AbstractGlobal deterioration of marine ecosystems, together with increasing pressure to use them, has created a demand for new, more efficient and cost-efficient monitoring tools that enable assessing changes in the status of marine ecosystems. However, demonstrating the cost-efficiency of a monitoring method is not straightforward as there are no generally applicable guidelines. Our study provides a systematic literature mapping of methods and criteria that have been proposed or used since the year 2000 to evaluate the cost-efficiency of marine monitoring methods. We aimed to investigate these methods but discovered that examples of actual cost-efficiency assessments in literature were rare, contradicting the prevalent use of the term “cost-efficiency.” We identified five different ways to compare the cost-efficiency of a marine monitoring method: (1) the cost–benefit ratio, (2) comparative studies based on an experiment, (3) comparative studies based on a literature review, (4) comparisons with other methods based on literature, and (5) subjective comparisons with other methods based on experience or intuition. Because of the observed high frequency of insufficient cost–benefit assessments, we strongly advise that more attention is paid to the coverage of both cost and efficiency parameters when evaluating the actual cost-efficiency of novel methods. Our results emphasize the need to improve the reliability and comparability of cost-efficiency assessments. We provide guidelines for future initiatives to develop a cost-efficiency assessment framework and suggestions for more unified cost-efficiency criteria.

One of the first lessons that students of cost-benefit analysis (CBA) learn is to ask whether projects or policies which they are studying generate additional benefits or costs, relative to the status quo. They are also told to be very careful in defining the project/policy which is the subject of their analysis. In my view, the ecological concept of resilience fails the CBA test, when applied to the study of economic and social systems, because it offers no additional insights to those we have already, and appears to be poorly defined.

Abstract Contemporary global governance takes place not only through formal inter-governmental organizations and treaties, but increasingly through diverse institutional forms including informal inter-governmental organizations, trans-governmental networks, and transnational public–private partnerships. Although these forms differ in many ways, they are all what we call ‘low-cost institutions’ (LCIs): the costs of creating, operating, changing, and exiting them, and the sovereignty costs they impose, are substantially lower on average than those of treaty-based institutions. LCIs also provide substantive and political governance benefits based on their low costs, including reduced risk, malleability, and flexibility, as well as many of the general cooperation benefits provided by all types of institutions. LCIs are poorly-suited for creating and enforcing binding commitments, but can perform many other governance functions, alone and as complements to treaty-based institutions. We argue that the availability of LCIs changes the cost–benefit logic of institutional choice in a densely institutionalized international system, making the creation of new institutions, which existing research sees as the ‘last resort’, more likely. In addition, LCIs empower executive, bureaucratic, and societal actors, incentivizing those actors to favor creating LCIs rather than treaty-based institutions. The availability of LCIs affects global governance in multiple ways. It reduces the status quo bias of governance, changes its institutional and actor composition, enables (modest) cooperation in times of polarization and gridlock, creates beneficial institutional divisions of labor, and expands governance options. At the same time, the proliferation of LCIs reduces the focality of incumbent institutions, increasing the complexity of governance.

The introduction of Automatic Dependent Surveillance-Broadcast (ADS-B) in Aviation as mandated in the US [3,4] and in Europe [1,2] rests on the (at least theoretical) benefits of the switch of paradigm in ATC surveillance from (continuously) active interrogation of aircraft positions by primary radars to (almost always) automatic broadcast of data by the aircraft. The cost/benefit analysis in favour of this shift weights on the 1) higher frequency and precision of the aircraft information (position, speed, . . . ) made available to ATC/neighbouring aircraft leading to increased safety and increased airspace capacity and 2) on the (at least one) order of magnitude reduction in ground infrastructure costs [5]. Infrastructure needs nontheless to be deployed both on the ground and in the air; and in the end it is the passenger who pays via taxes on tickets or airports services: so what is the status of deployment? This paper investigates, using only open and free data, the status of compliance of aircraft in the European airspace, i.e. how many aircraft flying in Europe comply to the EASA ADS-B mandate.

