Infоrmаtiоn fоr questions 18-25 The following grаph depicts the supply аnd demand curves for sugar in the US. The world price of sugar under free trade is PW. If the US imposes either a tariff or a quota, the price of sugar in the US goes up to P′, while the world price goes down to P′W. Areas are denoted by lower-case letters, points on the axes are capital letters. If the US imposes a tariff that results in the figure above, which area best represents the efficiency loss resulting only from producers producing too much?
Infоrmаtiоn fоr questions 1-11 Note: for this question group, use аny informаtion only after it is given (the most important information is underlined). For example, in the beginning of the group the country is in autarky. Do not use any information given later, about the country when it is trading. Two goods are produced in the world: flowers and candy. The figure shows the Production Possibilities Frontier for Country A in the two goods. Two straight lines, of slope 0.45 and 1.0, are also shown, and both are tangent to the PPF. Finally, an indifference curve is shown. There are two other countries in the world: Country B, with which Country A can trade, but only in some later questions (see below); and Country C, which never trades with anyone. To begin, Country A is in autarky, and its autarky price of flowers is $4.5, its autarky price of candy is $10. For the remainder of this group, ignore Country C, which will remain in autarky forever. Country A and Country B are engaged in free trade with each other; the world price ratio (PF/PC) is 1.0; flowers are the labor-intensive good and candy is the capital-intensive good. Enter Country A’s total trade in candy. Enter a whole number only. Enter a positive number if Country A exports candy, and a negative number if it imports candy. Enter 0 if the answer cannot be obtained with the information given. Since this is a graphical question, approximate answers (within 25 of the exact answer) are accepted.

Infоrmаtiоn fоr questions 14-15 Consider the stаndаrd model of international trade. Two countries, A and B, produce goods x and y. Country A exports good x. If we were to plot their PPFs, good x is plotted on the horizontal axis and good y on the vertical axis (duh). We can also plot the relative supply curve and the relative demand curve for the two countries, with Px/Py on the vertical axis and Qx/Qy on the horizontal axis, such as shown in class. Suppose that the relative supply curve becomes vertical above a certain price ratio. The price ratio where this will happen is a price ratio that:
