Geography versus income: the heterogeneous effects of carbon taxation

08/27/2025 European Central Bank Central banks

The distributive effects of carbon taxation are critical for its political acceptability and depend on both income and geographic factors. Using French administrative data, household surveys, and matched employer-employee records, we document that rural households spend 2.8 times more on fossil fuels than urban households and are employed in firms that emit 2.7 times more greenhouse gases. We incorporate these insights into a spatial heterogeneous-agent model with endogenous migration and wealth accumulation, linking spatial and macroeconomic approaches.

The macroeconomic impact of trade policy: a new identification approach

08/25/2025 European Central Bank Central banks

This paper examines the effects of trade policy shocks on the US economy using a novel identification strategy that combines narrative information on trade policy changes with stock market data. We introduce a new data set of daily trade policy statements from 2007 to 2019, allowing us to capture a comprehensive range of trade policy actions. By analyzing stock price reactions of trade-exposed and non-trade-exposed firms around these statements, we can identify unanticipated trade policy shocks.

Heterogeneous intermediaries in the transmission of central bank corporate bond purchases

08/21/2025 European Central Bank Central banks

This paper studies the role of financial intermediaries in the transmission of central bank corporate bond purchases to bond yields. Contrary to standard expectations, we find that mutual funds—typically viewed as price-elastic investors—amplify, rather than dampen, the effects of these interventions on bond spreads.

From words to deeds – incorporating climate risks into sovereign credit ratings

07/29/2025 European Central Bank Central banks

We investigate the impact of climate risks on sovereign credit ratings worldwide. Our analysis shows that higher temperature anomalies and more frequent natural disasters – measures of physical risk – correlate with lower credit ratings. We find that long-term shifts in climate patterns (“chronic risk”) primarily affect advanced economies, while the increased frequency and severity of extreme weather events (“acute risk”) matters more for emerging economies. However, the estimated impact of both types of risk on credit ratings is low and the economic effects are negligible.

Climate change, firms and aggregate productivity

06/24/2025 European Central Bank Central banks

Our paper uses a general equilibrium framework to examine the effects of temperature on firm-level demand, productivity and input allocative efficiency. Using data from Italian firms and detailed climate data, it uncovers a sizeable negative effect of extreme temperatures on firm-level productivity. Based on these estimates, the model generates aggregate productivity losses from local temperature fluctuations that are higher than previously thought, ranging from 0.60% to 6.82% depending on the scenario and the extent of adaptation.

Private safe asset supply and financial instability

05/27/2025 European Central Bank Central banks

This article studies the supply of private safe assets by banks and its implications for financial stability. Banks originate loans and improve loan quality through hidden screening efforts. They can then create safe assets by issuing debt backed by the safe payoffs, from both loans they have originated and a diversified pool of loans from other banks. The interaction between banks’ screening efforts and diversification decisions determines the volume of safe assets they supply.

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.

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

03/26/2025 European Central Bank Central banks

This article investigates how firms transmit monetary policy shocks to individual labour market outcomes at both the intensive and extensive margins. Using matched employer-employee administrative data from Germany, we study the effects of monetary policy shocks on individual employment and of labour income conditioning on characteristics of workers and firms. First, we find that the employment of workers at young firms is especially sensitive to monetary policy shocks.

Critical input disruptions – mapping out the road to EU resilience

02/24/2025 European Central Bank Central banks

We study how disruptions to the supply of foreign critical inputs (FCIs) might affect value added at different levels of aggregation. FCIs are inputs primarily sourced from extra-EU countries with highly concentrated supply, or consisting in advanced technology products, or which are key to the green transition. Using firm-level customs and balance sheet data for Belgium, Spain, France, Italy and Slovenia, our framework allows us to assess how much – and how differently – geoeconomic fragmentation might affect European economies.
