Greening transportation fleets: Insights from a two-stage game theoretic model

The greening of organizational transportation fleets, especially trucks and automobiles, has gained increasing attention by companies in a variety of industrial sectors. The reasons for this concern and attention are due to regulatory and competitive pressures, but also increasing costs of fossil-fuels. Surprisingly the amount of research and modeling for fleet management overall has been rather limited, with the focus on managing green vehicle investments virtually non-existent. In this study we develop a two-stage game theoretic model that helps evaluate, from both policy and organizational perspectives, the implications of greening of transportation fleets. Various parameters are evaluated including factors such as innovations in green vehicle technology, levels of service differences, cost of fuel, adjusting tax policy, regulatory compliance requirements, and adaptation costs. This evaluation provides practical insights into actions that could be considered by regulators and organizations to encourage environmental investments.     

A network-based analysis of the impact of structural damage on urban accessibility following a disaster: the case of the seismically damaged Port Au Prince and Carrefour urban road networks

The magnitude 7.0 earthquake that struck Haiti in January 2010 led to an unprecedented effort in collecting and providing geographical information in support of humanitarian aid. Although most of the compiled datasets and generated maps were able to provide specific and detailed information regarding the location of damaged buildings and road interruptions, none or little information was available to describe the accessibility—or otherwise—of the urban space. Here we try to offer an alternative method to define the urban accessibility landscape in the aftermath of earthquake damage, by combining simple graph theory concepts and GIS-based spatial analysis to assess how the urban space accessibility decreases when the road network is damaged.     

基于企业理论的“农民工”权益保护研究

随着农村劳动力的过剩,很多农民选择了城市务工,但是损害农民工权益的现象屡屡发生。研究"农民工"权益在企业的保护方案,首先要解决企业理论与"三农"政策的内在一致性。从原有企业理论出发,可以建立社会网络产业结构信息系统、各地区各行业"农民工"权益信息系统,给不同区域企业与"农民工"传递"农民工"权益及其变动信息,保护"农民工"的权益。     

证券市场监管理论——公共利益论、部门利益论的比较与评述

对经典的监管理论,尤其是对公共利益论、部门利益论与捕获论形成的背景、内涵、优缺点、适用条件进行了完整的比较分析,认为这些理论观点对监管的研究和监管实践有着重要的指导意义,但每一种理论都是对监管的某一方面进行的研究,还没有一种理论能够对证券市场监管的所有问题做出满意的解释。要提高我国证券市场监管的效果,需要从整体上运用这...

EXPLAINING FIRM CAPITAL STRUCTURE: THE ROLE OF AGENCY THEORY VS. TRANSACTION COST ECONOMICS

The study of capital structure has increasingly gained importance in strategic management research. Paradigms derived from organizational economics have also gained popularity in explaining firm actions. Agency theory and transaction cost economics represent two such paradigms that rely on the notion of market imperfections. Notwithstanding the similarities between them, these two offer different explanations of the role of debt and equity in a firm. The governance abilities of the financing structures and the nature of assets of the firm provide two key sources of differences. Viewing capital structure from transaction cost economics gives rise to predictions that are contradictory to those presented by agency theory. It is argued that the extant evidence mainly supports the transaction cost viewpoint. Two organizational phenomena—leveraged buyouts and product diversification—are used to highlight the comparison.

Resident perceptions of the impacts of P2P accommodation: Implications for neighbourhoods

Although a research base is beginning to emerge in relation to the peer-to-peer accommodation phenomenon, the voices of residents are seldom heard in this scholarly literature. This study uses Social Exchange Theory to examine resident perceptions regarding the impact of P2P accommodation growth, and specifically Airbnb, on their neighbourhood. Fifty-one semi-structured interviews were employed to illuminate understanding of how resident perceptions are formed in relation to the exchange relationship with Airbnb guests. Findings reveal a dominance of negative perceptions of socio-economic and environmental impacts. The study also contributes a typology of residents, based on their perceptions and behaviour towards associated impacts, which may guide policymakers and practitioners towards the adoption of an anthropocentric approach on P2P accommodation. The study concludes with a discussion of theoretical and practical implications.
