A) For the UK, what is opportunity cost of cheese and wine? What about for the Rest of the World (again, cost of cheese and wine)? B) Which country has the comparative advantage in Cheese? Wine? Given this, how much of each good does the UK choose to produce (given their labor supply)?

The countries of Sanaton and Microtania each produce two goods: Airplanes and Computers. The table below lists the opportunity costs associated with producing each good, for each country. Country Opportunity cost of producing 1 Airplanes Opportunity cost of producing 1 Computers Sanaton 4 Computers 0.25 Airplanes 2 Airplanes Microtania 0.5 Computers Currently, Sanaton does not trade with Microtania, and on its own produces 19 Airplanes and 24 Computers. On their own, Microtania produces 30 Airplanes and 35 Computers. Calculate total world supply: Airplanes: → Computers: If Sanaton decided to change its production of Airplanes by -2, calculate the change in the production of Computers: If Microtania changed its production of Airplanes by 8, calculate the change in production of Computers: A

There are two countries Home and Foreign. Home has 1,200 units of labor available. It can produce two goods, apples and bananas. The unit labor requirement in apple production is 3, while in banana production it is 2. Foreign has a labor force of 800. Foreign's unit labor requirement in apple production is 5, while in banana production it is 1. Suppose world relative demand takes the following form: Demand for apples/demand for bananas = price of bananas/price of apples a-b. On the graph to the right: 1.) Using the 3-point curved line drawing tool, draw the relative demand curve. Label the curve RD. 2) Using the point drawing tool, indicate the equilibrium relative price of apples. Label this point EQ. Carefully follow the instructions above and only draw the required objects. 2 Relative price of apples Pa/Pb 0 035 0.75 05 Relative quantity of apples RS

Quantity of sugar 0 The figure above shows a country before and after the opening of trade. If coal is the labor-intensive good and sugar is the land-intensive good and this country is labor abundant: then [Select] is the autarky price, [Select] [Select] Quantity of coal î is the autarky consumption point, and ↑ is the consumption point after trade.
