Labour shares, inequality, and the relative price of capital
Loukas Karabarbounis, Brent Neiman 25 November 2014
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.
At least since Kaldor (1961), the constancy of the labour share of income has been considered one of the key foundations underlying macroeconomic models. In Karabarbounis and Neiman (2014a), we documented a global decline in the share of labour compensation in gross income (‘gross labour share’) since 1975 and emphasised the role of declining investment prices for this trend. Piketty (2014) and Piketty and Zucman (2014) also discussed this factor share movement and linked it to increases in the capital–output ratio.

Demography and economics: Look past the past
Charles A.E. Goodhart, Philipp Erfurth 04 November 2014
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%.
Our history is our database. When seeking to peer dimly into the future, our normal response is to examine what happened in (similar) past episodes and then to extrapolate those outcomes into the future. This assumption, that the future will mimic the past, is hard-wired into almost all our forecasting exercises, from the most simple to the econometrically and technically most complex.

Monetary policy and long-term trends
Charles A.E. Goodhart, Philipp Erfurth 03 November 2014
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.
There has been a long-term downward trend in the share and strength of labour in national income, which is depressing both demand and inflation. This has prompted ever more expansionary monetary policies. While understandable, indeed appropriate, within 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 (leverage).

The impact of the maturity of US government debt on forward rates and the term premium: New results from old data
Jagjit Chadha 02 November 2014
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.

The question of the impact of the stock and maturity of net government debt on longer-term US Treasury yields, and the potential implications for central bank balance sheet policies, matters for monetary policy.

“Mensch tracht, und Gott lacht” – what’s the best guidance on monetary policy?
David Miles 22 October 2014
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”.
“Mensch tracht, und Gott lacht” is a Yiddish proverb – men plan and God laughs. Woody Allen puts the same thought this way: “If you want to make God laugh tell him about your plans”. Some people might see these words as a fitting epitaph for forward guidance on monetary policy. The Bank of England has certainly faced a good deal of criticism for the guidance that it has recently been giving, as has the Federal Reserve in the US.

Quantifying the macroeconomic effects of large-scale asset purchases
Karl Walentin 11 September 2014
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.
Central banks have used various unconventional monetary policy tools since the onset of the financial crisis yet the debate continues regarding their efficiency. This column attempts to shed light on the ‘bang for the buck’, or the macroeconomic effects, of one such unconventional monetary policy – the Federal Reserve’s large-scale asset purchases of mortgage-backed securities employed during the Fed’s QE1 and QE3 programs.

The role of corporate saving in global rebalancing
Philippe Bacchetta, Kenza Benhima 24 August 2014
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 increase in global imbalances in the last decade posed a theoretical challenge for international macroeconomics. Why did some less-developed countries with a higher need for capital, like China, lend to richer countries? The inconsistency of standard open-economy dynamic models with actual global capital flows had already been stressed before (e.g. by Lucas 1990), but the sensitivity to this issue became more acute with increasing global imbalances. This stimulated the development of several alternative theoretical frameworks.

Secular stagnation: Facts, causes, and cures – a new Vox eBook
Coen Teulings, Richard Baldwin 10 September 2014
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.
Teaser from original column posted on 15 August 2014
Six years after the Crisis and the recovery is still anaemic despite years of zero interest rates. Is ‘secular stagnation’ to blame? This column introduces an eBook that gathers the views of leading economists including Summers, Krugman, Gordon, Blanchard, Koo, Eichengreen, Caballero, Glaeser, and a dozen others. It is too early to tell whether secular stagnation is really secular, but if it is, current policy tools will be obsolete. Policymakers should start thinking about potential solutions.

Low interest rates and secular stagnation: Is debt a missing link?
Claudio Borio, Piti Disyatat 25 June 2014
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’.
Today, the US government can borrow for ten years at a fixed rate of around 2.5%. Adjusted for expected inflation, this translates into a real borrowing cost of under 0.5%. A year ago, real rates were actually negative. With low interest rates dominating the developed world, many worry that an era of secular stagnation has begun (Summers 2013).

The LIBOR scandal: What’s next ? A possible way forward
Vincent Brousseau, Alexandre Chailloux, Alain Durré 09 December 2013
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.
After the first allegations of LIBOR manipulation in May 2012 – which eventually resulted in investigations into banks and individuals in various countries as of June 2012 – the reliability and credibility of unsecured reference rates in various currencies (the LIBOR in pounds, dollars, euros, and yen, and also the EURIBOR) have been severely questioned. With a view to restoring the credibility of these important reference interest rates, financial regulators have launched a broad consultation to study possible options to avoid similar manipulation in the future.
