If clerical workers in your state voted to have a union represent them in negotiations with employers, they would have monopoly power in wage determination
Employers would be in no position to exert monopsony power in their employment of clerks in this market due to the large number of employers in the market. Labor supply is given by LS = 50W - 100 (or, equivalently W = LS/50 + 2 ) Labor demand is given by LD = 700 - 25W (or, equivalently W = -LD/25 + 28 ) a. What is the equation for marginal revenue? b. Using the supply and demand equations, compute the wage rate and number of workers that would be hired when there is no union representation. c. Using the supply and demand equations, compute the wage rate and number of workers hired when the union represents workers and acts to maximize aggregate wages to all workers hired. d. Explain the impact of (c) on the competitive market.
a.
Marginal revenue is given by MR = (-2/25 )L + 28. It is twice as steep as labor demand and has the same vertical intercept.
b.
Equate LS to LD. Then we have
50W - 100 = 700 - 25W
W = 10.67
Plug W into labor supply or labor demand to get L = 433. (Since either the supply equation or the demand equation may be used here, students' answers will differ slightly due to rounding.)
c.
Find the value of L where MR = 0. This occurs at L = 350. Plugging this into the demand equation, we obtain W = $14.

Assume that there is a shortage of lobster and that for whatever reason prices have not risen to choke off the excess demand
Instead, the government has exhorted people to voluntary refrain from lobster consumption to "maintain a balance between supply and demand." Assume that the temporary public service announcements are "effective" and the public reduces its consumption of lobster. Explain using supply and demand analysis what should happen to the equilibrium quantity of lobster and its equilibrium price. Why would this plan not have much of an impact on the lobster market in the long run?
