Ways to strengthen supply-chain resilience 

There are three ways firms can make their input supplies more resilient, and only one of them requires government involvement. 

1]. Re-shoring production from developing countries: One option is to re-shore production from developing countries. COVID-crisis, by increasing the relative costs of supply chains, has accelerated a re-shoring trend that began with the 2008-09 global financial crisis. Supply chains have become more expensive. The price of containers used to ship goods from Asia to the West have risen eightfold. 

• Re-shoring means to transfer a business operation that was moved overseas back to the country from which it was originally relocated. 

2]. Creation of large inventories: A second way for firms to insure against supply-chain shocks is to create large inventories. 

3]. Diversification of input sources: Companies can dual-source or even triple-source inputs, relying on suppliers from different continents to counter the risk. But this diversification strategy has its limits. For example, a highly specialized supplier that invests in research and development for a specific input is not easily replaceable. 

• Heavy regional concentrations of suppliers also make diversification difficult. Most producers of chips, battery cells, rare earth materials and pharma ingredients are based in Asia.
