Dovish Coos or Hawkish Screech? From Central Bank Talk to Economic Walk

This paper investigates the effectiveness of the European Central Bank’s (ECB) communication in shaping market expectations and real economic outcomes. Using a transformer-based large language model (LLM) fine-tuned to ECB communication, the tone of monetary policy statements from 2003 to 2025 is classified, constructing a novel ECB Communication Stance Indicator. This indicator contains forward-looking ...

For a Strategic, European and Competition-Oriented Industrial Policy

The competitiveness of German industry is under significant pressure. While politiciansacknowledge the need for change, their proposed solutions remain vague and lack a clearstrategic direction. Current approaches focus on tax relief, broad investment subsidies fordomestic firms or targeted cost reductions, such as lower electricity prices. While thesemeasures may improve production conditions, they ...

Who benefits from economic growth?: The Macroeconomics Department at DIW Berlin

[English subtitles, German language video] The Macroeconomics Department at DIW Berlin investigates who benefits from economic growth and how economic changes affect different groups. The team analyzes current developments, assesses economic shocks, and provides sound forecasts. Through its work, the department supports policymakers and society in better identifying risks and opportunities and...

The Aggregate Labor Share and Distortions in China

This paper shows that in an economy where distortions prevent firms from using their profit-maximizing amounts of capital and labor, removing these distortions can generate both an efficiency gain and a higher aggregate labor share. We use firm-level data on Chinese manufacturing, mining, and public utilities in 2005 and estimate a general equilibrium model with heterogeneous productivity, technology, ...

Buyer Power and the Effect of Vertical Integration on Innovation

Our article investigates the impact of vertical integration (without foreclosure) on innovation. We compare cases where either (i) two manufacturers or (ii) a manufacturer and a vertically integrated retailer invest. Then, the independent manufacturer(s) and the retailer bargain over nonlinear contracts before selling to consumers. We show that vertical integration always increases the incentives to ...

Utilisation of Reactive Ionic Liquids for Energy Storage and Regulation of the Power Grid

Chlorine is an essential feedstock for polymers and pharmaceuticals, with annual production exceeding 100 Mt. Nearly all Cl2 is obtained by chlor–alkali electrolysis, which consumes about 2.58 MWh of electricity per tonne. Renewable energies such as wind and solar would lower CO2 emissions, but electrolysers would then have to adopt to fluctuating, renewable energies while downstream processes still ...
