Book Description
We estimate the role of (pre-Ukraine war) supply disruptions in constraining the Covid-19 pandemic recovery, for several advanced economies and emerging markets, and globally. We rely on two approaches. In the first approach, we use sign-restricted Vector Auto Regressions (SVAR) to identify supply and demand shocks in manufacturing, based on the co-movement of surveys on new orders and suppliers’ delivery times. The effects of these shocks on industrial production and GDP are recovered through a combination of local projection methods and the input-output framework in Acemoglu et al. (2016). In the second approach, we use the IMF’s G20 model to gauge the importance of supply shocks in jointly driving activity and inflation surprises. We find that supply disruptions subtracted between 0.5 and 1.2 percent from global value added during the global recovery in 2021, while also adding about 1 percent to global core inflation that same year.

Operations Rules
Author: David Simchi-Levi
Publisher: MIT Press
ISBN: 0262289024
Category : Business & Economics
Languages : en
Pages : 253
Book Description
An expert offers a set of rules that will help managers achieve dramatic improvements in operations performance. In recent years, management gurus have urged businesses to adopt such strategies as just-in-time, lean manufacturing, offshoring, and frequent deliveries to retail outlets. But today, these much-touted strategies may be risky. Global financial turmoil, rising labor costs in developing countries, and huge volatility in the price of oil and other commodities can disrupt a company's entire supply chain and threaten its ability to compete. In Operations Rules, David Simchi-Levi identifies the crucial element in a company's success: the link between the value it provides its customers and its operations strategies. And he offers a set of scientifically and empirically based rules that management can follow to achieve a quantum leap in operations performance. Flexibility, says Simchi-Levi, is the single most important capability that allows firms to innovate in their operations and supply chain strategies. A small investment in flexibility can achieve almost all the benefits of full flexibility. And successful companies do not all pursue the same strategies. Amazon and Wal-Mart, for example, are direct competitors but each focuses on a different market channel and provides a unique customer value proposition—Amazon, large selection and reliable fulfillment; Wal-Mart, low prices—that directly aligns with its operations strategy. Simchi-Levi's rules—regarding such issues as channels, price, product characteristics, value-added service, procurement strategy, and information technolog—-transform operations and supply chain management from an undertaking based on gut feeling and anecdotes to a science.

Handbook of Ripple Effects in the Supply Chain
Author: Dmitry Ivanov
Publisher: Springer
ISBN: 3030143023
Category : Business & Economics
Languages : en
Pages : 346
Book Description
This book offers an introduction to the ripple effect in the supply chain for a broad audience comprising recent developments. The chapters of this handbook are written by leading experts in supply chain risk management and resilience. For the first time, the chapters present in their synergy a multiple-faceted view of the ripple effect in supply chains, while considering organization, optimization, and informatics perspectives. Ripple effect describes the impact of a disruption propagation on supply chain performance, structural designs and operational parameters. The ripple effect manifests when the impact of a disruption cannot be localized and cascades along the supply chain. The resulting structural dynamics can lead to capacity and demand fulfilment downscaling and negatively influence the firm’s financial and operational performance. The book delineates major features of the ripple effect and methodologies to mitigate the adverse impact of supply chain disruption propagation and to recover in case of severe disruptions. The book provides fresh insights for supply chain management and engineering regarding the following questions: - In what circumstance does one failure cause other failures? - Which structures of the supply chain are especially susceptible to the ripple effect? - What are the typical ripple effect scenarios and what are the most efficient ways to respond them? Distinctive Features: • It considers ripple effect in the supply chain from an multi-disciplinary perspective• It offers an introduction to ripple effect mitigation and recovery policies in the framework of disruption risk management in supply chains for a broad audience• It integrates management and engineering perspectives on disruption risk management in the supply chain• It presents innovative optimization and simulation models for real-life management problems• It considers examples from both industrial and service supply chains• It reveals decision-making recommendations for tackling disruption risks in the supply chain in proactive and reactive domains.

