Student Ethical Perceptions and Ethical Action Propensities: An Analysis of Situation Familiarity

Recently McCuddy and Peery (1996) have suggested that business students may not respond the same way to unfamiliar business ethical dilemmas as they would to more familiar academic ethical dilemmas. The purpose of this study was to present the same students with both unfamiliar business dilemmas as well as possibly more familiar academic dilemmas in order to examine this issue.Findings of the study revealed that students did not exhibit different perceptions of the unethical actions performed in the academic and accounting/business ethical vignettes. However, the students indicated that both they and their peers would be more likely to act unethically to resolve the dilemmas in the accounting/business cases than in the academic cases. This finding is troubling in that it suggests that students either feel less compelled to act ethically in business, or that they perceive that ethical standards in the business world are generally low when compared to their current educational environment. In addition, the students in the study maintained the same halo effect (i.e., the difference between an individual's perception of their likelihood of performing an unethical action compared to their perception of their peers' likelihood to perform the same unethical action) across the two types of ethical dilemma.     

Poverty and biodiversity: Measuring the overlap of human poverty and the biodiversity hotspots

In an effort to prioritize conservation efforts, scientists have developed the concept of biodiversity hotspots. Since most hotspots occur in countries where poverty is widespread, the success of conservation efforts depends upon the recognition that poverty can be a significant constraint on conservation, and at the same time conservation is an important component to the alleviation of long-term poverty. In this paper we present five key socio-economic poverty indicators (access to water, undernourishment, potential population pressure, number living below poverty line and debt service) and integrate them with an ecologically based hotspots analysis in order to illustrate magnitude of the overlap between biological conservation and poverty. The analysis here suggests that the overlap between severe, multifaceted poverty and key areas of global biodiversity is great and needs to be acknowledged. Understanding the magnitude of overlap and interactions among poverty, conservation and macroeconomic processes is crucial for identifying illusive, yet possible, win-win solutions.     

Nowcasting with payments system data

We consider the potential usefulness of a large set of electronic payments data, comprising the values and numbers of both debit card transactions and cheques that clear through the banking system, for the problem of reducing the current-period forecast (‘nowcast’) loss for (the growth rates of) GDP and retail sales. The payments system variables capture a broad range of spending activity and are available on a very timely basis, making them suitable current indicators. We generate nowcasts of GDP and retail sales growth for a given month on seven different dates, over a period of two and a half months preceding the first official releases, which is the period over which nowcasts would be of interest. We find statistically significant evidence that payments system data can reduce the nowcast error for both GDP and retail sales growth. Both debit transaction and cheque clearance data are of value in reducing nowcast losses for GDP growth, although the latter are of little or no value when debit data are also included. For retail sales, cheque data appear to produce no further nowcast loss reductions, regardless of whether or not debit transactions are included in the nowcasting model.     

The volunteer's dilemma and alternate solutions for ensuring responsibility within accountable care organizations

ABSTRACT

The emphasis on accountable care organizations (ACOs) in recent health care reform increases the potential for social dilemmas such as the volunteer's dilemma within networks of providers who collectively share responsibility for a patient population. Providers in an ACO often receive financial incentives based on how well the group performs in defined quality measures. Care interventions may be indicated for certain patients, such as postdischarge follow-up to prevent readmission. However, the providers conducting the interventions may be unreliable if they vary in their belief in the intervention's effectiveness. We characterize such potential for care coordination failures as instability of an asymmetric equilibrium, illustrated by an example in which ACO patients would benefit from interventions to prevent readmission but individual providers or care teams do not perceive sufficient value in conducting the intervention. We then propose three economic mechanisms that can help ensure that patients receive indicated interventions, illustrate the impact of each with an example, and explore conditions that lead to significant improvements in overall utility.     

Decision rules used by male and female business students in making ethical value judgments: Another look

This study was conducted to corroborate findings that females invoke a decision rule that is significantly different from that of their male counterparts when making ethical value judgements. In addition, the study examines whether the same decision rule is used by men and women for all types of ethical situations. The results show that males and females use different decision rules when making ethical evaluations, although there are types of situations where there are no significant differences in decision rules used by men and women. The results do not suggest that any one particular decision rule is used by the majority of either males or females in different types of ethical judgements. There is a greater diversity in decision rules used by females than by males.Sharon Galbraith, Ph.D., is an Assistant Professor in the Albers School of Business and Economics at Seattle University, Seattle, Washington.

Circuit Breakers and the Tail Index of Equity Returns

Using the tail index of returns on U.S. equities as a summarymeasure of extreme behavior, we examine changes in the equitymarkets surrounding the development of program trading for portfolioinsurance, the crash of 1987, and the subsequent introductionof circuit breakers and other changes in market architecture.Recently-developed tests for the null of constancy of the tailindex, versus the alternative of a change at an unknown date,permit inference on changes in extreme behavior over a longtime period while allowing for second-moment dependence in thereturn data. We find strong evidence of a decrease in the tailindex (increase in the probability of extreme events) aroundthe beginning of large-scale program trading, and weaker, butstill substantial, evidence of further significant change inthe tail index following the introduction of circuit breakers.Point estimates of the tail index suggest that the tail indexmay have roughly regained pre-program trading levels. More generally,the results tend to suggest that long samples of U.S. equityreturns should not be treated as samples from a single distributionfunction, particularly in examining extremes.     

Locational determinants of major US air passenger markets by metropolitan area

The paper examines the influence of metropolitan characteristics in determining the locations of major air traffic markets in the US. In general, the likelihood of a major air passenger market locating in any given metropolitan area is primarily determined by the metropolitan area's population size and overall propensity for air travel. The study shows that on average, a major air passenger market has over 3 million people while a minor market has a population base of about 760,000. The propensity of a population to fly is mainly a function of a number of social and economic indicators, the most important of which was found to be employment in professional–scientific–technical services and management activities.     

Pacioli's Example Entries—a Conundrum Resolved?

This paper discusses the nature of the 10 example paragraph entries at the end of Pacioli's bookkeeping treatise. It concludes that these are entries from fledgling banking operations involving one account holder and one borrower who, along with two others, has financial transactions with the account holder. The widely held assumption that they are examples of entries in the Ledger is set aside and it is concluded that, on the basis of the available evidence, they are examples of entries in a Ricordanze, a record book Pacioli described as being used to record items of this type.     

Bringing Ecosystem Services into the Real World: An Operational Framework for Assessing the Economic Consequences of Losing Wild Nature

Policy action to halt the global loss of biodiversity and ecosystems is hindered by the perception that it would be so costly as to compromise economic development, yet this assumption needs testing. Inspired by the recent Stern Review on the Economics of Climate Change, the leaders of the G8+5 nations commissioned a similar assessment of the economics of losing biodiversity, under the Potsdam Initiative on Biodiversity. Here, we propose a conceptual framework for such a global assessment which emphasizes several critical insights from the environmental economics and valuation literature: contrasting counterfactual scenarios which differ solely in whether they include specific conservation policies; identifying non-overlapping benefits; modeling the production, flow, use and value of benefits in a spatially-explicit way; and incorporating the likely costs as well as possible benefits of policy interventions. Tackling these challenges, we argue, will significantly enhance our ability to quantify how the loss of benefits derived from ecosystems and biodiversity compares with the costs incurred in retaining them. We also summarise a review of the current state of knowledge, in order to assess how quickly this framework could be operationalized for some key ecosystem services.
