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.

283 Background: The rising cost of oncology care in the US is an ongoing societal challenge, and identifying biomarkers that inform clinical decisions and reduce the use of ineffective therapies remains elusive. A splice variant of the androgen receptor, AR-V7, was found to confer resistance to Abi and Enza in men with mCRPC, but did not negatively affect responses to taxanes, suggesting that early use of chemotherapy may be a more effective option for AR-V7(+) pts. With the recent development of a CLIA-certified clinical assay for AR-V7 at Johns Hopkins, we hypothesized that AR-V7 testing in mCRPC pts may result in cost savings by avoiding futile treatment with Abi/Enza in men with AR-V7(+) disease. Methods: We calculated the cost savings of performing AR-V7 testing in mCRPC pts prior to starting Abi/Enza (and avoiding these drugs in AR-V7(+) men) versus treating all mCRPC pts with Abi/Enza (without use of the biomarker). We have set the cost of the AR-V7 assay at $1000. The cost of 3 months of Abi/Enza (the minimum time it would take to determine resistance, clinically) was approximated at $20,000. We estimated that 30,000 mCRPC pts per year are eligible for Abi/Enza in the US. Results: In our prior studies, about 30% of mCRPC pts previously treated with Abi/Enza had detectable AR-V7 in CTCs. Assuming an AR-V7 prevalence of 30%, about 9,000 AR-V7(+) mCRPC pts per year would receive ineffective treatment with Abi/Enza, at an estimated cost of $180 Million. The upfront cost of testing all mCRPC pts who are Abi/Enza-eligible for AR-V7 is $30 Million, resulting in a net cost savings of $150 Million. When performing a continuous cost-benefit analysis after assuming other prevalences of AR-V7 (ranging from 4% to 50%) and a range of costs for Abi/Enza ($2000 to $24,000 per 3 months), we determined that AR-V7 testing would result in a cost savings as long as the prevalence of AR-V7 is > 5% (if the cost of 3 months of Abi/Enza remains at $20,000). Conclusions: AR-V7 testing in mCRPC pts (at $1000/test) is cost-beneficial when considering the current price of Abi/Enza, and may reduce the ineffective use of Abi/Enza leading to a net cost savings to the healthcare system.

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.

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.

This article analyzes definitions and the role of hostile takeovers at the Russian and European markets for corporate control. It develops the methodology of assessing the efficiency of anti-takeover defenses adapted to the conditions of the Russian market. The paper uses the cost-benefit analysis, where the costs and benefits of the pre-bid and post-bid defenses are compared.

Many countries are investing in measures to improve surface water quality, but the investment programmes for so doing are increasingly becoming subject to cost-benefit analysis. Whilst the cost of control measures can usually be determined for individual improvement schemes, there are currently no established procedures for valuing the benefits attributable to improved surface water quality. The paper describes a methodology that has been derived that now makes this possible.

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

In 1985, Boehlert (Fish. Bull. 83: 103–117) suggested that fish age could be estimated from otolith measurements. Since that time, a number of inferential techniques have been proposed and tested in a range of species. A review of these techniques shows that all are subject to at least one of four types of bias. In addition, they all focus on assigning ages to individual fish, whereas the estimation of population parameters (particularly proportions at age) is usually the goal. We propose a new flexible method of inference based on mixture analysis, which avoids these biases and makes better use of the data. We argue that the most appropriate technique for evaluating the performance of these methods is a cost–benefit analysis that compares the cost of the estimated ages with that of the traditional annulus count method. A simulation experiment is used to illustrate both the new method and the cost–benefit analysis.