How do economists persuade their readers that one policy is superior to another? A glance at the literature on welfare economics quickly provides the answer to this question: Economists enter policy debates armed with mathematical models, evaluating options on the basis of their consequences. Economists typically classify a policy change as a welfare (or “potential Pareto”) improvement with respect to the status quo if the gain realized by the winners exceeds the harm sustained by the losers. The best policy becomes the one that generates the highest net benefit.

Data Envelopment Analysis (DEA) is an appropriate tool for estimating various types of efficiency such as cost efficiency. There are two different sates in cost spaces; in the first space prices are equal for all Decision Making Units (DMUs) which is competitive space, and in the second space prices are different form one DMU to another; this is known as non-competitive space. The present paper introduces a new method to assess Cost Efficiency (CE), Revenue Efficiency (RE) and Profit Efficiency (PE) in a non-competitive space. The present paper also proposes a Production Possibility Set (PPS) in which DMUs are evaluated based on both their own prices and the prices of other DMUs in non-competitive space. Moreover, a new decomposition is provided for observed actual cost DMUs based on the cost efficiency model and the proposed PPS, thus the observed actual cost can be shown by summation of several technical, price and allocative efficiency (AE) losses. The biggest advantage of this method comparing to the previous methods is that passive the developed cost efficiency and the cost Production Possibility Set has been developed and the performed decomposition is more accurate; this is because the new inefficiency sources are defined and added to this new decomposition. Therefore, it includes more inefficient sources.

The concept of cost efficiency has become tremendously popular in data envelopment analysis (DEA) as it serves to assess a decision-making unit (DMU) in terms of producing minimum-cost outputs. A large variety of precise and imprecise models have been put forward to measure cost efficiency for the DMUs which have a role in constructing the production possibility set; yet, there’s not an extensive literature on the cost efficiency (CE) measurement for sample DMUs (SDMUs). In an effort to remedy the shortcomings of current models, herein is introduced a generalized cost efficiency model that is capable of operating in a fuzzy environment-involving different types of fuzzy numbers-while preserving the Farrell’s decomposition of cost efficiency. Moreover, to the best of our knowledge, the present paper is the first to measure cost efficiency by using vectors. Ultimately, a useful example is provided to confirm the applicability of the proposed methods.

Peer reviewed scientific publishing is critical for communicating important findings, interpretations and theories in any branch of science. While the value of peer review is rarely doubted, much concern is being raised about the possible biases in the process. I argue here that most of the biases originate in the evolved innate tendency of every player to optimize one’s own cost benefits. Different players in the scientific publishing game have different cost-benefit optima. There are multiple conflicts between individual optima and collective goals. An analysis of the cost-benefit optima of every player in the scientific publishing game shows how and why biases originate. In the current system of publishing, by optimization considerations, the probability of publishing a ‘bad’ manuscript is relatively small but the probability of rejecting a ‘good’ manuscript is very high. By continuing with the current publishing structure, the global distribution of the scientific community would be increasingly clustered. Publication biases by gender, ethnicity, reputation, conformation and conformity will be increasingly common and revolutionary concepts increasingly difficult to publish. Ultimately, I explore the possibility of designing a peer review publishing system in which the conflicts between individual optimization and collective goal can be minimized. In such a system, if everyone behaves with maximum selfishness, biases would be minimized and the progress towards the collective goal would be faster and smoother. Changing towards such a system might prove difficult unless a critical mass of authors take an active role to revolutionize scientific publishing.

The story of Lot is one of many shared by the Qur'an and the Torah, and Lot's offer of his two daughters to his people is presented in a similar way in the two books. This article compares the status of Lot in the Qur'an and Torah, and explores the moral dimensions of his character, and what scholars of the two religions make of this story. The significance of the episodes in which Lot offers his daughters to his people lies in the similarities and differences of the accounts given in the two books and the fact that, in both the past and the present, this story has presented moral problems and criticism has been leveled at Lot. Context is crucial in understanding this story, and exploration of the ways in which Lot and his people are presented is also useful in terms of comparative studies of the two scriptures. This article is divided into three sections: the first explores the depiction of Lot in the two texts, the second explores his moral limitations, and the third discusses the interpretations of various exegetes and scholars of the two books. Although there are similarities between the Qur'anic and Talmudic accounts of this episode, it is read differently by scholars from the two religions because of the different contexts of the respective accounts.
