Smart Meter-Angebote: Eine empirische Untersuchung von Kundenpräferenzen

The implementation of smart meters in German households by 2032 is a major step in the transition towards an intelligent and connected energy system. Despite of federal legislation providing a structured plan for the nationwide smart meter rollout including basic product requirements, actors within the energy market have the opportunity to take an active part in shaping the market through appealing product offers and hence to create competitive advantage. This study identifies relevant features of smart meters from literature und business practice, and measures customer’s preferences for these features. Results indicate predominantly positive customer evaluations of smart meter features, amongst which the availability of consumption data, the installation price and rental charges as well as time variable tariffs contribute most to overall utility of smart meters. Finally, findings suggest targeting customers by defining strategies to address privacy concerns, to educate about saving potentials as well as to create differentiated pricing schemes.     

The effect of political visibility on audit effort and audit pricing

This study examines whether auditors adjust their effort and pricing decisions for political visibility. We argue, from the behavioural literature, that political visibility will create the need for more justification by auditors. Using data on actual audit fees, hours and billing rates for a sample of New Zealand public sector companies, we find that total audit fees are positively related to the number of press mentions (our proxy for political visibility). Consistent with our expectations we find that audit fees are monotonically related to audit fees. We also find that auditors increase the hours spent on the audit but not billing rates, which further suggests defensive bolstering by auditors.     

Chief Executive Officer Equity Incentives and Accounting Irregularities

This study examines whether Chief Executive Officer (CEO) equity‐based holdings and compensation provide incentives to manipulate accounting reports. While several prior studies have examined this important question, the empirical evidence is mixed and the existence of a link between CEO equity incentives and accounting irregularities remains an open question. Because inferences from prior studies may be confounded by assumptions inherent in research design choices, we use propensity‐score matching and assess hidden (omitted variable) bias within a broader sample. In contrast to most prior research, we do not find evidence of a positive association between CEO equity incentives and accounting irregularities after matching CEOs on the observable characteristics of their contracting environments. Instead, we find some evidence that accounting irregularities occur less frequently at firms where CEOs have relatively higher levels of equity incentives.     

Accounting infrastructure and accountability in the management of public expenditure in developing countries: A focus on Nigeria

Accountability in the control and management of public funds is one of the most sensitive aspects of the activities of government in all democracies. Hence, the 1999 Constitution of the Federal Republic of Nigeria contains provisions relating to legislative powers and control over public funds. However, the required level of accountability in public expenditure has not been achieved in Nigeria. The situation has remained worrisome even though the country does not lack in the appropriate laws and regulation required to bring sanity into the system. Though there have been some bold steps and initiatives in the recent past by the government by strengthening existing institutions and creating new ones with responsibility for fraud and other controls, the issue of weak accounting infrastructure has not been addressed. The paper argues that accountability in public expenditure can more easily be realized within the context of a sound accounting infrastructure and a robust accounting profession and not in the multiplicity of laws and anti-corruption agencies; all of which are reactive in nature. Therefore, the paper reports on the current state of accounting infrastructure in Nigeria, and conclude with an assessment of the existing agencies and current reform initiatives in ensuring accountability in public expenditure in Nigeria.     

Educational Insights: A Hybrid Course in Risk Management and Insurance

Universities and colleges continue to face constraints related to classroom space and faculty time, thus increasing the need to consider options such as hybrid courses that can leverage available resources. This article discusses the benefits of a hybrid course, as well as its design and implementation at a large, public university. In addition, for universities that use the introduction to risk and insurance course as a significant course for attracting majors, we identify the benefits for students from the use of hybrid courses, such as the variety of materials and activities utilized, as well as the flexibility in scheduling. This information may be useful in marketing the course so that it will be immediately attractive to students.     

Mutual fund herding its impact on stock returns: Evidence from the Taiwan stock market

Using quarterly ownership data which identify identity codes of mutual funds in Taiwan, we investigate mutual fund herding and its impact on stock price. We show that mutual funds tend to follow their own steps in trading rather than follow trades made by other funds. More importantly, evidence of price continuation following mutual fund herd buying suggests that such herding is based on value-relevant information and is consistent with the investigative herding hypothesis. Alternatively, evidence of return reversal following mutual fund herd selling suggests that such herding is non-informational and is consistent with the characteristic herding hypothesis.     

Inter-market competition for NYSE-listed securities under decimals

Blume and Goldstein (J Finance 52:221–244, 1997) suggest that quote competition between trading venues may diminish following tick size reductions. We test this suggestion by studying the competitive landscape in the NYSE-listed stocks before and after decimalization. We find that NBBO (National Best Bid and Offer) participation by non-NYSE venues declines following decimalization consistent with the prediction. At the same time, the importance of quote competitiveness in attracting order flow increases. In addition, although not as active in determining and maintaining the best quotes under decimals, non-NYSE venues become more active in price discovery. Finally, decimalization leads to lower trading costs and to smaller differences in trading costs across trading venues.     

Weekly scheduling models for traveling therapists

This paper presents a series of models that can be used to find weekly schedules for therapists who provide ongoing treatment to patients throughout a geographical region. In all cases, patient-appointment times and visit days are known prior to the beginning of the planning horizon. Variations in the models include single vs. multiple home bases, homogeneous vs. heterogeneous therapists, lunch break requirements, and a nonlinear cost structure for mileage reimbursement and overtime. The single home base and homogeneous therapist cases proved to be easy to solve and so were not thoroughly investigated. This left two cases of interest: the first included only lunch breaks while the second added nonlinear overtime and mileage reimbursement costs. For the first case, 40 data sets were solved, each consisting of either 15 or 20 therapists and between roughly 300 and 540 patient visits over five days. For each instance, we were able to obtain the minimum cost of providing residential healthcare services using a commercial solver. The results showed that CPU time increases more rapidly than total cost as the total number of visits grows. For the second case, which was much more difficult, it was necessary to develop heuristics to find good solutions quickly. Results for 5- through 20-therapist instances are presented and compared to the linear programming relaxation lower bounds. In the first of two parametric analyses, the tradeoff between the number of therapists on staff and the cost of providing service was examined. In the second, a similar tradeoff was explored between cost can the number of home bases used by the therapists.     

Working sick and out of sorts: a cross-cultural approach on presenteeism climate,organizational justice and work–family conflict*

Abstract

A climate of presenteeism has important effects on employee well-being and the organization itself. Our study, based on surveys of health sector employees in six different countries (Brazil, Ecuador, Lebanon, Portugal, Russia and Spain) examines whether organizational justice plays a mediating role in the relationship between a presenteeism climate in the organization and work–family conflict (WFC). Our results indicate that the perception of organizational justice and the presenteeism climate do influence WFC. Moreover, higher levels of WFC were found in non-Latin countries. This study contributes to the work attendance and life balance field by providing cross-cultural empirical evidence corroborating the effect of justice and presenteeism climate on the WFC.     

Rules,rogues, and risk assessors: Academic responses to Enron and other accounting scandals

Abstract

The recent accounting scandals in the USA and the resulting regulation of the US profession via the Sarbanes–Oxley Act have led to the resurrection of an old debate: principles vs. rules. We argue that such a debate is jejune and serves as little more than a diversion from discussing more substantive issues raised by events like Enron and Andersen. Accounting is not confronted by a choice of principles to the exclusion of rules or vice versa. Principles underlie any set of rules, and any implementation of principles will inevitably involve adopting some rules. We take issue with various analyses of the accounting scandals that rely too exclusively on the principles of neo-classical economics. We conclude by identifying four major obstacles impeding meaningful academic and educational treatment of the maladies of which Enron is merely a symptom.
