Chapter 5: Q4. (page 114)
"The problem with our democratic institutions is that they don't correctly reflect the will of the people! If the people鈥攔ather than self-interested politicians or lobbyists鈥攈ad control, we wouldn't have to worry about the government taking actions that don't maximize allocative and productive efficiency." Critique.
Short Answer
If the people had control over decision-making for the market, the action might not always maximize the allocative and productive efficiency because of the market failures.
