American students have organized opposition to the sale by their campus stores of university apparel made for American retailers by workers in foreign countries who work in sweatshop conditions (long hours at low pay in bad working conditions).

Assume this movement takes the form of boycotting items made under sweatshop conditions.

a. Analyze the immediate labor market outcomes for sweatshop workers in these countries using supply and demand curves to illustrate the mechanisms driving the outcomes.

b. Assuming that actions by American students are the only force driving the improvement of wages and working conditions in foreign countries, what must these actions include to ensure that the workers they are seeking to help are unambiguously better off?
