1.In the short run a competitive firm maximizes its profits by choosing an output at which price is equal to short run marginal cost.

In the long run a competitive firm maximizes its profits by choosing an output at which price is equal to short run marginal cost.

2.Price is determined by the market and Output level is the only choice the firm has to make. Since firms want to maximise profit, it will produce at a level where Marginal Cost equals Marginal Revenue. This is the profit maximisation point

monopoly never increases its production to the level which makes the demand inelastic.

3.Both produce at the efficient quantity and maximize total surplus. Their last good is produced where price equals marginal cost.

In terms of total surplus, one could argue that they are both equally beneficial to society. However, in p-d monopoly, all the surplus is producer surplus; there is no consumer surplus. So one could also argue that
