Abstract The study examined the profitability and technical efficiency of pig production in Ekiti State, Nigeria. A multi-stage sampling technique was employed in the selection of 80 pig farmers. Primary data were collected through structured questionnaire from the selected pig farmers. The data obtained from the farmers were analysed using descriptive statistics, cost benefit analysis and stochastic frontier production function. Findings revealed that majority (82.5 %) of the respondents were male, 40 % were within the active age of 35–46 years that can effectively withstand the rigors and stress involved in pig production, 76.25 % were married with a mean household size of 6people. The cost and return analysis showed that, in one production year, the gross margin was ₦694,592($3,484.44), while the rate of return on investment was ₦0.34 and the Cost Benefit Ratio (CBR) was 1.34 indicating that the enterprise is profitable since BCR is greater than 1. The result of stochastic frontier production function revealed that herd size (P < 0.05), quantity of feed (P < 0.01), capital (P < 0.01) and labour (P < 0.05) increase technical efficiency of the respondents, while inefficiency in the study area was reduced by age of the respondents (P < 0.1), educational level (P < 0.01), household size (P < 0.05), farming experience (P < 0.01) and breed of pig (P < 0.1) reared by the respondents. The mean technical efficiency was 0.86. Although the pig farmers exhibit high technical efficiency in the study area, efficiency could still be increased by 14 % through better use of available resources given current state of technology which could be achieved through farmers’ specific factors like age, education and farming experience.

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.

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.

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.

SUMMARY We conduct a post-implementation research analysis of AS4, a standard guiding voluntary audits of material weakness (MW) remediation disclosures, to understand the reasons for the scarcity of AS4 audits in practice. We use multiple methods (experiments, comment letter analysis, and surveys) to understand the perspectives of key stakeholders. We find that regulators' expectations of the use of the standard did not come to fruition because an equilibrium market for active use of the standard could not be achieved; that managers desire to engage in AS4 audits for the riskier MWs but do not expect the associated costs to be high; and that auditors are reluctant to audit riskier MWs and would charge a considerable risk premium. Finally, we find that investors value AS4 audits, especially for riskier MWs, and find value in an AS4 audit for those risky MWs beyond that of the year-end audit. The overall findings of our study indicate that a mismatch in the cost-benefit functions of the key stakeholders led to a lack of AS4 audits. Our findings are important given the high costs associated with auditing standards development and approval.

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.

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.
