When the government enforces a price ceiling on a good, which is lower than the current market price, _________.
a perfectly competitive firm produces less
a monopoly firm produces more
When the government enforces a price ceiling which is below the market price, a perfectly competitive firm produces less because the profit maximization quantity is lesser at that price level. For a monopoly firm, at the reduced price, the profit-maximizing quantity is actually greater than it was at a higher price. Hence production increases.
