在BSV模型下矫正投资者对信息的认知偏差

Barberis、Shleifer和Vishny(1998)基于投资者认知市场信息过程中出现的心理偏差，解释了过度反应和反应不足现象，并在BSV模型的框架下，进一步引入了一个心理矫正中介来矫正投资者对市场信息的认知偏差。通过建立市场管理者与中介机构之间的委托一代理体制，发现确实有可能存在此类中介。市场管理者可以制定出一套针对此类中介的最优激励机制，对其进行监督管理。

Research agenda for low-carbon mobility: Issues for New World cities

ABSTRACT

Low-carbon mobility (LCM) features strongly in debates about the sustainability of cities and their resilience in the face of demographic, economic, and climate change. Transport is a major source of carbon emissions and there are indications that these continue to increase, despite the considerable recent advances in vehicle, engine, and fuel technologies. Reducing carbon emissions from transport may become more difficult, not easier. A particular issue relates to the New World cities, typified by those of North America and Australasia, which largely developed from the latter half of the nineteenth century onward and whose transportation systems were largely based around private vehicle ownership and usage. These cities are typically composed of low-density, dispersed suburbs, which are highly car dependent and resource and carbon emission intensive. This article develops a research agenda directed at determining and testing policy and planning measures relevant to the quest for low carbon mobility in New World cities. It suggests a rich agenda for essential research on LCM. Much of this agenda falls within the realm of the integration of transport and land use, with attention to urban design details to enhance the perceptions of and opportunities to use low carbon transport alternatives. Research topics identified for LCM research include (1) urban design and land use–transport integration (LUTI), (2) low carbon mobility policies directed at achieving widespread behavior change, (3) opportunities for new technology and its application, including requirements for systems and infrastructure, and (4) analysis and tools for informed decision making, including modeling, measurement, visualization, and especially assessment.     

Energy benchmarking in support of low carbon hotels: Developments,challenges, and approaches in China

Achieving effective and objective energy benchmarking for hotels is integral in fostering the sustainable development of the lodging sector. In this work, we reveal the major and minor streams of hotel energy benchmarking and ascertain that the most popular approach in benchmarking is normalized energy use intensity (EUI) based on floor level. Previous efforts to establish EUI indicators using subsystem average, data envelopment analysis (DEA), and regression technique are also studied. We propose that hotel energy benchmarking based on floor area is useful from the top-down management perspective. However, on a practical perspective, energy benchmarking based on facilities should be the first priority for hotel management or owners. Compared with the general energy benchmarking in the building sector, we find that the hotel sector lags behind in the adoption of computer modeling for benchmarking.     

Environmental scanning the future of event design

This paper used multiple sources of information in order to identify the forces likely to impact event design. Content analysis of key informant interviews and selected trade publication articles identified key forces impacting event design. Technology, the environment and green issues, security and safety, and globalization were forces identified by both the key informants and the trade literature. Neither of the sources gave much attention to political forces. This article contributes to our understanding of the forces impacting event design and suggests some environmental scanning methodologies that can be used with both key informants and the trade publication literature.     

Moderating effect of capital intensity on the relationship between leverage and financial distress in the U.S. restaurant industry

During the recent and ongoing economic turmoil, countless businesses have been facing financial distress and many have filed for bankruptcy. This issue is especially critical for the restaurant industry due to restaurants’ sensitivity to economic fluctuations. Therefore, the purpose of this study is to examine the financial distress issue in the U.S. restaurant industry. In particular, the study examines a moderating effect of capital intensity on the relationship between a firm's leverage and degree of financial distress. The dataset includes publicly traded U.S. restaurant firms during the period 1990–2008. The study measures the degree of financial distress by modified Z-scores, and findings suggest a positive moderating effect of capital intensity on the relationship between leverage and financial distress.
