In electricity markets, market power is typically measured by the difference between observed offers and underlying marginal (variable) cost of power production. Therefore, marginal cost estimates should be as accurate as possible to ensure unbiased measurement of market power and welfare-improving mitigation thereof. However, cost components and power plant characteristics are private information and firms have an incentive to overstate costs. Instead, system operators thus proxy marginal cost of power plants from past offers of the respective plant, which leaves room for strategic manipulation by firms. This article tests the accuracy of this best-practice benchmark approach against multiple suggested alternative methods. The results of our empirical analysis reveal a low estimation accuracy of the currently applied benchmark approach. All suggested alternative approaches deliver more precise estimates.

The Covid-19 pandemic hit Germany hard in 2020. Driven by the need to limit close contact and the resulting strict lockdown measures, economic activity fell sharply. To counter the effects of the Covid-19 pandemic, the German government introduced several policy measures. While the macroeconomic impact of the Covid-19 pandemic is well documented, evidence on the distributional impact on household income at the micro level is more limited. Our analysis shows that German households experienced a loss of over 3 percent of market income in 2020 due to the Covid-19 pandemic.

Europe is facing a whole new set of challenges: The cost of living is rising, war is on our doorstep, and an environmental turnaround is needed. How should the EU framework for economic governance change to make Europe stronger, more sustainable and more resilient? The European Commission has recently developed guidelines for a reformed economic governance framework. In March 2023, the European Council endorsed these guidelines. They aim at strengthening national ownership and facilitating the enforcement of projects. At the same time, they are intended to enable strategic investments and set a framework to reduce the high level of public debt. However, such economic policy coordination efforts at the EU level and the individual governance reform proposals open new debates. To what extent do they correspond to the real needs and interests of the EU? And do they take into account country-specific economic, structural and social problems of the member states?

Innovations form the backbone of sustained economic growth and, as such, they play a key role in safeguarding prosperity. Governments, aware of this, invest heavily in public research at universities and research institutes, and strive to create ideal conditions for private sector research and development (R&D), usually through specific R&D tax credit schemes or direct funding.

Narratives about immigrants matter for both natives and immigrants because narratives shape attitudes, political outcomes, and perceptions of discrimination. A recent and growing literature has shown that media narratives influence how people think and act as well as that specific framing of immigration matters for how migrants are perceived. However, no study has examined narratives about immigrants in a systematic way.
