We find that for the entire sample of countries we can reject the Cobb...

In this paper we consider the specification and estimation of the Cobb-Douglas production function model. After reviewing the "traditional" specifying assumptions for the model which are based on deterministic profit maximization, we develop a model in which profits are stochastic and in which maximization of the mathematical expectation of profits is posited. "Sampling theory" and Bayesian est...
