External shocks and efficiency changes in the US airline industry

The US airline industry has experienced severe turbulence during the recent decade. The September 11 terrorist attack (9/11) was the greatest shock at the beginning of the 2000s. Recently, the dramatic increase in fuel costs emerged as another shock to the industry. To understand the effects of these two major events, this study investigated the cross-sectional efficiency of the US airline industry and its changes using the data envelopment analysis technique. The primary findings suggest that 9/11 affected the network carriers (NCs) more severely than the low-cost carriers (LCCs), while fuel costs more seriously influenced the LCCs than the NCs.     

如何让思想政治工作贯穿当前的国家燃油税改革

Private Regulation to Appropriate Value from Design Innovations: Implications for Anti-trust Policy

Co-operative ventures among rivals are looked upon in general with suspicion by antitrust authorities. In this paper, we position ourselves in the school of thought that evaluates collusive behavior among rivals with the Schumpeterian concept of dynamic competition in mind rather than the concept of Neoclassical perfect competition. We argue that whenever firms have difficulty in appropriating sufficient returns from their innovations, certain forms of apparently collusive behavior--or, more precisely, 'private regulation'--may actually stimulate investment in innovation and thereby Schumpeterian competition. A study of firms' strategies to appropriate value from design innovations in the Dutch and Italian furniture industry illustrates our arguments.     

Consumer eco‐innovation adoption: assessing attitudinal factors and perceived product characteristics

For business and environmental reasons, increased understanding of green consumer behavior is essential. This paper addresses consumer adoption and non‐adoption of a high involvement eco‐innovation (the alternative fuel vehicle, AFV). The purpose is to integrate two research streams to explore factors driving and hindering adoption. The factors are rooted in environmental psychology research and the diffusion of innovation literature. Survey results on Swedish car owners are reported. The results indicate that adopters and non‐adopters differ on norms, attitudes, novelty seeking and on how innovation attributes are perceived. Furthermore, the results show that the groups rank car attributes such as fuel consumption and carbon dioxide emissions differently. The main contribution of the paper is the integration of norms and attitudes together with consumer adoption factors in analyzing green consumer behavior in relation to a high involvement product. The implications for business and marketing strategy and for environmental policy are discussed. Copyright © 2010 John Wiley & Sons, Ltd and ERP Environment.
