Figure 7-7 Figure 7-7   -Refer to Figure 7-7. Suppose the economy is initially in short-run equilibrium at point K. If the policy-makers adopt a nonintervention policy, over time,  I. real wages will fall as long as unemployment remains above the natural rate. II. lower nominal wages will result in a gradual shift from SRAS<sub>2</sub> to SRAS<sub>1</sub>. III. long-run equilibrium will be established at Y<sub>P</sub> and P<sub>h</sub>. -Refer to Figure 7-7. Suppose the economy is initially in short-run equilibrium at point K.
