Gas market shocks: tracing the effect on euro area inflation expectations

This paper examines the impact of natural gas market shocks on gas market dynamics, inflation expectations and realized inflation in the Euro Area using a BVAR model. Our contribution lies in a novel identification strategy that distinguishes between various types of shocks of unprecedented detail, leverages weekly rather than monthly data, and extends the analysis to both market-based headline and core inflation expectations.

European temporary migration in a two country DSGE model

Free movement of labour across borders can influence business cycle dynamics in the affected countries. This paper studies the macroeconomic implications of temporary migration using a two-country dynamic stochastic general equilibrium model calibrated to represent the “old” EU Member States (EU15) and the “new” Member States (NMS12). The model introduces fully endogenous temporary migration and combines it with search-and-matching frictions in labour markets.

Physical climate risk, credit risk and lending activity

We study how physical climate risk shapes bank lending activity and credit quality by combining high-resolution Copernicus flood geospatial maps with loan-level AnaCredit data. We exploit four major European floods (2021–2024) in a spatial regression discontinuity design comparing firms located just inside versus just outside flood boundaries (within 300–500 meters). We find that immediately after floods there is an increase by about 3.5 to 5% in lending, driven by liquidity demand, followed by a contraction of similar magnitude in the subsequent quarter.

Ex Machina: financial stability in the age of artificial intelligence

Does artificial intelligence (AI) pose a threat to financial stability? We study AI investor behavior, specifically Q-learning and large language model (LLM) investors, in a mutual fund redemption problem with economic and strategic uncertainty. Different AI architectures generate systematically different outcomes. Q-learning investors coordinate well but under default risk exhibit excessive redemption that amplifies fragility. LLM investors internalize equilibrium structure but display belief heterogeneity, weakening coordination and predictability.
