Question C: Private unbacked crypto assets serve no important economic purpose.

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.

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.
