基于DEA方法的广东科技与金融结合效益评价

本文采用数据包络分析方法(DEA)对全国各省、市、自治区金融投入与科技产出结合的效益进行评价,并对DEA测评结果进行深入分析,发现影响广东科技与金融结合效益的主要原因是金融投入的结构与科技产出的阶段不相协调以及金融投入资源的管理效率较低,从而为广东探索科技与金融结合的路径与对策选择提供决策依据。     

Financial networks,bank efficiency and risk-taking

Networks with a core–periphery topology are found in many financial systems across different jurisdictions. Though the theoretical and structural aspects of core–periphery networks are clear, the consequences that core–periphery structures bring for banking efficiency stand as an open question. We address this gap in the literature by providing insights as to how the structure of financial networks can affect bank efficiency. We find that core–periphery structures are cost efficient for banks, which is a characteristic that encourages the participation of banks in financial networks. On the downside, we also show that core–periphery structures are risk-taking inefficient, because they imply higher systemic risk levels in the financial system. In this way, regulators should be aware of the excessive risk inefficiency that arises in the financial system due to individual decisions made by banks in the network.     

Climate change adaptation: Is there a role for intervention research?

While climate change will expose regions to similar impacts, the extent of those impacts and effective response at the local level will be determined not only by the location's sensitivity and vulnerability but also by local groups and individuals’ capacity, including their institutional links, social networks and motivation to action. In parallel, scientific information and research plays a critical role in informing climate change adaptation by providing both an improved understanding of the actual climate risks and response alternatives.The paper focuses on two local-scale intervention research projects undertaken in urbanised coastal areas in Brazil and in Australia concentrated on improving the dialogue between ‘those who make science’ and ‘those who use science to make decisions’ in order to make climate science more useful, and creating purposeful collective action, respectively. A conceptual model is devised to investigate how intervention research could aid adaptive capacity by generating new knowledge and facilitating change towards climate change adaptation at the local level. Drawing on the findings, a framework is proposed to advance the role of intervention research in policy development for enhancing adaptive capacity.     

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.     

Hotel efficiency: A bootstrapped metafrontier approach

This paper introduces the metafrontier concept to account for the environmental and technological differences between various hotels groups. The interesting feature of the model is that it ensures that heterogeneous hotels are compared based on one homogenous technology. We test the model using a panel data sample of 78 Taiwanese hotels. The results clearly indicate that the size, ownership, and classification of a particular hotel have a significant impact on its efficiency. More implications of the results are provided.     

MUTUAL FUND PERFORMANCE EVALUATION – APPLICATION OF SYSTEM BCC MODEL

For the first time, this research adopts the system BCC model in data envelopment analysis in order to evaluate mutual fund performance and compares the results between the BCC model and the system BCC model. This study is based on the sample of stock funds and balanced funds in Taiwan, with the empirical results summarised as follows. (i) Under the system BCC model, the average score of balanced funds is greater than the average score of stock funds. (ii) There is a significant difference in efficiency scores between the BCC model and the system BCC model, and it is proper to adopt the system BCC model. (iii) The number of major reference sets that have been referenced under the BCC model is larger than under the system BCC model. (iv) If we neglect the distinctions between stock funds and balanced funds, there will be errors on performance assessment. Ultimately, the results reveal that there is a significant difference between the two models. Provided no consideration is made for the funds belonging to two different systems, errors in performance evaluation are inevitable. This research provides investors with both a more accurate and comprehensive evaluation method.     

The Management of Market-Oriented Economies: A Comparative Perspective

The 1981 reform of the Chilean pension system was revolutionary at its time. It was the first instance of a mature public Pay-As-You-Go social security system being converted into a mandatory defined contribution system managed by the private sector. This paper contends that a unique confluence of events were responsible for this change. The rise of a dictatorship in Chile, a struggling public retirement system, and a cadre of Chicago oriented economists determined to make Chile a model free market neoliberal economy. This was later followed by the Washington Consensus and the promotion of Chilean reform by the World Bank. This paper analyzes the Chilean reform and its subsequent development; evaluating it on both efficiency and equity grounds. While the evidence for efficiency gains is mixed there is little doubt that equity has suffered under the new system. Nevertheless, it continues to evolve and equity concerns are increasingly being addressed.     

公平和效率为导向的内部控制信息披露方式的转变

自《萨班斯--奥克斯利法案》颁布以来,美国上市公司内部控制信息披露方式由自愿性披露转变为强制性披露。而在2008年我国五部委联合发布的《企业内部控制基本规范》标志着我国上市公司内部控制信息也开始向强制性披露方式转变。论文试图用经济学的公平与效率理论分析内部控制信息由自愿性披露方式转变为强制性披露方式背后的原因,经过分析发现披露方式的转变是促进资本市场效率向保障资本市场公平的转变。     

Innovation and efficiency: It is possible to have it all

A firm that simultaneously engages in a high degree of both innovation and efficiency follows an approach that is often referred to as an ambidextrous strategy. Surprisingly, relatively few firms are able to balance these two emphases. Internal battles for resources often tip the scales in favor of efficiency over innovation, or vice versa. Management gurus frequently warn that simultaneously pursuing both can set the firm up for mediocre performance, yet the turbulent nature of today’s markets and cut-throat competition create a renewed need for firms to reconsider this dual approach for longer-term success. Unfortunately, practical insights from empirical studies regarding performance benefits and implementation issues are still scant. Perhaps this is one reason why few firms are successful in both efficiency and innovation. In this article, we provide evidence—using a cross-industry survey of senior marketing managers in publicly-traded U.S. firms—that firms which successfully employ an ambidextrous strategy outperform those which overemphasize either efficiency or innovation. Furthermore, we highlight marketing’s role as an example of the often overlooked need for successful functional implementation. Finally, we provide useful methods for managers to answer three key questions: (1) Is my firm ambidextrous?; (2) Should my firm be ambidextrous?; and, if so (3) How can my firm become ambidextrous?
