Sustainability adrift: An evaluation of the credibility of sustainability information disclosed by public organizations

This article aims to evaluate the credibility of information disclosed by public organizations in terms of sustainable development. It focuses on an under-studied aspect in the sustainability reporting literature—namely, the factors that may affect the credibility of disclosure practices. The study is based on a qualitative analysis of the sustainable development content of annual management reports disclosed by 113 ministries and public bodies in the province of Quebec, Canada. The findings shed more light on the main factors that affect the credibility of the information disclosed therein, particularly in terms of lack of transparency and flawed monitoring mechanisms.     

Identifying airline cost economies: An econometric analysis of the factors affecting aircraft operating costs

This paper provides the results of an econometric analysis of the influences of airline characteristics on the average operating costs per aircraft movement. The analysis combines a comprehensive selection of airline-output variables, airline-fleet variables, and airline-market variables. The results confirm the existence of economies of density, economies of load factor, economies of aircraft utilisation and economies of aircraft size. The paper does not provide evidence of economies of scale, economies of stage length or economies of fleet commonality. Furthermore, airlines that additionally operate full freighters, airlines that are members of a worldwide alliance and airlines that operate a multi-hub system face higher average operating costs per aircraft movement. Surprisingly, the regression results demonstrate that airlines that use newer aircraft have higher average operating costs per aircraft movement, suggesting that ownership costs (depreciation and leasing costs) of new aircraft outweigh the increasing maintenance costs of old aircraft. Finally, the results show that airlines that have a dominant position at their hubs or bases have higher operating costs per aircraft movement, implying that the absence of serious competitive pressure enables airlines to charge higher ticket prices and, with that, leads to a limited focus on cost savings.     

The power of design: How does design affect consumers’ online hotel booking?

Emphasizing experiential appeals to consumers through design is most notable in the emerging lifestyle hotel segment of the lodging industry. This study identifies which lodging design mechanisms evoke consumer responses and provides a novel understanding of the relationships among consumer perception of hotel product/service design and booking intention by incorporating consumer emotional arousal and quality expectations in a theoretical model. The findings of this study suggest that aesthetics and symbolism in hotel design shape booking intention through emotional arousal and quality expectation. The functional dimension of design affects booking intention only through quality expectation. The findings will be particularly meaningful to the lodging industry because online booking requires both emotional and cognitive responses on the part of consumers.     

商业信用与合作型客户关系的构建——基于提供给大客户应收账款的经验证据

利用我国上市公司前5名应收账款欠款人信息以及前5名大客户信息的披露数据,本文较为直接地考察了企业是否以及如何利用应收账款的产品质量担保功能与大客户构建合作型客户关系。研究结果表明,客户集中度越高,企业提供给大客户的信用政策越宽松,即应收账款金额越多,信用期限越长;进一步研究发现,在与主要客户地理位置相似度较低的企业、处于竞争性行业的企业以及营商环境较好的地区,上述两者之间的正相关关系有所增强。最后,本文发现,在与大客户构建合作型客户关系时,企业向这些大客户提供的应收账款越多,企业的业绩越好。     

Price and quality decisions in a vertically-differentiated supply chain with an “Online-to-Store” channel

Because of the prevalence of “Online-to-Store (OS)” channel, customers can purchase differentiated products online and pick up in-store. We develop a Stackelberg game-theoretic model to study the impact of an OS channel on quality levels, demands, prices, and profits of a manufacturer and a retailer in a supply chain. We assume that the retailer acts as a Stackelberg leader, and the manufacturer acts as a Stackelberg follower. The manufacturer produces and sells two products with vertically-differentiated quality levels to the retailer who in turn sells the products to customers through a Store channel, an Online channel, or an OS channel. The retailer incurs a handing cost if the OS channel is available, and consumers bear a shipping cost and a transaction cost when the products are purchased from the Online and Store channels, respectively. We find that the manufacturer should reduce both products’ quality levels and wholesale prices, whereas the retailer can increase the selling prices for a relatively small shipping cost and a not too small handling cost. When the products are available both online and in-store, however, the quality levels, wholesale prices and selling prices might increase for a small shipping cost and a not too small handling cost. Compared to the case in which both products are available online only with the OS channel, adding the Store channel is always beneficial for both parties. The intuition behind these results hinges on the trade-off between the handling cost and the increased market demand for the retailer. Moreover, the quality levels, the wholesale prices of both products, and the selling price of the low-quality product would decrease, while the selling price of the high-quality product increases for a sufficiently low transaction cost and a not too small shipping cost.     

Multiple equilibria in the Aghion–Howitt model

We show that the simple Aghion–Howitt model exhibits oscillatory indeterminacy in the process of creative destruction as firms undertaking new research do not internalize their effect on existing firms. A simple calibration shows that indeterminacy occurs for quite plausible parametrizations of the share of the intermediate good.     

区域中心城市创新生态圈要素架构、生态特征与运行机制

区域中心城市创新生态圈以生物学为隐喻，注重发挥创新主体的能动作用，能够放大区域中心城市发展优势。在回顾创新生态圈理论渊源的基础上，界定区域中心城市创新生态圈内涵，明确创新生态圈要素构成；以企业聚集发展为逻辑起点，探讨区域中心城市创新生态圈生态特征；基于生态学、创新理论等跨学科知识，构建区域中心城市创新生态圈演进模型，探究其运行机制。研究认为，区域中心城市创新生态圈具有开放式协同、动态自调节、多样性共生、自组织演化等生态特征，其运行机制由协同共生机制、风险识别与防控机制、利益分配机制和环境匹配机制共同组成。
