Welfare economics typically holds that market outcomes are Pareto efficient only if markets are competitive and average costs are constant or increasing. Otherwise, to attain market efficiency requires some regulatory implementation of a rule to equate price to marginal cost, though the ability of such a pricing rule to accomplish this is tempered by second-best considerations. In contrast to t...

We discuss the design of multi-dimensional tender and auction mechanisms that combine Data Envelopment Analysis (DEA) and auction theory. The mechanisms select an agent to perform or acquire a project characterized by multiple attributes. The optimal configuration of the multiple attributes is settled endogenously by trading off the costs to the provider with the benefits to the acquiring. This...

The carbon emission of China’s industry accounts for more than 70% of the total in the nation, thus the implementation of carbon emission quota trading in industry is of great importance to realize China’s national carbon emission reduction targets. Meanwhile, the allocation of carbon emission quota among sectors or enterprises proves the first and critical step. For this reason, this paper con...

Configuration was one of the first tasks successfully approached via AI techniques. However, solving configuration problems can be computationally expensive. In this work, we show that the decomposition of a configuration problem into a set of simpler and independent subproblems can decrease the computational cost of solving it. In particular, we describe a novel decomposition technique exploit...

recently, many countries have paid substantial attention to power generation from biomass gasification, particularly through small-scale plants. a number of power plant models have been suggested and analyzed; however, certainly, desirable configurations have not been identified yet. moreover, their performances are ordinarily difficult to compare, especially owing to the fact that working hypo...

the present study is an attempt toward evaluating the performance of portfolios and asset selectionusing cross-efficiency evaluation. cross-efficiency evaluation is an effective way of ranking decisionmaking units (dmus) in data envelopment analysis (dea). conventional dea models assume nonnegativevalues for inputs and outputs. however, we know that unlike return and skewness, varianceis the on...

one of the effective methods for improving the efficiency of an organization is benchmarking against successful organizations. not only benchmarking could be a technique for identifying problems but also it greatly helps managers in relations of the design of processes. among strategic and infrastructure industries in each country, the electricity industry is one of the most important and criti...

shoot:root ratio, dry matter partitioning, growth analysis, and water use efficiency of oat (avena sativa l., cv. walker) was investigated under excessive nitrogen (n) as 200 mg n kg-1 (n1p0), excessive phosphorus as 200 mg p kg-1 (n0p1), and combined 100 mg n+100 mg p kg-1 (n2p2), and the control (n0p0) as check in a pot experiment at dryland agriculture institute, west texas a and m universit...

evaluation of corporate performance has been one of the main issues in managing decision making. nowadays, evaluation of the suppliers is a completely strategic process because organizations rarely change their suppliers. thesuppliers also do their best to remain stable in the loop of supply chain. hence, it is important to evaluate the suppliers and not something to be done once at a time. it ...
