12) George and Jerry are competitors in a local market. Each is trying to decide if it is
better to advertise on TV, on radio, or not at all. If they both advertise on TV, each will
earn a profit of $3,000. If they both advertise on radio, each will earn a profit of $5,000.
If neither advertises at all, each will earn a profit of $10,000. If one advertises on TV
and the other advertises on radio, then the one advertising on TV will earn $4,000 and
the other will earn $2,000. If one advertises on TV and the other does not advertise,
then the one advertising on TV will earn $8,000 and the other will earn $5,000. If one
advertises on radio and the other does not advertise, then the one advertising on radio
will earn $9,000 and the other will earn $6,000. If both follow their dominant strategy,
then George will
a.advertise on TV and earn $3,000.
b.advertise on radio and earn $5,000.

17) Scenario 17-6
Assume that a local telecommunications company sells high speed internet access and
cable television. The company's only two customers are Taylor and Tim. Taylor is
willing to pay $50 per month for high speed internet access and $50 per month for cable
television. Tim is willing to pay only $20 per month for high speed internet access, but
is willing to pay $70 per month for cable television. Assume that the
telecommunications company can provide each of these products at zero marginal cost.
Refer to Scenario 17-6. If the telecommunications provider is able to use tying to price
high speed internet access and cable television, what is the profit-maximizing price to
charge for the "tied" good?

preferences are summarized in the table.
Refer to Table 22-25. The travelers decide to conduct pairwise voting with the majority
determining the outcome of each vote to decide their next move. If they first choose
between going left and going right, and then choose between the winner of the first vote
and going straight, which direction will they go?
