has
a.some influence over the wages paid to crew members but no influence over the price
of salmon.
b.some influence over the price of salmon but no influence over the wages paid to crew
members.
c.some influence over both the price of salmon and the wages paid to crew members.
d.no influence over either the price of salmon or the wages paid to crew members.

19) Table 22-23
The town of Franklin is facing a severe budget shortage. The town administrator has
proposed four options to balance the budget: increase property taxes (taxes), cut the
school arts budget (arts), turn off half of the streetlights in the town (streetlights),
reduce police patrols (police). Exactly one of the four choices will prevail, and the
choice will be made by way of pairwise voting, with the majority determining the
outcome on each vote. The preferences of the voters are summarized in the table below.
Voter Type
Refer to Table 22-23. If the town administrator asks the people to first choose between
cutting the arts program and turning off half of the streetlights, and then choose
between the winner of the first election and reducing police patrols, and then choose
between the winner of the second election and increasing taxes, which option will win
each vote?
20) Consider the markets for mobile and landline telephone service. Suppose that when
the average income of residents of Plainville is $55,000 per year, the quantity demanded
of landline telephone service is 12,500 and the quantity demanded of mobile service is
28,000. Suppose that when the price of mobile service rises from $100 to $120 per
month, the quantity demanded of landline service decreases to 11,000. Suppose also
that when the average income increases to $60,000, the quantity demanded of mobile
service increases to 33,000.
Using the midpoint method, what is the income elasticity of demand for mobile
service?
