Should the State Pension Scheme Take Different Socio-demographic Backgrounds into Account?
While German law stipulates a standard retirement age for all members of the public pension scheme, empirical studies have shown that life expectancy is unevenly distributed within the population, varying according to income level, professional status, occupational health risks, and gender.

Globalisation under pressure?: How current megatrends shape the patters of international trade, capital flows and technology diffusion
Deglobalisation, digitalisation, decarbonisation, and demographic change have already left their mark on the global economy. In the future the multiple transformations that the international patterns of specialisation undergo are likely to accelerate as the four megatrends mature and unfold their true disruptive potential.

The Importance of the Data Economy for Europe’s Digital Strategic Autonomy
European companies need to have the ability to store, process, use, and share data securely and autonomously, for example by using cloud services based on agreed quality standards, values, and legislation.

The impact of disrupted production on producer prices in Germany
From 2020 to 2021 the producer prices of manufactured goods in Germany increased by 6 per cent. However, price hikes accelerated during 2021, a development which has continued into 2022.

Do Family Businesses Shape Political Voting Behaviour in Germany?
In recent years family businesses have become an object of research in their own right. Indeed, it has been shown that, far from developing less dynamically than other firms, as once assumed, family businesses actually outperform their peers.

Pharmaceuticals in Transition: The Need for Skilled Labour in an Era of Digital Transformation
The shortage of skilled workers is increasingly confronting companies in Germany with major challenges. In view of the demographic and transformational tasks, there is a considerable danger that this situation will exacerbate.

Subsidizing Semiconductor Production for a Strategically Autonomous European Union?
The COVID-19 pandemic has highlighted the vulnerability of international supply chains and the dependency of the economy of the European Union (EU) on goods from non-EU countries. The scarcity of microchips that has persisted since the COVID lockdowns has laid bare the dependency of the EU on overseas producers of this essential high-tech product.

Fiscal and Economic Effects of Local Austerity
We study the consequences of a large-scale austerity program targeting financially-constrained municipalities in Germany. For identification, we exploit the quasi-random assignment of treatment among equally-distressed municipalities using a difference-in-differences design.

Towards a nuanced understanding of anti-immigration sentiment in the welfare state: a program specific analysis of welfare preferences
The literature on immigration and the welfare state describes a trade-off between immigration and welfare support. We argue for a more nuanced view of welfare chauvinism that accounts for different motivational channels, specific welfare programs and particular population subgroups.

Mutual dependence in trade between China, the EU and Germany
An inventory of the mutual dependencies in foreign trade between the EU and Germany on the one hand and China and Russia on the other is necessary in order to be able to make political deductions in these times of “Zeitenwende” on a sound empirical basis.

Understanding Science
- The scientific work of the German Economic Institute is independent and solution-oriented, internationally networked and socially relevant, methodologically open and interdisciplinary. We address the scientific discourse of experts, the general public as well as opinion leaders in politics, business and society. We want to be an audible voice in the economic policy discourse in Germany.
- Our work is innovative and confronts the scientific discourse: On the basis of scientifically recognized standards, we apply new methods, use new data sets, discuss new arguments and provide solution-oriented answers to current questions in economic analysis and economic policy. Our statements are theoretically founded and, where it is methodologically and empirically possible, evidence-based. We ensure that both the data basis and the methodological approaches are comprehensible. Modern methods of empirical economic and social research are as much a part of our tools as in-depth analyses of the institutional and political-economic conditions of economic developments.
- We do not exclude any theoretical and methodological approach, because diversity and competition promote progress in the sciences. The decisive factor is not a traditional paradigm, but whether and how a scientific approach leads further in the search for decision-guiding and action-relevant knowledge. Our research is not limited to economics, but is connectable to the debates and insights of other disciplines, such as ethics, history, education, political science, psychology, law, and sociology.
- Our research is aware of its normative conditionality. Every science of human social action requires a normative clarification of the concept of man. Freedom and (co-)responsibility are the central values for us. We see the human being as a being capable of freedom and responsibility, who in this sense is enabled and called upon to competent decisions and actions. In our view, open, liberal and democratic societies require a liberal and competitive economic order that counts personal responsibility and shared responsibility among its constitutive elements.
