cotton as a strategic product plays an important role inthe economy of boshrouyehwhere is known as the major cotton producing center of khorasan-e-jonoubi. in this paper, efficiency of boshroyeh cotton farms in 2007 have been calculated using data envelopment analysis (dea) and determinants of efficiency were identified using tobit regression analysis. the data was collected from questionnaires...

This study demonstrates the ecacy of neural implementations of multistage and tree-search quantization. For xed branching ratio we have seen that the tree-search quantizer consistently outperforms the multi-stage structure, though at considerable resource cost. For networks with equal neural resource, the multistage architecture returns signicantly lower mse than the at and tree-search architec...

The potential capabilities and limitations of single ball lenses for coupling laser diode radiation to single-mode optical bers have been analyzed; parameters important to optical ber communications were specically considered. These parameters included coupling eciency, eective numerical apertures , lens radius, lens refractive index, wavelength, magnication in imaging the laser diode on the be...

A new approach for cost-sensitive classification is proposed. We extend the framework of cost-sensitive learning to mitigate risks of huge costs occurring with low probabilities, and propose an algorithm that achieves this goal. Instead of minimizing the expected cost commonly used in cost-sensitive learning, our algorithm minimizes expected shortfall, a.k.a. conditional value-at-risk, known as...

A multi-product cost function is estimated using data on the UK higher education system. The results are used to provide information about average incremental costs, economies of scale and economies of scope in a wide variety of institutions. Implications of the analysis are discussed for the identification of allocative and technical efficiencies in universities. JEL Classification: I2, L1.

A leading explanation in the economic literature is that monetary policy has real effects on the economy because firms incur a cost when changing prices. Using a unique database of cost and retail price changes, we find that variation in menu costs results in up to 13.3% fewer price increases. We confirm that these effects are allocative and have a persistent impact on both prices and unit sale...


 This study was designed to calculate production efficiency (technical, economic and allocative) determinants of inefficiency in open field tomato Punjab, Pakistan. Simple random sampling used for primary data collection from 70 farmers 2014. Data envelopment analysis explored the mean technical (79.4%), allocative (58.1%) (45.9%) efficiency. It showed capability 21.6 41.9% reduction inpu...

The growing use of cost-effectiveness analysis (CEA) to evaluate specific interventions is dominated by studies of prospective new interventions compared with current practice. This type of analysis does not explicitly take a sectoral perspective in which the costs and effectiveness of all possible interventions are compared, in order to select the mix that maximizes health for a given set of r...

Abstract Technical, allocative, and economic input efficiency scores were estimated for an unbalanced panel of Swedish dairy farms, using data envelopment analysis (DEA) and the stocha...

Laboratory experiments employing an induced-values methodology often report on allocative efficiencies observed. That methodology requires experimenters know subjects’ motivations precisely, questionable in labs, impossible in field experiments. Allocative efficiency implies a hypothetical costless aftermarket would be inactive. An allocation mechanism’s outcome is defined to be behaviorally ef...
