Does monetary policy really face a zero lower bound or could policy rates be pushed materially below zero per cent? And would the benefits of reforms to achieve negative policy rates outweigh the costs? This column, which reports the views of the leading UK-based macroeconomists, suggests that there is no strong support for reforming the monetary system to allow policy rates to be set at negative levels.

Claims that ‘austerity has failed’ are popular, especially in the Anglo-Saxon world. This column argues that this narrative is factually wrong and ignores the reasons underlying the Greek crisis. The worst move for Greece would be to return to its old ways. Greece needs to realise that things could actually become much worse than they are now, particularly if membership in the Eurozone cannot be assured. Instead of looking back, Greece needs to continue building a functioning state and a functioning market economy.

The conventional ‘trilemma’ view is that countries that allow free capital flows can still pursue independent monetary policies as long as they allow flexible exchange rates. This column examines the pass-through of Federal Reserve interest rates to policy rates in Chile, Colombia, and Mexico. The author concludes that, to the extent that central banks take into account other central banks’ policies, there will be ‘policy contagion’ and that, even under flexible rates, monetary policy will not be fully independent.

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.

Expectations are critical for macroeconomics and financial markets. But the expectation-formation process is not well understood. This column discusses some empirical characteristics of forecast disagreement from professional forecasters in the US, and discusses the ‘information frictions’ that underlie the heterogeneity of expectations.

Eurozone inflation has been persistently declining for almost a year, and constantly undershooting forecasts. Building on existing research, this column explores the conjecture that low inflation in the Eurozone results from an excess demand for safe assets. If true, this conjecture would have definite policy implications. Getting out of such a ‘safety trap’ would necessitate fiscal or non-conventional monetary policies tailored to temporarily take risk away from private balance sheets.

The post-Crisis G7 economies have suffered weak business investment despite record low interest rates and the favourable financial positions of corporates. Some consider this the ‘new normal’ arising from secular, supply-side forces that have contributed to declining potential growth rates. This column argues that structural factors alone are not sufficient to explain the current weakness in investment rates. There is thus room for positive surprise if companies realise the pent-up investment demand.

The share of compensation to labour in gross value added has declined in recent decades for most countries and industries around the world. Recent work has also used the share of compensation to labour in net value added as a proxy for inequality. This column discusses that gross and net labour shares have declined together for most countries since 1975 – an outcome consistent with the worldwide decline in the relative price of investment goods.

Most of the world is now at the point where the support ratio is becoming adverse, and the growth of the global workforce is slowing. This column argues that these changes will have profound and negative effects on economic growth. This implies that negative real interest rates are not the new normal, but rather an extreme artefact of a series of trends, several of which are coming to an end. By 2025, real interest rates should have returned to their historical equilibrium value of around 2.5–3%.

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.

Many central banks embrace forward guidance by announcing expected interest rate paths. But how likely it is that actual rates will be close to expected ones? This column argues that quantifying such uncertainty poses great difficulties. Precise probability statements in a world of uncertainty (not just risk) can be misleading. It might be better to rely on qualitative guidance such as: “Interest rate rises will probably be gradual and likely to be to a level below the old normal”.

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.

Real interest rates have fallen to historic lows, and some economists are concerned that an era of secular stagnation has begun. This column highlights the role of policy frameworks and financial factors – particularly debt – in linking low real interest rates and sluggish economic growth. Policies that do not lean against booms but ease aggressively and persistently in busts induce a downward bias in interest rates over time and an upward bias in debt levels – something akin to a debt trap. Low real interest rates may thus be self-reinforcing and not always ‘natural’.

In the aftermath of the LIBOR scandal, it is important to re-establish a credible reference rate for the pricing of financial instruments and of wholesale and retail loans. The new candidate must meet the five criteria suggested by the Bank for International Settlements – reliability, robustness, frequency, availability, and representativeness – in all circumstances. This column argues that strengthening governance and/or adopting a trade-weighted reference rate is probably the fastest approach, but not necessarily sufficient for a resilient reference rate in the long run.

The ‘neutral’ rate is the real interest that is consistent with stable inflation and narrow output gaps. This column discusses the various estimation techniques and presents estimates for a range of Latin American nations. No methodology is fully correct: central banks must still make a subjective judgement, but econometrics can significantly help to inform it.

The Eurozone is moving towards a banking union with the ECB at its centre. This column argues that there are problems with the European Commission’s proposal. The ECB can never supervise all 6000 banks in the Eurozone, supervision should be separated from monetary policy to avoid conflicts of interest, and joint deposit insurance and resolution funds must be created. Furthermore, the ECB should exert constructive ambiguity in its supervision.

Do low interest rates encourage excessive risk-taking by banks? This column summarises two studies analysing the impact of short-term interest rates on the risk composition of the supply of credit. They find that lower rates spur greater risk-taking by lower-capitalised banks and greater liquidity risk exposure.
