Responses
Responses weighted by each expert's confidence
Question B:

Responses
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.

Firms always have an incentive to reduce costs. Globalisation increased dependence on imported inputs and this has increased vulnerability.

No strong externalities. One problem is that many have inconsistent plan Bs: relying on the same supplier, if something happens.
