Studying the level-effect in conjoint analysis: An application of efficient experimental designs for hyper-parameter estimation

Research in marketing, and business in general, involves understanding when effect-sizes are expected to be large and when they are expected to be small. An example is the understanding of the level-effect in marketing, where the effect of product attributes on utility is positively related to the number of levels present among choice alternatives. Knowing when consumers are sensitive to the competing levels of attributes is an important aspect of merchandising, selling and promotion. In this paper, we propose a model and a method for studying the level-effect in conjoint analysis. The model combines perceptual theories in psychology to arrive at a non-linear specification of hyper-parameters in a hierarchical model. The method applies an experimental design criterion for efficient estimation of hyper-parameters. The proposed model and method are validated using a national sample of respondents.      

Multi-Stakeholder Labour Monitoring Organizations: Egoists,Instrumentalists, or Moralists?

This article examines four leading multi-stakeholder labour monitoring organizations. All operating in the maquiladora industry, these organizations are viewed in light of the growing global trend toward industry self-regulation, or what has been referred to as the ‘global out-sourcing of regulation’. Their Board compositions, codes of conduct and monitoring and enforcement strategies are all examined as a means of tentatively positioning these organizations along an ‘egoist-instrumentalist-moralist’ ethical culture continuum. Such a framing provides insights into the perceived salience of these organizations’ broader stakeholders, the effectiveness of codes of conduct on workplace practices more generally, and the role that ethics plays in the governance and accountability of these increasingly important types of organizations. Jeff S. Everett teaches financial accounting at the University of Calgary's Haskayne School of Business. Along with his research on maquilas, Jeff conducts research in the areas of professional ethics, environmental accounting, and accounting education. Dean Neu is a professor of accounting at the Haskayne School of Business. His research examines how accounting numbers play a crucial role in shaping public perceptions and public policy. Currently a research assistant at the Haskayne School of Business. Daniel Martinez is examining issues related to fair trade, corruption, and economic development in indigenous communities.     

When should entrepreneurs expedite or delay opportunity exploitation?

We theorize on the performance implications of the timing at which entrepreneurs stop exploring their business opportunities and start exploiting them. Using an optimal-stopping approach, we characterize the time when exploitation should begin based primarily on when an entrepreneur's ignorance has been sufficiently reduced through knowledge accumulation. This “ignorance threshold” captures a tradeoff between the time needed to increase legitimacy and the necessity to act now to minimize competition. Changes in legitimacy and competition are based on how entrepreneurs manage their knowledge (tacit versus explicit) under differing degrees of novelty for the business opportunity. These changes, in turn, impact the performance and timing of opportunity exploitation.     

船载雷达光轴晃动对修正参数标定的影响

船载雷达标校望远镜光轴、标校电视光轴在天线不同状态下会产生不同程度的晃动,可达角分量级,在利用反向法标定雷达零位和轴系误差时,会给标定结果带来较大误差。针对此问题,提出了通过分别检测天线在正向、反向状态下标校望远镜光轴与标校电视光轴间不平行度以判定光轴是否存在晃动的方法,同时提出了利用大地测量成果精确解算光轴俯仰晃动量的方法,给出了解算模型,试验表明解算精度满足雷达标校要求。在此基础上给出了当光轴存在俯仰晃动时,俯仰零位、俯仰光电偏差、天线重力下垂误差等相关参数标定的改进数据处理模型。     

Mid-level Managers,Organizational Context,and (Un)ethical Encounters

This article details day-to-day ethics issues facing MBAs who occupy entry-level and mid-level management positions and offers defined examples of the stressors these managers face. The study includes lower-level managers, essentially excluded from extant literature, and focuses on workplace behaviors both undertaken and observed. Results indicate that pressures from internal organization sources, and ambiguity in letter versus spirit of rules, account for over a third of the most frequent unethical situations encountered, and that most managers did not expect to face those issues. Various contextual factors accounted for 32% of the organizational factors that affected decisions. We discuss implications for the workplace, especially the unique ethics challenges for newer managers.     

The age-effect of financial indicators as buffers against the liability of newness

This paper builds on the liabilities of newness literature to suggest that accounting information is important for new firms. Using a sample of over 30,000 companies followed during their first 7 years of existence, we find evidence that financial indicators mitigate the liability of newness and that this buffering effect is stronger the younger the organization. These results represent three primary contributions to the literature. First, our conceptualization of accounting measures as indicators of external (creditworthiness enhancing legitimacy) as well as internal (targets for management) buffers to the liabilities of newness provides a novel way of viewing these constructs and explains why they are important to new firms despite their uncertainty and opacity. Second, we theoretically justify and empirically validate that these constructs are more important the younger the new firm is, which runs counter to the common wisdom of these constructs in the entrepreneurship literature. Third, we identify buffers against failure for new firms that are generalizable across industries.     

Robust Poverty and Inequality Measurement in Egypt: Correcting for Spatial-price Variation and Sample Design Effects

The paper estimates inequality and absolute poverty in Egypt for 1997 with measures that are robust to sample design effects and corrected for spatial variation in price levels. Standard errors for inequality indices are calculated using a bootstrap approach which replicates the sample design. Standard errors for poverty indices are corrected for the design effects resulting from sample stratification and clustering. The authors use data from the Egypt Integrated Household Survey and follow the cost‐of‐basic‐needs methodology to construct region‐specific poverty lines. It is found that 15.7 million people were poor in Egypt in 1997, or 26.5% of the population. The estimates indicate a sharp sectoral difference with rural areas being significantly poorer, but significant differences in poverty were not found between Upper and Lower Egypt. This finding differs substantially from the conventional wisdom that Upper Egypt is poorer than Lower Egypt and results from the correction for spatial‐price variation.     

Cross Guarantees And Negative Pledges: A Preliminary Analysis

Deregulation of Australia's commercial trading environment during the 1980s spawned two major financial instruments for company groups: negative pledge and class order deed of cross guarantee. Both instruments were premised on the pari passu or creditor equality principle. If is informative for the future analysis of those financial instruments to consider their background, their commercial features and interconnections. Also, it is crucial to consider the connection between the old NCSC Class Order Deed of Indemnity and the newer AS C Deed of Cross Guarantee. This article provides preliminary evidence on the incidence of the new deed relative to its predecessor. It also considers the costs and benefits of the Deed of Cross Guarantee, including the illusory nature of the quid pro quo protections provided to creditors in return for allowing "closed-group" companies to gain accounting and auditing relief from statutory reporting requirements.
