If taxpayers are not purely Ricardian, then private saving will rise by less than the fall in government saving. This response implies a decrease in the supply of national saving. The resulting excess demand for funds will put upward pressure on the domestic real interest rate. As the real interest rate increases, moreover, those components of aggregate demand that are sensitive to the interest rate-investment in particular-will fall. The result is what is called the crowding out of domestic investment; it is shown in Figure 32-7.
