[3] After the Deutsche Post Foundation, the sponsor, announced in 2023 its intention to merge the briq institute with the IZA, and IZA Director Simon Jäger subsequently announced his departure, Falk was slated to take over as the director of the combined institution.

In a broad sense, Falk's research is about obtaining a better empirical foundation of economic behavior.

In addition, Falk shows that social preferences such as fairness and trust are important determinants of behavior.

The research of Falk can broadly be divided into two main areas, the analysis of economic preferences and psychological aspects of the labor market.

A better understanding of preferences and personality is of great importance for economic and social science, as virtually every model in that area needs to make assumptions on individual behavior.
