Answer to Question 1
In a perfectly competitive market, the lack of entry barriers ensures that the market price is ultimately driven down to minimum average cost in the long run. However, if there are barriers to entry in a market, new firms will find it difficult to enter, reducing the downward pressure on price. This will allow the existing firms to earn economic profits in the long run. As long as these barriers exist, firms can sell goods at a price that is above average total cost.
