Producers' and consumers' risk perceptions and preferences can affect perceived costs and benefits of agricultural water quality protection. Many studies find that integrated pest management actually reduces economic risks to farmers. Results from crop rotation and conservation tillage studies are mixed, while nutrient management studies indicate a potential for higher risk compared with conventional practices. Uncertainty about pollution damages to water resources is likely also to increase the perceived benefits of a given quantity of water quality protection practices. Public policies to reduce uncertainty about the costs and benefits of water quality protection practices may produce net social benefits.  相似文献

The current audit environment encourages auditors to conduct defensive auditing procedures in lieu of using new, innovative, and potentially more effective audit procedures, due to concerns these procedures may be second-guessed in litigation or by audit inspectors such as the PCAOB. As a result, auditors may prefer traditional “generally accepted” procedures over innovative procedures that are potentially more effective. We test recent proposals that an Audit Judgment Rule (AJR) encourages the use of innovative, and potentially more effective, audit procedures analogous to the similar Business Judgment Rule that affords legal protections to corporate directors. Under an AJR, litigators or audit inspectors could not second-guess auditor judgments, even if they perceive that alternate judgments would have ordinarily been reached, provided the auditor's judgment was made in good faith and in a rigorous manner. However, the AJR's requirements that auditors must defend the rigor of their innovative judgments could potentially backfire and lead auditors to select more traditional procedures. Under the framework of goal activation theory, we conduct an experiment with audit managers and seniors and find that an AJR makes auditors less likely to select innovative audit procedures, particularly when audit risk is high. They do so despite believing the innovative procedures to be more effective than the traditional procedures. Findings from a supplementary experiment with experienced auditors further suggest that national office affirmation of the reasonableness of the procedures does not help overcome this effect. Overall, our findings suggest that an AJR may have the unintended consequence of further increasing auditors' focus on more traditional, and potentially less effective, audit procedures.  相似文献

This paper examines the role which organizational context factors play in individual ethical decision making. Two general propositions are set forth, examining the linkage between ethical work climate and decision making. An agenda for research and the potential implications of the study and practice of managerial ethics are then discussed.  相似文献

Although many challenges remain, business ethics is flourishing in North America. Prominent organizations give annual business ethics awards, investments in socially screened mutual funds are increasing, ethics officers and corporate ombudspersons are more common and more influential, and new ideas are being tested in practice. On the academic side, two major journals specializing in business ethics are well-established and other major journals often include articles on business ethics and new organizations emphasizing ethics have been initiated. Within business schools, the number of endowed chairs is growing and the ethics curriculum is expanding. Canada is a major player in the business ethics discipline while business ethics in Mexico is just beginning to emerge as a focus of interest in both the business and academic communities.  相似文献

In recent years, corporate sponsorship has become anincreasingly important element of the marketing communicationsmix. This paper uses data from the 1996 Atlanta Summer OlympicGames to measure the value of Olympic sponsorship. Using stockreturn data, we find that the shareholders of sponsoring firmsearn negative average abnormal returns around announcement ofOlympic sponsorship agreements. This finding, consistent withan agency cost explanation of corporate investment practices,is robust to variation in a number of firm- and sponsorship-specificvariables. In addition, cross-sectional analysis supports themonitoring hypothesis, as significant equity ownership by institutionalinvestors is positively related to abnormal returns around announcement.Our results suggest that utilizing Olympic sponsorships in themarketing communications mix may not be value-enhancing.  相似文献

Modeling Methods for Discrete Choice Analysis   总被引:2,自引:3,他引:2  
This paper introduces new forms, sampling and estimation approaches fordiscrete choice models. The new models include behavioral specifications oflatent class choice models, multinomial probit, hybrid logit, andnon-parametric methods. Recent contributions also include new specializedchoice based sample designs that permit greater efficiency in datacollection. Finally, the paper describes recent developments in the use ofsimulation methods for model estimation. These developments are designed toallow the applications of discrete choice models to a wider variety ofdiscrete choice problems.  相似文献

Despite the recent emergence of many new ethical decision making models, there has been minimal emphasis placed on the impact of escalating commitment on the ethical decision making process. In this paper a new variable is introduced into the ethical decision making literature. This variable, exposure to escalation situations, is posited to increase the likelihood that individuals will choose unethical decision alternatives. Further, it is proposed that escalation situations should be included as a variable in Jones's (1991) comprehensive model of ethical decision making. Finally, research propositions are provided based on the relationship between escalating commitment and the ethical decision making process.  相似文献

"The proper use of demographic information can add significantly to the ability to analyze and forecast economic activity. With housing, short-run forecasting is difficult and long-term forecasting impossible without considering changing demographic factors. Combining detailed demographic analysis with sound structural econometric modeling of the cyclical factors underlying the demand for and the supply of housing has resulted in significantly more accurate analyses and forecasts of the [U.S.] housing market."  相似文献

Despite many valuable contributions, prior research has not completely explained retail pricing behavior. This study employs scanner data for 36 fresh produce items analyzing the relationship between costs of goods sold and retail prices to provide further insight into retail pricing behavior. Implications include: (1) where ‘natural’ variation in produce prices do not already exist from the supplier, retailers appear to introduce the variation themselves, independent from shipping point price; and (2) to the extent that supplier-retailer contracts for fresh produce develop, the resulting stabilizing influence on costs may have the preserve effect of increasing retail price variability to consumers.  相似文献
