Administrative digitization in Germany
The digitization of public administration is making almost no progress in Germany. In a European comparison, the country continues to rank in the lower midfield in terms of e-government.

Europe must take the dare to take the next step: Delors Plan 2.0
In the coming years, the world order of exchange and multilateralism, which has so far been shaped by the West, will lose power, and global institutions will find it increasingly difficult to fulfil their mission of balancing interests and promoting international cooperation and development.

This time is different but still risky: Banking crisis instead of financial crisis
The current crisis of some American and European banks inevitably triggers fears that an international banking crisis could lead to a new financial crisis. But things in 2023 are very different from those in 2007.

Punching up or Punching down?: How Stereotyping the Rich and the Poor Impacts Redistributive Preferences in Germany
Redistribution and the welfare state have been linked by academic discourse to narratives that portray specific societal groups as ‘deserving’ or ‘undeserving’. The present analysis contributes to this scholarship in a twofold manner.

The Focus of Research in Germany’s Automotive Industry
The automotive industry in Germany is currently facing several challenges. Car production had already fallen significantly before the Covid19 pandemic and in 2020 and 2021 suffered two slumps of historic proportions.

China's dependence on the West for imports and technologies
There are mutual dependencies between China and the West that have the potential to result in high economic costs for both sides in the event of a geopolitical conflict. Should China actually plan an invasion of Taiwan, the West would be considerably affected by likely reciprocal sanctions, but due to its important position as a supplier of important goods for China, it would by no means be unable to act.

Immigration from North Africa: Initial successes and further potential for securing skilled labor
With the baby boomers retiring from the labour market, Germany will be increasingly dependent on skilled workers from abroad in the coming years in order to avoid massive bottlenecks in the labour market and to secure growth and prosperity.

Does Nudging Help in the crisis?: Behavioral economic measures for freedom-preserving energy conservation
In view of the impending gas shortage, private households are called upon to reduce their gas and energy consumption. The moral appeals of those in power harbor the danger that people will react with reactance instead of the desired change in behavior.

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.
