Figure 3-21 Uzbekistan's Production Possibilities Frontier Azerbaijan's Production Possibilities Frontier A pair of linear production possibilities frontier curves of nails versus bolts for two countries, Uzbekistan and Azerbaijan. Uzbekistans linear production possibilities frontier curve for nails versus bolts is a straight line that connects point (0, 60) to point (30, 0).Azerbaijans linear production possibilities frontier curve for nails versus bolts is a straight line that connects point (0, 80) to point (20, 0). Refer to Figure 3-21.
