A new study by the HWWI confirms the enormous importance of sport for the Hanseatic city. “Sport is a powerful driving force for Hamburg,” emphasized President Prof. Norbert Aust, Senator for Sport Andy Grote, and HSB President Katharina von Kodolitsch at the presentation of the study. The study shows that sport secures around 15,000 jobs and generates added value of €5.3 billion. In addition to its economic importance, it also improves quality of life, promotes health prevention, and enhances Hamburg's attractiveness as a location. Sport is therefore much more than just competition – it moves the whole city.

A difficult international environment and a so far only tentative implementation of reforms by the new government – overshadowed by recurring disruptions within the coalition – continued to slow down economic development.

Does Disaster Aid Foster Political Popularity?

Does Disaster Aid Foster Political Popularity?

Using data from the United States as an example, the authors show that politicians can increase their political popularity—and thus their chances of re-election—by providing disaster relief. This effect is particularly evident among non-party-affiliated voters and lasts for about two years.

The German economy stagnated overall in the 1st half of 2025; German gross domestic product fell by 0.3% in the second quarter, as it had risen in the first quarter. Special effects (bringing forward production and exports to the first quarter due to expected US tariffs and mild winter weather) played a role in this, and the new government only took up its work in May and the economy initially waited for its reform plans.

Economic Policy Forum

The HWWI Economic Policy Forum serves the exchange between science, politics, associations, companies and the interested public. As part of this series of events, scientists give presentations on a current economic policy topic in a generally understandable form. Afterwards there will be an open discussion, which can then be deepened with a reception.

Forum Economic Policy

Research Colloquium

Within the HWWI Research Colloquium we regularly invite national and international scientists to give guest lectures at HWWI and discuss their latest research results. The seminar therefore primarily targets scientists.
