Green Transition in the Euro Area: Domestic and Global Factors (with Pablo García-Sánchez, Pascal Jacquinot, Crt Lenarcic, Kostas Mavromatis and Niki Papadopoulou). Conditionally accepted at the European Economic Review

We explore the macroeconomic effects of climate policies promoting the green energy transition in the euro area using an extended version of the Euro Area and Global Economy (EAGLE) model. The model differentiates between brown and green energy sectors and incorporates carbon taxes and brown capital income taxes. We analyze scenarios with unilateral and globally coordinated carbon taxes, with and without revenue redistribution to green firms and financially constrained households. Carbon taxes act as negative supply shocks, raising inflation and lowering output, while subsidies to green energy firms reduce green energy prices, supporting the transition and easing recessions. Redistribution to constrained households boosts consumption but does not accelerate the green transition. Taxes on brown capital income lower both inflation and output by acting as demand shocks. Recycling revenue from this tax to subsidize green capital investment strengthens the shift to green energy and moderates economic contractions. Global coordination of carbon taxes delivers only modest additional macroeconomic effects compared with unilateral action, as substitution in energy use outweighs international spillovers. Sensitivity analyses confirm the robustness of these findings under alternative assumptions about price rigidity, substitution elasticities and monetary policy.

The Pass-Through to Inflation of Gas Price Shocks (with Lucia López, Florens Odendahl and Susana Párraga). Revise and Re-submit at the Journal of Economic Dynamics and Control

This paper uses a Bayesian Structural Vector Autoregressive (BSVAR) framework to estimate the pass-through of unexpected gas price supply shocks on HICP inflation in the euro area and its four largest economies. In comparison to oil price shocks, gas price shocks have approximately one-third smaller pass-through to headline inflation. Country-specific results indicate gas price increases matter more for German, Spanish and Italian inflation than for French inflation, hinging on the reliance on energy commodities in consumption, production, and different electricity prices regulation. Consistent with gas becoming a prominent energy commodity in the euro area, including time-variation through a time-varying parameter BVAR demonstrates a substantially larger impact of gas price shocks on HICP inflation in recent years. The empirical estimates are then rationalized using a New Keynesian Dynamic Stochastic General Equilibrium (NK-DSGE) model augmented with energy. In the model, the elasticity of substitution between gas and non-energy inputs plays a critical role in explaining the inflationary effects of gas shocks. A decomposition of the recent inflation dynamics into the model structural shocks reveals a larger contribution of gas shocks compared to oil shocks.

Unexpected Expectations (with José-Elias Gallegos and Jaime Martínez-Martín)

We investigate the impact of monetary policy on economic agents' beliefs, using data from various surveys. We document that contractionary monetary policy shocks generate positive output and inflation forecast revisions, despite anticipation of higher policy rates, while conventional full information rational expectations models predict negative forecast revisions. We rationalize these findings by introducing information frictions, arguing that agents obtain information on the economic outlook during central bank announcements. Cleaning for the information effect, pure monetary policy shocks generate 25% larger responses. Furthermore, we examine optimal forward guidance strategies at the zero lower bound, contrasting promises of low interest rates versus targets about aggregate demand.

Adverse Noisy News in Times of Uncertainty (with Luisa Corrado and Donghoon Yoo)

We study the non-linear effects of noisy news about productivity in periods of low and high macroeconomic uncertainty. We first use a New Keynesian dynamic stochastic general equilibrium (NK-DSGE) model to extract aggregate noisy news from U.S. data. The measure illustrates that optimistic agents’ expectations are recovered after every crisis period with the exception of the Great Recession. Later, by employing threshold vector autoregression (TVAR) techniques, we show that adverse noisy news shocks lead to sizable and non-linear negative effects in macroeconomic aggregates under different uncertainty regimes, with the Federal Reserve responding firmly to noisy news during elevated uncertainty states. Over the course of time, we note potential benefits from falling uncertainty once the outcome of the noisy news shocks has been revealed.
