Over the cycle, monetary policy can be redistributional. Lower interest rates boost asset prices and lower borrowing costs but also increase employment and wages. But in the long run, monetary policy does not have systematic distributional effects; intergenerational transfers, globalisation, taxes and technological changes are the key fundamental drivers of inequality.

The Taylor rule provides a natural paragon of short-term nominal interest rates, albeit one that is subject to considerable uncertainty. This post quantifies this uncertainty and shows how this quantification contributes to monetary policy assessment. It shows that, in 2019, short-term interest rates in the euro area were close to the middle of the benchmark interval thus obtained.

Japan is a special case in that it is one of the first countries to face an ageing population. It is also unique in terms of the magnitude of this demographic: the proportion of people over 65 years old is the highest in the world and its population is expected to fall by 40% by 2100. Japan seems to have accepted this population decline and has focused on controlling welfare spending, which reflects national preferences.

This post proposes a measure of property purchasing power by calculating the floor area in m² that an individual with an average income could buy with a housing loan (excluding deposits) in some of the largest euro area countries. After declining sharply in the 2000s due to rising house prices (with the notable exception of Germany), affordable floor area has increased since the 2008 crisis, mainly thanks to lower interest rates.

At the end of 2018, “at-risk” firms in France were estimated to have total gross debts of EUR 187 billion. A 100 basis-point rise in their cost of financing could push this amount up by 60%, potentially posing a risk to the financial system. This result supports the measures taken by the High Council for Financial Stability (HCSF) as of 2018 to strengthen the resilience of the banking system.

The anchoring of inflation expectations results from an equilibrium between the private sector’s expectations of future central bank actions and the latter's actual actions. This equilibrium is often reduced to the question of a monetary policy rule. While the adoption of a rule helps in the formation of inflation expectations, it is not sufficient to anchor them permanently.

The net international investment positions (NIIP) of the G20 countries have diverged since 1990. While this divergence results partly from persistent imbalances in goods and services, NIIPs have their own dynamics: the portfolio generates income and capital gains or losses. These dynamics have had a stabilising effect at the cost of financial risks for some debtors, i.e. the United States, and an excessive accumulation of safe assets by some creditors.

Responding to China’s greater capital account openness, major investment indices have started incorporating renminbi-denominated securities. This is expected to support portfolio inflows into China and increase the correlation between domestic asset prices and external factors. The consequences for other emerging markets are uncertain.

While the duration of an expansion can intuitively be associated with its age, a study of historical GDP data for the euro area reveals that this is not the case. Old economic expansions are as likely to disappear as new ones. Like J. R. R. Tolkien's Elves, expansions are "biologically immortal": they do not die of old age, but of exogenous causes.

The Banque de France conducts a research patronage policy through partnerships and the action of its Foundation. The partnerships are collaborations with French research institutions, while the Foundation promotes research work by awarding grants and various prizes to researchers in France and abroad.
