In December 2008, the Fed lowered the federal funds rate to essentially zero and has kept it there since then. This column argues that, contrary to traditional macroeconomic thinking, monetary policy has not been severely constrained by the zero bound until mid-2011. The results imply that the Fed could have done more to ease monetary policy between 2009 and 2011. These findings could also help explain why the fiscal stimulus package adopted in 2009 did not bring the expected success.

Before the 2008 crisis, the mainstream worldview among US macroeconomists was that economic fluctuations were regular and essentially self-correcting. In this column, IMF chief economist Olivier Blanchard explains how this benign view of fluctuations took hold in the profession, and what lessons have been learned since the crisis. He argues that macroeconomic policy should aim to keep the economy away from ‘dark corners’, where it can malfunction badly.

Central banks have resorted to various unconventional monetary policy tools since the onset of the Global Crisis. This column focuses on the macroeconomic effects of the Federal Reserve’s large-scale purchases of mortgage-backed securities – in particular, through reducing the ‘mortgage spread’ between interest rates on mortgages and government bonds at a given maturity. Although large-scale asset purchases are found to have substantial macroeconomic effects, they may not necessarily be the best policy tool at the zero lower bound.

Among the various explanations behind global imbalances, the role of corporate saving has received relatively little attention. This column argues that corporate saving is quantitatively relevant, and proposes a theory that is consistent with the stylised facts and useful for understanding the current phase of global rebalancing. The theory implies that, while the economic contraction originating in developed countries has pushed interest rates towards the zero lower bound, the recent growth slowdown in emerging countries could push them out of it.

The CEPR Press eBook on secular stagnation has been viewed over 80,000 times since it was published on 15 August 2014. The PDF remains freely downloadable, but as the European debate on secular stagnation is moving into policy circles, we decided to also make it a Kindle book. This is available from Amazon; all proceeds will help defray VoxEU expenses.

Many central banks have recently employed unprecedented expansionary monetary policy, keeping interest rates at near-zero levels for an extended period of time. Quantitative easing interventions have been employed to affect asset prices directly, most notably in government-bond and mortgage markets, in order to keep sovereign and mortgage borrowing costs low. CEPR recently organised a conference to discuss existing theory and empirical evidence on the implications of an extended phase of unconventional monetary policy. This short column outlines the key issues and also includes a Vox Views video summary of the event.

Exiting from unconventional monetary policies is a key challenge facing policymakers in advanced nations and a key worry for everyone else. This column introduces the new 'Geneva Report' on the subject, Exit Strategies, by Alan Blinder, Thomas Jordan, Donald Kohn and Frederic Mishkin. The report considers what the post-exit world will look like, how we can get there and the long-run impact on central banking.

The authors of CEPR DP8642 offer a reminder about the usefulness of supply-side policies when the constraints of fiscal consolidation and the zero lower bound limit the macroeconomic-policymaking toolbox. A wealth effect from supply-side reforms could boost aggregate demand and help pull an economy out of the doldrums.

With nominal interest rates in many western countries at or approaching the zero lower bound, economists are calling for more quantitative easing or greater fiscal expansions to generate inflation, reduce real interest rates, and rejuvenate the economy. But what if these policies fail? Or are no longer possible? This column outlines a third way: supply-side policies.

Andrew Levin, 26 November 2010

Andrew Levin of the Federal Reserve talks to Romesh Vaitilingam about his research on optimal monetary policy at the zero lower bound. They discuss the effectiveness of forward guidance, the use of non-standard measures and the interactions between monetary and fiscal policy. The interview, which was recorded at the annual congress of the European Economic Association in Glasgow in August 2010, represents Andrew Levin’s personal views. [Also read the transcript]

CEPR Discussion Paper 8006 analyses how foreign demand shocks impact home economies when monetary policy is constrained by the zero lower bound. The authors find that even in relatively closed economies like the United States and the euro area, ZLB-constrained monetary policy amplifies the effects of foreign shocks.

How can monetary policy overcome the zero lower bound on interest rates? This column explores the possibility of negative nominal interest rates, arguing that, for it to work, all reserve nations must agree to protect against using foreign currencies as an alternative means of exchange.

Stefan Gerlach, John Lewis, 27 July 2010

Monetary policy during the global crisis entered unchartered territory. This column suggests that fear of a global recession may have led policymakers to cut rates more aggressively in order to prevent the need for negative interest rates.
