As shown in Figure 4A an upward shift in XS results in a higher equilibrium credit spread, and a lower volume of lending, for any given level of economic activity (reflected in the location of the XD schedule in the figure). Transferring this larger spread back to Figure 3A, one observes that the implied value of i s will be smaller, and the implied value of i b higher, for the given value of Y. Because this is true for each possible value of Y, the IS schedule is shifted down Because the and to the left, as shown in Figure 4B. (Note that IS plots the equilibrium value of because i s rather than that of i b, because the policy reaction function specifies a target for s b i rather than for i .) In the absence of any change in the monetary policy reaction .) 8 Of course, these reasons for the IS cur...
