a) Using a demand/supply diagram, illustrate and explain the effects of the imposition of an export tax on a good Y by a home country’s government on (i) the home country’s consumers of Y, (ii) the home country’s producers of Y, and (iii) the home government’s tax revenues. (Assume that the country is a “small” country.) Then evaluate the “net welfare effect” of the tax on the country. Why might a country want to impose an export tax? Explain. (b) Suppose now that the country imposing the export tax in part (a) of this question is a “large” country rather than a “small” country. Is it an advantage or a disadvantage for a country to be “large” rather than “small” when it imposes an export tax? Explain. Note: Use diagrams where necessary to explain both (a) and (b).
