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.
