Central banks have been called on to contribute to fighting climate change. This column presents a framework for thinking about the issue and identifies some major trade-offs and choices. It argues that climate should be a major part of risk assessments and that capital ratios could be used in a proactive way by applying favourable regimes to ‘green’ loans and investments. It also suggests that central banks may want to take several climate change-related aspects into account when designing and implementing monetary policies. However, the central bank should retain absolute discretion to interrupt any action if its first-priority objective – price stability – were to be compromised.

In December 2019, Marco Buti left the position of Director General for Economic and Financial Affairs at the European Commission at the end of a rough journey through the crisis and its aftermath. In this column, he draws the main lessons out of five key moments in the crisis for the completion of EMU and the appropriate policy mix in the euro area.

House prices and aggregate spending move together, but little is known about the underlying mechanism linking the two. This column introduces a test to discriminate between the housing wealth effect hypothesis, which says that homeowners consider home value changes as windfalls, and the collateral effect hypothesis, which says that a home value increase generates additional collateral that can be borrowed against. Homeowner behaviour in response to home value rises when they are close to their collateral borrowing constraint, suggesting that the collateral effect is important for explaining the link between house prices and spending. 


The Bank of Russia is hosting its third annual International Research Conference in Saint Petersburg on 7-8 July 2020 (Tuesday-Wednesday).

The scientific committee of the conference is comprised of the Research Advisory Board of the Bank of Russia.

Modern central banks perform multiple functions. They guarantee price and financial stability, carry out prudential regulation of financial sector trying to create the right stimulus for market players and enforce the rules of the game. A number of challenges appear regarding each of the policies as well as their interactions.

This conference will bring together researchers from academia, central banks, and policy institutions, who will present and discuss their theoretical and empirical research on challenges for these central banks’ policies and their interactions. The conference will also discuss rationale for changes to the ammunition of central banks to better address current and some future challenges.

If properly designed, even a small fiscal capacity can maximise its stabilisation effect. The column studies the macroeconomic stabilisation provided by the federal budget in the US as an example for monetary unions. Corporate income tax, on the revenue side, and social security, on the spending side, are the two most effective items. The key is to collect revenues based on the income of the most mobile factor, and to provide support to the income of the least mobile factor.

Research shows that individual spending behaviour is heterogeneous across households and that it depends on characteristics such as income and wealth. Using Italian data, this column shows that household heterogeneity plays a crucial role in the propagation of fiscal expenditure shocks. Household inequality gives rise to a rich set of new channels that propagate government expenditures shocks through consumer spending, which are related to households’ balance sheets and monetary-fiscal interactions. The values of the fiscal multiplier diverge from those predicted by the standard macroeconomic framework and the difference is particularly large at the zero lower bound.

Consumer goods prices systematically depend on product age. This column analyses this dependence and shows that relative prices tend to fall during the product lifecycle. It uses insights from a sticky price framework to demonstrate how these price trends matter for aggregate inflation and the optimal inflation rate

Preparations for reforming the euro area have stalled, with experts disappointed that politicians have not heard their proposals. This column, however, is optimistic  that the euro area can be reformed via a pragmatic reorientation without high-profile changes to the EU Treaty. The reforms must cover a reorientation of fiscal policy towards a long-term vision and entail revamping the Eurosystem to allow it to perform its proper role as a central bank.

Laurence Boone, Marco Buti, 18 October 2019

After years of solid growth, worldwide economic activity has slowed down sharply in 2019 while global trade has stalled. At October’s annual meeting of the IMF, policymakers have the difficult task of addressing the immediate policy challenges to support economic growth while also preparing our economies for the future. This column argues that while monetary policy is widely recognised as facing increasing constraints, fiscal policy and structural reforms need to play a stronger role. In particular, fiscal policy could become more supportive, notably in the euro area. Undertaking the right type of public investment now – in infrastructure, education or to mitigate climate change – would both stimulate our economies and contribute to making them stronger and more sustainable.

