In many applications, discrimination among decision making units (DMUs) is a problematic technical task procedure to decision makers in data envelopment analysis (DEA). The DEA models unable to discriminate between extremely efficient DMUs. Hence, there is a growing interest in improving discrimination power in DEA yet. The aim of this paper is ranking extreme efficient DMUs in DEA based on exp...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
Objective: The aims of this study were to determine energy efficiency and CO2 use pattern of grape production in Zanjan province, Iran by a non-parametric method of data envelopment analysis (DEA). Methods: Initial data were collected using a face to face questionnaire from 42 orchards in Abhar city of Zanjan province which is one of the most important centers of grape production in ...
The purpose of this study is to utilize a new method for ranking extreme efficient decision making units (DMUs) based upon the omission of these efficient DMUs from reference set of inefficient and non-extreme efficient DMUs in data envelopment analysis (DEA) models with constant and variable returns to scale. In this method, an L2- norm is used and it is believed that it doesn't have any e...
the present study was an attempt to determine the types of motivation and levels of foreign language learning anxiety among efl students studying at azad and state universities in kermanshah and to determine the relationship between these two factors and language proficiency and gender. to this end, the foreign language learning motivation scale, by deci and ryan )1985(, were administered to 12...
efficiency is defined as a concept that determines the input output ratios in an economic system. data envelopment analysis method is a useful tool to estimate the efficiency of a unit. the purpose of this study was to estimate technical efficiency and to determine return to scale of holstein cattle farms in guilan province. therefore, the information including the number of labor and dairy cow...
The Dilemma of Factor Allocation and Wage Difference under the Constant Region-Wide Returns to Scale
In the model setting of multiregional macroeconomic research, constant return on scale all production functions and free flow factors cannot be combined. Otherwise, potential theoretical conflict, that is, problem contradiction equations, may arise. If there is a unified capital interest rate in market regions remains unchanged, it necessary to set restrictions labor force order realize differe...
Optimal firm size and patterns of returns to scale among the local exchange companies in the U.S. telecommunications industry are estimated for the years: 1975, 1978, 1981, 1984, 1987 and 1990. The independent companies display increasing returns to scale, while the Baby Bells display constant or decreasing returns to scale. The independent companies operate at a scale smaller than optimal size...
Evaluate the performance of companies on the Stock Exchange using non-parametric methods is very important. DEA and DEA-R with the strategies for piecewise linear frontier production function and use of available data, assess the stock company. In this study, using a neural network algorithm DEA and DEA-R is suggested to classify the first companies in the stock exchange; Secondly, using the...
educational researchers have provided evidence that teachers’ emotional intelligence has strong effects on various aspects of teaching and learning. yet, in the field of teaching english to speakers of other languages (tesol), inquiry into teachers’ emotional intelligence is nearly limited. given its documented powerful impact on teaching practices and student learning, it is critical to pursue...
