Conventional economic theory predicts that, outside of a financial crisis, quantitative easing should have no effect on real outcomes or inflation. This column proposes two theoretical channels through which quantitative easing might also work in a fiscal crisis. In this case, quantitative easing can be a valuable tool because it can control the path of inflation over time and reduce the distortions to the credit flow in the economy.

The rising share of income accruing to housing is a key feature of the changing US income distribution. This column examines the determinants of this phenomenon. The rise occurred due to an increasing share of income accruing to owner-occupiers through imputed rent, it is concentrated in states that are constrained in terms of new housing supply, and it is closely associated with the long-run decline in real interest rates and inflation.

Models that estimate optimal inflation rates struggle to accurately account for interest rates reaching the zero lower bound, due to the lack of historical data available. This column suggests periods of hitting the zero lower bound are longer than previously thought, and models the optimal inflation rate target on this. Given the uncertainty associated with measuring the historical frequency and duration of such episodes, the wide range of plausible optimal inflation rates implies that any inflation targets should be treated with caution.

Policymakers use forecasting to attempt to assess the impact of major events, such as the recent Brexit vote, on the economy. While forecasting has improved dramatically in recent years, the models can still be greatly improved. This column discusses some of the limitations of forecasting models, and how policymakers can make their predictions more reliable. Key considerations are using more data to generate predictions, and using myriad models to eliminate individual misspecifications.

Low inflation targets can cause economies to hit the zero lower bound during deflationary periods caused by even mild shocks. In such circumstances, central banks lose their ability to stimulate the economy. This column assesses the risk of this happening using a model that endogenises self-perpetuating optimism and pessimism in the economy. Given agents’ intrinsic chronic pessimism during times of recession, central banks should raise their inflation targets to 3 or 4% to preserve their ability to stimulate the economy when needed.

Big Data is changing the world, even economics. This column describes MIT’s Billion Prices Project and discusses key lessons for both inflation measurement and some fundamental research questions in macro and international economics. Online prices can be used to construct daily price indexes in multiple countries and to help avoid measurement biases.

Many claim that monetary policy has hit diminishing returns. They use that as an explanation for the slower economic growth and low inflation in the Eurozone. This column argues that the main problem is that the ECB acted late and with half-measures to the Global Crisis, which was seen as falling short of its promises. The real problem is thus not a lack of ammunition, but a lack of credibility.

Central banks are there to ensure price stability, and economists generally agree that politics and central banking don’t mix well. This column takes us through the inflationary and more controlled history of Israel’s central bank, highlighting the current policy dilemmas facing the country.

The quantity theory of money implies that sustained inflation requires a sustained increase in the money supply. It does not, however, imply that the reverse is also true. This column explores and illustrates this issue by comparing inflation in the US following the collapse of Lehman Brothers with Germany’s hyperinflation experience after WWI. A key factor explaining the vastly different inflation experiences is how the monetary expansion translated into demand. The Fed’s base expansion did not translate into demand for goods and services, whereas the German monetary expansion was motivated by the government’s hunger for seigniorage revenues.

The ECB’s response to the Crisis – not providing stimulus to the Eurozone economy when it needed it, and allowing it to slip into a low inflation trap – is a reflection of the monetary union’s faulty architecture. This column recalls a 1998 manifesto from several distinguished scholars that warned EZ policymakers of the potential consequences of a misguided policy framework. Two sets of issues need to be critically addressed by current EZ policymakers: its objectives and instruments.

One thing economists can agree on is that inflation is hard to forecast. This column argues that in this context, the idea that ‘core inflation’ may be a useful predictor is very appealing, especially for central banks that need to know where inflation is heading. Evaluating the ability of core to forecast headline inflation for OECD and some non-OECD countries, it seems that sizable predictability emerges for a very small subset of countries, but it is either subtle or undetectable for most other economies.

Today's monetary policy effectiveness depends on expectations of future monetary policy. Shocks affect such expectations, but the nature of the shock matters. This column presents evidence that negative demand shocks lead markets to expect looser policy in the short run. Negative supply shocks lead to expectations of looser policy in the medium to long run. Unexpected expansions – from either the supply or demand side – have no significant influence on markets' expectations of future monetary policy.

Central banks around the world have been shouldering ever-increasing policy burdens beyond their core mandate of stabilising prices. This column considers the social welfare implications when central banks take on additional mandates that are usually the domain of other policymakers. Additional mandates are shown to worsen trade-offs faced by the central bank, while distorting the incentives of other policymakers. Central bank ‘mandate creep’ may be detrimental to welfare.

There is generally consensus among macroeconomists that monetary policy works best when it is systematic. Following the financial crisis, the US Federal Reserve shifted from long-term, systematic policy to short-term goals targeting unemployment. This column argues that, while these were appropriate in the aftermath of the downturn, such policy accommodations have been pursued for too long since. The need for a somewhat accommodative policy cannot be used to defend the current non-systematic policy and excessive emphasis on short-term employment gains.

From the introduction of the euro in 1999 to the Greek crisis in 2010, the Eurozone witnessed external imbalances between countries at its core and those at its periphery. These imbalances have been attributed either to differences in competitiveness or to the effect of financial integration. This column argues that in order to understand the imbalances within the Eurozone, it is necessary to consider credit costs and capital flows. The lower real cost of credit for high-inflation countries must be taken into account, as well as the inflow of capital to the non-tradable sector that this implies. Monetary policy cannot be conducted in a ‘one size fits all’ manner.

EZ inflation has been falling steadily since early 2013, turning negative in late 2014. This column surveys a host of recent research from Banca d’Italia that examined the drivers of this fall, its macroeconomic effects, and ECB responses. Aggregate demand and oil prices played key roles in the drop, which has consistently ‘surprised’ market-based expectations. Towards the end of 2014 the risk of the ECB de-anchoring inflation expectations from the definition of price stability became material.

Despite being a mainstay of macroeconomic theory for the past half century, the Phillips curve often receives the death knell from various commentators. These critiques often rely on results from data samples spanning relatively short periods. Using the case of Ireland, this column argues that short-term idiosyncrasies can explain the failure of the model in these contexts. Taking a longer historical view, the Phillips curve remains a useful macroeconomic model, at least in the Irish context.

Financial dollarisation, the widespread holding of assets and liabilities in a foreign currency, is often viewed as a threat to financial stability in emerging markets. However, there is not enough evidence that monetary policy is responsible for low dollarisation. This column uses cross-regional evidence from Russia to show that monetary stability is indeed a key determinant of dollarisation. Moreover, banking integration strongly influences how households and firms adjust the currency composition of their assets and liabilities to changes in monetary conditions.

Following the Warsh Review, the recording, number, and timing of the Bank of England’s Monetary Policy Committee meetings will change. This column argues that the recording may make the decision meeting more formal and could inhibit debate, although the eight-year gap before publishing transcripts ameliorates this concern. Having fewer MPC meetings is a good thing, and reduces ‘noise’ around monetary policy. The revised meeting schedule will not add to transparency and raises the risk of leaks and ‘news shocks’.