The newly released Euro Area Monetary Policy Event-Study Database makes available high-resolution data on asset price responses to ECB monetary policy announcements. In this column, the authors – the creators of the dataset – show that market perceptions of ECB policy communication comprise four factors: policy target, timing, forward guidance, and quantitative easing. These factors elicit large and long-lasting market reactions and help explain asset price changes in response to policy maker speeches and other news as well.

High frequency data are an essential input to study the effects of monetary policy communication. This column introduces a new database, the Euro Area Monetary Policy Event-Study Database, which makes available intraday asset price changes around ECB policy announcements for a wide range of assets. The high resolution of the intraday data allows for the measurement of asset price changes separately for the press release and press conference windows.

The decade since the Global Crisis has seen notable changes in the architecture of supervision, with separation of responsibility for monetary and financial stability having been reversed in many countries on the one hand, and a move towards more cross-border cooperation between supervisors on the other. This column discusses these two trends in Europe, where responsibility for supervision of the largest banks is housed in the same authority with responsibility for monetary policy, the ECB. It argues that the Single Supervisory Mechanism is a good reflection of the subtle economics of supervisory architecture and the many trade-offs that have to be taken into account.

Money market funds are important from a monetary policy perspective because they provide bank-like services and they are active in short-term funding markets. This column examines how recent extreme monetary policies have affected their performance and behaviour. Extreme monetary policy puts money market funds, which do not have access to the ECB’s deposit facility, under pressure by depressing the yields available on the assets they typically hold, leaving them at a competitive disadvantage relative to banks.  This could cause outflows of investment and unintended intermediation between banks and funds.

Japan’s monetary policy has had to be unconventional in order to address the economic conditions the country has faced. This column assesses the Bank of Japan’s exchange-traded fund purchasing programme, which has been repeatedly expanded in recent years. The purchases have achieved some positive results, propping up stock prices but also increasing real output and inflation. But, given the increased risks the Bank faces as its purchases have grown, the time to unwind has come.

The ECB's unconventional monetary policy package implemented in February 2012 changed collateral requirements. This column examines the effects in the French credit market, using data on corporate loans. Credit indeed increased after the liquidity injection, exclusively driven by supply. There was also strategic risk-taking by a group of banks, an unintentional implication of the policy.

Roger Farmer, Giovanni Nicolò, 20 May 2019

The economies of many countries are operating close to full capacity, but unemployment and inflation are both low. Using data from the US, UK and Canada, this column compares differences in the macroeconomic behaviour of real GDP, the inflation rate and the yields on three-month Treasury securities in the three countries. It shows that the Farmer monetary model, closed with a belief function, outperforms the New Keynesian model, closed with the New Keynesian Phillips curve. The data fit the multiple equilibria emphasised in the Farmer model well, rather than the mean-reverting processes assumed by the New Keynesian model.

Stephen Moore, President Trump’s pick for the Federal Reserve Board, has been pro-cyclical in his recommendations for monetary policy, opposing stimulus when the economy needed it and favouring stimulus when the economy did not. This column argues that Moore’s switch to urging monetary stimulus when Trump took office fits into a wider pattern among of pro-cyclical positions among leading Republicans, not just in monetary policy, but also fiscal and regulatory policy.

Cryptocurrencies have attracted the attention of consumers, policymakers and the media. This column investigates whether they can jeopardise the primary function of central banks, namely, controlling inflation and economic activity. Currency competition can succeed in calming inflation and preventing the sort of manipulation of interest rates and prices to which governments have historically been prone. But currency competition may also lead to government money losing the function of medium of exchange, which could be risky and lead government currency into further troubles.

The ECB’s market-neutral approach to monetary policy undermines the general aim of the EU to achieve a low-carbon economy. The column argues that steering the allocation of the Eurosystem’s assets and collateral towards low-carbon sectors would reduce the cost of capital for these sectors relative to high-carbon sectors. A modest titling approach could accelerate a transition to a low-carbon economy, and could be implemented without interfering with the priority of price stability.

Various factors have been advanced as possible causes of the build-up of risks leading to the Global Crisis, and multiple policies have been put forward to address them. This column discusses the effectiveness of monetary policy and macroprudential policy in responding to the build-up of risks in the financial sector. While both policies are useful, macroprudential policy is more effective in terms of financial stability and can lead to higher welfare gains.
