Global Supply Chains

Question A:

Firms’ incentives to reduce costs by sourcing inputs and products abroad have caused many European industries to become more vulnerable to supply chain disruptions.

Responses weighted by each expert's confidence

Question B:

Private firms have inadequate incentives to make investments to reduce the risk that disruptions in the supply of imports will cause shortages and raise domestic prices.

Responses weighted by each expert's confidence

Question C:

Prioritisation of efficiency over resilience in global supply chains makes current disruptions likely to continue beyond 2022.

Responses weighted by each expert's confidence

There has also been a lot of domestic fragmentation. Domestic chains (like toilet paper or meat in the US) have also been disrupted by COVID

Probably, but from British experience supply chain crisis can also be domestic, so that international supply helps to resolve these.
