Bt cotton remains one of the most widely grown biotech crops among smallholder farmers in lower income countries, and numerous studies attest to its advantages. However, the effectiveness of Bt toxin, which depends on many technical constraints, is heterogeneous. In Pakistan, the diffusion of Bt cotton occurred despite a weak regulatory system and without seed quality control; whether or not many varieties sold as Bt are in fact Bt is also questionable. We utilise nationally representative sample data to test the effects of Bt cotton use on productivity. Unlike previous studies, we invoke several indicators of Bt identity: variety name, official approval status, farmer belief, laboratory tests of Bt presence in plant tissue, and biophysical assays measuring Bt effectiveness. Only farmer belief affects cotton productivity in the standard production model, which does not treat Bt appropriately as damage‐abating. In the damage control framework, all Bt indicators reduce damage from pests. Biophysical indicators have the largest effect and official approval has the weakest. Findings have implications for impact measurement. For policy‐makers, they suggest the need, on ethical and productivity grounds, to improve variety information and monitor variety integrity closer to point of sale.  相似文献

This paper investigates whether maintaining a reputation for consistently beating analysts' earnings expectations can motivate executives to move from “within GAAP” earnings management to “outside of GAAP” earnings manipulation. We analyze firms subject to SEC enforcement actions and find that these firms consistently beat analysts' quarterly earnings forecasts in the three years prior to the manipulation period and continue to do so by smaller “beats” during the manipulation period. We find that manipulating firms beat expectations around 86 percent of the time in the 12 quarters prior to the manipulation period (versus 75 percent for control firms) and that manipulation often ends with a miss in expectations. We document that executives of manipulating firms face strong stock market and CEO pressure to perform. Prior to the manipulation period, these firms have high analyst optimism, growing institutional interest, and high market valuations, along with powerful CEOs. Further, we find that maintaining a reputation for beating expectations is more important than CEO overconfidence and is incremental to CEO equity incentives for explaining manipulation. Our results suggest that pressure to maintain a reputation for beating analysts' expectations can encourage aggressive accounting and, ultimately, earnings manipulation.  相似文献

In the last five years, a number of U.S. companies have either moved their locus of incorporation to countries with more favorable tax laws, or announced such moves. Given this trend toward “inversions”, and the polemics that have accompanied it, we offer two ways in which the ethics of such a move can be evaluated. We provide multinational executives with two applications of ethics to inversion: Kant’s deontological theory and the consequentialist perspective of utilitarianism.  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

There are important synergies for the next generation of ethical leaders based on the alignment of modified or adjusted mental models. This entails a synergistic application of moral imagination through collaborative input and critique, rather than “me too” obedience. In this article, we will analyze the Milgram results using frameworks relating to mental models (Werhane et al., Profitable partnerships for poverty alleviation, 2009), as well as work by Moberg on “ethics blind spots” (Organizational Studies 27(3):413–428, 2006), and by Bazerman and Chugh on “bounded awareness” (Harvard Business Review, 2006; Mind &; Society 6:1–18, 2007) Using these constructs to examine the Milgram experiment, we will argue that the ways in which the experiments are framed, the presence of an authority figure, the appeal to the authority of science, and the situation in which the naïve participant finds herself or himself, all create a bounded awareness, a narrow blind spot that encourages a climate for obedience, brackets out the opportunity to ask the moral question: “Am I hurting another fellow human being?” and may preclude the subject from utilizing moral imagination to opt out of the experiment. We will conclude that these forms of almost blind obedience to authority are correctable, but with difficulty. We will argue that linking the modification of mental models to an unbinding of awareness represents an important synergistic relationship and one that can build effectively on the lessons learned from our experience with moral imagination.  相似文献

In this paper, I discuss the current project to converge the IASB and FASB conceptual frameworks, specifically efforts to purge the converged framework of concepts that hinder the promotion of balance sheet valuation using fair values. I discuss why I believe these efforts to be misguided, based on how investors who analyze financial statements employ accounting information. I focus on stewardship, reliability, and earnings — terms either demoted in importance or at risk of being eliminated in the framework convergence project. I explain their salience to financial statement users and argue against their deletion or demotion.  相似文献

This article contributes to the debate on skill-biased technical change by studying the dynamics of skill supply and wage inequality in an endogenous growth model with ability-biased technical progress. Due to a discouragement effect, rising within groups inequality reduces incentives to become educated for ordinary-ability workers. This mechanism generates a non-monotonic relationship between the growth rate and skill supply driving wage inequality upward during periods of accelerating technical change. This theoretical explanation is consistent with the apparent ambiguous relationship between the relative skill supply and inequality in the last decades in several OECD countries.  相似文献

Design and problem solving are central to technology and have distinguished learning in technology from other curriculum areas. This research investigated how expert technologists learn design and problem solving through experience. Data was collected from four expert technologists and this information was analysed using learning theories that focus on learning through experience—that is experiential learning theory, situated cognition, distributed cognition and activity theory. This framework of analysis provided evidence that learning through experience is central to these experts’ development and justify a broader construct of experience than normally associated with hard materials. This information supports curriculum development in hard materials technology that employs a wide range of experiences and provides justification for curriculum developers and teachers to justify, inform and develop effective design and problem solving learning programmes focussed on a broadened construct of experience.  相似文献

As apartheid gave way to political freedom in South Africa in the last quarter of the 20th century, chartered accounting firms began to hire black South African trainees for the first time. The study examines the oral histories of black chartered accountants within the context of social closure theory and South Africa’s changing political and ideological landscape. The evidence indicates that processes of professional closure and credentialing excluded the majority population from the ranks of the profession on basis of race and class throughout the period 1976–2000.  相似文献
