Recent experience with the zero lower bound on nominal interest rates, and the use of high-denomination notes by criminals and tax evaders, have led to revived proposals to phase out cash. This column argues that abolishing cash may be neither necessary nor sufficient to overcome the zero lower bound problem, and would severely undermine privacy. Allowing the public to hold reserves at central banks could reduce the need for deposit insurance, although the transition to the new regime and the effects on credit supply must be carefully considered.

Macroecomics has changed in a number of ways since the global crisis. For example, there is now more emphasis on modeling the financial sector, self-fulfilling panics, herd behaviour and the new role of demand. This Vox Talk discusses these changes as well as those areas in macroeconomics that are currently perhaps not researched enough. Wouter den Haan explains the inadequacy of the conventional 'rational expectations' approach, quantitative easing, endogenous risk and deleveraging and refers to current CEPR research that reflects the changes. He concludes by reminding us that the 'baby boomers' issue could be the basis of the next crisis.

Today’s Eurozone fiscal discipline is the amalgamation of reforms implemented over ten years, with the latest and largest changes agreed in crisis settings. This column argues that the result fosters neither growth nor stability since actual fiscal policy has been powerfully procyclical. The focus on intermediate targets has distracted attention from the final objectives – debt sustainability and economic convergence. A drastic simplification of the current rules is proposed.

A triple-dip recession in the Eurozone is now a distinct possibility. This column argues that additional monetary stimulus is unlikely to be effective, that the scope for further fiscal stimulus is limited, and that some structural reforms may actually hurt growth in the short run by adding to disinflationary pressures in a liquidity trap. The author advocates using tax incentives and tighter regulations to encourage firms to replace environmentally inefficient capital.

There has been a long-term downward trend in labour’s share of national income, depressing both demand and inflation, and thus prompting ever more expansionary monetary policies. This column argues that, while understandable in a short-term business cycle context, this has exacerbated longer-term trends, increasing inequality and financial distortions. Perhaps the most fundamental problem has been over-reliance on debt finance. The authors propose policies to raise the share of equity finance in housing markets; such reforms could be extended to other sectors of the economy.

The impact of the stock and maturity of government debt on longer-term bond yields matters for monetary policy. This column assesses the magnitude and relative importance of overall bond supply and maturity effects on longer-term US Treasury interest rates using data from 1976 to 2008. Both factors have a significant impact on both forwards and term premia, but maturity of public debt appears to matter more. The results have implications for exit from unconventional policies, and also for the links between monetary and fiscal policy and debt management.

World War I profoundly altered the structure of the US economy and its role in the world economy. However, this column argues that the US learnt the wrong lessons from the war, partly because a halo of victory surrounded wartime policies and personalities. The methods used for dealing with shortages during the war were simply inappropriate for dealing with the Great Depression, and American isolationism in the 1930s had devastating consequences for world peace.

Olivier Blanchard, Friday, October 3, 2014

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.

Roberto Perotti, Saturday, September 13, 2014

There is a growing consensus that austerity is contributing to the Eurozone’s macroeconomic malaise, but also that spending cuts are needed in the long run to achieve fiscal sustainability. Some commentators have advocated a temporary tax cut financed by unsterilised ECB purchases of long-term public debt, accompanied by a commitment to future spending cuts. This column argues that such commitments are simply not credible – especially given the moral hazard problem created by central bank monetisation of debts.

‘Cash for Clunkers’ was billed as a stimulus programme that would boost sales to the ailing US auto industry in 2009. This column shows that the design of the programme actually caused it to reduce revenues to the industry it was designed to help. The authors estimate that the entire increase in sales during the programme would have happened anyway in the following eight months. Moreover, since more fuel-efficient cars tend to be less expensive, the fuel economy requirement of the programme incentivised households to buy cheaper cars.

The stagnating Eurozone economy requires policy action. This column argues that EZ leaders should agree a coordinated 5% tax cut, extension of budget deficit targets by 3 or 4 years, and issuance of long-term public debt to be purchased by the ECB without sterilisation.

The discussion on pension reform typically centres on fiscal sustainability. This column argues that equity concerns are of primary importance, both in selling proposed reforms to the public, and as a first-order policy goal of the pension system. Focusing on the average pensioner is insufficient to evaluate policy.

There has been a stark contrast between the experiences of Spain and the UK since the Global Crisis. This column argues that although the ECB’s Outright Monetary Transactions policy has been instrumental in reducing Spanish government bond yields, it has not made the Spanish fiscal position sustainable. Although the UK has implemented less austerity than Spain since the start of the crisis, a large currency depreciation has helped to reduce its debt-to-GDP ratio

The question of whether fiscal policy should be pro- or countercyclical has become increasingly relevant during the recession. This column provides causal evidence from South American countries showing the success of countercyclical policy in improving social indicators of economic success, combined with correlative evidence from Europe. This represents a strike against the case for austerity-led growth.

The causes and consequences of rising inequality have stirred a lively debate on appropriate policy responses. This column reviews how governments have successfully used fiscal policy to address distributive concerns. It also examines the policy alternatives that countries can pursue in order to reduce income and wealth inequality at a minimum cost to efficiency. Such policies include exploitation of property taxes, reductions in tax deductions that favour upper-income groups, investing in increasing the human capital of low-income groups, and reforming social benefits.

The recent debate on the link between austerity and growth has focused on the short run. This column discusses recent research into the link between fiscal consolidation and medium-term growth under different financial conditions. If credit is not available to consumers and investors, private demand is less able to compensate for cutbacks in public demand, so large spending cuts can have a negative effect on growth. Difficult financial conditions probably explain why fiscal adjustments that worked in the 1990s have not produced similar beneficial effects on growth in recent years.

Although progress has been made on resolving the Eurozone crisis – vulnerable countries have reduced their current-account deficits and implemented some reforms – more still needs to be done. This column argues for a ‘consistent trinity’ of policies: structural reforms within countries, more symmetric macroeconomic adjustment across countries, and a banking union for the Eurozone.

Daniel Gros, Wednesday, March 19, 2014

Since the onset of the sovereign debt crisis, the argument for a system of fiscal transfers to offset idiosyncratic shocks in the Eurozone has gained adherents. This column argues that what the Eurozone really needs is not a system which offsets all shocks by some small fraction, but a system which protects against shocks which are rare, but potentially catastrophic. A system of fiscal insurance with a fixed deductible would therefore be preferable to a fiscal shock absorber that offsets a certain percentage of all fiscal shocks.

Willem Buiter, Friday, January 10, 2014

Fiscal sustainability has become a hot topic as a result of the European sovereign debt crisis, but it matters in normal times, too. This column argues that financial sector reforms are essential to ensure fiscal sustainability in the future. Although emerging market reforms undertaken in the aftermath of the financial crises of the 1990s were beneficial, complacency is not warranted. In the US, political gridlock must be overcome to reform entitlements and the tax system. In the Eurozone, creating a sovereign debt restructuring mechanism should be a priority.

Hans Gersbach, Saturday, January 4, 2014

Democratic governments tend to accumulate excessive debt. This column proposes a new rule – the ‘Catenarian Fiscal Discipline’ – which allows a fiscally disciplined incumbent to limit the debt-making of the next officeholder. This way, fiscal discipline today can lead to fiscal discipline in the future. Such a rule would require that we broaden our notion of representative democracy by recognising the fact that a current government already has various implicit ways of limiting what its elected successors can do.
