The recent financial crisis has prompted much new research on the interconnectedness of the modern financial system and the extent to which it contributes to systemic fragility. Network connections diversify firms' risk exposures, but they also create channels through which shocks can spread by contagion. We review the extensive literature on this issue, with the focus on how network structure interacts with other key variables such as leverage, size, common exposures, and short-term funding. We discuss various metrics that have been proposed for evaluating the susceptibility of the system to contagion and suggest directions for future research. (JEL D85, E44, G01, G21, G22, G23, G28)

Abstract While financial crises can be triggered by several causes, runs on short-term liabilities are at the heart of all financial crises, with the recent 2007–09 financial crisis being no exception. Given the unpredictability of crisis triggers and the overwhelming predictability of short-term funding’s role in financial crises, legislative and regulatory responses to the recent financial crisis should focus on the consequences of relying on short-term funding in the financial system. However, in addressing the problem of such funding, it is important to recognize the social benefits afforded by short-term liabilities and not simply the costs. To this end, this paper provides a brief overview of short-term funding in the U.S. financial system, while also highlighting the trade-off between the costs and benefits of short-term liabilities. The paper proceeds with an analysis of various proposals aimed at addressing the short-term funding issue.

Purpose – The purpose of this paper is to provide a cohesive review of the major findings in the literature concerning the Global Financial Crisis. Design/methodology/approach – Papers published in top-rated finance and economics journal since the crisis up to the present were reviewed. A large number of these were selected for inclusion, primarily based on the number of citations they had received adjusted for the amount of time elapsed since their publication, but also partly based on how well they fit in with the narrative. Findings – Much has been done to investigate the causes of the Global Financial Crisis, its effects on various aspects of the financial system, and the effectiveness of regulatory measures undertaken to restore the financial system. While more remains to be done, the existing body of research paints an interesting picture of what happened and why it happened, describes the interrelationships between the mortgage markets and financial markets created by the large scale securitization of financial assets, identifies the problems created by these inter-linkages and offers possible solutions, and assesses the effectiveness of the regulatory response to the crisis. Originality/value – This study summarizes a vast amount of literature using a framework that allows the reader to quickly absorb a large amount of information as well as identify specific works that they may wish to examine more closely. By providing a picture of what has been done, it may also assist the reader in identifying areas that should be the subject of future research.

This article examines the role of Islamic Law in convergence to western corporate governance features in Pakistan. The recent financial crisis in the world highlighted the importance of good corporate governance features. This phenomenon highlighted the possibility of adopting an alternative to conventional financial system in Pakistan. Islamic finance has shown its presence in the wake of financial crisis in the world. Therefore, this articles analyses, in comparative perspective, the Islamic financial system viz a viz conventional financial system. It further analyses the possibility of convergence of corporate governance mechanism, which is key for good governance in any financial system, in Pakistan. It concludes that Islamic Financial System may be adopted as alternative financial system as well as corporate governance mechanism may be converged to western corporate governance features in Pakistan. However, while doing so Islamic norms may act as a litmus test which may not be as problematic as it appears at first sight.

AbstractWe develop a conceptual asset-based framework of credit creation based on three leading variables: (i) the amount of assets acceptable as collateral, (ii) the level of leverage and (iii) the level of trust. As credit expands along these dimensions in a non-linear dynamic, the financial system becomes more liquid. At the same time, it becomes more prone to endogenous feedbacks and vulnerable to internally generated instabilities manifested as booms and busts. Applying this framework to the global financial crisis, we show that the subprime crisis was both a signature and only one possible trigger in an increasingly unstable financial system. Using historical data, we demonstrate a significant shift in the components of US bank balance sheets and a decoupling of bank assets from deposits since the mid-1980s, marking the rise of “securitized-fractional reserve banking”. The subsequent decades were a period of growing leverage, with debt-securities assuming money-like functions and serving as collateral for further credit creation. As trust began to recede, the high levels of leverage were no more viable, precipitating a reduction of the amount of assets acceptable as collateral, and leading to a contraction in credit and to liquidity spirals. We discuss the potential general applicability of this framework of credit creation and define extensions in future research.

