Interconnectedness

This paper reviews tools used to identify and measure interconnectedness and raises the awareness of policymakers as to potential cross-sectional implications of prudential tools aimed at controlling interconnectedness. The paper examines two sets of tools—developed at the IMF and externally—to identify the implications of interconnectedness in systemic risk and how these tools have been applied in IMF surveillance. The paper then proposes a preliminary framework to analyze some key internationally-agreed-upon and national prudential tools and finds that while many prudential tools are effective in reducing interconnectedness, the interaction among these tools is far less clear cut.

Financial sector linkages have increased continuously in the Caribbean with cross border capital flows and financial conglomerates dominating the financial system. While the greater interconnectedness can heighten systemic risks and likelihood of contagion, it can have positive impacts provided the regional authorities take steps to prevent the systemic risk. In this context, financial sector reform measures aimed at bolstering and harmonizing prudential regulations in line with international best practices, the strengthening and enhancement of financial sector supervision to include cross border linkages through consolidated supervision, increased cooperation across supervisors in the region, and the establishment of deposit insurance and crisis resolution frameworks will be critical to maintain financial sector stability and minimize the repercussions of any negative shocks.

This relatively simple model attempts to capture and integrate four widely held views about financial crises. [1] Interconnectedness among financial institutions (banks) can play a major role in precipitating systemic financial crises. [2] Lack of information about the quality of bank portfolios also plays a role in precipitating systemic crises. [3] Financial crises, particularly systemic ones, are often followed by severe, lengthy recessions. [4] Loss of confidence in the financial system is partly responsible for the length and severity of these recessions. In the model, banks make decisions about initiating and liquidating risky loans. Interconnectedness among their asset portfolios can obscure information about these portfolios, causing them to make inefficient decisions about liquidation, and about retention of the managers who assess credit risk. These decisions can increase the depth of recessions, and they can produce systemic financial crises. They can also reduce the effectiveness of future bank risk assessment, increasing the probability of lengthy, severe recessions. The government, acting in the interest of current and future depositors, may wish to increase the transparency of bank portfolios by limiting interconnectedness. The optimal degree of regulation, which may depend on depositors’ degree of risk aversion, may not eliminate financial crises.

Plucked from a humble nomad family to become the leader of one of Tibet’s oldest Buddhist lineages, the young Seventeenth Karmapa draws on timeless values to create an urgent ethic for today’s global community. We have always been, and will always be, interconnected—through family, community, and shared humanity. As our planet changes and our world grows smaller, it is vital we not only recognize our connections to one another and to the earth but also begin actively working together as interdependent individuals to create a truly global society. The Karmapa, Ogyen Trinley Dorje, is uniquely positioned to guide us in this process. Drawing on years of intensive Buddhist training and a passionate commitment to social issues, he teaches how we can move from a merely intellectual understanding to a fully lived experience of connection. By first seeing, then feeling, and finally living these connections, we can become more effective agents of social and ethical change. The Karmapa shows us how gaining emotional awareness of our connectedness can fundamentally reshape the human race. He then guides us to action, showing step by step how we can change the way we use the earth’s resources and can continue to better our society. In clear language, the Karmapa draws connections between such seemingly far-flung issues as consumer culture, loneliness, animal protection, and self-reliance. In the process, he helps us move beyond theory to practical and positive social and ethical change.

We analyze the determinants of IMF lending since the early nineties, a period during which the roles of financial cycles and interconnectedness as amplifiers and transmitters of economic crises have gained prominence. First, we show that the global financial cycle is an important driver of IMF lending cycles. Second, using a panel of 91 advanced, emerging, and frontier economies over 1992-2014, we show that global factors and interconnectedness, as proxied by a countries’ potential exposure to economic spillovers from trade partners, together with more traditional idiosyncratic factors, have a significant impact on the probability that a member country obtains financial assistance from the IMF. Our results are robust to various robustness checks. The approach presented in this paper can be used to assess future demand for IMF financial assistance.

This book explores the nature of COVID-19 through posing four questions: What could be said to be the cause of COVID-19? Who is likely to be infected? Where is infection likely to take place? When is infection likely to occur? It will demonstrate that these four W questions are interconnected, that they are the very ones which pre-occupy biomedicine today, whether in the form of clinical medicine or epidemiology. Epidemiology is often portrayed as “sub-standard”, while clinical medicine is put on a pedestal, marked as “superior” and “methodologically impeccable/privileged”. This book challenges this standard assessment. It argues that the causal model underpinning epidemiology is more adequate to account for medical data and evidence, across the board. Epidemiological Thinking is Medical Thinking, which this book calls Ecosystem Thinking and, through it, explores the values underpinning Medical Thinking, including geopolitical values.

Examines the political discourse behind tourism, presenting some questions regarding the tensions associated with the interconnections. This title focuses on deterritorialisation and the development of fresh regionalisms, paying specific attention to collaborative efforts in tourism development.

This volume provides an introduction to and overview of the emerging field of interconnected networks which include multilayer or multiplex networks, as well as networks of networks. Such networks present structural and dynamical features quite different from those observed in isolated networks. The presence of links between different networks or layers of a network typically alters the way such interconnected networks behave – understanding the role of interconnecting links is therefore a crucial step towards a more accurate description of real-world systems. While examples of such dissimilar properties are becoming more abundant – for example regarding diffusion, robustness and competition – the root of such differences remains to be elucidated. Each chapter in this topical collection is self-contained and can be read on its own, thus making it also suitable as reference for experienced researchers wishing to focus on a particular topic.
