The
The equilibrium credit spread and volume of credit shown in Figure 3A are
determined for a particular value of national income Y ; because the schedules LS
and LD depend on Y, as shown in Figure 2A, the location of the schedule XD (at

level of Y should shift LS to the right and LD to the left, and each of these effects
results in a lower equilibrium value of the rate i s paid to savers, for any given position
of the schedule XS. Hence we can once again derive an IS schedule, indicating the
