1. Suppose that resale is impossible (very high resale cost for example). Solve for the profitmaximizing outcome under 3rd degree price discrimination. 2. Now suppose that you cannot charge different prices to different groups of consumers (legal restriction or cost-less resale). What is the profit-maximizing outcome?
