2.. Make a case for why monopolistically competitive

industries never reach long-run equilibrium

3.Are unions and technological improvements

complementary? Why or why not?

or why not?

5. If it is not profitable to discriminate, why does

discrimination persist?

in the past, should it be required to give priority to
