Happiness Analyzer Smartphone Application

Short Description: Understanding whether nationally representative datasets can be collected using apps to collect data is crucial. To address this question, we built a new happiness app. In the first year (2015), participants did not receive any reward, and in the second year (2016), a different group of participants received a 50 Euro Amazon voucher for their participation.

Methodological Details: The eight chapter of Ludwigs’ doctoral thesis contains a detailed report of the methodology. pdf

Incentives: In the first wave of the module (2015), participants did not get any reward for using the study app. In the second wave (2016), they were offered a 50 Euro Amazon voucher for using the app.
