Central bankers are once again talking about the possible need for more quantitative easing to ease the aggregate spending losses associated with ongoing fiscal austerity programs in some countries. If calibrated correctly, QE can replace the net financial assets destroyed by the austerity.
Answer: False
The answer is False.
Quantitative easing then involves the central bank buying assets from the private sector - government bonds and high quality corporate debt. So what the central bank is doing is swapping financial assets with the banks - they sell their financial assets and receive back in return extra reserves. So the central bank is buying one type of financial asset (private holdings of bonds, company paper) and exchanging it for another (reserve balances at the central bank). The net financial assets in the private sector are in fact unchanged although the portfolio composition of those assets is altered (maturity substitution) which changes yields and returns.
In terms of changing portfolio compositions, quantitative easing increases central bank demand for "long maturity" assets held in the private sector which reduces interest rates at the longer end of the yield curve. These are traditionally thought of as the investment rates. This might increase aggregate demand given the cost of investment funds is likely to drop. But on the other hand, the lower rates reduce the interest-income of savers who will reduce consumption (demand) accordingly.
How these opposing effects balance out is unclear but the evidence suggests there is not very much impact at all.
You should read the answer to Question 3 to reflect on how fiscal policy adds net financial assets to the non-government sector by way of contradistinction to QE.
