DoCMA Working Papers

DoCMA Working Papers undergo an internal review process, in which all members of the DoCMA team are invited to make comments on the paper. Prior to publication, two professors must release the paper: One computer scientist or statistician and one communication scientist.

The first issue of DoCMA working papers was puplished in June 2020. It proposes a new taxonomy of economic uncertainty and constructs a news-based indicator that captures different kinds of uncertainty. Since then, we updated the UPI every quarter and refined the methodology. The latest UPI data is free for download. We have also constructed the Inflation Perception Indicator (IPI) in March 2022. Its results are regularly published in the German business daily "Handelsblatt".
