Document Summary

Econ 2300 summer 2011 mark melatos. Topic 7 pricing with market power june 30. Firms charge each consumer their maximum wtp i. e. their reservation price. A consumer may purchase many units of a good over a period of time. Sat wtp declines with the # units purchased. Faced with such declining wtp, a firm may charge different prices for different. Groups of consumers have different d curves. If the firm can identify these: how much output should it produce in total, how much should it sell to each group? that, mr = mc in each market, mrs are the same in each market. Solution: total output must be divided between the groups of consumers such. An alternative way for a firm with monopoly power to extract consumer surplus. But as the consumer wants at a specific price: the specific per-unit usage fee (p). We can always find a sufficiently low p such that: More earned from each unit sold.

Suppose you are a manager of a firm that produces products X, Y and Z. You know that there are two different types of consumers, type 1 and type 2, who value your products differently. You also know that there 10,000 type1 consumers and 50,000 type 2 consumers with the following valuations for the three products:<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Consumer Type Product X Product Y Product Z 1 $250 $150 $100 2 $200 $75 $250

(a) If you price each product separately (i.e., using a standard pricing strategy), what prices should you charge to maximize revenues and what are the revenues?

(b) If you adopt a first-degree price discrimination policy, what prices should you charge to maximize revenues and what are the revenues?

(c) If you use a commodity-bundle strategy such that the products are sold as one item (i.e., you market product X, product Y, and product Z together), what price should you charge to maximize revenues and what are the revenues?
