a) unlike music streaming companies, have to abide by government sanitation rules.
b) unlike music streaming companies, do not have significant economies of scale.

3) A patent

b) gives a firm the exclusive right to a new product for 20 years from the date the patent application is filed with the government.

4) A CBO study estimated that the excess burden from the corporate income tax ________ of the revenues raised by the tax. This estimate would make the corporate income tax ________ imposed by the federal government.

5) A number of economists have estimated the impact of unionization on workers’ wages. Which of the following is one conclusion reached by these studies?
a) Being in a union increases a worker’s wages by about 10 percent, holding constant other factors that influence wages.
b) Union workers earn less than they would if they were not unionized. This is because of the impact of workers’ strikes, during which union members do not receive wages.
c) Holding constant the impact of other factors that affect wages, being in a union has no impact on a worker’s wages.
d) The share of national income received by workers has increased significantly over time; unions have been responsible for about one-half of the increase in workers’ share of national income from the end of World War II to 2000.
