Price Effects on Compound Commodities

We examine the effect of simultaneous price changes on the total demand for a group of goods, which we call a compound commodity. Specifically, we consider unit and proportional cost components (e.g., taxes, transportation costs) imposed on compound commodities. If the unit cost is positive, then the proportional cost raises the relative price of the more expensive good, and thus induces substitution towards the less expensive good within this group. Then, the substitution effect of the proportional cost for a compound commodity is non‐negative if and only if the compound commodity and the other goods are, on average, not strongly substitutable.     

To Empower or Not to Empower? Multilevel Effects of Empowering Leadership on Knowledge Hiding

It is widely acknowledged that knowledge hiding persists and has detrimental effects in service organizations. With organizations increasingly becoming team based, understanding the interactions between supervisor and team members especially how team- and individual-level empowering leadership behaviors influence followers’ knowledge hiding is important. Using data on 527 followers from 60 departments in 19 Chinese hotels, the study proposes a multilevel model to examine the manifestation of two types of empowering leadership (individual-focused and differentiated empowering leadership) and the dual-level processes on followers’ knowledge hiding. Results show that differentiated empowering leadership is positively related to followers’ knowledge hiding via group relational conflict, whereas individual-focused empowering leadership is negatively related to followers’ knowledge hiding via their psychological safety. In addition, follower’s psychological safety buffers the positive relationship between group relational conflict and followers’ knowledge hiding. We discuss the implications on both theory and practice of empowering leadership on knowledge hiding.     

The puzzle of greenhouse gas footprints of oil abundance

The present inquiry lays a groundwork for the analysis of the net greenhouse gas (GHG) footprint of oil in the oil-abundant settings. To address the research question, the study puts forward a three-sector decision model, which provides a common ground for the assessment of the interaction of the structuralist and institutional factors influencing environmental pollution in the oil-reliant economies. The study shows that fossil-fuel abundance triggers forces, which induce diametrically opposed effects concerning atmospheric pollution. These are the rising carbon-intensive oil extraction and processing and fossil-fueled power generation versus shrinkage of the carbon-intensive manufacturing and growth of the low-carbon tertiarization. The theoretical analysis enables compartmentalization of the essential factors, which determine GHG emissions in the respective countries. To assess the significance of the proposed theoretical framework, the study employs multivariate panel co-integration techniques and two-stage fixed effects estimations for a dataset of 38 oil-producing countries for the time period between 1960 and 2018. In contrast to the existing literature, this study drives apart from the black box approaches that employ just one omnibus variable, per capita income.

基于模糊多属性群决策的维护方式选择研究

维护方式选择是维护管理中的重要工作之一,合理的维护方式既能达到保障设备的稳定运行,又能同时兼顾其它各个方面的要求。由于对维护方式的评价涉及多个部门、人员和属性,有些指标只是一个模糊的概念,因而采用模糊多属性群决策的方法对维护方式进行优先抉择。本文结合A公司的设备维护方式选择问题,尝试使用模糊多属性群决策折衷算法求解最佳的维护方式。

Perceptions of the benefits of the A3 planner in facilitating project-based learning in accounting education

This paper evaluates ways of instilling project management skills into accounting-based learning by the use of an iterative A3 planner to plan, monitor and review assignment progress. The application of an A3 planner to facilitate a project-based learning (PBL) group assignment in undergraduate accounting education has been critically evaluated in terms of both the student and tutor experience. The study uses a mix of qualitative and quantitative data. Quantitative data assisting exploration of perceptions were collected through 100 undergraduate students. A series of focus group discussions were carried out to investigate students’ engagement and tutors’ teaching experiences regarding the adoption of the A3 planner. The results suggest that the A3 planner promotes active planning and effective management of a PBL group assignment. It makes students’ thought processes more visible thereby facilitating and enhancing the tutoring/mentoring process. Moreover a more interactive and transparent approach by doing assignment via the use of an iterative A3 planner has ensured more feedback points and action based efficiency in the doing approach for learners.

为了指标而竞争*——来自中国煤矿企业的证据#br#

中国矿难治理取得了不可忽视的成就，但总结其成功经验的研究尚显不足。本文认为安全生产的总量指标控制是一种降低中国煤矿企业矿难死亡人数的有效方式。笔者手工搜集了2002—2006年中国煤矿企业矿难死亡人数和省级安全生产控制考核数据，并与工业企业数据库进行匹配，发现单个煤矿事故死亡人数和同地区其他煤矿事故死亡人数之间显著负相关，说明企业间存在指标竞争现象。广义双重差分回归结果显示，在控制指标越少的省份，企业间指标竞争越激烈。异质性分析发现，在超标省份或者主管官员晋升的关键时期，指标竞争更加激烈。最后，单个煤矿企业死亡人数与异省邻市矿难死亡人数不相关，排除了矿难导致监管加强的“威慑效应”。本文的研究结果表明，煤矿安全生产总量指标控制对企业安全生产有显著作用。
