If they both advertise on TV, each will earn a profit of $10,000. If they both advertise on radio, each will earn a profit of $14,000. If neither advertises at all, each will earn a profit of $20,000. If one advertises on TV and other advertises on radio, then the one advertising on TV will earn $16,000 and the other will earn $6,000. If one advertises on TV and the other does not advertise, then the one advertising on TV will earn $30,000 and the other will earn $4,000. If one advertises on radio and the other does not advertise, then the one advertising on radio will earn $24,000 and the other will earn $8,000.

Table 17-5 The information in the table below shows the total demand for premium-channel digital cable TV subscriptions in a small urban market. Assume that each digital cable TV operator pays a fixed cost of $200,000 (per year) to provide premium digital channels in the market area and that the marginal cost of providing the premium channel service to a household is zero. -Refer to Table 17-5. Assume there are two digital cable TV companies operating in this market. If they are able to collude on the quantity of subscriptions that will be sold and on the price that will be charged for subscriptions, then their agreement will stipulate that

If a certain market were a monopoly, then the monopolist would maximize its profit by producing 4,000 units of output. If, instead, that market were a duopoly, then which of the following outcomes would be most likely if the duopolists successfully collude?

Table 17-3 Imagine a small town in a remote area where only two residents, Maria and Miguel, own dairies that produce milk that is safe to drink. Each week Maria and Miguel work together to decide how many gallons of milk to produce. They bring milk to town and sell it at whatever price the market will bear. To keep things simple, suppose that Maria and Miguel can produce as much milk as they want without cost so that the marginal cost is zero. The weekly town demand schedule and total revenue schedule for milk is shown in the table below: -Refer to Table 17-3. Suppose that Maria and Miguel work together in order to operate as a profit-maximizing monopolist. How many gallons of milk will be produced and sold?
