The national accounts identity tells us that saving equals investment, or S = I. In the Keynesian cross model, we assumed that desired investment is fixed. This implies that investment is the same in the new equilibrium as it was in the old. We can conclude that saving is exactly the same in both equilibria. C. Why do you suppose this result is called "the paradox of thrift"?
