1. A machine manufacturer sells high precision milling equipments. It sells the machine as well as the maintenance services. Users of milling machines from competitors were also potential sources of maintenance business. Based on a survey, customers were clustered into four segments of different size as shown below. Their willingness to pay for the machine and the maintenance service is also given in the table. The marginal cost to the firm for the machine and the maintenance services is respectively, $550 and $470, and there is no cost saving from bundling. segment Segment Size WTP for Machine WTP for maintenance 1 12 $1,250 $990 2 23 $1,450 $480 3 22 $1,180 $1,040 4 43 $1,390 $870 a. If the company uses component pricing, what are the optimal prices and the resulting profits for each item? b.

The industry marginal cost, excluding the cost of emissions (private marginal cost), is 4 + 4•q, expressed in $ per tire. The inverse demand curve for tires is p = 480 - 3-q, also expressed in $ per tire. In order to achieve the socially efficient level of tire production, which takes into account the optimal level of air pollution, the government levies a tax on the industry. What is the efficient pollution tax? $84 per tire $101 per tire $152 per tire Price
