Consider two countries: Albania, relatively abundant in low-skill labour, and Switzerland, relatively abundant in high-skill labour. Assume high- and low-skill labour are the only factors used in the production of the only two existing goods, and that neither type of labour are allowed to move across countries. Suppose that, initially, Albania is closed to trade. If later Albania joins the EU and hence the free trade agreement (FTA) with Switzerland (with no labour mobility), then: a. low-skill workers would benefit from this only in Switzerland and lose in Albania b. low-skill workers would benefit from this in both countries c. high-skill workers would benefit from this in both countries d. high-skill workers would benefit from this only in Switzerland and lose in Albania.
