A performance evaluation model for international tourist hotels in Taiwan—An application of the relational network DEA

This research utilizes relational network data envelopment analysis to construct a model to analyze the efficiency and effectiveness of international tourist hotels (ITHs) in Taiwan. The different production processes within the hotel are evaluated, as well as the relationships between efficiency, effectiveness, and overall performance. Finally, based on the results, we recommend ways of enhancing the overall performance of the hotel industry in Taiwan.

金融危机救助方案与成本分担机制分析

各国政府应对本轮金融危机的救助虽取得一定成效,但仍然引发了关于救助方案的选择和救助成本等相关问题的探讨。英美等发达国家的救助基本遵循了依靠市场或私人机构进行救助,政府尽量不采取直接的干预,以减少政府救助成本。资产负债表重构这一救助方式能将救助成本分担到私人机构,在合适的条件下应用,可以降低救助道德风险发生的可能性,并且极大地减少政府的救助成本。     

内部控制、治理环境与投资者保护

本文研究了内部控制质量对投资者保护的影响,以及不同治理环境对内部控制治理功能的影响。研究发现:内部控制质量的提高,或更为充分的内控信息披露有助于抑制大股东资金占用,有助于抑制经理人与股东之间的代理成本;治理环境越差的地区,内部控制治理效应越高。这说明,对于投资者保护较弱的地区,内部控制可能成为补偿弱投资者保护负面影响的一种替代机制。本文研究意味着,近年来推出的内部控制相关制度起到了积极的效果;此外,完善上市公司内部控制,对于治理环境较差、投资者利益得不到有效保障的地区显得尤为重要。

Separating what we eat from where: Measuring the effect of food away from home on diet quality

Many argue that food away from home (FAFH) is a contributing factor to the obesity epidemic, showing that body mass index and consumption of FAFH are positively correlated. However, correlation analyses using a simple regression approach, such as the Ordinary Least Squares (OLS), do not prove that FAFH causes weight gain. We use a first-difference estimator to establish a causal relationship between FAFH and dietary intakes. Using dietary recall data from the 2003–2004 National Health and Nutrition Examination Survey and the 1994–1996 Continuing Survey of Food Intakes by Individuals, we find that FAFH does indeed increase caloric intake and reduce diet quality, but that the effect is smaller than if estimated using OLS. Thus, models based on associations are likely biased upward, as much as 25% by our estimates.     

基于交易成本理论的工程合同类型与交易成本探讨

工程合同类型选择问题在工程实践中研究较为广泛,然而对于该问题的更深层次的探讨,特别是在经济学领域的探索却相对较少。在经济学理论影响社会显著发展的当今,应用经济学理论探讨社会经济问题是十分必要的。论文以新制度经济学中交易成本理论研究成果为基础,通过对交易成本的重新理解,分析其与不同合同类型问的联系,得到具有一定指导性的结论,有助于进一步研究和探索。     

东北地区产业结构变化对经济增长贡献的实证研究

东北地区是建国初期我国优先发展重工业的重点地区。改革开放后,我国进行经济体制改革,区域产业结构进行了相应调整,东北地区产业结构随之改变,失去了工业发展优势,经济增长速度放缓。经过产业结构调整,东北地区的产业结构趋向合理,促进了地区经济增长。     

Underwriter reputation,earnings management and the long‐run performance of initial public offerings

This study contributes to the extant literature on the nature of earnings management surrounding initial public offerings (IPOs) by investigating the role of underwriter reputation. We argue that prestigious underwriters will protect their reputation by carefully monitoring and certifying financial information on IPO firms, thereby limiting any potential earnings manipulation. As a result, those IPO firms that are associated with more prestigious underwriters are likely to exhibit substantially less‐aggressive earnings management. Conversely, we find the existence of a negative relationship between earnings management and the post‐offer performance of an IPO firm’s stocks only for those firms associated with less‐prestigious underwriters.     

Corporate Hedging Policy and Equity Mispricing

We show that firms’ use of derivatives is negatively associated with stock mispricing. This result is consistent with the notion that hedging improves the transparency and predictability of firms’ cash flows resulting in less misvaluation. Furthermore, we show that the negative relationship between mispricing and hedging is particularly strong when market value is below fundamental value, which is consistent with prior evidence that hedging has a positive impact on firm valuation. Finally, we provide evidence that a “spread‐out” hedging policy that entails the use of a variety of derivative contracts can be more effective in reducing mispricing.
