19 November 2015 Is Slower Growth the New Normal in Advanced Economies?This article reviews and examines some of the main explanations for the slow growth that many advanced economies continue to experience seven years after the 2007–09 global financial crisis. Does this muted recovery reflect just a prolonged cycle in the aftermath of a financial crisis? Is it due to a structural inadequacy of demand leading to a long-lasting liquidity trap? Or is it largely supply side in nature, reflecting demographic and technological factors?
This paper summarizes the international evidence on the performance of quantitative easing (QE) as a monetary policy tool when conventional policy rates are constrained by the effective lower bound (ELB). A large body of evidence suggests that expanding the central bank’s balance sheet through large-scale asset purchases can provide effective stimulus under the ELB.
The U.S. Federal Reserve responded to the great recession by reducing policy rates to the effective lower bound. In order to provide further monetary stimulus, they subsequently conducted large-scale asset purchases, quadrupling their balance sheet in the process.
