Points of Reference and Individual Differences As Sources of Bias in Ethical Judgments

The authors demonstrate that ethical judgments can be biased when previous judgments serve as a point of reference against which a current situation is judged. Scenarios describing ethical or unethical sales practices were used in an experiment to prime subjects who subsequently rated the ethics of an ethically ambiguous target scenario. The target tended to be rated as more ethical by subjects primed with unethical scenarios, and less ethical by subjects primed with ethical scenarios. This "contrast effect," however, is contingent upon individual differences. Specifically, subjects with high (versus low) needs for cognition are more likely to process and use the information presented in the priming scenarios as a point of reference against which to judge the target situation, and hence more prone to the contrastive bias. Implications for avoiding unintentional moral relativism in business decision-making are discussed.     

Potential of woody biomass production for motivating widespread natural resource management under climate change

In this study we assessed the potential of woody biomass (short-rotation Mallee Eucalypts) for renewable energy generation as an economically viable way of motivating widespread natural resource management under climate change in the 11.9 million ha Lower Murray agricultural region in southern Australia. The spatial distribution of productivity of agricultural crops and pasture, and biomass was modelled. Average annual economic returns were calculated under historical mean (baseline) climate and three climate change scenarios. Economically viable areas of biomass production were identified where the profitability of biomass is greater than the profitability of agriculture under each scenario for three factory gate biomass prices. The benefits of biomass production for dryland salinisation, wind erosion, and carbon emissions reduction through biomass-based renewable energy production were also modelled. Depending on climate scenario, at the median price assessed ($40/tonne) biomass production can generate $51.4–$88 M in annual net economic returns, address 41,226–165,577 ha at high risk of dryland salinisation and 228,000–1.4 million ha at high risk of wind erosion, and mitigate 10.4–12 million tonnes of carbon (CO₂^−e) emissions annually. Economically viable areas for biomass production expanded under climatic warming and drying especially in more marginal agricultural land. Under the baseline, the area at high risk of dryland salinisation was more than double that at high risk of wind erosion. However, under climatic warming and drying the relative importance of these two natural resource management objectives switched with the area at high risk of wind erosion becoming much larger. As biomass production can achieve multiple natural resource management objectives, it may provide a land use policy option that is adaptable to changing priorities and economically resilient given climatic uncertainties. For such a significant and enduring land use change policy it is prudent to assess both the economic and environmental potential under climate change.     

The dual-earner dad penalty in salary progression

This study investigates four alternative theoretical explanations for the gap in salaries between dual-earner and traditional male managers. The sample was 348 married male managers with children at home. They were employed by twenty Fortune 500 organizations. The data show that when controlling for work force experience and industry differences, salaries of the dual-earner male managers increased an average of 59% over five years, while the salaries of traditional managers increased by 70%. This gap could not be accounted for by differences between the groups in human capital or conformance to social norms related to the family. Implications of the findings are discussed in terms of the validity of signals of hours in the office and wife as resource. © 1996 by John Wiley & Sons, Inc.     

COMBINING REVEALED AND STATED PREFERENCE DATA TO ESTIMATE THE NONMARKET VALUE OF ECOLOGICAL SERVICES: AN ASSESSMENT OF THE STATE OF THE SCIENCE

Abstract This paper reviews the marketing, transportation and environmental economics literature on the joint estimation of revealed preference (RP) and stated preference (SP) data. The RP and SP approaches are first described with a focus on the strengths and weaknesses of each. Recognizing these strengths and weaknesses, the potential gains from combining data are described. A classification system for combined data that emphasizes the type of data combination and the econometric models used is proposed. A methodological review of the literature is pursued based on this classification system. Examples from the environmental economics literature are highlighted. A discussion of the advantages and disadvantages of each type of jointly estimated model is then presented. Suggestions for future research, in particular opportunities for application of these models to environmental quality valuation, are presented.     

A decision‐analytic approach to screening in chemical alternatives assessment

Material selection in the chemistry value chain involves consideration of many objectives, including cost, performance, health risk, and environmental impact. Alternatives assessment is an emerging tool for guiding complex decisions with respect to these goals. As a relatively new method, the process is not yet well developed, especially with respect to how trade‐offs among objectives can be assessed accurately and inexpensively. Using paint strippers alternatives assessment as an illustrative example, we show how an established decision‐analytic method, known as comparative screening, allows for a multistep process with gradually increasing information needs. Compared with existing methodological approaches, comparative screening instills flexible and consistent treatment of trade‐offs. This is important because it maximizes the potential for a robust assessment while minimizing arduous data collection. Further, its use in the alternatives assessment process can support the selection of more sustainable materials.     

A Closed-Form,After-Tax,Net Present Value Solution to the Mortgage Refinancing Decision

Refinancing one's mortgage is often an attractive, wealth-enhancing option for homeowners in a declining mortgage rate environment. In some respects the decision is simple to analyze because future cash flows are relatively easy to define for fixed-rate mortgages. In other respects, however, the decision is nuanced by option pricing and tax considerations. The analysis must first begin with accurate after-tax, net present value solutions for varying potential holding periods. This study improves upon previous studies, which either ignore tax implications or address them iteratively in spreadsheet model solutions, by introducing a closed-form model that incorporates the ever-changing tax shield of the interest portion of each mortgage payment. Further, unlike many previous studies, our model does not assume that the current and replacement mortgages have equal remaining terms.     

Economics at the FTC: Hospital Mergers,Authorized Generic Drugs,and Consumer Credit Markets

Economists at the Federal Trade Commission pursue the agency’s competition and consumer protection missions. In this year’s essay, in antitrust, we discuss various aspects of our hospital merger analyses as well as the effects of authorized generic drugs on consumers and competition. In consumer protection, we describe two ongoing studies on the use of credit-based insurance scores to price homeowners insurance, and the accuracy of consumers’ credit reports that are provided by credit bureaus.     

Tainted portfolios: How impairment accounting rules restrict security sales

Contrary to claims that fair value accounting exacerbated banks’ securities sales during the recent financial crisis, we present evidence that suggests – if anything – that the current impairment accounting rules served as a deterrent to selling. Specifically, because banks must provide evidence of their ‘intent and ability’ to hold securities with unrealized losses, there are strong incentives to reduce, rather than increase, security sales when market values decline to avoid ‘tainting’ their remaining securities portfolio. Validating this concern, we find that banks incur greater other‐than‐temporary impairment (OTTI) charges when they sell more securities. We then find that banks sell fewer securities when their security portfolios have larger unrealized losses (and thus larger potential impairment charges), and these results are concentrated in banks with homogenous securities portfolios, expert auditors, more experienced managers, and greater regulatory capital slack. Overall, our results suggest that – contrary to critics’ claims – the accounting rules appear to have reduced banks’ propensity to sell their securities during the financial crisis.