Purpose – The purpose of this paper is to analyse the emergence, operation and features of the time banks that were created during the recent financial crisis in Greece as grass-roots initiatives of different communities, and to examine their relation to the concept of “co-production” and possible relevance to foresight. Time banks are particularly interesting for the future of services: they address all sorts of services while the time-bank “value” of these different types of services does not necessarily reflect their actual value in the free market; impacts may spread from the mere coverage of people’s needs, to increased social capital and community empowerment; and some scholars consider them as flexible forms of co-production, or even as enablers of wider social change. The purpose of the paper is to examine the emergence, and features of the time banks created during the recent financial crisis in Greece as grass-roots initiatives. Design/methodology/approach – Primary information and data were gathered through eight extensive face-to-face interviews with key members of the four time banks based on a semi-structured questionnaire. The methodology also included desk research and review of the information included in time banks’ websites. The selection of these four time banks was based on the fact that they are the most active ones in Athens, which is the capital of the country gathering around 40 per cent of the Greek population and presenting the severest consequences of the financial crises in terms of unemployment, poverty, shutdown of businesses, share of people with no insurance, etc. Findings – Based on a specific analytical framework summarising the available literature, the Greek time banks are compared with each other but also in relation to the findings in the literature, where some interesting differences emerge. The paper also explores the role that foresight can plan in the development of alternative initiatives like time banks. The interesting conclusion is that foresight can help time banks as much as time banks can help foresight in upgrading its processes to deal with challenges of the twenty-first century. Research limitations/implications – The research focuses on the four most active time banks in Athens. While this selection is justified, future research would be good to include all the time banks in Greece. Social implications – The paper explores how time banks in Greece emerged as well as how they can further develop. This is of direct relevance to society as time banks are by default a community initiative. Originality/value – Time banks in Greece have not been previously studied. Second, time banks in general were never linked to approaches like foresight. This becomes increasingly important in examining possible approaches toward more sustainable and resilient societies.

The extant literature suggests that one of the main causes of the recent financial crisis was the excessive use of short-term debt by banks. Using a large sample of banks, we find that increases in repurchase agreements (repos) were recognized by external capital markets to increase bank risk in the pre-crisis period. In the crisis, we find a negative relationship between repos and risk. We attribute this result to evidence suggesting that “good” banks were able to continue funding their repos, whereas “bad” banks had to significantly decrease their repo funding.

The globalization of finance in recent years and the concurrent growth in the financial sector's influence, manifested most dramatically in the recent financial crisis, highlights the importance for political scientists of understanding the political economy of global finance. The authors review six important books that are representative of recent thinking by political scientists on the topic. They address the central questions that have been at the heart of the literature on global finance from its beginning in new and interesting ways. The most important developments highlighted in this article are the move from a predominant focus on state-centered patterns of regulation to the consideration of transnational governance regimes that mix public and private regulation; the effort to understand the causal forces that shape the political economy of global finance by allowing for an interaction among interests, institutions, and ideas; and giving increased attention to new sources of systemic risk in the global financial system, as well to the consequences for domestic politics of interactions with the global financial system. Notwithstanding the progress that has been made in coming to grips with the political economy of global finance, the authors highlight a number of questions that need to be addressed in future research. Although various nonstate actors have been recognized as important in the constitution of the rules of global finance, it is also necessary to understand the behavior of the actors who enact these rules. It is also important to generate evidence that forges some agreement on the causes of the globalization of finance, especially as the arguments made become more complex. Finally, there is a need for a more realistic assessment of the costs and benefits of financialization at the global and national levels. This last challenge is essential for a thorough understanding of the current global financial crisis.

Supply chain risk management (SCRM) has increasingly become a more favored research area for academicians and practitioners in recent years. SCRM has been considered an important source of competitive advantage and as an effective method of reducing vulnerability in supply chain systems. Supply chain risk and uncertainty and their related potential losses are becoming much larger as the frequency of natural disasters, political and economic instabilities, and unexpected events is gradually rising up in the past decade. The latest earthquake and the subsequent tsunami in Japan along with the current global economic and financial crisis remind us once again the urgent needs for effective risk management in today’s global supply chains. The purpose of this paper is to contribute to an updated and complete understanding of current research on supply chain risk management (SCRM) in such highly uncertain and unstable natural and economic environments. In addition, we also aimed to provide ideas and identify potential research questions and directions for future research.

NOTE: THIS ARTICLE WAS PUBLISHED WITH THE INFORMING SCIENCE INSTITUTE. Aim/Purpose................................................................................................................................................................................................. The main objective of the current study is to develop a business model for service providers of cloud computing which is designed based on circular economy principles and can ensure the sustainable consumption. Background Even though the demand for cloud computing technology is increasing day by day in all over the world, the current the linear economy principles are incapable to ensure society development needs. To consider the benefit of the society and the vendors at the same time, the principles of circular economy can address this issue. Methodology................................................................................................................................................................................................. An extensive literature review on consumption, sustainable consumption, circular economic, business model, and cloud computing were conducted. the proposed model of Osterwalder, Pigneur and Tucci (2005) is admitted designing the circular business model. Contribution................................................................................................................................................................................................. The proposed model of the study is the contribution of this study where provides the guidelines for the cloud computing service providers to achieve both their economic profits and the society’ needs. Findings Finding reveals that if the cloud computing service providers design their business model based on the “access” principle of circular economy, they can meet their economic profits and the society’ needs at a same time. Recommendations for Practitioners.............................................................................................................................................................. It is recommended to the startup and the existing businesses to utilize the proposed model of this study to reach a sustainable development. Recommendation for Researchers................................................................................................................................................................ It proposes a new circular business model and its linkages with community building. Impact on Society............................................................................................................................................................................................ The proposed model of the study provides guidelines to the cloud computing service providers to design a business model which is able not only to meet their economic profit, but also to meet the society’s and customers’ benefits. Future Research............................................................................................................................................................................................... Future researches can build on this research model which proposed in this study to examine the limitations of this model by using empirical researches.
