This paper examines the effect of various types of bank capital on the profitability and efficiency of conventional and Islamic banks. Our results show that higher quality forms of capital improve the profitability and efficiency for both systems although the results are stronger for conventional banks. The capital effect is more pronounced for large, too-big-to-fail, and highly capitalized banks. The results are robust across various subsamples, alternative profitability and efficiency measures, and different estimation techniques. 相似文献

This paper studies direct systems of finite, that is with finitely many agents, communication structures, finite (balanced and superadditive) NTU games and finite economies. The inductive limit of such a system is again a communication structure, an NTU game or an economy, this time possibly with infinitely many agents. As a matter of fact, each infinite communication structure, each infinite NTU game and each infinite economy, is the inductive limit of a direct system of finite communication structures, finite NTU games and finite economies. A communication game is an NTU game with a communication structure on the set of players. To each economy, there corresponds a balanced and superadditive NTU game. To each economy with a communication structure on the set of agents, there corresponds a communication game. In the paper it is proved that the core of the inductive limit of a direct system of communication games is not empty and in fact the intersection of the cores of the finite communication games of the direct system. It follows that each infinite economy (with or without a communication structure on the set of agents) has a nonempty core. A direct system of economies is a generalisation of the Debreu and Scarf [Debreu, G., Scarf, H. A limit theorem on the core of an economy, International Economic Review 4, pp. 235–246.] example of `replica economies'. The proof of the nonemptiness of the core of the inductive limit of a direct system of economies is along the lines of the proof by Debreu and Scarf. As by-product it is shown that an NTU game is totally balanced if and only if all its finite subgames are balanced. 相似文献

Food quality ratings can be used for product differentiation and strategic marketing. This article develops a differentiation measure based on the cross‐entropy of two distributions for speciality coffees. It examines whether quality ratings achieve their objectives for speciality coffee supply chains. The estimation, using e‐auctions data, indicates that the quality rating is more informative in the Cup of Excellence (CofE) relative to the Q auction. To determine significance, a statistical test for comparing the information measure across different e‐auctions and segments of the quality rating was developed. The significant difference between the two auctions is not a surprise as the auctions trade coffee lots of different volumes and the quality evaluation is more important in the case of the CofE, with its jury of renowned coffee experts. The total cross‐entropy measure of product differentiation shows that the 100‐point quality rating does not carry the same information content and meaning in the two different e‐auctions and their respective supply chains. The cross‐entropy measure of product differentiation is shown to be a good indicator of the information and the value created throughout the speciality food supply chain. 相似文献

This study reports on an investigation into what lies behind a firm's first export order and revisits the questions posed in the classic article by Simmonds and Smith [(1968). British Journal of Marketing, 2, 93–100]. It concentrates on risk/reward considerations in decision-making. Interviews were undertaken with owner/managers who were the key decision-makers in 10 newly internationalising UK start-up firms, that is, in their first year of operation, in order to avoid recollections in respect of hindsight. The findings highlight that a variety of factors can affect the decision of owner/managers in small firms to start their internationalisation path. Decisions are made in the context of perceived risk/reward considerations regarding exploiting various opportunities; for example, what are considered to be affordable losses against respective owner/manager's objectives and experience. The contribution of the study is that it employs an effectuation lens in respect of the first export decision. 相似文献

Geoscientists are faced with a number of complexities that represent obstacles to the development of realistic simulation of deep earth processes. Realistic 4D thermo-mechanical simulation using software packages like Underworld and Gale, when combined appropriately with geoscientific expertise, can lead to novel insights into the deformation of geological structures at a wide range of time and spatial scales. The challenge for end-user geoscientists lies in applying their knowledge within the framework of the software’s input specification, including initial, internal, and boundary conditions and output visualization parameters. We have built a Graphical User Interface (GUI) to remove many of the difficulties related to editing the Extensible Markup Language (XML) encoded input files of Underworld/Gale geomodels and therefore, to greatly broaden the user base of these software packages. By helping Underworld/Gale to meet a large audience, we provide a tool to the geoscience community that helps to move from untested conceptual models to physically valid, properly scaled modelling. Furthermore, the UnderworldGUI offers a mechanism for storing and retrieving experimental models in a centralised database, thus providing the geoscience community with a means to share the outcomes of its experimental research. Further details of the UnderworldGUI are available at the web site http://www.wiki.vislab.usyd.edu.au/moinwiki/UnderworldGUI. 相似文献

This study examines whether IPO disclosure requirements mandated by countries’ securities laws are associated with variation in IPO underpricing in international IPO markets. Our empirical analysis uses a unique sample of 6,025 IPOs from 34 countries over the period from 1995 to 2002. We show for the first time that the stringency of disclosure requirements for IPO prospectuses is negatively associated with the extent of IPO underpricing, after controlling for various country‐ and firm‐level determinants of underpricing. Moreover, we find that the disclosure effect on IPO underpricing is moderated by the extent of a country’s capital market integration. Taken together, our findings are consistent with the view that increased disclosure regulation appears to reduce IPO underpricing and hence the cost of equity, and that institutional factors such as capital market integration play an important role in understanding the economic consequences of disclosure regulation in international IPO markets. 相似文献

In this Point–Counterpoint article we argue that institutional scholarship has become overly concerned with explaining institutions and institutional processes, notably at the level of the organization field, rather than with using them to explain and understand organizations. Especially missing is an attempt to gain a coherent, holistic account of how organizations are structured and managed. We also argue that when institutional theory does give attention to organizations it inappropriately treats them as though they are the same, or at least as though any differences are irrelevant for purposes of theory. We propose a return to the study of organizations with an emphasis upon comparative analysis, and suggest the institutional logics perspective as an appropriate means for doing so. 相似文献

This study provides insight into the dominant methodological practices that have shaped the field of negotiation over the
past four decades and sheds light on possible gaps and trade-offs. We content analyzed 941 peer-reviewed negotiation articles
(published between 1965 and 2004) and identified the most important methodological trends over time. The results reveal significant
changes in reliability, validity, and triangulation issues. In addition, the rise of multivariate statistics and multiple
data sources displays positive evolution towards more sophisticated methodologies. Despite these positive evolutions, we want
to encourage current and future researchers to conduct more longitudinal and qualitative research to further advance our knowledge
on negotiation. 相似文献
