The 30th anniversary of the European Single Market provides an opportunity to celebrate its successes and review what is yet to be achieved. In the future, the European Single Market will play a decisive role in setting a framework of reliable social standards and common goals. It will ensure Europe’s resilience by helping companies adapt their supply chains to future risks and find new business opportunities. The concrete measures of social policy will be left to the member states.

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.

The number of migrants is continuously increasing worldwide. One in 30 people is a migrant, which amounts to 3.6 percent of the world’s population. This article presents the case of Poland, a country with 12.5 percent of its population living abroad. Many of them still have Polish citizenship and thus the right to vote in Poland. It finds that, the large-scale emigration of young and educated voters causes a negative shift in left-wing voting while there is a substantial increase in right-wing voting with higher emigration. More generally, this effect will depend on the selection of migrants and their voting preferences. Based on this, countries might also want to apply different policies to steer the wheel in either direction.

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?
