Consider a world with two countries - USA and Foreign and a competitive market of sugar in both countries. Foreign is more effecient in the production of sugar and in a free trade equilibrium, US would import part of its consumption of sugar. Describe graphically such trading equilibrium of sugar. What would be the effect on the sugar price in USA and on the welfare (measured by consumer surplus, pro- ducer surplus and tari§ revenue) of US when US imposes an import tariffs on sugar? Argue using a graph taking into consideration that US is a large sugar importing country.

Korea’s demand for computers isQK = 2, 000 − PkIts supply isQK = −200 + PkChina’s demand for computers isQC = 1, 000 − Pc Its supply isQC = Pc1. Suppose that Korea imposes a specific tariff of $100 on computerimports. Calculate the price of computers in each country and thequantity of computers supplied and demanded in each country. Alsocalculate the volume of trade.

The following graph shows the domestic supply of and demand for soybeans in Guatemala. The world price (Pw) of soybeans is $540 per ton and is represented by the horizontal black line. Throughout the question, assume that the amount demanded by any one country does not affect the world price of soybeans and that there are no transportation or transaction costs associated with international trade in soybeans. Also, assume that domestic suppliers will satisfy domestic demand as much as possible before any exporting or importing takes place.
