FIGURE 8.11 The Keynesian Aggregate Supply Curve When the Money Wage us variable part a shows the equilibrium levels of employment N N Na, corresponding to successively higher values of the price level Po, Pi, Pr Part b gives the level of output yo, y that will be produced at each of these employment levels. Part c combines the information in parts a and b to show the relationship between the price level and output supplied. At higher values of the price level, output supplied increases; as in the fixed-wage case, the aggregate supply curve(y) is upward-sloping
