Abstract

Recent supply disruptions catapulted the issue of risk in global supply chains (GSCs) to the top of policy agendas and created the impression that shortages would have been less severe if GSCs had been either shorter and more domestic or more diversified. But is this right? We start our answer by reviewing studies that look at risks to and from GSCs and at how GSCs have recovered from past shocks. We then look at whether GSCs are too risky, starting with business research on how firms approach the cost-resilience trade-off. We propose the risk-versus-reward framework from portfolio theory as a good way to evaluate whether anti-risk policy is justified. We then discuss how exposures to foreign shocks are measured and argue that exposure is higher than direct indicators imply. Finally, we consider the future of GSCs in light of current policy proposals and advancing technology before pointing to the rich menu of topics for future research on the risk-GSC nexus. Expected final online publication date for the Annual Review of Economics, Volume 14 is August 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
风险和全球供应链:我们知道什么和我们需要知道什么
最近的供应中断使全球供应链(GSCs)的风险问题成为政策议程的首要问题,并给人一种印象,即如果GSCs更短、更本土化或更多样化,短缺就不会那么严重。但这对吗?我们通过回顾研究GSCs的风险以及GSCs如何从过去的冲击中恢复来开始我们的回答。然后,我们从企业如何处理成本-弹性权衡的商业研究开始,研究gsc是否风险过大。我们提出了投资组合理论中的风险与回报框架,作为评估抗风险政策是否合理的好方法。然后,我们讨论了如何衡量对外国冲击的敞口,并认为敞口高于直接指标所暗示的。最后,我们根据当前的政策建议和先进的技术考虑了gsc的未来,然后指出了未来研究风险- gsc关系的丰富主题。《经济学年度评论》第14卷的最终在线出版日期预计为2022年8月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。
