This paper sheds new light on the role of communication for cartel formation. Using machine learning to evaluate free-form chat communication among firms in a laboratory experiment, we identify typical communication patterns for both explicit cartel formation and indirect attempts to collude tacitly. We document that firms are less likely to communicate explicitly about price fixing and more likely ...

As COP26 drew to a close earlier this month, almost 200 nations agreed to “phase down” coal power in the coming years. How this is done, for coal and other fossil fuels, will have implications for individuals and communities that depend on these resources for their livelihoods.
The case study conducted by DIW Berlin focuses on Germany and the efforts it has undertaken to support ...

Determining a robust mix of energy carriers for a carbon-neutral EU
Decarbonising the European energy system requires a fundamental transformation in the way societies provide, transport and consume energy. Disagreement exists over how this system should look in 2050. In this project, we prepared an overview report on the decarbonisation options for coal, natural gas, and hydrogen in Europe.
The...

Germany is leading in green competitiveness of its product exports. Deploying the green economic complexity methodology using German AFiD firm-level micro data, this study seeks to analyze explanatory variables for this trend such as green R&D subsidies and subnational density of related green technologies in the light of path dependencies in firms accumulation of green capabilities. It...

Research Project
In this report, the role of the Nord Stream 2 pipeline project for the German and the European natural gas market was investigated in the short run and the long run. In the short run, no supply gap can be identified that would justify the speedy finalization of construction works on the Nord Stream 2 project. In the long run, there is no need for the Nord Stream 2 pipeline due to the German and...

We consider a Green Public Procurement setting where the procurer provides a bid discount to environment-friendly technologies to foster their use. We assume that, before the auction, firms may switch to green technology via a publicly observable costly investment. We show that investment acts as a signaling device. This mitigates the effect of incomplete information on firms’ costs, thereby triggering ...

This paper discusses the potential role of fossil natural gas in the process of the energy transformation in Europe on its way to decarbonization. Mainstream conventional wisdom has it that natural gas, perhaps in combination with other gases, should maintain an important role in the energy mix, first, as a "bridge fuel", and then through a gradual transition toward "decarbonized gases". However, when ...

This paper aims to quantify the relation between real GDP, CO2 emissions, renewable and nonrenewable energy consumption, tourism development and labor force for France and Germany as these two countries are pioneer countries pushing Paris agreement within and outside the European Union. The time spans have been used for the period of 1995–2015 according to data availability. In the presence of cross-sectional ...

Different options for a reform of the EU Emissions Trading System are discussed to ensure carbon price incentives for mitigation options in the basic materials sector, while minimizing carbon leakage risks. This paper quantifies carbon leakage risks, distributional implications, and additional revenues associated with an import-only border carbon adjustment (BCA), a symmetric (import and export) BCA, ...

The energy transition requires substantial amounts of metals such as copper, nickel, cobalt and lithium. Are these metals a key bottleneck? We identify metal-specific demand shocks, estimate supply elasticities and pin down the price impact of the energy transition in a structural scenario analysis. Metal prices would reach historical peaks for an unprecedented, sustained period in a net-zero emissions ...
