Our regular events

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.

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.