The New (Ab)Normal
Author: Yossi Sheffi
Publisher: MIT CTL Media
ISBN: 1735766127
Category : Business & Economics
Languages : en
Pages : 271
Book Description
Much has been written about Covid-19 victims, how scientists raced to understand and treat the disease, and how governments did (or did not) protect their citizens. Less has been written about the pandemic’s impact on the global economy and how companies coped as the competitive environment was upended. In his new book, "The New (Ab)Normal", MIT Professor Yossi Sheffi maps how the Covid-19 pandemic impacted business, supply chains, and society. He exposes the critical role supply chains play in helping people, governments, and companies to manage the crisis. The book draws on executive interviews, pandemic media coverage, and historical analyses. Sheffi also builds on themes from his books "The Resilient Enterprise" (2005) and "The Power of Resilience" (2015) to enrich the narrative. The author paints a compelling picture of how the Covid-19 virus is changing many facets of human life and what our post-pandemic world might look like. This must-read book helps companies to redefine their business models and adjust to a fast-evolving economic landscape. The stage is set In Part 1 of the book, “What Happened,” the author looks at how companies fought to mend the global economic fabric even as the virus ripped more holes in it. Part 2, “Living with Uncertainty,” views the crisis through a supply chain risk management lens derived from Yossi Sheffi’s previous books. This perspective shows how companies create corporate immune systems to quickly recognize and manage large-scale disruptions. The ongoing pandemic is creating a new normal in life, work, and education—covered in Part 3, “Adjustment Required.” Consumer fears about the contagion as well as government mandates require businesses in industries such as retail, hospitality, entertainment, sports, and education to create “safe zones” for workers and customers. Many elements of the book – especially in Part 4, “Supply Chains for the Future” – show how the virus accelerated preexisting trends in technology adoption. China was the epicenter of the pandemic; it also was the first nation to be disrupted and recover. Part 5 of the book, “Of Politics and Pandemics,” explains why reports that companies are abandoning China in favor of other offshore manufacturing centers do not reflect reality. Fundamentally, The New (Ab)Normal is about businesses trying to create a better future in a time of extreme uncertainty – a point emphasized in Part 6, “The Next Opportunities.” The outlook is not necessarily gloomy. The advance of technology is accelerating, a trend that can level the playing field between small and large companies. Nimble small businesses are using a growing array of off-the-shelf cloud computing and mobile apps to deploy sophisticated technologies in their supply chains and customer interfaces. The New (Ab)Normal Another new normal is working from home. Remote working enables individuals to live anywhere and companies to recruit talent from anywhere. Education, especially higher education, faces a major disruption (and major opportunity) that is likely to shake the high-cost model of in-person education in favor of online or hybrid education. Regrettably, the book recognizes one trend accentuated by Covid-19--the growing inequality, and anticipates that the new normal will be more stratified.

After-Effects of the COVID-19 Pandemic: Prospects for Medium-Term Economic Damage
Author: Mr. Philip Barrett
Publisher: International Monetary Fund
ISBN: 1513587900
Category : Business & Economics
Languages : en
Pages : 23
Book Description
The COVID-19 pandemic has led to a severe global recession with differential impacts within and across countries. This paper examines the possible persistent effects (scarring) of the pandemic on the economy and the channels through which they may occur. History suggests that deep recessions often leave long-lived scars, particularly to productivity. Importantly, financial instabilities—typically associated with worse scarring—have been largely avoided in the current crisis so far. While medium-term output losses are anticipated to be lower than after the global financial crisis, they are still expected to be substantial. The degree of expected scarring varies across countries, depending on the structure of economies and the size of the policy response. Emerging market and developing economies are expected to suffer more scarring than advanced economies.

Supply Chain Disruptions
Author: Haresh Gurnani
Publisher: Springer Science & Business Media
ISBN: 0857297783
Category : Technology & Engineering
Languages : en
Pages : 339
Book Description
One of the most critical issues facing supply chain managers in today’s globalized and highly uncertain business environments is how to deal proactively with disruptions that might affect the complicated supply networks characterizing modern enterprises. Supply Chain Disruptions: Theory and Practice of Managing Risk presents a state-of the-art perspective on this particular issue. Supply Chain Disruptions: Theory and Practice of Managing Risk demonstrates that effective management of supply disruptions necessitates both strategic and tactical measures – the former involving optimal design of supply networks; the latter involving inventory, finance and demand management. It shows that managers ought to use all available levers at their disposal throughout the supply network – like sourcing and pricing strategies, providing financial subsidies, encouraging information sharing and incentive alignment between supply chain partners – in order to tackle supply disruptions. The editors combine up-to-date academic research with the latest operational risk management practices used in industry to demonstrate how theoreticians and practitioners can learn from each other. As well as providing a wealth of knowledge for students and professors who are interested in pursuing research or teaching courses in the rapidly growing area of supply chain risk management, Supply Chain Disruptions: Theory and Practice of Managing Risk also acts as a ready reference for practitioners who are interested in understanding the theoretical underpinnings of effective supply disruption management techniques.

ISBN: 9292621564
Category : Business & Economics
Languages : en
Pages : 737
Book Description
After a disappointing 2019, growth prospects in developing Asia have worsened under the impact of the current health crisis. Signs of incipient recovery near the turn of this year were quickly overthrown as COVID-19 broke out in January 2020 in the region’s largest economy and subsequently expanded into a global pandemic. Disruption to regional and global supply chains, trade, and tourism, and the continued spread of the outbreak, leave the region reeling under massive economic shocks and financial turmoil. Across Asia, the authorities are responding with policies to contain the outbreak, facilitate medical interventions, and support vulnerable businesses and households. Assuming that the outbreak is contained this year, growth is expected to recover in 2021. Especially to face down fundamental threats such as the current medical emergency, innovation is critical to growth and development. As some economies in developing Asia challenge the innovation frontier, many others lag. More and better innovation is needed in the region to sustain growth that is more inclusive and environmentally sustainable. Five key drivers of innovation are sound education, productive entrepreneurship, high-quality institutions, efficient financial systems, and dynamic cities that excite knowledge exchange. The journey to creating an innovative society takes long-term commitment and hard work.
