1. The profit maximizing output level for a monopolist with constant marginal cost is at a price and quantity combination where the Lerner Index is maximized.

2. The degree of homogeneity of the production function determines the relationship between marginal and average cost, given the firm is minimizing total cost in the long-run.

3. There are four standard government policies that create a deadweight loss (in perfectly competitive markets) and each of the goals associated with these policies could be achieved with the same policy that has no deadweight loss.

4. The change in equilibrium price following an increase in the wage rate will be smaller, the more elastic demand and supply are.

谢谢大家哈～ 还有能帮我详细解释下　deadweight loss 么　一直也没太搞明白还有它和政府（决策）有啥关系？
