The Bonn Intervention Panel (BIP) investigates the development of personality and preferences of children starting at the primary school age until age 25 and beyond. Main focus of our study is the impact of early childhood environment. In particular, we experimentally vary the childhood environment in our sample by giving a randomly chosen subgroup of the sample the opportunity to take part in a mentoring program.

The first part of the project, which have been completed in the fall of 2011, is measuring personality traits and preferences before the start of the intervention for all children (via choice experiments) and their mothers (or other main caregiver).

In the third wave (at the end of 2014)  the interview program bridges between the first two waves and the classical SOEP‐IS. The families answered the standard SOEP‐IS questionnaire batteries and the BIP child and the main caregiver (mother) answered additional batteries. The BIP child took part in incentivized experiments regarding time, risk and social preferences and answered the student questionnaire of the core SOEP. The mothers answered addition question regarding her personality and parenting style.

The 'BIP families' are since 2014 included into SOEP-IS and will be interviewed on a yearly basis to get information on the further development of the children.
