Possíveis Impactos do Quantitative Easing (QE2) Sobre a Economia Americana
Martin Feldstein com a palavra:
"At the annual Fed conference at Jackson Hole, Wyoming in August, Fed Chairman Ben Bernanke explained that he was considering a new round of quantitative easing (dubbed QE2), in which the Fed would buy a substantial volume of long-term Treasury bonds, thereby inducing bondholders to shift their wealth into equities. The resulting rise in equity prices would increase household wealth, providing a boost to consumer spending.
To be sure, there is no proof that QE2 led to the stock-market rise, or that the stock-market rise caused the increase in consumer spending. But the timing of the stock-market rise, and the lack of any other reason for a sharp rise in consumer spending, makes that chain of events look very plausible.
The magnitude of the relationship between the stock-market rise and the jump in consumer spending also fits the data. Since share ownership (including mutual funds) of American households totals approximately $17 trillion, a 15% rise in share prices increased household wealth by about $2.5 trillion. The past relationship between wealth and consumer spending implies that each $100 of additional wealth raises consumer spending by about four dollars, so $2.5 trillion of additional wealth would raise consumer spending by roughly $100 billion.
That figure matches closely the fall in household saving and the resulting increase in consumer spending. Since US households’ after-tax income totals $11.4 trillion, a one-percentage-point fall in the saving rate means a decline of saving and a corresponding rise in consumer spending of $114 billion – very close to the rise in consumer spending implied by the increased wealth that resulted from the gain in share prices.
None of this appears to augur well for 2011. There is no reason to expect the stock market to keep rising at the rapid pace of 2010. Quantitative easing is scheduled to end in June 2011, and the Fed is not expected to continue its massive purchases of Treasury bonds after that."
