How might an black market interfere with efficient allocation of resources?

A black market interferes with the efficient allocation of resources by circumventing legal regulations and market mechanisms, leading to mispricing and distortion of supply and demand. This can result in essential goods being allocated to those willing to pay the highest price, rather than those who need them most. Additionally, black markets can foster uncertainty and risk, discouraging legitimate businesses from participating in the market, ultimately leading to inefficiencies and reduced overall economic welfare.
