RePEc:aso:wpaper Follow on MyIDEAS - Hailong Cai & Tianyao Yan (2018): Technology efficiency or allocation efficiency
Design/methodology/approach - Based on the panel data concerning farms from 31 provinces in China in 2009–2014, technology efficiency and allocation efficiency in cereal production were measured based on the Translog production function. ... Further, the presence of this IR is due to allocation efficiency rather than technology efficiency. Results of technology efficiency show that there is no significant difference between different size groups; in other words, even the larger size groups enjoy a higher technology efficiency in rice production. ... Practical implications - The scale consolidation of cropland is harmless to the efficiency of factor utilization and, conversely, may contribute in improving the technology efficiency of specific crops (like rice). ... This paper steps forward from the perspective of technology efficiency and allocation efficiency and explores the exact resources of IR with up-to-date and representative data and hopes to find some new conclusions.
RePEc:eme:caerpp:caer-04-2018-0074 Save to MyIDEAS - Shaista Arshad (2017): Examining the Efficiency
As the primary role of the capital market is to allocate the economy’s resources, the fundamental need for an efficient market arises from the importance of efficient resource allocations, which in turn will help the economy. In light of the efficient market hypothesis (EMH), several studies have been undertaken over the past two decade, but very few have been on the Organization of Islamic Cooperation (OIC). This chapter focuses on analysing the weak-form efficiency of OIC member stock markets to determine their efficiency rankings during different business cycles. The results are indicative of improving efficiency over the past decade.

In this work we make the research concerning the subject of defining the essence of the concepts “efficiency” and “efficiency of investment project.” We present and summarize the achieved result on the problem of evaluating the efficiency of investment projects before the carrying special survey. ... Based on the analysis, we reveal the essence of the concept “efficiency,” being defined in the articles. As a result, the signs and definition of the “efficiency” concept are refined. ... It is established that the criterion “energy efficiency,” as a special case of an economic criterion, is more relevant and used in the evaluation of investment projects.
RePEc:spr:prbchp:978-3-319-70055-7_13 Save to MyIDEAS - K S Park (2007): Efficiency bounds and efficiency classifications in DEA with imprecise data
Imprecise data envelopment analysis (IDEA) has been developed to measure the relative efficiency of decision-making units (DMUs) whose input and/or output data are imprecise. In this paper, we show two distinct strategies to arrive at an upper and lower bound of efficiency that the evaluated DMU can have within the given imprecise data. The optimistic strategy pursues the best score among various possible scores of efficiency and the conservative strategy seeks the worst score. ... We target how to deal with imprecise data in a more general form and, under this circumstance, we make it possible to grasp an upper and lower bound of efficiency. The generalized method we develop in this paper also gives rise to a new scheme of efficiency classifications that is more detailed and informative than the standard efficient and inefficient partition.

We examine how an exogenous improvement in market efficiency, which allows the stock market to obtain more precise information about the firm's intrinsic value, affects the shareholder–manager contracting problem, managerial incentives, and shareholder value. ... We show that an increase in market efficiency weakens managerial incentives by making the firm's stock price less sensitive to the firm's current performance. The impact on real efficiency and shareholder value varies depending on the composition of the firm's intrinsic value.
RePEc:eee:corfin:v:29:y:2014:i:c:p:561-578 Save to MyIDEAS - Tarmo Räty (2002): Efficient Facet Based Efficiency Index: A Variable Returns to Scale Specification
This paper discusses variable returns to scale and suggests the use of efficient facets (EFs) in the reference technology. It is found to give a lower bound of the efficiency scores. Most importantly, efficiency measured with respect to EFs—the EF based efficiency index—may decrease if additional variables are introduced but are disposed in production. Thus, units are penalized for disposal of incoming variables, and the EF based efficiency index captures the net efficiency of a unit. EF is found to be a useful tool also to search a suitable set of variables for efficiency measurement.

This paper investigates a rather neglected issue regarding the impact of Energy Efficiency Technologies (EETs) on firms' productive performance. ... The empirical findings reveal that the EETs affect positively the firms' technical efficiency and negatively the deterministic part of the frontier.
RePEc:eee:ecmode:v:27:y:2010:i:1:p:274-283 Save to MyIDEAS - Rothbard, Murray (2009): Myth of efficiency
One of the main arguments of Rizzo is that the notion of efficiency has no meaning outside the context of pursuit of specific objectives. But he makes too many concessions, arguing that "of course, it [common law] is efficient" in relation to the achievement of certain goals. In fact, on several levels there are serious differences regarding the very concept of efficiency in the application of social institutions or facilities.
