As widely recognized, human mankind stands before the most challenging problem of preventing anthropogenic climate change. As a response to this, the European Union advocates an ambitious climate policy mix. However, there is no consensus concerning the impact of stringent environmental policy on firms’ competitiveness and profitability. From the traditional ‘static’ point of view there are pro...

data envelopment analysis (dea) is a method for measuring the relative efficiencies of a set of decision-making units (dmus) that use multiple inputs to produce multiple outputs. in this paper, we study the measurement of dmu performances in dea in situations where input and/or output values are given as imprecise data. by imprecise data we mean situations where we only know that the actual val...

data envelopment analysis (dea) measures the relative efficiency of decision making units (dmus) with multiple inputs and multiple outputs. dea-based malmquist productivity index measures the productivity change over time. we propose a dynamic dea model involving network structure in each period within the framework a dea. we have previously published the network dea (ndea) and the dynamic dea ...

production, reproduction, management and economic parameters resulted from recordings of 5 flocks comprised of 720 heads of native goats during annual cycle of reproduction in transhumance, village and farming systems were employed to determine the performance of traits, cost-profit analysis as well as breeding objective. the overall mean for number of salable kid per goat in transhumance, vill...

This paper establishes that the profit-seeking activities of private intermediaries can ensure Pareto efficiency in the standard pure-exchange monetary overlapping generations economy without the need for government monetary or fiscal policy intervention. Moreover, these profit-seeking activities are shown to rule out all aperiodic and kperiodic cycles for k greater than 2. Contrary to much rec...

the present study is an attempt towards remodeling cost, revenue and profit relationship within the network process. the previous models of data envelopment analysis (dea) have been too general in their scope and focused on the input and the output within a black box system, therefore they have not been able to measure various phases simultaneously within a network system. by using these models...

The stock market, take-over bidders, executive pay setters, perhaps Stephen Littlechild himself, even last summer’s weather, all seem to have been undermining RPI–X price-cap regulation. Until recently, price-cap regulation was regarded as demonstrably superior to US-style rate-of-return regulation, and regulatory reform in several countries has embraced price-cap regulation. But in Britain, wh...
