This paper analyzes in a large-scale field experiment (N = 1425) whether gift vouchers
stimulate the use of a demand responsive transportation (DRT) system. This scenario is
compared to a situation where customers receive environmental certificates, which report
the saved carbon dioxide as a consequence of the bus ride. In our two treatments, the gift
vouchers and the environmental certificates could be gained by reaching to a certain threshold
of rides with the DRT service (EcoBus). We find that the demand went up more by gift
vouchers (83%) compared to certificates (65%). The data show that vouchers especially
outperform the certificates at the end of the treatment phase.
