Anecdotal evidence suggests the existence of specific choke points in the global trade network revealed especially after natural disasters (e.g. hard drive components and Thailand flooding, Japanese auto components post-Fukushima, etc.). Using a highly disaggregated international trade database we assess the spillover effects of supply shocks from the import of specific goods. Our goal is to identify inherent vulnerabilities arising from the composition of a country’s import basket and to propose effective mitigation policies. First, using network analysis tools we develop a methodology for evaluating and ranking the supply fragility of individual traded goods. Next, we create a country-level measure to determine each country’s supply shock vulnerability based on the composition of their individual import baskets. This measure evaluates the potential negative supply shock spillovers from the import of each good.

Changing Patterns of Global Trade outlines the factors underlying important shifts in global trade that have occurred in recent decades. The emergence of global supply chains and their increasing role in trade patterns allowed emerging market economies to boost their inputs in high-technology exports and is associated with increased trade interconnectedness.The analysis points to one important trend taking place over the last decade: the emergence of China as a major systemically important trading hub, reflecting not only the size of trade but also the increase in number of its significant trading partners.

Politics is intuitively about relationships, but until recently the network perspective has not been a dominant part of the methodological paradigm that political scientists use to study politics. This volume is a foundational statement about networks in the study of politics.

"The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.

The global financial crisis of 2008/9 is the Great Depression of the 21st century. For many though, the similarities stop at the Wall Street Crash as the current generation of policymakers have acted quickly to avoid the mistakes of the past. Yet the global crisis has made room for mistakes all of its own. While governments have apparently kept to their word on refraining from protectionist measures in the style of 1930s tariffs, there has been a disturbing rise in "murky protectionism." Seemingly benign, these crisis-linked policies are twisted to favour domestic firms, workers and investors. This book, first published as an eBook on VoxEU.org in March 2009, brings together leading trade policy practitioners and experts - including Australian Trade Minister Simon Crean and former Mexican President Ernesto Zedillo. Initially its aim was to advise policymakers heading in to the G20 meeting in London, but since the threat of murky protectionism persists, so too do their warnings.

Assessing country risk is a core component of surveillance at the IMF. It is conducted through a comprehensive architecture, covering both bilateral and multilateral dimensions. This note describes some of the approaches used internally by Fund staff to examine a wide array of systemic risks across advanced, emerging, and low-income economies. It provides a high-level view of the theory and methodologies employed, with an on-line companion guide providing more technical details of implementation. The guide will be updated as Fund staff’s methodologies for assessing country risk continue to evolve with experience and feedback. While the results of these approaches are not published by the IMF for market sensitivity reasons, they inform risk assessments featured in bilateral surveillance as well as in the IMF’s flagship publications on global surveillance.

States of Fragility 2020 sets a policy agenda for fragility at a critical turning point: the final countdown on Agenda 2030 is at hand, and the pandemic has reversed hard-fought gains. This report examines fragility as a story in two parts: the global state of fragility that existed before COVID-19, and the dramatic impact the pandemic is having on that landscape.

This paper presents a simple heuristic measure of tail risk, which is applied to individual bank stress tests and to public debt. Stress testing can be seen as a first order test of the level of potential negative outcomes in response to tail shocks. However, the results of stress testing can be misleading in the presence of model error and the uncertainty attending parameters and their estimation. The heuristic can be seen as a second order stress test to detect nonlinearities in the tails that can lead to fragility, i.e., provide additional information on the robustness of stress tests. It also shows how the measure can be used to assess the robustness of public debt forecasts, an important issue in many countries. The heuristic measure outlined here can be used in a variety of situations to ascertain an ordinal ranking of fragility to tail risks.

This title provides a comprehensive introduction to the key issues in trade and liberalization of services. Providing a useful overview of the players involved, the barriers to trade, and case studies in a number of service industries, this is ideal for policymakers and students interested in trade.

How to prevent runs on open-end mutual funds? In recent years, markets have observed an innovation that changed the way open-end funds are priced. Alternative pricing rules (known as swing pricing) adjust funds’ net asset values to pass on funds’ trading costs to transacting shareholders. Using unique data on investor transactions in U.K. corporate bond funds, we show that swing pricing eliminates the first-mover advantage arising from the traditional pricing rule and significantly reduces redemptions during stress periods. The positive impact of alternative pricing rules on fund flows reverses in calm periods when costs associated with higher tracking error dominate the pricing effect.
