1. Draw a diagram with the same two countries and with the same production possibilities and exchange ratio as in Figure 24.5. But this time show how much would be imported and exported for each country if, after trade, the LDC consumes 500 million kilos of wheat. Fill the figures in on a table like Table 24.5.
\r\n2. If the opportunity cost ratio of wheat for cloth is 1/2 in the LDC, why is the slope of the production possibility curve 2/1? Is the slope of the production possibility curve always the reciprocal of the opportunity cost ratio?
\r\n3. Show (graphically) that, if the (pre-trade) opportunity cost ratios of the two countries were the same, there would be no gain from trade – assuming that the production possibility curves were straight lines and did not shift as a result of trade.
