to measure an unbiased farm-specific efficiency of individual dairy farmers, a shadow-price profit frontier adjusted for market distortion was applied to a sample of 860 iranian small intensive dairy farms surveyed in 2005-2006. this measure was then compared with that of unadjusted measure that assumes undistorted market. a multiple general linear model (glm) technique was applied to the data ...

We consider the classical joint pricing and inventory control problem with lost-sales and censored demand in which the customer’s response to selling price and the demand distribution are not known a priori, and the only available information for decision-making is the past sales data. Conventional approaches, such as stochastic approximation, online convex optimization, and continuum-armed ban...

This article deals with an economic order quantity (EOQ) inventory model for items with imperfect quality in fuzzy stochastic environment, wherein shortages are allowed and completely backlogged. Fuzzy stochastic environment means linguistic ‘impreciseness’ and statistical ‘uncertainty’ both appear simultaneously. Due to uncertain demand trend, imperfect production process, natural disaster etc...

During the operation, a tremendous amount of heat is generated in the coal based sponge iron plant and a significant part of this heat associated with the waste gas, remains unutilized. While utilizing this heat in the process the energy demand of the process may be reduced, which decreases the coal consumption, which is the only source of energy for this plant. To utilize the heat associated w...

This paper analyzes the effects of mergers around the world over the past 15 years. We utilize a large panel of data on mergers to test several hypotheses about mergers. The effects of the mergers are examined by comparing the performance of the merging firms with control groups of nonmerging firms. The comparisons are made on profitability and sales. The results show that mergers on average do...

AIM To perform SWOT (strengths, weaknesses, opportunities, and threats) analysis of a clinical laboratory as an economic model that may be used to improve business performance of laboratories by removing weaknesses, minimizing threats, and using external opportunities and internal strengths. METHODS Impact of possible threats to and weaknesses of the Clinical Laboratory at Našice General Coun...

Background The engagement of private practitioners in the public-private mix of tuberculosis (TB) management started in 2007 in Lagos State Nigeria. This study compared the treatment outcomes of patients managed at private for profit (PFP) and private not for profit (PNFP) directly observed treatment short course (DOTS) facilities. Methods A retrospective review of treatment cards of TB patie...

Recent empirical research in banking has found substantial but unexplained differences among bank’s costs and profits, indicating that the industry is not in long-run equilibrium. In this paper, three factors are hypothesized as the source of this out-of-equilibrium behavior: (i) variations in banks’ abilities to match capacity and demand; (ii) variations in risk management; and (iii) variation...

In 2013, around 121 billion US-Dollar have been spend worldwide to promote the investment into renewable energy sources. The most prominent support scheme employed is a feed-in tariff, which guarantees a fixed price for electricity produced by renewable energies sources, usually for around 15 years after the installation of the plant. We study the incidence of wind turbine subsidies due to a fe...

In this paper, we provide further insight into the stock return momentum phenomena by investigating the sources of momentum profits. Applying statistical factor analysis, we identify the most important variables significantly affecting momentum profits: volatility and changes in the currency component of M1. We also document the periodic dynamics of momentum returns that is their inflation at q...
