Why monetary policy should crack down harder during high inflation

04/29/2025 European Central Bank Central banks

The recent surge in inflation has led to a significant increase in the frequency of price changes, making prices more flexible. Conventional models assume a constant price change frequency, but in state-dependent models the frequency varies with economic conditions. Price flexibility has an impact on the effectiveness of monetary policy. In high inflation periods, frequent price changes make monetary policy more effective in reducing inflation with less impact on economic activity. Therefore, monetary policy should be more aggressive during such periods to stabilise prices efficiently.

The macroeconomic impact of euro area discretionary fiscal policy measures since the start of the pandemic

04/28/2025 European Central Bank Central banks

This box provides a model-based analysis of the impact of discretionary fiscal policy measures on economic growth and inflation since the start of the COVID-19 pandemic, as reflected in the March 2025 ECB staff macroeconomic projections for the euro area. Fiscal policy lent substantial support to the euro area economy in response to the pandemic and the energy crisis, while adding to public deficits and debt.

Mortgage refinancing and the marginal propensity to consume

04/24/2025 European Central Bank Central banks

This paper investigates the role of mortgage refinancing in shaping the estimates of marginal propensity to consume (MPC) and its implications for fiscal policy. Using U.S. household data, we find that MPCs decrease during the year of mortgage refinancing and stabilize afterwards, particularly among households with lower liquid assets, higher debtto-income ratios, and valuable illiquid assets. The empirical evidence suggests that refinancing provides extra liquidity, reducing MPCs.

Do central bank reforms lead to more monetary discipline?

04/09/2025 European Central Bank Central banks

This paper investigates the impact of reforms altering legal central bank independence (CBI) on monetary policy discipline and credibility, two key mechanisms shaping price stability. Using a sample of 155 countries over more than 50 years (1972–2023), we show that reforms improving CBI strengthen monetary discipline and the credibility of central banks. Larger reforms enhance monetary discipline with a lag, achieving their full effect after ten years. Central bank reforms have a greater impact on monetary discipline in countries that have not reversed earlier reforms.

Interest rate control and the transmission of monetary policy

04/02/2025 European Central Bank Central banks

We study how short-term interest rate volatility affects the transmission of monetary policy. To identify exogenous changes in volatility, we exploit the pronounced heteroskedasticity visible in the time-series of euro area short-term rates over the past two and a half decades. Interacting the exogenous variation in volatility with high-frequency-identified monetary policy shocks, we find that increases in volatility dampen the effects of monetary policy on output and prices.

Word2Prices: embedding central bank communications for inflation prediction

04/01/2025 European Central Bank Central banks

Word embeddings are vectors of real numbers associated with words, designed to capture semantic and syntactic similarity between the words in a corpus of text. We estimate the word embeddings of the European Central Bank’s introductory statements at monetary policy press conferences by using a simple natural language processing model (Word2Vec), only based on the information and model parameters available as of each press conference. We show that a measure based on such embeddings contributes to improve core inflation forecasts multiple quarters ahead.

Effects of monetary policy on labor income: the role of the employer

03/31/2025 European Central Bank Central banks

This paper investigates the role of firms in the transmission of monetary policy to individual labor market outcomes, both the intensive and extensive margins. Using German matched employer-employee administrative data, we study the effects of monetary policy shocks on individual employment and labor income conditioning on the firm characteristics. First, we find that the employment of workers in young firms are especially sensitive to monetary policy shocks.

The impact of regional institutional quality on economic growth and resilience in the EU

03/31/2025 European Central Bank Central banks

This paper investigates the impact of regional institutional quality on economic growth and economic resilience. Using data collected by the Quality of Government Institute, we conduct a two-way fixed effect panel regression model for around 200 European regions during the period 2010 to 2021. Our findings establish a positive relationship between institutional quality and medium-term GDP growth. This effect is more pronounced in regions with low-income per capita, highlighting the importance of asymmetries across European regions.

Private safe-asset supply and financial instability

03/26/2025 European Central Bank Central banks

This paper analyzes the private production of safe assets and its implications forfinancial stability. Financial intermediaries (FIs) originate loans, exert hidden effort toimprove loan quality, and create safe assets by issuing debt backed by the safe paymentsfrom (i) their own loans and (ii) a diversified pool of loans from all intermediaries. Ishow that the interaction between effort and diversification decisions determines theaggregate level of safe assets produced by FIs.
